Fezerli: AI Comment Generator for LinkedIn, Replies and Autopilot

AI comments for LinkedIn in your voice. Reads the whole post, images and PDFs too. Replies in DMs. Comments on Autopilot.

Fezerli is an AI comment generator for LinkedIn that writes in your voice, right inside LinkedIn's comment box. Click Comment under a post and the draft is already there: read it, change a word or two, press Post. The same AI drafts replies to your LinkedIn messages and connection notes, and on Pro it can comment on Autopilot by your rules. When you write by hand, nothing goes out under your name until you press Post. WHY ANOTHER AI COMMENT TOOL Most AI comment generators read the first lines of a post and produce "Great insights, thanks for sharing!" with an em dash in the middle. LinkedIn readers spot that in a second, and since July 2026 they can flag it as AI slop. Fezerli reads the whole post, the images, the carousel or PDF, the original of a repost and the top comments, then replies to one specific thing the author said. Every draft is checked for the usual AI giveaways (generic praise, em dashes, made up numbers, "it's not X, it's Y") and rewritten when one slips through. AI COMMENTS IN YOUR VOICE A few lines about you, your rules and up to ten of your own past comments shape every draft, so the comments sound like you and not like a bot. Ten tones, from Friendly and Witty to Direct and Respectful pushback, or leave it on Auto and it picks the tone that fits the post. Four lengths, from one line to a full paragraph. Pin your two favourite tones right in LinkedIn's comment box, next to emoji and GIF. Reads everything in the post. Text, images, charts and screenshots, carousels and PDF documents, reposts together with the original post. So the comment is about what the post actually shows, not just its first line. Tags the author properly. A real LinkedIn mention picked from LinkedIn's own list, not a typed name. Several people with the same name? It matches by profile photo. Emojis and the author's name can be switched off. Rewrite only what you want. Highlight a phrase in the draft and say how: shorter, warmer, less formal. Only that part changes. Click Comment again and you get a completely new angle on the same post. Add context. Met the author at a conference? Hover the Fezerli quill, type one line, and the draft builds on it. REPLIES TO MESSAGES AND CONNECTION NOTES Fezerli also works as a reply assistant in LinkedIn messaging: it drafts the next message in the context of the conversation. Saved templates cover the DMs and connection notes you send every week, with the name filled in. Search, arrow keys, Enter. 27 languages. It replies in the language of the post or the conversation, from English, German and Spanish to Ukrainian, Hindi and Japanese. AUTOPILOT: AUTO COMMENTS ON YOUR RULES (PRO AND TEAM) Autopilot comments in your LinkedIn feed while you do something else, by your rules: which posts (language, minimum reactions and comments, post age, author role, keywords, minimum length), how many a day and between which hours. It writes in your voice, types the comment letter by letter at a person's speed and posts it, then waits an uneven gap before the next one. It runs only while your LinkedIn tab is open and in front of you. Watchlist: set LinkedIn's bell to All on the people who matter to you, and their new posts go first. Country filter: keep Autopilot to authors from the countries you sell to. Stop list: people it must never comment on. Switching their bell off adds them automatically. Sensitive topics: politics, war, religion and grief are skipped. So are company pages and languages you did not choose. Mac and Windows app: keeps Autopilot running in its own window, so your everyday browser stays free. BUILT TO BEHAVE LIKE A PERSON Nothing runs on a stopwatch. The pace, the gaps and the daily cap shift a little every day. Clicks land where a hand would, the feed scrolls the way a person scrolls, typing has the small pauses people make, and a post is always on screen before anything happens to it. Switch to another LinkedIn tab and Autopilot pauses mid sentence; come back and it finishes. If LinkedIn changes its layout, Autopilot backs off and stops itself instead of clicking blind. An honest note. LinkedIn's User Agreement does not allow automated commenting, so any tool that posts for you carries some risk of a restriction. Autopilot stays off until you turn it on and confirm that you understand this. Drafts you read and post yourself are no different from typing them. PRIVACY AND PERMISSIONS Fezerli works only on linkedin.com, inside the LinkedIn you are already logged into. It never asks for your LinkedIn password and never uses "Sign in with LinkedIn": your Fezerli account is a one time code sent to your email, so it is not linked to your LinkedIn login. To write a draft, the post you are commenting on (or the conversation you are replying to) is sent to Fezerli's servers and from there to the AI model that writes the text. That is all it reads. No browsing history, no contacts, no scraping of profiles or feeds. PRICING Start free: 50 AI drafts with every feature, Autopilot included, no credit card and no signup.
