Free LinkedIn Auto Commenter: What's Real and What's Bait
An honest map of free LinkedIn auto commenter options: free generators, browser extensions, free tiers and trials, plus the trade-off each one hides from you.
By Deepak Yadav, Founder, Ampliflow
The short version
- Most "free LinkedIn auto commenter" results are free comment generators you still paste manually, not tools that post on your behalf.
- Free rarely means costless. The usual price is session access to your LinkedIn account, a hard rate cap, thinner comment quality, or a tool that quietly dies in six months.
- Free is genuinely the right answer if you comment under roughly ten times a day, or if your account is new and should not be automated at all yet.
- LinkedIn's User Agreement prohibits third-party automation whether the tool costs nothing or costs $99, so price changes none of the account risk.
- Commenti is not permanently free. It is $19 to $49 per month billed yearly, with a 60-day free trial for the first 200 users.
What free actually costs
Free products are not charities. The cost just moves somewhere you do not see on the pricing page.
Rate caps. Every free tier is calibrated to be almost enough. That is the point of it. If your commenting plan needs 30 comments a day, a free tier built around 3 will feel like a demo, because it is one.
Session access. A tool that posts for you must operate inside your logged-in LinkedIn session, typically through a browser extension. That is not automatically bad. It is the safer architecture compared with handing over cookies or credentials, and the vendors doing it well say so loudly. But it means a free extension has standing access to a page where your inbox, your network, and your employer's data live. Check the permissions dialog. Check whether a privacy policy exists. If neither the pricing nor the policy tells you how the company makes money, you are looking at an incomplete picture.
Comment quality. Good comments cost inference. A free tool has a structural incentive to run the cheapest model with the shortest prompt, which is how you get "Great post, thanks for sharing" with extra adjectives. Generic comments do not just underperform, they actively read as automated to the humans you are trying to impress, which is the failure mode we mapped in are AI comments on LinkedIn good or bad.
Abandonment. This one bites hardest. Free LinkedIn extensions have a high mortality rate: LinkedIn changes its DOM, the side project stops being fun, the extension breaks, and your workflow evaporates on a Tuesday. Before you build a habit on a free tool, look at its last update date.
Account risk does not get cheaper because the tool did
LinkedIn's User Agreement prohibits using bots or unauthorized automated methods to access the service or to create, comment on, like, or share posts. That covers free tools, paid tools, and ours. We operate against that policy and we say so on every page where it matters.
Nothing about a $0 price tag softens that. What actually moves enforcement risk is behaviour: volume, speed, repetition, how generic the output reads, and how new or previously warned your account is. Free tools tend to correlate with higher risk for two boring reasons. They more often ship without daily caps, randomized pacing, skip filters, or a review step, because guardrails cost engineering time nobody is being paid for. And free pricing attracts exactly the user who wants to run 200 comments a day on a two-month-old profile.
Reduce is the only honest verb available to any tool here, including ours. If a free tool, or a paid one, promises your account cannot be caught, close the tab. We walk through the full picture in is LinkedIn automation safe, including the cases where our answer is do not automate.
When free is genuinely the right answer
There are real situations where we would tell you not to pay anybody, us included.
- You comment fewer than about ten times a day. A free generator plus your own reading is faster than configuring a tool, and your comments will be better.
- Your account is new, or has had a restriction warning. Automation is the wrong move at any price. Comment manually for a few months.
- Your niche needs genuine expertise per comment. If every reply requires a judgement call only you can make, automation is drafting overhead, not leverage.
- You have not proven commenting works for you yet. Test the channel by hand for two weeks using a LinkedIn commenting strategy first. If the manual version produces nothing, the automated version produces nothing faster.
Free stops being the right answer at a specific point: when you know commenting works, you are doing it daily, and the bottleneck is your time rather than your judgement.
Where Commenti sits, honestly
Commenti is $19, $29, or $49 per month billed yearly for 20, 40, or 60 AI comments a day. The tiers are built around 20-60 new followers a day; results vary by niche, profile, and account history. The first 200 users get a 60-day free trial. That is free to try, not free forever, and we would rather write that sentence than watch you find out at checkout.
