Capafy is a marketplace for Skill-based Agents. On Capafy, a Skill runs as an Agent — it puts the Skill's ability to work as a service. The user uses what the Skill does — make a viral video, screen a resume, write a cold email — without ever holding the Skill itself.
Hey everyone 👋
I'm the maker behind HookCraft Studio.
I built this because I run a YouTube channel myself, and the part that took the longest wasn't filming or editing — it was staring at a blank page trying to write a script that actually hooks people in the first 3 seconds, then double-checking every fact before I published it.
So I packaged the exact method I use for every single video on my channel: give it a topic and your source material, and it gives you back 10 scored title options, a full script (900–1300 words) with the hook built in, a mandatory fact-check pass with a reproducible score, and 5 scored thumbnail-text concepts. It only uses facts from the source you give it — if something isn't in there, it flags it instead of making it up.
It's not open source (it runs as a paid skill on Capafy, $4/week) — but it's real, tested code, not a demo.
Would genuinely love to hear what you think, especially if you make videos yourself: what's the part of the script-to-thumbnail process that eats the most of your time? Happy to answer any questions below 🙏
