Documents: Your uploads go directly to Anthropic for analysis and are not stored on our servers — no database, no logs, no retention. Case state lives in this browser tab; closing it erases everything.
Voice input: If you click Speak below, your audio is transcribed by your browser's built-in speech service (Google in Chrome, Microsoft in Edge, Apple in Safari) — same flow as any voice search. We never see the audio; we only receive the transcribed text. Read-aloud (on the response page) runs entirely on your device.

Four agents in series. Trust spine end to end.
Each stage feeds the next. The verifier double-checks the draft against the actual statute before you see it; the harden loop attacks the result before you send it. You see every step.
Read
Vision model extracts authority, deadline, identifiers, key facts. Translates non-English letters to English on the side.
Draft & ground
Web-grounded analyze ranks every realistic response option. Web-grounded draft writes the letter in the source language and proper legal register.
Verify
Streaming verifier extracts every citation and checks each against legislation.gov.uk / eur-lex / gov.uk in real time. Auto-fix rewrites the broken ones.
Harden
A counterparty agent attacks. A researcher gathers public evidence. A reviser rewrites. The audit trail goes in the packet.
