ldraw-nova
362GitHub stars
Agent tooling that turns a model idea into a buildable LEGO model: the agent writes a plan and a generator script that produce LDraw source, plus a 3D viewer, a Blender-editable glTF file and a Meta Quest 3 VR view. Part search uses jev-rerank, a semantic search reranked by TypeSafe's Jev.
Jev Tools & CLIs#community#catalog-import#madewithjev
Communityanteloc/ldraw-novaPython
Instructor for PHP
328GitHub stars
A PHP monorepo that adds typed decision APIs on top of structured output, unified inference, retrieval and an agent SDK: the Polyglot Decision API can call the TypeSafe provider and return probabilities for noul questions, alongside OpenAI, Anthropic, Gemini and Ollama drivers.
Jev Repos & SDKs#community#catalog-import#logicrw
Communitycognesy/instructor-phpPHP
OrchestKit
296GitHub stars
A free, open-source Claude Code plugin that adds skills, agents and hooks for review, testing, security and memory: install ork for the stable v9.x line or ork-alpha for v10, which ships daily, then run /ork:setup to scan your repo and recommend skills.
Jev Agents & MCP#community#catalog-import#logicrw
Communityyonatangross/orchestkitTypeScript
pi-fabric
292GitHub stars
A programmable runtime that gives the Pi coding agent one fabric_exec tool: Pi writes a checked TypeScript program that composes core tools, MCP servers and agents into branches and fan-out, executed in an isolated QuickJS sandbox with approvals, budgets and durable coordination.

Communitymonotykamary/pi-fabricTypeScript
JevPilot
224GitHub stars

Communitystandardagents/jevpilotJavaScript
OpenWhisper
211GitHub stars
A desktop app for dictation, audio-file transcription and meeting notes on Windows, macOS and Linux, using local Whisper models or the OpenAI API, with an opt-in MCP server and local history API so agents can search saved transcripts.
Jev Tools & CLIs#community#catalog-import#logicrw
Communityknuckles92/openwhisperPython
Interlinked CLI
180GitHub stars
A local guard layer for AI coding agents: it evaluates delivered tool hooks against deterministic rules, blocks dangerous ones in milliseconds with no model in the decision path, and keeps a grep-able local activity log for auditing.
Jev Tools & CLIs#community#catalog-import#logicrw
Communityquentincody/interlinked-cliTypeScript
runline
166GitHub stars
Code mode for agents: install a plugin, write JavaScript, call actions. Any API or host capability becomes a callable action, and agent code runs in a QuickJS WASM runtime where each configured plugin is a top-level global; 204 plugins ship bundled.
Jev Tools & CLIs#community#catalog-import#logicrw
Communitymichaelliv/runlineTypeScript
Yielded Agent
164GitHub stars
A TypeScript agent harness toolkit built on Effect and Effect AI: define schemas, instructions and tools, and the runtime runs the model/tool loop, validates output, and retains accepted work across process restarts using SQLite, PostgreSQL or Cloudflare hosts.

Nate Berkopec's dotfiles
151GitHub stars
Nate Berkopec's personal dotfiles converge a fresh macOS or Ubuntu host with one ./bin/dotf run command — Homebrew, mise, system packages, macOS defaults and Ruby steps — and the madewithjev listing credits the repo with a You Should Know plugin for Pi built on Jev and Luna.

大声读 (ReadAloud)
144GitHub stars
An English reading tutor for Chinese learners: R2T2 streaming ASR transcribes as you read aloud with a 160 ms step and committed text that only grows, then Jev answers closed questions per mismatched word — same word or not, error category, sentence score.
Jev Tools & CLIs#community#catalog-import#madewithjev
Communitywquguru/dashengJavaScript
Taskuary
140GitHub stars
A local, open-source personal AI assistant for your job: mail, chats and tickets become tasks, agents you already use such as Claude Code, Codex and Gemini do the work, and nothing is sent until you approve. The current release is v0.3.8.3.

Communityldbumble/taskuaryPython
LLM Chess
137GitHub stars
A Python benchmark that evaluates LLMs' reasoning and instruction-following by making them play chess against a random player or the Komodo Dragon engine in multi-turn dialogs, separating chess skill from protocol durability.

How entries are chosen

Every entry is reviewed against the same bar, whether it comes from TypeSafe or the community.

  • Public and working — no paywalls, sign-up walls, or dead links.
  • Concrete — it has to be about Jev and the System One API, not generic LLM content.
  • Useful today — something a developer can learn from or use right now.
  • Distinct — if a similar entry exists, the description has to say what makes this one different: a different runtime, a cheaper path, a measured result, or a narrower focus.
  • Documented — repos state their license, and docs are in English or carry an English summary.

Spam, affiliate links, and thin AI-generated content are rejected. New entries are expected to ship with a deep dive: two to five highlights, caveats, a quickstart snippet where one helps, and a verification date. Star counts are refreshed when an entry is touched.

Common questions

Short answers about Jev and how this directory works.

What is the Jev AI model?

Jev is TypeSafe AI's first System One model — an AI model that takes a state plus typed questions and returns one structured answer per question: a choice, an ordered score, or the probability of yes, with calibrated confidence on Choice and Score answers. Code can branch on the result without parsing generated text.

What is the difference between Choice, Score, and Noul?

They are the three question primitives. Choice picks one of up to 255 options, Score rates on 2 to 10 ordered levels, and Noul answers yes or no. Choice and Score answers carry a confidence between 0 and 1; a Noul answer is the probability of yes.

Which Jev SDKs and client libraries are available?

TypeSafe maintains official JavaScript/TypeScript and Python SDKs plus a Python adapter. The community has built clients for Go, .NET, PHP, Laravel, Rust, Elixir, Ruby, and Scala, along with framework integrations such as DSPy, LlamaIndex, and Home Assistant. All of them are listed in the Repos & SDKs category.

Is the directory free, and is it affiliated with TypeSafe AI?

The directory is free to browse: every entry is reviewed, and spam, affiliate links, and sign-up walls are rejected. JevDirectory.org is community-run and not affiliated with TypeSafe AI — Jev and System One are TypeSafe AI trademarks.

How often is the directory updated?

Entries are added as new resources appear and re-checked when they are touched. The directory currently holds 3919 entries from 293 source sites, last updated Nov 6, 2026.

What is a verified deep dive?

Most entries include a deep dive: two to five highlight bullets someone would only know from using the resource, a caveats note about limits and requirements, an optional quickstart snippet, and the date the link was last checked. 3919 of the 3919 entries carry one today.

For the canonical details, read the official TypeSafe docs and the API reference.
