identity.txt pitches portable AI identity across tools

identity.txt is an open, early-stage markdown convention for carrying a person’s voice, expertise, preferences, and usage terms between AI tools instead of rewriting custom instructions in each app. The project is published openly (CC BY 4.0) with a public spec and optional hosted profile URLs at identitytxt.org.

// ANALYSIS

This is a smart standards-first attempt at solving real prompt-fragmentation, but adoption by major AI platforms will decide whether it becomes infrastructure or just a niche format.

–It mirrors familiar web conventions (like robots.txt/llms.txt), which lowers the learning curve for developers.
–A portable profile could reduce repetitive setup across ChatGPT, Claude, Gemini, and future assistants.
–The “Terms” section introduces lightweight user-level governance, but enforcement is still voluntary.
–The open spec matters more than the hosted service, which gives it a better chance to survive platform shifts.
