Timbre: Brand Voice Guard

Define your brand voice once. Timbre scores every draft against it — banned terms, off-brand phrasing, unsubstantiated claims — before it ships.

Brand voice dies by a thousand small drafts. Timbre keeps it alive: define your tone attributes, preferred and banned vocabulary, and claim rules once — then check any draft against them in seconds.

WHAT IT MEASURES A deterministic analyzer scores each draft across four weighted dimensions: lexicon alignment, claim integrity, readability, and tone match. Every issue is flagged in place — banned terms, unsubstantiated claims, hedging, passive voice, overlong sentences — with exact positions.

FIX IT FAST Read the flagged draft with highlights, or let a connected AI model rewrite it to match your voice — the rewrite is re-checked before you see it. Works with on-device Apple Intelligence, local Ollama / LM Studio, or your own cloud API key. The analyzer itself needs no model at all.

PRIVATE BY DESIGN No accounts, no analytics. Your voice profile stays on your Mac; keys stay in the Keychain.
