FAQ
Honest answers.
How are valuations calculated?+
Claude (Anthropic's LLM) searches live market data — Bring a Trailer, Cars & Bids, Classic.com, Hemmings, PCarmarket, and Hagerty Valuation Tools — and returns an estimate with 3–5 cited sold comps. Confidence score and reasoning are visible. Manual override is one click away.
What if I have a 1-of-1 car or restomod?+
Edge cases get a low-confidence flag and clear "needs another look" prompt. Your manual valuation is always respected — the AI is a tool, not the boss.
Is my data private?+
All documents are encrypted at rest in Supabase Storage. Auth via Supabase with optional 2FA. We never share or sell collector data.
What about state-specific rules?+
V1 ships with text-only reminders that you enter manually for inspection / smog. Auto-detection by state is coming.
Can I share access with my accountant?+
Today, sharing is by credential. Role-based read-only access for accountants and insurance agents is on the roadmap.
