Common questions
- Does Threadmark change my tree?
- Never. Threadmark is read-only and does not connect to Ancestry or any other platform. It analyses a copy of your file and reports what it finds. Every change stays your decision, made in whichever software you already use.
- Why is the full analysis free?
- The analysis is what makes Threadmark useful, and hiding it behind a paywall would defeat the point. Free gives you the real score, every issue found, Fix Packs, full exports, and local re-scan comparison. Project Scan adds cross-device project history and its own AI Roadmap and Conflict Resolver allowances.
- Can I buy Project Scan today?
- Not yet. Checkout is still being built. The button captures your email so we can tell you when it is ready — it does not take payment and does not create an account.
- Is it a subscription?
- No. Project Scan is a single $19 payment that opens a 30-day window for one project. There is no recurring charge and nothing to cancel.
- Is the score produced by AI?
- No. The score comes from a deterministic rules engine — the same file always produces the same score. The optional AI tools help you plan and work through conflicts; they never change your score.
