Free LinkedIn post tools, sorted into the two kinds that matter

Most free tool lists are affiliate pages. This one sorts the options by whether they check what you wrote or write it for you, which is the only useful split.

The short answer

Free tools for LinkedIn come in two kinds. Checkers read writing you already produced and report something measurable about it. Generators produce writing you did not. A checker can improve a writer and can be safely ignored. A generator replaces the part of the work that carries your judgement, and readers who know you can hear it. Build the free stack from checkers and capture tools first, and treat generators as outline help only.

Free tools split into two kinds, and only one of them improves a writer

Sort free LinkedIn tools by what they do to your draft, not by price or popularity. A checker reads writing you already produced and reports something measurable: sentence length, reading level, how many posts opened the same way, how long the thing runs before the point arrives. A generator produces writing you did not. Most tool lists mix the two into one ranking, which is why the ranking never helps anybody choose.

About the two services named in this piece

Two options in the comparison below, Supersonify and Ra-Aha, are sister services run by the same team that publishes this site. They appear because they occupy routes the free tools genuinely cannot cover, not because they are cheap and not because they are the right answer for most people reading a page about free tools. Weigh the relationship, and read every entry's downside, including theirs.

The split matters because the two kinds fail differently. A checker that you ignore costs you nothing. A generator that you accept without rewriting puts sentences under your name that you did not think, and the people who already know how you talk can hear the difference in one scroll. That is the entire risk surface of this category, and all of it sits on one side of the line.

  • A checker cannot run on an empty page. If the tool produces something from a prompt alone, it is a generator whatever the marketing calls it.
  • A checker is measuring text. It holds no opinion about whether your argument is true or whether the post is worth publishing.
  • A generator has no access to the meeting you sat in, the number on the dashboard you saw on Tuesday, or the sentence a customer said that annoyed you. It fills that space with the average of everything written before.
  • Both kinds are useful in the right slot. Only one of them can be wrong about your subject.
3%

Around 3% of members post more than once a week. Almost nobody is being held back by a missing text editor. The week that gets skipped is a calendar problem and a nerve problem, and a tool that assumes you already write regularly has nothing to say about either.

Diagnose the failure in your last five posts before you install anything

The tool question sits downstream of a diagnosis, and skipping the diagnosis is how people end up with six browser extensions and the same flat posts. Read your last five posts in one sitting and name what is actually wrong. Most complaints resolve into one of six failures, and only three of them have a tool answer.

What is actually wrongThe kind of tool that helpsWhat the tool will not fix
The post rambles and the point lands in the final lineA structure checker, or the older method of reading it aloud onceThe reason you buried the point, which is usually that you were not sure of it
Sentences run long and readers drop out halfwayA readability checker set to flag any sentence over 25 wordsWhether those sentences are saying anything worth the length
Every post opens the same way and the feed skips youAnything that counts your opening lines across posts, including a plain spreadsheet of your last twentyThe narrow range of ideas underneath the repetition
You have nothing to say this weekNone. This is a capture failure, not a writing failureA generator will hand you text on the subject and it will read like nobody wrote it
You have plenty to say and no hour in which to write itA voice recorder and a free transcriptThe editing pass, which still needs you or somebody you trust with your name
Drafts are good and nothing happens after you publishNo writing tool at all. Look at positioning, profile and who is actually reachedThe tool budget you were about to spend on the wrong problem

Six common failures, three tool answers. The other three are answered by process or by a person, and no free stack changes that.

Two of those six rows point away from tools entirely, which is the honest finding of the category. If row five is yours, the useful comparison is not between browser extensions, it is between your hour and somebody else's. The arithmetic in what a LinkedIn ghostwriter costs is about buying back exactly those hours, and it is the same maths whichever way you decide.

What a free checker can see, and the three things it cannot

A checker gives you a second reading of your own draft by somebody who is not tired of it. That is worth real money and most of them are free. What it sees is surface structure, and surface structure is a genuine problem for executives who write the way they present, in long qualified sentences built to survive a room full of objections.

  • Sentence length, which is the single most reliable predictor of whether a post reads easily on a phone.
  • Repetition, both of words inside a post and of openings across posts, which you stop hearing after about the fifth draft.
  • Paragraph mass, which on LinkedIn matters more than on a page, since a wall of text collapses under the see more fold and never gets opened.
  • Passive constructions and hedges, which are where the specific claim you were nervous about goes to hide.
A readability score is not a clarity score

Reading level formulas are computed from sentence length and word length. They cannot tell whether a sentence is true, specific, or yours. A post made entirely of short vague sentences scores beautifully and says nothing, which is exactly the failure mode of a writer optimising for the number. Use the score as a flag to look at a sentence, never as a target to hit.

