AI tools you can use right now without paying a cent. Tested, ranked, organized by category. No trial, no paywall — really free.
Every tool on this list is actually usable on the free tier — not a 7-day trial that requires a credit card. We excluded tools that gate core features behind paywalls. Where there's a usage limit (e.g., "10 generations/day"), we noted it. These are the tools you can build a real workflow around, for $0.
