Who hunted XposterAI?
XposterAI was hunted by Diypreneur. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

Hey Product Hunters,
I was writing 20+ replies a day on X and half of them sounded like
everyone else's. The good ones took 5 minutes each; the fast ones
were forgettable.
Built XposterAI solo, around a full-time job and family, so my
replies actually sound like me — at the speed of a single right-click.
What you get inside X:
- Replies in your tone (witty / professional / your trained voice),
3 variants per click — pick the strongest, post it
- A "reply strategy" selector so the reply moves the conversation
forward (question, contrarian, anecdote, soft promo)
- Persona training on your own past tweets, per-language — so the
AI doesn't flatten your voice into ChatGPT default

Honest ask — what's the kind of reply you keep retyping and never
feel good about posting? That's the one I want to make easier next.
