LLM Change Detection & Rollback
A developer tool that continuously regression-tests your LLM workflows against a reproducible suite of prompts, tool calls, and structured outputs, and alerts you when behavior drifts beyond tolerances. It produces diff reports (semantic + schema-level), gates deployments in CI, and provides practical mitigations (prompt patch suggestions, routing rules, fallback models, or local model baselines) without requiring you to build an in-house eval platform.

LLM Change Detection & Rollback
A developer tool that continuously regression-tests your LLM workflows against a reproducible suite of prompts, tool calls, and structured outputs, and alerts you when behavior drifts beyond tolerances. It produces diff reports (semantic + schema-level), gates deployments in CI, and provides practical mitigations (prompt patch suggestions, routing rules, fallback models, or local model baselines) without requiring you to build an in-house eval platform.
Target customer
Solo operators and small dev teams (agencies-of-one, internal tools engineers, SaaS teams) who ship production LLM workflows to clients and need stability guarantees and fast incident response.
Problem-solution fit
Customers are currently absorbing the cost of platform churn as unplanned maintenance and client support when outputs subtly change. This product turns vague “it feels different” issues into measurable contracts (expected JSON schema, rubric scores, tool-call sequences), detects drift quickly, and provides rollback/routing controls so teams can keep SLAs and reduce firefighting.