Here is the product-design reason we do not run a permanent free tier, since this whole page is about free. Every comment we generate has a real per-comment model cost, so a free tier can only be paid for one of two ways: shipping a cheaper, worse model, or selling data. We are not willing to do either, so we sell the product instead. The 60-day trial is our compromise, and it is long enough to see whether the channel actually works for you.
The honest limitation: if you comment occasionally, or you enjoy commenting, Commenti is a worse deal than a free generator and your own hands. Our caps also mean you cannot buy your way to unlimited volume from us, deliberately, because volume is the single biggest driver of enforcement risk.

Frequently asked questions
Is there a truly free LinkedIn auto commenter?
There are free comment generators, which draft text you paste yourself, and there are free tiers or trials on paid auto-commenters. A permanently free tool that finds posts and publishes comments for you at real volume is rare, because every generated comment costs the vendor money in AI inference. Free plans exist mostly to demonstrate the paid one.
Are free LinkedIn comment Chrome extensions safe to install?
Read the permissions before you click add. An extension that drafts comments needs to read the page you are on, and one that posts for you acts inside your logged-in LinkedIn session. That is a lot of trust for a free product with no visible business model. Check who publishes it, whether there is a privacy policy, and whether it survives its next update.
Does a free tool get my account restricted faster than a paid one?
Not because it is free. Restrictions track behaviour, meaning how many comments you post, how fast, how generic they read, and how established your account is. Free tools do correlate with higher risk in practice, because they less often ship daily caps, randomized pacing, or a review step, and because free attracts volume-chasing usage.
What is the difference between a comment generator and an auto commenter?
A generator writes a comment and hands it to you. You still choose the post, read it, paste, and publish. An auto commenter chooses posts by your keywords or creator list and publishes without you present. The first is a writing aid. The second is automation, with the risk profile that comes with it.
Is Commenti free?
No, and we will not pretend otherwise. Commenti costs $19, $29, or $49 per month billed yearly for 20, 40, or 60 AI comments a day. The first 200 users get a 60-day free trial, which is free to try rather than free forever. If you want free forever, a generator plus your own hands is the honest answer.

A free LinkedIn auto commenter usually means one of four things: a free comment generator you copy and paste from, a free browser extension, a limited free tier on a paid tool, or a free trial. Only the last two actually post for you, and each one costs something that is not money.
We build Commenti, which is paid, so read this with that bias in mind. We are still going to tell you when free wins, because you will find out within a week anyway and we would rather be the page that was straight with you.
Four things a free LinkedIn auto commenter can actually be
The phrase covers products that behave completely differently once you install them. Sorting them first saves you an afternoon.
Planable's LinkedIn comment generator is a clean example of the first row: free, no registration, and it produces text you copy across yourself (verified July 2026). CommentWala is an example of the second: a Chrome extension that advertises unlimited free generation with no daily counters, and it still expects you to review the draft and hit send yourself.
Neither is automation. Both are useful. If you are comparing the writing quality of these, we went deeper on that in our breakdown of the LinkedIn comment generator category.
The tools that actually post for you, and how free they really are
Two names come up constantly here. We re-checked both against their live pages this week rather than trusting memory, and neither is free in the way the search phrase implies.
OutX markets its auto-commenter as free and runs it through a Chrome extension. The design detail we think is genuinely good: the page states plainly that it never asks for your LinkedIn password or cookies, and that comments fire through your real LinkedIn session with human-pace timing, daily caps, and working-hours filters. It also tells new users to start with two to three comments a day for the first two weeks and scale gradually, which is better advice than most paid tools bother to give. One thing we could not pin down, and you should: its pricing page does list a $0 tier, but the limits published against that tier describe watchlists, data freshness, and lead tracking, not a comment allowance. So the free plan exists. What it gives you in comments is something to test, not something you have been quoted.
PowerIn belongs in the trial column, not the free one. There is no permanent free plan. There is a five-day trial with no credit card required, and paid subscription tiers after it. Not asking for a card up front is a real courtesy and rarer than it should be. We have a longer head-to-head at Commenti vs PowerIn if you want the feature-level view.
One category note, because search results blur it constantly. Auto-commenting is not outreach. Tools like Dripify, Expandi, HeyReach, Dux-Soup, and Waalaxy send connection requests and DMs, which is a different activity with a different risk curve and different pricing. Commenti does not send connection requests or DMs at all. If your actual goal is free connection request automation, nothing on this page applies to you.
