Model changes that document themselves.
Model Lens is an AI layer for the Prophet model code your team already owns. It doesn't just draft the change — it produces the governance around it: the write-up, the code diff, the impact test, and the change report, ready for your actuary to sign.

You brief it in plain English. It produces the paper trail.
Load a workspace, describe the change you want, and for each one Model Lens returns four things — before you accept anything.
The documentation, written for you
The problem, what it means for the model, and the solution — drafted as you work, not reconstructed weeks later.
The exact before/after diff
The literal code difference for every change, so a reviewer sees precisely what moved and why.
Impact tested before you accept
A numeric test of the change on both your SAM and IFRS 17 bases — shown up front, so nothing lands unseen.
A compiled change report
Brief, review, changes, testing and a sign-off block — assembled into one pack, ready for your actuary.
The AI explains. It never does the maths.
→ Numbers are deterministic
Every figure is computed by a deterministic engine. The AI documents and explains the change; it never produces a number.
→ Nothing has to leave your boundary
Model Lens runs inside your environment — including on a fully local model, where no data crosses your perimeter at all.
→ Only the code your team authored
It works on your own model code — your libraries, your estate, your control. It reviews what you built; it doesn't reach into anything you licensed.
Blind-tested on a model built to fool it.
On a synthetic dual-basis model seeded with planted discrepancies and deliberate look-alikes, Model Lens caught every real issue and correctly cleared every intended difference — with no false alarms. Synthetic data, run blind against a hidden answer key. Your mileage on a real estate is exactly the conversation we want to have.
See it on your terms.
