XposterAI: AI reply generator for X/Twitter

Hey Product Hunt 👋

Quick note before the story: we're officially launching here on June 2nd. If you tap Follow above, you'll be notified the moment we go live.

I shipped the first public version of XposterAI 8 months ago. Since then it's been a lot of nights, weekends, and small iterations — built

around a full-time job and family life, in the cracks where I could find them. 331 commits later, this is the version I'm finally proud to show

you.

The honest origin story: I wanted to reply to interesting people on X, but every AI tool I tried sounded like a corporate template. The replies

were generic. They didn't sound like me. I'd post one and immediately regret it.

So I built Persona Studio — train an AI voice fingerprint on your own tweets, then every reply comes back sounding like you wrote it.

Trained-status badges, freshness reminders when a persona's gone stale, per-language personas, the works. This is the

feature I'm most proud of, and the thing other tools seem to either skip or fake.

A few other things I shipped along the way that I think are worth pointing at:

- Reply Strategy + Tone selectors — pick the conversational move (ask a question, contrarian angle, personal anecdote, soft promo) on top

of the tone, so replies actually move conversations forward instead of just agreeing.

- 3 variants per generate, 1 click to improve any of them — don't burn 3 fresh credits to refine the one you almost liked.

- Saved replies — bookmark the winners and build a swipe file of what your audience actually responds to.

- 50+ free creator tools at xposterai.com — character counter, thread splitter, hook analyzer, Twitter archive viewer, posting calendar,

profile audit. No signup, no card. Use them whether or not you ever install the extension. This part was important to

me — building tools the community can grab for free regardless of whether they pay for the AI side.

30 free credits on signup so you can try before deciding. Privacy-first — no tracking, no selling data.

If you've ever felt the writing burnout from trying to grow on X, or felt weird about AI tools that make every reply sound the same — I'd

genuinely love your feedback ahead of launch. What's missing? What's confusing? What other tools would be useful in

the free tools collection?
