Project overview
About AI Tools History Archive
A public, source-linked registry for tracking how AI tools, services, products, APIs, models, and features change over time.
What the archive covers
The archive records material lifecycle events such as shutdowns, acquisitions, mergers, rebrands, API deprecations, API removals, model retirements, feature removals, pricing-model changes, and other major transitions affecting availability, ownership, identity, or access.
How a record is structured
Each entity can include a current-state summary, dated lifecycle events, public evidence links, confidence labels, review dates, known unknowns, related records, and a public correction path.
Why this archive exists
AI products change quickly, while original product pages, support notices, model names, and API documentation may later disappear or be rewritten. The archive keeps those transitions organized by entity, date, event, and evidence.
What this site is not
This is not an AI tool ranking site, recommendation directory, popularity chart, review platform, or automated verdict engine. It does not assign success, failure, safety, or blame without directly supporting public evidence.
Evidence and neutrality
Official announcements, documentation, support pages, changelogs, archived pages, acquisition statements, and regulator or court records are preferred. Secondary reporting is used when primary material is unavailable. Uncertainty remains visible when the public record is incomplete.
Current stage
Coverage is still incomplete. Records may be expanded, corrected, split, merged, or reclassified as stronger public evidence becomes available. The methodology and correction process are public so changes can be reviewed consistently.
