Trinity Local v1.7.396 — Ask all three. Keep what works.

Trinity Local is a free, local, cross-provider council + memory layer that lives inside Claude Code, Codex CLI, Antigravity, and Cursor. Send one prompt to Claude, ChatGPT, and Gemini in parallel; a chairman synthesizes the verdict — what they agreed on, where they split, which answer wins — on the subscriptions you already pay for. No API key. Your transcripts never leave your machine.

What's inside

• Cross-provider council — one prompt, three labs, one synthesized verdict, plus exactly where they disagree. Works day one.
• Your lens — builds quietly from the transcripts already on your disk (how you rephrase, judge, and decide); then every council runs through it and the chairman returns the answer you would have picked.
• Score any model against your taste — a per-axis number on your own hardest questions the day a new model lands. A benchmark no lab can publish.
• Local-first, no API key — an MCP server + a Chrome extension. The embedding model and index stay on your machine; only anonymous, opt-in categorical routing labels ever leave (never prompt content).
