Built for engineers and builders who have opinions but no time to back them up. Free 7-day trial, no credit card required.

Hey Product Hunt! 👋 I'm Amrit — solo founder, built PostWriter end-to-end. The problem I kept having: I'd see something interesting happen on GitHub or HN, have a take on it, open LinkedIn... and stare at a blank box for ten minutes before giving up. The idea was there. Turning it into words wasn't. So PostWriter does the research-to-draft step for you: → Tell it what you care about (AI, DevOps, cloud, whatever) → It scans GitHub Trending, Hacker News, Reddit, etc. daily → You get a draft already grounded in real sources — not generated from thin air → Edit one line, hit publish Every post comes with its sources attached, so what you say is something you can actually back up in the comments. Free 7-day trial, no card required. I read and reply to every piece of feedback myself — tell me what's broken, what's missing, what you'd want next. That's genuinely why I'm here today. — Amrit

Honestly the sources-cited angle is what got me, like that's the part that usually kills me when drafting on LinkedIn. Pulled a quick draft from a trending HN thread and the tone didn't sound like generic AI filler, which was kind of surprising.
