The Model Atlas

The Model Atlas is an independent directory of AI tools and model websites that offer a documented way to start at no cost. It is aimed at people choosing an AI service for chat, research, images, video, audio, coding, writing or productivity who want to know what is free, and what needs an account, before signing up anywhere.

The directory covers 218 services in eight categories. Each listing summarizes what the tool does and records the type of free access (free plan, free access, public demo or free credits), whether an account is required, links to the official sources used and the date the entry was checked. Search and filters run in the browser, and the list can be narrowed to free plans or to tools that need no account.

Entries come from reviewing provider documentation and public product pages rather than testing every feature with a signed-in account, and the site treats provider pages as the final authority on limits. The order of listings is editorial and is not a quality score, endorsement or model leaderboard. Browsing requires no account, and the site has no payment forms or newsletter sign-up.