The three things no checker sees are the ones that decide whether the post works. It cannot tell you whether the claim is defensible, whether the story is yours to tell, or whether anyone in your market needed this said. Those are editorial judgements, they arrive from knowing the reader, and they are the reason a good editor is expensive and a checker is free.

What a free generator gives you, and what it quietly takes

A generator is genuinely good at three narrow jobs and poor at the one you want it for. It is good at rearranging material you supply, at producing five possible orders for an argument you already made, and at telling you what the obvious version of your point sounds like so you can avoid writing that. It is poor at having the point.

  1. Safe use: paste in a transcript of yourself talking for eight minutes and ask for the three arguments inside it. You supplied the thinking, and you are asking for an index.
  2. Safe use: ask what the average post on your topic claims, then write the paragraph that disagrees with it. The generator is a map of the crowded ground, which makes it useful as a thing to move away from.
  3. Risky use: asking for a finished post about a topic you have not thought through. The output will be fluent, it will be an average of the internet, and you will publish something you would not defend in a meeting.
  4. Risky use: asking it to rewrite in your voice from a two line description of your voice. It has no sample of you, so it produces the genre, not the person.

The tells that follow a generated draft into publication are consistent and easy to spot once named. Sentences arrive in balanced pairs where the second half negates the first. Three word fragments get stacked for rhythm. Every paragraph is the same length, because nothing in the draft came from a person who got bored partway through and cut the ending short. None of that gets flagged by a checker, because structurally it is immaculate.

51%

51% say text posts are what they most engage with. A tool that mainly produces graphics and carousels is solving a format problem you may not have, and it costs a great deal more of your time per post than a plain draft does.

What to take away
  • The only sort that helps is checker against generator, because a checker measures a draft you already wrote while a generator supplies the thinking you were supposed to do.
  • Diagnose the failure in your last five posts before you install anything, because three of the six common failures have no tool answer at all.
  • Under the stated assumptions in this piece, the whole free tool category is worth between 12.5 and 37.5 hours a year, while changing who writes the first draft is worth around 95.
  • Readability scores are computed from sentence length and word length, so a post can score well and still say nothing a reader needed.
  • If your drafts are fine and nothing happens after you publish, the problem is positioning or audience, and no writing tool touches either.

The Check Or Generate Split, a four question test for any tool

Every new tool arrives claiming to be a writing assistant, which is a category name designed to blur the line this whole piece is about. Four questions place any tool on the correct side of it in under a minute, before you build a habit around something that should never have touched your drafts.

The Check Or Generate Split
Run any free tool through these four questions. The answers tell you what kind of tool it is, what it may touch, and what evidence you need before trusting it.
Does it need a draft to work?Open it with an empty page and try to make it produce something. If it can, it is a generator. This matters because a generator earns a place only after you have supplied the raw material, and the order of operations is the whole safety mechanism.
Can it be wrong about your subject?A checker counts things and cannot be wrong about your industry, because it has no view about your industry. A generator can be confidently wrong about a regulation, a number or a competitor. Anything that can be wrong needs a fact pass by somebody who would know, which is a cost you should count.
What does it hold after you close the tab?Free tools are paid for somehow. Before you paste unannounced results, an internal disagreement or a client name into a free box, read what the tool retains and what it trains on. The rule that survives contact with reality is simple: nothing goes in that you would mind seeing quoted back.
What does it cost in minutes, not money?Time the tool honestly across three posts. Count the minutes it saves in drafting and the minutes it adds in cleaning up. Several popular free tools are net negative on this measure and nobody notices, because the drafting minutes feel like work and the cleanup minutes feel like polish.

The routes compared, free options first and paid ones last

Below are the routes available to somebody who wants better LinkedIn posts, ordered by how many readers of a page about free tools each one actually fits. The free routes come first because that is what you came for. Nothing here names a third party product, because pricing and positioning for those change monthly and cannot be verified from a blog post, and inventing them would be worse than omitting them.

A plain text editor and a protected weekly slot

The baseline free stack is a notes app you already own and one hour blocked in your own calendar with the door shut. No installation, no account, no data leaving your machine.

