PostWeavers
AI drafts your X replies in your voice. It never posts.
PostWeavers drafts X replies that sound like you: a voice profile learned from your posts, topics built one saved post at a time, and a humanizer that strips AI tells. It never auto-posts, never DMs, never sees your feed. Open source. Free with your own key.
Hey PH 👋
I built PostWeavers because every "grow on X" tool forces the same bad trade: automate your account (and risk it, since X's rules on automated engagement are explicit) or paste generic AI replies (and sound like every other bot in the mentions).
PostWeavers refuses both. It learns your voice from your own posts, drafts a reply in it, and then it stops. You read it, you edit it, and you press X's own Post button. There is no auto-post, no auto-DM, no scheduler. Not as a policy I promise to keep, but as a thing the code cannot do, which you can verify because the extension is open source: https://github.com/lakshgandikot...
Two things I'd genuinely like feedback on:
1. Topics. You click ⊕ under any post worth remembering and file it under a subject. Later, when you draft a reply about that subject, everything you filed comes along, so the reply argues from what you actually read instead of from nothing. It is the newest part and the part I am least sure I have framed right.
2. The voice profile is a plain text style guide, not a black box. You can open it and rewrite a line and every future draft obeys. On top of that, every draft is checked against Wikipedia's "Signs of AI writing" list (the one WikiProject AI Cleanup maintains): stock words, flattery openers, em dashes, "not just X, it's Y", the lot. It fixes what it can as the draft streams and shows you what's left. I think this is the honest answer to "isn't this still AI slop," but I would like to be argued with.
Free forever with your own Anthropic, OpenAI, or OpenRouter key. $12/mo if you would rather never touch an API key.
Every reply I write in this thread today is drafted with it. Ask me anything.
