Shipping fast beats shipping perfect, every time.
PostWeavers drafts replies that sound like you and know what you know. You read, edit, and hit Post yourself. No automation. No ban risk. Your feed never leaves your browser.
Shipping fast beats shipping perfect, every time.
Tools should be quiet, sharp, and on your side of the table.
Every promise above is checkable. PostWeavers is open source under the AGPL, so you can read exactly what it does and what it never does: the code is on GitHub.
Click ✦ Draft in X's reply toolbar. It's already there, on every post. PostWeavers reads the post and thread you're answering.
Give it your rough thought (half a sentence is plenty) and pick a strategy: agree & add, contrarian, insight, humor, or your own. Topics you've saved on the subject come along automatically. The draft streams in, written against your learned voice profile.
Edit anything. Make it shorter, punchier, softer with one tap. Then you press X's Post button. The tool never does.
"Great point! Shipping fast is definitely a game-changer for startups. Speed allows teams to iterate and learn from real user feedback. Thanks for sharing this insight! 🚀"
fast is a speed. watching what breaks is a skill. teams confuse the two constantly
One click analyzes your recent posts into a style guide: length, casing, punctuation, slang, energy. It's stored as plain text you can read, edit, or delete. Every draft is woven against it.
Voice is how you sound. Memory is what you know. PostWeavers keeps two kinds, both yours to read and edit, both synced to your account: a note about who you are, and a pool per subject that you fill one good post at a time.
See a reply worth remembering? Click ⊕ under it and file it under a topic. Add a note, or your stance in one line. The next time you draft on that subject, the whole pool rides along, so the reply argues from what you've actually read.
The EU act keys on training FLOPs. That's a proxy, and proxies age badly.
One note, in your words, that every draft reads first: what you build, what you know, what you refuse to say. It's the difference between a reply that could be anyone's and one that could only be yours.
Founder of a dev-tools startup, ex-infra at a big cloud. Strong opinions on shipping speed and on AI hype. I've run on-call for a decade, so I don't romanticize velocity.
Never shill. Never hashtags. If I don't know, I say so.
Topics auto-select when the post mentions the subject or a keyword you set, and you can toggle any of them for a draft. Pin one to ride along in every reply.
$39–199/mo · quota-metered
Auto-DMs, auto-retweets, AI content firehoses. Fast numbers, on an account that X's automation rules say can be permanently suspended. Ask who carries that risk. (It's you.)
$12–29/mo
Great at queueing your own posts. But growth on X lives in replies, and a scheduler leaves you typing those alone.
free · or $12/mo Cloud
Drafts replies in your voice, at the moment it matters, and hands you the pen. Growth that's attached to a human, because it is one.
$0 bring your own API key
$12/month · no API key needed
For reference: the leading “growth platform” starts at $39/month and meters your DMs. We don't send DMs, and we think that's a feature.
No, and it can't. It drafts into X's own compose box; you read, edit, and press Post yourself. There's no auto-post, auto-DM, or auto-engage feature, because automated engagement is against X's rules and gets accounts suspended. Here's the full argument.
That's the whole product. PostWeavers learns a voice profile from your own recent posts (one analysis, stored as editable text), and every draft is written against it. If a draft feels off, you fix one line in the profile and every future draft obeys.
A memory per subject. Click ⊕ under any post on X to save it to a topic, add your own notes, and write your stance in a line. When you draft on a post that mentions that subject, the topic is pulled into the prompt, so the reply sounds informed and consistent with what you actually think. Topics and your About me note sync to your account, so every device shares them.
Free means the extension, with your own Anthropic, OpenAI, or OpenRouter API key plugged in. You pay your model provider directly, typically pennies a day. Cloud ($12/mo) is for people who'd rather skip keys entirely and want the mobile apps and sync.
In your browser, in local IndexedDB storage. PostWeavers doesn't scrape your account server-side and never sees your password. Only what you deliberately keep syncs to your account: settings, voice profile, About me, and the topics you save. Never your feed. Exactly what syncs, in the privacy policy.
SuperX is an automation platform: auto-DMs, auto-retweets, an AI content stream, $39–199/month. PostWeavers is a drafting tool: it helps you write replies in your own voice and refuses to act on your account. Side-by-side comparison.
