System One AI Automations

JevCraft is an unofficial plugin for the Jev decision model by TypeSafe (typesafe.ai) — built by Lumostera, not affiliated with or endorsed by TypeSafe. Jev is a System One model that turns unstructured text into typed, probabilistic decisions in milliseconds, at about $0.04 per million input tokens. JevCraft also works with the same model hosted on OpenRouter (~typesafe/jev-latest). Fifteen decision nodes drop straight into your site's automation builder. Three building blocks cover any custom decision — a yes/no check, an option picker for routing, and a rating scale you define line by line. Twelve ready-made nodes handle common workflows: support triage, spam detection, lead qualification, review sentiment, intent routing, order prioritization, satisfaction scoring, churn risk, refund approval, question sorting, upsell spotting and content safety. Every node returns probability-backed outputs, so branches fire on confidence instead of guesses. Connect a TypeSafe or OpenRouter key once; keys live in your site's secret store and never leave your backend. A private decision history in your CMS makes every automated decision auditable — with zero external servers to maintain.
