# Awesome Jev [](https://awesome.re) [Jev](https://docs.typesafe.ai) is TypeSafe's System One model for probability-based yes/no judgments, choices, and scores rather than generated text. Check permissions and data handling before running a project. Source review is not a runtime test or a security audit. ## Contents - [Getting Started](#getting-started) - [Demos](#demos) - [SDKs and Skills](#sdks-and-skills) - [Browser and Desktop Tools](#browser-and-desktop-tools) - [Agent Tools](#agent-tools) - [Apps and Integrations](#apps-and-integrations) - [Games and Creative Projects](#games-and-creative-projects) - [Independent Models](#independent-models) - [Reading and Research](#reading-and-research) - [Supporting Drivers](#supporting-drivers) ## Getting Started Start with the [quick-start example](docs/DIRECTORY.md#20-second-quick-start), then build a [typed classifier](docs/START_HERE.md#build-your-first-typed-classifier), use Jev in an [agent](docs/START_HERE.md#use-jev-in-an-agent), or explore a [local alternative](docs/START_HERE.md#explore-a-local-alternative). The [source notes](docs/REVIEWED.md) record setup, privacy, and evidence limits for the selections below. ## Demos A few examples to watch before digging into the code. These are creator recordings and publisher previews, not independent benchmarks. Linked previews open the original recording or post. <!-- demo:ultrafast --> - [Jev Ultrafast](https://github.com/browser-use/jev-ultrafast/blob/main/README.md) - A flight-search recording where Jev chooses browser actions and elements; a separate model writes field text.
