PostWeavers
install

Up and drafting in one minute.

PostWeavers is a Chrome extension. It drafts replies in your voice, in a side panel, on x.com. It never posts anything. You do.

Add to Chrome, free

On the Chrome Web Store · Chrome / Edge / Brave / Arc · no account needed to start

After you click Add

  1. Chrome asks you to confirm. Click Add extension.
  2. Pin PostWeavers from the puzzle-piece menu so it's one click away.
  3. Open x.com and click into any reply box, or press Cmd+Shift+S (Ctrl+Shift+S on Windows) to open the side panel.

First two minutes

  • Pick how drafting runs. Settings → AI Drafting: PostWeaver Cloud (no key, free tier included, $12/mo for more) or My own key (Anthropic, OpenAI, or OpenRouter: free forever, you pay your provider pennies).
  • Teach it your voice. One click analyzes your own posts and distills a style guide it reuses on every draft. Drafts stop sounding like a bot because they're built from you.
  • Give it memory. The Context tab holds an About me note that every draft reads, plus topics: click ⊕ under any post on X to file it under a subject, add notes, and the pool rides along whenever you draft on that subject.
  • Reply. Click into a reply box on X, jot a rough thought (or don't), pick a strategy, and hit Draft. Read it, edit it, and press Post yourself. Always.

What it will never do

No auto-posting, no auto-DMs, no scheduled engagement, no acting on your account while you sleep. That's not a missing feature. It's the entire point, and it's what keeps your account on the right side of X's automation rules.
