Best LinkedIn comment tools in 2026

There are three kinds of LinkedIn comment tool, and choosing the wrong kind matters more than choosing the wrong brand. Here are eight compared by how they work, what they cost and who they suit.

Disclosure: we make Commenty, so it is on this list. We describe every tool from its own website, say where each is the better choice, and show when we last checked. Spotted a mistake? Email contact@commenty.ai and we’ll fix it.

Three kinds of tool

Draft-and-review tools write a comment inside LinkedIn; you read it, edit it and post it.
Auto-comment agents find posts and comment for you, sometimes without you seeing each one first.
Sales conversation tools use comments and messages as part of tracking who to talk to next.

One rule affects the choice. LinkedIn’s User Agreement prohibits using bots or other unauthorized automated methods to comment on, like or share posts. Tools that leave the posting to you sit closer to normal use; tools that post for you carry more risk. We can’t speak for how LinkedIn enforces its rules.

Frequently asked questions

What is the best LinkedIn comment tool?

It depends on how much control you want. For drafting comments you review and post yourself, Commenty, AIReplyBee and Gromming are options. For hands-off commenting, Commenti or Commentify. For sales outreach, Commenter.ai or Extrovert.

Are AI LinkedIn comment tools allowed?

LinkedIn's User Agreement prohibits using bots or other unauthorized automated methods to comment on, like or share posts. Tools that draft and leave the posting to you sit closer to normal use; tools that post for you carry more risk. This is not legal advice, and no tool can guarantee how LinkedIn will act.

Is there a free LinkedIn comment generator?

Yes. Commenty has a free plan with 20 comments a day, AIReplyBee's free plan includes 10 replies a month, and Gromming has a free tier. Details change, so check each tool's website.

Do AI comments hurt your reach?

Generic AI comments can read as spam. Tools that learn your voice and leave the editing and posting to you tend to produce comments that sound more natural.
