I built a tier list that re-rates 245+ AI tools every week — the automation behind it

AI tool reviews rot faster than anyone can rewrite them. A tool that was S-tier in March ships a broken pricing change in June, a "top 10" listicle from last year recommends products that no longer exist, and every directory slowly turns into a graveyard of dead links.

I run AI Tier List, a bilingual (EN/KO) directory that ranks 245+ AI tools from S to D. My answer to review rot: don't re-review by hand. Make a pipeline re-rate everything weekly, and let humans only approve or reject.

The architecture

Everything runs on one weekly GitHub Actions cron (Next.js 16 + Prisma + Neon Postgres + Vercel):
