Timbre (usetimbre.ai) is a voice-preserving technical writing assistant that protects a founder's authentic voice while maintaining absolute fact-fidelity. The system runs an automated check loop: it parses context into a verified claims ledger, drafts rewrites matching style/Voice DNA, and uses Antigravity SDK-level post-tool audit filters to verify the rewrite back against the ledger. This catches and auto-corrects factual drift or "AI slop" before content is published.
