Tools

• check_voice_match ~265 tokens
  Score any text (20+ words) against the guest profile by feature-delta measurement. Returns voice_match_score (0-1), the per-feature `deltas` behind it, notes rendered from them and score_context caveats. On-voice text typically scores 0.85-0.95; below 0.45 is clearly off voice. Cite the delta number
• claim_status ~183 tokens
  Whether the person has claimed the guest session yet: status (active, expired, archived or claimed), claimed, archived, expires_at and claim_url. Works after expiry too. Once claimed, the guest_token stops working; the profile is in the person's own account, reachable with their API key or https://m
• compare_voice ~408 tokens
  Off-voice check with no profile: score up to three pieces against a main piece. Each piece is pasted text (120+ words) or a public URL. Returns per-piece `score` (0-1: 0.8+ on voice, 0.55-0.8 drifting, below 0.55 off voice), `band`, `top_differences` and `top_matches` with the measured numbers, plus
• create_profile ~459 tokens
  Build the guest session's one voice profile from the person's own writing and start the stylometric extraction (45 measured attributes). Samples MUST be their own human-written prose. You can use writing you already hold for them (messages they typed to you, documents or emails they shared, posts of
• get_profile ~191 tokens
  The guest profile's status and detail. While extraction runs it returns progress_percent; once status is 'complete' it includes the narrative voice description and all 45 measured attributes. Poll every ~10 seconds after create_profile.
• start_session ~166 tokens
  Start a free guest session with no account. Returns guest_token (pass it to every other tool), claim_url (give it to the person: it keeps the voice profile in a free ScriptGrain account, or deletes it), expires_at and limits (one profile, one extraction, no drafts). Unclaimed sessions are archived a