Best forAnybody who has not yet published consistently for eight weeks. Until the slot exists, no tool has anything to operate on.
Costs youNothing in money. Roughly 45 to 60 minutes per post of your own attention, and that attention is the actual price of this entire category.
Watch outIt relies entirely on discipline, and discipline fails first in the weeks when work is heaviest, which are also the weeks you have the most to say. Nothing in this route catches you when you stop.
A free readability and structure checker

A browser based tool that reads a draft you paste in and flags long sentences, dense paragraphs and passive constructions. It measures the shape of the writing and reports back.

Best forExecutives and consultants whose drafts are thoughtful and unreadable on a phone, which is the most common writing failure among people who present for a living.
Costs youFree tiers are normal across the category and change often, so check the current tier before you build a habit. Two to four minutes per post of your time.
Watch outIt has no view on whether the post is worth publishing, and chasing a good score pushes writers towards short vague sentences that score well and land nowhere.
LinkedIn's own drafts and post analytics

The platform saves unfinished posts and reports impressions, members reached and engagement per post. Free, native, and the only data source here that reflects what actually happened to your writing.

Best forAnyone guessing about what worked. Twenty posts of your own analytics beat any published benchmark, because they are measured on your audience rather than somebody else's.
Costs youNothing in money. Around 20 minutes a month to record the numbers somewhere you can compare them across a quarter.
Watch outDrafts are saved per device and are easy to lose, so keep the master copy outside the platform. The analytics also under report the effect that matters most, which is the person who read you for three months and then sent one message.
A phone voice recorder plus free transcription

Talk for eight minutes about the thing that annoyed you this week, transcribe it, then cut the transcript down into a post. The capture route rather than the writing route.

Best forPeople who are articulate in meetings and stiff on the page, which describes most senior operators. It solves the blank page by removing the page.
Costs youFree on most phones. Around 10 minutes to talk and 25 to cut, so it does not save much time, it changes where the difficulty sits.
Watch outSpeech is repetitive and unstructured, so a transcript needs harder editing than a draft does. Skip that pass and you publish something baggy that sounds like a person clearing their throat.
A general purpose AI assistant on its free tier

A chat tool used as a generator. Free tiers exist across the category, with limits that shift, and all of them will hand you a complete post on request.

Best forOutlining, finding the three arguments inside your own transcript, and seeing what the obvious version of your point sounds like so that you can write something else.
Costs youFree tiers are usual and the limits move. The real cost is the editing minutes needed to remove the tells, which for most people cancels the drafting minutes it saved.
Watch outIt has no access to your week, so it substitutes the average of everything written on your topic. Published unedited, it costs you the readers who know your voice, and those are the readers who send the messages that matter.
Ra-Aha sister service

LinkedIn profile and positioning advisory for individual founders and executives. It works on what you stand for, how the profile reads, and which audience you are addressing, rather than on producing your weekly posts.

Best forThe reader whose drafts are already competent and whose posts still go nowhere, which is row six of the diagnosis table above. That is a positioning problem and no free tool touches it.
Costs youPaid advisory, plus several hours of your own time in interviews and revisions. Advisory is priced on attention, so the fee scales with how much of it you use.
Watch outIt will not fill an empty publishing calendar. If nothing is getting written at all, better positioning simply gives you a sharper description of the posts you are still not writing.
Supersonify sister service

Runs LinkedIn as a growth channel for B2B companies and teams: ads, the company page, employee advocacy and pipeline reporting. Company level work rather than one person's writing.

Best forA company with a marketing team, a budget and a pipeline target, where the question is channel performance rather than whether your own drafts read well.
Costs youAn agency retainer plus media spend, plus internal hours from marketing and from whoever approves creative. There is no free version of this route.
Watch outIt is the wrong shape for a single executive writing personal posts, and the wrong answer for anybody who arrived at a page about free tools. Company channel work does not sit down and write in your voice.

The two sister services sit at the end for a reason worth stating plainly. This page is read by people who want their own writing to improve without spending money, and for that reader the first four routes do more than either paid option would. A paid route becomes the right answer only when the diagnosis says the problem is positioning or capacity rather than craft, and the diagnosis is upstream of every vendor decision.

What the free stack actually costs you in hours

Free tools are not free, they are paid for in your attention, and the only way to compare them honestly is to price that attention at a number you choose. Everything in the table below is an assumption stated out loud rather than survey data, and every input is yours to replace before you redo the division.

