The problem we're solving is one most engineers have lived but rarely talk about openly real customer data ending up in staging environments, CI pipelines, and demo setups because there's never been a fast enough alternative to just copying production.
I've been using AI coding agents (Claude Code, Cursor, Codex, aider ) to work with open source repos, and I noticed a scary gap:
You git clone a project, you point an agent at it, and before you type a single command, code can already run.
A .git/hooks/pre commit, an npm postinstall, a .envrc, a VS Code task set to folderOpen, a CLAUDE.md that tells the agent to curl | bash none of these show up in a normal diff review.
Every week an AI launch shows up claiming "10x faster" or "beats every benchmark". Some of it is real. A lot isn't. Finding out costs 20-30 minutes of digging through benchmark tables and dev threads.
So I built Reality Filter. You paste in a launch and get one verdict: worth trying now, watch later, too early, or mostly fog machine - plus a fog meter for how much of the claim is still unproven. Every verdict names its sources: real benchmark numbers, named reviewers, actual user reports. Never "reports suggest".
I built BabyPercent, a free browser-based baby growth percentile calculator for parents who want to understand weight, length, and head-circumference charts before a pediatric visit.
The product boundary is important: a percentile is a comparison, not a grade, and the trend across visits matters more than one isolated number. The tool is educational and does not diagnose.
Spent years in Amazon KDP self-publishing and always hated writing book descriptions from scratch.
So I built PublishAI you enter your book topic, pick a genre, add keywords, and get a full book description, title ideas, and Amazon keywords in seconds.
It's completely free right now. No signup required.
Would love feedback from anyone here who writes, publishes, or knows authors who struggle with this. What would you add?
Update: we're live on Product Hunt! If anyone wants to try it kdp-tool-nu.vercel.app totally free. Would genuinely love to know what feature you'd want next: bulk generation, genre-specific templates, or something else?
