AI Tools Index

512 real AI tools across 26 categories, ranked by popularity. Ranking is our editorial judgement of adoption and mindshare — tiers, not live download counts, and we say so rather than inventing precision. Tools with a Reviewed badge have a full HIMEXA review with scores and dated pricing.

Honesty notes: tiers are editorial, reviewed regularly, and never sold — no tool can pay to move up. Official links point at each vendor's own domain; products rename and merge often in this market, so if a link has gone stale, tell us. For scored, dated evaluations see the reviewed directory.
