jev-table-import-mapper
0GitHub stars
A dependency-free JavaScript library that maps uploaded CSV columns onto your destination schema: a strict normalized-name pass first, then one Jev boolean per remaining source-destination pair plus a guard question per column, leaving uncertain fields visible instead of guessed.
Jev Tools & CLIs#community#csv#data-import
CommunityDuvInc/jev-table-import-mapperJavaScript
tab-jev
5GitHub stars
A pre-release Python framework for predictions on mixed text and tabular data: Jev Noul and Score questions turn text columns into numeric features, then a tabular foundation model such as TabPFN learns from labeled rows in context. Offers hosted and fully local backends.

Jev Tools & CLIs#community#chrome-extension#ai-detection
Communityigloomatics/jev-ai-detectorJavaScript
LinkScout
0GitHub stars
A browser extension plus Cloudflare Worker that scores search results before you click: Jev answers six questions per page (relevance, depth, SEO filler, sales page, page type, key passage) and code combines them into a 0-100 badge that re-ranks Google, Bing, DuckDuckGo and 104.com.tw.
Jev Tools & CLIs#community#browser-extension#search
CommunityianTPE/linkscoutJavaScript
dsh-jev-interceptor
29GitHub stars
A DeepSeek Harness plugin where Jev Choice and Noul checks gate every non-read-only tool call - deny confident high-risk calls, escalate ambiguous ones, auto-approve clearly granted reversible ones - and optionally score session messages so valuable context survives instead of being dropped oldest-first.
Jev Tools & CLIs#community#plugin#guardrails
CommunityAskTheWay/dsh-jev-interceptorTypeScript
Ring Zero Security
11GitHub stars
Kernel-enforced runtime security for AI agents with eBPF/LSM: policy decides file, exec, package-install and MCP operations at the syscall, while Jev can run as an optional checks provider whose verdict can only raise severity. The Jev checks layer is off by default.
Jev Tools & CLIs#community#security#ebpf
Communityringzerosec/jev-runtime-securityRust
JIT-JEV Context OS
8GitHub stars
Epistemic runtime for autonomous coding agents that uses Jev as a sub-100ms System 1 gate to shadow-evaluate capsule facts, propose evictions before bloat and prefetch memory between turns. Its fixture run reports 31.3% fewer turns and 52.6% fewer blind discovery operations, with a fail-open circuit breaker.
Jev Integrations & Adapters#community#agents#context-engineering
Communitywojciechwiesner/jit-contextPython
DeepSearcher Jev stopping experiment
8.3kGitHub stars
Agentic search evaluation inside Zilliz DeepSearcher: a standalone harness replaces the ChainOfRAG reflection call with one Jev Noul per round to decide whether to stop within a seven-round budget, then compares stopping behavior, evidence recall and decision cost on 100 sampled 2WikiMultiHopQA queries.

Communityzilliztech/deep-searcherPython
OpenClaw Jev Trigger
1GitHub stars
OpenClaw plugin and CLI that turn a plain-language --when/--not-when condition into a scheduled trigger script. Each tick sends one Noul through OpenClaw's decisionModel and only wakes the conversation model when the condition reaches 0.7 or above; a 76-tick benchmark reports 75 correct judgments and 0 false wake-ups.
Jev Tools & CLIs#community#automation#openclaw
Communityyousan/openclaw-jev-triggerTypeScript
RSI-Jev
117GitHub stars
Open decision models from a self-improvement loop that publishes every experiment, failures included. They answer Noul, Choice and Score questions on the same POST /v1/systemone wire format as Jev, returning a calibrated probability per option in one forward pass; the 27B scores 65.64 on the Decision Index 0.3 set.

JEV Book Tags
0GitHub stars
Calibre plugin that asks Jev typed questions about each book's genre and subjects, applies configurable per-category probability thresholds, preserves existing tags and leaves uncertain results for manual review. Supports single-book, selected-books and whole-library classification with caching, CSV export and restore.
Jev Tools & CLIs#community#calibre#library
Communityiamjonatha/jev-book-tagsPython
jev-oncall
4GitHub stars
On-call tooling where Jev answers four typed questions per alert - actionable, severity, owning team and duplicate-of - and plain code routes, pages or drops. Includes a root-cause benchmark where Jev and code investigate recorded incidents with no general-purpose LLM in the loop, enforcing budgets and verification.
Jev Integrations & Adapters#community#alerting#incident-response
Communitymingleiw/jev-oncallHTML
sortwell
0GitHub stars
MCP server and Claude Code plugin that files each captured note, link or meeting line with one Jev request: kind, project, action and duplicate questions answered in parallel. Routes to a project only at 0.45 or above, marks a duplicate only at 0.70 with a matching item, and stores text verbatim in append-only JSONL.
Jev Agents & MCP#community#mcp#note-taking
Communitydharun-cohere/jev-sortwellTypeScript
jev-acento
0GitHub stars
Independent pre-registered audit of Jev on Spanish: 19,200 calls over 3,200 paired items on XNLI, PAWS-X, MASSIVE and Belebele. A Spanish state costs 3.0-6.4 accuracy points and roughly doubles ECE on the two hardest tasks, while Spanish instructions change nothing; a CLI reruns the same comparison on your own data.

Communityrun-llama/jev_vs_ossJupyter Notebook
kNES
34GitHub stars
Kotlin NES emulator whose agent plays Super Mario Bros. and Final Fantasy through typed decisions. Each turn becomes one Choice over goals that can actually run, wired through SemIf against a local Qwen3.5-4B, so a button the game does not offer is never an option; 900 logged decisions never answered off-menu.

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.
