Composeur

Write your LinkedIn posts in your feed, and know what each line asks of whoever reads it.

Composeur writes your LinkedIn posts with AI from your own notes, and shows you, before you publish, what the AI added on its own. An AI tool asked for a post will happily supply the detail the genre expects: a client count, a percentage, a first name, a quote. It sounds plausible, it is false, and it is your name underneath. Composeur is built so you can stand behind every line you publish. WHAT COMPOSEUR DOES • Writes LinkedIn posts with AI. A subject or two lines of notes, a tone (expert, personal, direct) and a format (story, lesson learned, list, opinion, announcement). The draft arrives in about thirty seconds, right in your feed, without switching tabs. Spare first lines swap in with one click, and every version is kept. • Spots what the AI made up. Composeur compares the draft with your notes and flags every number, percentage, amount, date, proper name, quote or superlative that did not come from them. You fix it before you sign. • Analyses any LinkedIn post. A button under every post in your feed opens the reading in a side panel: passages are highlighted, the technique at work is named from Composeur's library of 34, and the goal of the post is stated in one sentence. Hook, length and readability are scored out of 5. • Writes in your style (Author plan). Paste a few of your own posts: the text keeps their rhythm, sentence length and turns of phrase, never their content. WHO IT IS FOR Freelancers, consultants, small-business owners and B2B salespeople who already post under their own name, about once a week, and answer for what they write. An alternative to ghostwriting and assembly-line copywriting: you sign it, with your own facts. Already writing posts with ChatGPT, Claude or Gemini? The free checker (composeur.fr/en/checker) lists what the answer added to your prompt, with no account and nothing stored. PRIVACY • The extension only works on linkedin.com. • It reads a post only when you click its button. What is sent for analysis: the text of the chosen post, its author's name, their profile link, the post ID and its public counters. Not your messages, not your profile, not the rest of your feed. • It never changes your feed and never posts anything there. No automation: no likes, no connection requests, no messages, no profile views. • With the Author plan, you can schedule a post from composeur.fr through LinkedIn's official sign-in, and only after you have approved it. • Full export and deletion of your data from your account. PRICING • Free: no credit card. 10 post readings and 3 written posts a month. • Author: €18 a month, or €15 a month billed yearly (€180). No quota on readings or posts (fair use), three first lines to choose from, your own style, calendar and LinkedIn scheduling. 7-day trial, cancel in one click. Create your free account at composeur.fr, then install the extension. It works on Chrome, Edge and Brave.
