Leapter launches ChatGPT plug-in for visual business rules

Leapter has launched a ChatGPT plug-in that lets business experts draft rules in plain language and test them in Leapter’s visual decision engine. The tool is designed to make automated decisions easier to understand, review and audit.

Why it matters: - Business rules often live inside code, which makes them hard for nontechnical teams to inspect. - Leapter’s new plug-in is meant to give subject-matter experts a direct way to create, test and explain decision logic before it goes live. - The approach could reduce errors in pricing, eligibility and approval workflows where exceptions matter.

What happened: - Leapter introduced a new ChatGPT plug-in on November 9, 2026. - The plug-in lets business experts describe a rule in their own words and turn that description into a visual, executable diagram. - Users can save the draft in Leapter Lab and continue refining the rule there. - The release was announced from Weimar, Germany.

The details: - Leapter presents conditions, calculations and exceptions in an executable diagram called a Blueprint. - The same logic that teams review in the Blueprint is the logic that runs in production. - A pricing team can use the system to trace why one offer received a discount and another did not. - Recorded executions show the inputs, the outcome and the rule version used. - Teams can walk through the prior decision path step by step in the Blueprint. - Teams can also test how a new threshold would affect typical cases and edge cases before changing the rule. - Leapter uses AI to help with rule creation. - Execution remains deterministic. - The same rule version produces the same result when inputs are the same. - Applications and AI agents can call the stored logic. - The version history shows who changed a rule and when. - Review and approval workflows record comments, decisions and sign-offs. - Those records are available for later audits.

Between the lines: - Leapter is positioning the product around trust, traceability and compliance, not just speed. - The plug-in fits a wider push to let business teams work with AI while keeping final execution deterministic and auditable. - The company is also trying to bridge the gap between natural-language drafting and governed enterprise automation.

What's next: - Leapter says teams can try the plug-in in ChatGPT now. - The company will likely use the launch to broaden adoption of its Blueprint-based workflow among business and operations teams. - Leapter is also expanding its investor base, after announcing a 2 million euro pre-seed round in July 2025.

The bottom line: - Leapter wants business experts to design automated decisions in ChatGPT, then test and audit the same logic inside a governed execution layer.
