Snapshot testing for AI behavior — catch regressions offline in CI
A live run captures every model request and response into a local SQLite cassette that CI can replay offline and deterministically at zero cost.
Point EvalCore at OpenAI-compatible endpoints, vLLM, Ollama, your own REST APIs, shell commands, or OTel/OpenInference traces — no SDK required.
Stack contains, judge-rubric and other scorers in YAML to express exactly what a correct answer looks like for each case.
Compare against a baseline branch so only real regressions fail, and let the process exit code gate your pull requests.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
