Unlock five additional Pro tools: Bornhuetter-Ferguson, interpretive diagnostics, sensitivity ranking, tail extrapolation, and one-call method comparison. $29 perpetual, one machine, no renewal.
Each of these is a real tool Claude will pick automatically when the conversation calls for it. No new prompting to learn.
Mack tests with verdict labels — "strong evidence", "significant", "borderline", "no evidence" — plus plain-English summaries and a recommended action for each finding. The result Claude can read back without further interpretation.
Drop each link ratio one-at-a-time and rank the cells by IBNR impact. Finds the few observations driving the projection in one call instead of dozens of trial-and-error excludes.
Fits exponential decay and inverse-power models to the late development factors, picks the better R², and reports the implied tail factor to plug back into compute_chain_ladder.
Classic BF projection with your a-priori ultimates. Returns BF + chain-ladder ultimates side-by-side so you see where the two methods agree and where they diverge — the canonical "second opinion".
One call that runs both chain-ladder and BF, reports per-AY differences, identifies the largest divergence, and gives a plain-English read on whether CL is being aggressive or conservative.
Free to call — inspect license state any time. Returns active/inactive, registered owner, expiry date, and a human-readable message. Useful for troubleshooting after installation.
Everything below ships free of charge to anyone who buys Pro today — that's the deal, one $29 unlocks all future Pro tools.
One price. One purchase. Lifetime updates within the v1.x line.
No. Chain Ladder is a calculation tool. Selection of data, factors, tails, exclusions, and the interpretation of stochastic error measures require professional actuarial judgement. The Pro tools give you better analytics and better summaries, not better advice — the judgement call still belongs to you.
Nothing leaves your machine. The MCP server makes no network calls, and the license file is verified locally with an embedded public key. See the privacy policy for specifics.
Each license is intended for one machine. We don't lock you in — if you bought one license and use it on your laptop and a server, we won't kick down your door. But if you're rolling it out across a 20-person team, please buy 20 licenses (it directly funds the next Pro tools).
If Pro doesn't do what you need within 30 days of purchase, email support@chainladder.app and we'll refund in full. No questions, no forms, just a same-week refund.
We may raise prices as more Pro tools land. Whatever price you pay today, that's the price — you're locked in for all v1.x updates and you'll never get a "renew or lose access" email.
Not yet. If you'd buy a $299 site license for an unlimited-seat firm bundle, email and tell us — that's how we'll know to build it.
