This is one of several Jev listings for the same project. The canonical entry is Awesome Jev — yibie.
About this project
Public projects that use Jev, TypeSafe AI's System One model. Unofficial. Not affiliated with TypeSafe AI. Jev does not chat, write code, or see images. It returns Choice, Score, or Noul answers with probabilities. Your code decides what happens next. Official docs, skill, and launch demos (4) Related open reproductions sit in Related, not TypeSafe Jev. They are not Jev use cases. Unbuilt ideas are in docs/ideas.md, not in the catalog count.
Quoted from the project's README. Read the full README.

Highlights
- Each entry carries a code-inspected or demo-inspected tag, and the counts in the README come from a data/use-cases.json catalog.
- Sections separate action-taking projects from routing, MCP bridges, official SDKs and cookbooks, plus a set of reproductions that are not Jev use cases.
- Unbuilt ideas live in docs/ideas.md and are deliberately kept out of the catalog count.
- Unofficial and not affiliated with TypeSafe AI, published under CC BY 4.0.
Watch out
This is a link catalog, so it tells you what exists rather than whether a project still runs. Most entries are one line taken from the project's own README, and the code-inspected and demo-inspected tags record how far that check went, not a pass or fail. Related open reproductions are split into their own section because they are not Jev use cases, and the list is unaffiliated with TypeSafe AI. Copy reviewed against the repository README on 2026-10-04, not from running it.
Questions about this entry
Short answers drawn from the linked project or page.
Every entry is tagged code-inspected or demo-inspected, which records how far the inspection went rather than a verdict. The README counts are generated from data/use-cases.json and the method is written up in docs/research-method.md. If you need to know whether a given project still runs, you have to run it yourself.
No. Most of the catalog is primary projects that call the API: a browser agent that picks the next operation and target from an indexed DOM, a PostgreSQL helper that filters and classifies rows, a gateway that judges requests before they reach a backend, and a reranker for recalled memories. Other curated lists are collected in one section near the end.
Yes. Official cookbooks and patterns, official SDKs and adapter, and official docs and launch demos each get their own section, alongside sections for platform integrations, community clients and installable agent skills. Related open reproductions are split out because they are not Jev use cases.
Anything where a typed question is answered with probabilities and surrounding code acts on them: choosing browser or UI actions, picking emulator macros from RAM rather than screenshots, walking a graph to the next relationship, ranking shell history completions, judging a dependency diff, or turning a judgment into a Unix exit code. The README states plainly that Jev does not chat, write code or see images.
128 entries in sections: 58 action-taking projects, 7 model and skill routing, 2 email and inbox routing, 6 MCP and agent bridges, 4 official cookbooks and patterns, 3 official SDKs and adapter, 4 official docs, skill and launch demos, 7 platform integrations, 8 community clients, 9 installable agent skills, 12 other awesome-Jev lists, and 8 related-but-not-TypeSafe-Jev projects.
Yes. Eight entries sit in a Related, not TypeSafe Jev section and are explicitly not Jev use cases; the README says related open reproductions belong there rather than in the catalog of projects that use Jev.
Into docs/ideas.md, not into the catalog. The README says unbuilt ideas are kept separate and do not count toward the 128-entry total.

The typed-answer shape removes a category of data risk, not all of it. Zero data retention per surface, the legal set to read, and the controls that remain yours to run.
