Try Leapter.
Create your first Blueprint — decision logic made visual and testable — in minutes.
AI helps you build it. No AI when it runs.
Two ways to start
Try it in your browser
The fastest way to see your own logic as a Blueprint.
- Describe your decision logic in natural language — or upload a policy document — and get a Blueprint in seconds.
- Verify the logic visually, or in the Spec view: text and Blueprint side by side.
- Make changes with AI assistance and see the impact immediately in Leapter’s live mode.
- Run your own tests, or use the AI-generated tests to catch errors at the source.
- Export the Blueprint and embed it in your workflow.
Connect it to Claude and build where you already work
Download the Leapter package, register it in Claude as an MCP server — MCP is the agent integration standard — and build Blueprints directly from your Claude environment.
- Build internal applications with Claude Code: Claude generates the app, Leapter holds the logic.
- The logic underneath is a Blueprint the business owns and approves — what you approve is what runs.
- Applications call the approved logic through a REST API, with a full trace for every execution.
How to install Leapter in Claude

Unzip it and follow the included README to register Leapter as an MCP server in Claude.
Open Claude and say hello. Leapter handles the rest.
What you can build in 10 minutes
Not a tour — a working result. These are first-session builds, each one a Blueprint you can test, trace, and change before the ten minutes are up.
A KYC screening Blueprint
Screen a customer and get back a risk rating, a decision, and a written explanation — with a trace showing exactly which checks fired and why. Change a threshold and re-run the same case to see the decision move.
A vehicle tax calculator
Give it a passenger car’s first registration, engine type, displacement, and emission data, and get the annual German vehicle tax — correct across every band, with test cases proving it before anything relies on the number.
A warranty coverage classifier
Feed it a product’s type, age, usage, and premium status and get a coverage decision you can defend — and change yourself when the policy changes, without opening code.
Each example produces a working Blueprint with testable logic and an execution trace you can inspect.
If it has rules, thresholds, and conditions, you can build it here: pricing rules, underwriting logic, discount engines, approval workflows, eligibility checks, compliance calculations, risk scoring, tax and fee computations.

Evaluating Leapter for a regulated team? The trial shows the mechanics; a briefing shows it on your own decision. Bring one example — a credit policy, an eligibility rule, a claims workflow — and we will walk it end to end with you.