Route (all inputs assumed)Your minutes per postYour hours a yearYour time valued at 150 an hourMoney you pay out
You write it, no tools at all5012518,7500
You write it, checkers in the loop45112.516,8750
Generator first draft, then your rewrite4010015,0000 on a free tier
Voice note captured, then you cut it down3587.513,1250
Interview led production by somebody else12304,500The fee, whatever you agreed

Illustrative arithmetic on stated assumptions: three posts a week across 50 weeks, so 150 posts a year, with your own hour valued at 150 units of currency purely to make the maths visible. Replace every input with your own.

Read the gaps rather than the totals. Adding every free checker to your process is worth about 12.5 hours a year on these assumptions, and switching to voice capture is worth about 37.5. Handing the first draft to another person is worth roughly 95 hours, which is why the tool argument is small and the ownership argument is large. If that gap is the live question for you, the crossover maths in per post pricing against a monthly retainer picks up exactly where this table stops.

Assemble the free stack in this order

Order matters more than selection, because each step only pays off if the one before it exists. Most people start at step four, which is why the tools get abandoned by the third week and blamed for the failure.

Book the slot before you install anything

One hour, same day each week, in your own calendar, defended like a client meeting. Until this exists you do not have a writing process, you have an intention, and no software improves an intention.

Start a capture file

One document, permanently open, where every annoyance, number and overheard sentence goes the moment it happens. Twenty lines in that file is the difference between the blank page and an editing job, and it removes the only failure a generator is ever hired to solve.

Write badly and finish

A complete bad draft can be checked, cut and rescued. Half a good draft cannot. This step is where most free stacks quietly die, because the tools all sit downstream of a finished draft and nobody says so.

Run one checker, not four

One pass for sentence length and paragraph mass, then stop. Multiple checkers disagree with each other and the disagreement becomes a way of avoiding the publish button for another day.

Read it aloud and cut the first two lines

The mouth catches what the checker misses. The opening you wrote is almost always a run up to the real first line, which is sitting in position three, and deleting the run up is the single highest yield free edit available.

Record what happened

Impressions and replies into a simple sheet after 48 hours. After twenty posts you own a private dataset about your own audience, which outranks every published benchmark you will ever read, including the ones in this piece.

What no tool can do, at any price

Some work cannot be delegated to software and it is worth knowing which parts before you spend a Saturday comparing extensions. The list below is what remains yours regardless of the stack, and it is also a fair test of whether a paid service is worth it, since a good one takes on the middle items and hands the rest back to you.

Stays with you whatever you install
  • Deciding what you actually believe about your market, which is the raw material for every post you will publish this year.
  • Noticing the thing worth writing about on the day it happens, because nobody else was in the room.
  • Approving your own name on a claim, including the risk that a customer or a regulator reads it.
  • Replying to the person who comments, which is where the business in this channel is generated and where automation is most obvious and most damaging.
  • Deciding to stop a format that is not working, which requires reading your own numbers rather than your own feelings.

If you are weighing a paid route against the free stack, the practical test is whether the arrangement gives those five back to you or quietly takes them. The interview questions in questions to ask a ghostwriter are built around exactly that division of labour, and they work as a filter for services and software alike.

Questions people ask next

Are free LinkedIn post tools good enough to replace hiring a writer?
No, and they are not competing for the same job. Free checkers improve a draft you already produced, so they raise the floor for somebody who writes weekly. Hiring somebody removes the writing hours from your week entirely. If your problem is quality, free tools help. If your problem is that nothing gets written, they do nothing at all.
Does using an AI tool to write LinkedIn posts hurt your reach?
There is no published figure we can point at that settles this, and most people quoting one are quoting themselves. The mechanism that reliably matters is human rather than algorithmic. Readers who know how you speak notice when specificity drops, they stop replying, and posts without replies from real people fade quickly regardless of what any ranking system is doing.
What is the cheapest way to post consistently without writing every draft myself?
Voice capture, on the arithmetic in this piece. Talking for eight minutes and cutting the transcript costs roughly 35 minutes per post against 50 for writing from scratch, and it removes the blank page rather than the thinking. The next real saving after that is another person doing the first draft, and that one costs money.
How do I stop my posts sounding like they came out of a template?
Put something in every post that only you could have written: a number from your own dashboard, a sentence a customer actually said, a decision you regret. Templates and generators cannot reach any of that. A useful weekly test is whether a competitor could publish your post unchanged, and if they could, the post was about the category rather than about you.
Should I spend on a tool subscription or on a person?
Diagnose first. Tools address structure and consistency, so a subscription is defensible if you write regularly and read badly on a phone. A person addresses capacity and judgement. If you have skipped three of the last five weeks, no subscription fixes that, and the honest comparison is between your hourly rate and somebody else's fee.
