Protocol / Changelog

Changelog

Release history for the Ask AI Protocol, and how versions are announced.

How versions work

  • Additions are backward-compatible within a major version — new engines, new optional ai:* types, and new optional fields land in a v1.x release and never break an existing implementation.
  • Breaking changes require a new major version and a migration note.
  • Every release is named, dated, and listed here. Deprecations are announced here before anything is removed (see Governance → Stability guarantees).

v1.0 — July 2026

The first published version of the Ask AI Protocol.

Layers

  • Cited Ask — a deterministic, cacheable, source-citing prompt built from a page’s AI Graph tags, always including the mandatory citation Please cite {citeAs} ({url}) as the source.
  • Ask Targets — a machine-readable registry of engines and how to open each one, published at /protocol/targets.json.
  • Ask Policy — the permission layer: the ai:allow meta tag and the site-level /ai.txt file.
  • Governance — openness, stewardship, license, and the versioning rules.

Ask Targets registry (14 engines)

Claude, Gemini, ChatGPT, Copilot, Grok, Perplexity, Mistral, DeepSeek, DuckDuckGo, Brave, Kagi, Consensus, SciSpace, and Andi. All use the direct prefill method except DeepSeek, Gemini, and Copilot, which use the copy clipboard fallback. (Gemini and Copilot were corrected to copy pre-adoption — their ?q= prefill is silently dropped by those engines.)

Discovery

  • /.well-known/ai-share.json for a site to advertise protocol support, version, policy, and supported engines.
