Launches on September 21, 2026

The Android assistant reads visible conversations through accessibility and local OCR, displaying analysis and reply suggestions in an overlay. Jev judges intent and response choices; a generative model drafts three candidates and Jev ranks them.

AnyJev reads probabilities from open models to answer choice, yes/no and scoring questions without generating prose. It is an independent Jev-style approach; its L2 heads leave the base model’s weights unchanged. Use label-free L0 readouts or fit an L2 head for a particular question, with transformers or vLLM.

Rizzo Flow runs open decision models locally, returning choices, probabilities, rubric scores and numbers through a Jev-compatible HTTP interface. It reproduces Jev’s interface pattern, not its proprietary architecture or training; the project is independent. Serve a selected model with llama.cpp and point TypeSafe-compatible application code at the local endpoint.

JevChat-Windows reads WeChat and KakaoTalk conversations with local OCR and offers candidate replies beside the chat window. Jev judges intent and tension and ranks three candidates; a separate language model drafts them. Configure a decision-provider key and a drafting-provider key on Windows 10 1903+ or Windows 11.

The floating chat panel displays intent and risk judgments and candidate replies that users can copy or insert into the chat input. Use an Apple Silicon Mac with macOS 13 or newer. Grant Screen Recording for screenshot-based reading and Accessibility for text access or insertion, then choose judgment and generation providers in settings.

JevHarness lets a language model write task-specific features, questions and control logic, with optional improvement from rewards and complete traces. Explore the archived Pokémon run locally with the website scripts, or install the skill and describe a task to build a harness.

A candidate-scoring head returns distributions for gates, routes and scores without decoding prose or JSON answers. The README compares a benchmark-trained AgentJev specialist with Jev 1.13.0 evaluated zero-shot; these use different training conditions.

Run Jev-style typed decisions locally on your Mac with low RAM usage and fast responses

Software, by reflex. Say it, and the right small program runs: chosen by a calibrated classifier, run only when it is sure enough, and it asks before anything that cannot be undone. A CLI, a package manager and a TypeScript SDK: the first implementation of the idea.

A Minesweeper benchmark for LLM agents. One identical board, up to nine models in parallel, one clock, one tool layer.

Semantic "Did you mean?" for any CLI — wraps commands and uses TypeSafe's Jev to match subcommand typos by intent, not edit distance.

A local, offline System One server compatible with TypeSafe's Jev API. It answers typed yes/no, category and score questions with small open models.

jev_elixir is a small, idiomatic interface for making typed decisions with Jev. It exposes application-level functions such as Jev.ask?/2 and Jev.analyze/3, while provider adapters handle the external API wire format. The first release supports TypeSafe's System One API and OpenRouter's Decisions API. Both providers support all three System One qu
