About this demo

Original JevFlow concept art · not gameplay.

Jev selects bounded actions from structured game observations; Mineflayer executes them. The project documents prepared scenarios and control limits. This cover is an original AI-generated illustration, not a recording of the bot.

About this demo

Browser Use · original project recording.

The published demo searches Google Flights from Zürich to London. It stops at results, without booking. Its reported timing describes this particular run, not a universal speed benchmark.

About this demo

Nader Dabit · project screenshot.

Sift evaluates message intent, then labels and filters the inbox. The project demonstration uses 500 synthetic emails and includes a keyword-rule comparison. It is not a connected Gmail session on JevFlow.

A column header with superpowers.

Type “Urgency” or “Ready to buy?” and let the rows fill themselves. Your spreadsheet gets the hint.

About this demo

Nader Dabit · project screenshot.

A standalone spreadsheet demo interprets the column header and uses Jev to evaluate each row. It is not an official Google Sheets integration. The grid supports reviewing and undoing predicted columns.

SQL, meet a little common sense.

Ask your tables for “customers about to cancel.” Filter and rank rows by what they actually mean.

About this demo

JevFlow illustrative query · example data.

The PostgreSQL extension evaluates rows through the Jev API. Ordinary SQL handles exact filters and aggregation. Row data is sent to the provider; this is not an offline index. The preview uses fictional data.

About this demo

JevFlow illustrative preview · not a benchmark.

This Claude Code plugin uses Jev decisions to keep, truncate, or remove tool calls and results. Kept content remains verbatim, but relevance decisions can be wrong. The preview is illustrative and does not measure compression quality.

A DIFFERENT KIND OF AI

The next move.
Without the monologue.

A Jev AI agent puts quick decisions to work. Jev picks, scores, and sorts. Code takes action. Other models step in when the job needs planning or words.

A few things
worth knowing.

The useful bits, minus the jargon.

What is a Jev AI agent?

An agent that uses TypeSafe’s Jev model to make decisions during a task: choosing an action, evaluating an item, or routing work. Tools execute the actions; another language model can handle planning and writing.

Can I run these agents here?

Right now, you can explore the community demos and visit their original projects. Try takes you to JevFlow’s early-access page for the experience you picked. Hosted agents are not available here yet.

Does Jev write text or see screenshots?

Jev returns structured choices, scores, and truth probabilities from text-based state. In these projects, surrounding tools handle browser observations, game state, and execution. Other models can handle text generation.

Are these official Jev projects?

JevFlow is independent. These projects were built by community developers, with author and source links on every card. Jev itself is made by TypeSafe.

Is every decision correct?

No. A structured answer can still be wrong. Good agent workflows validate actions, check outcomes, and send uncertain cases for review. A compelling demo is not a reliability guarantee.

Where can I find the API and pricing?

For current model access, documentation, and pricing, visit TypeSafe’s official website. Running a full agent may also involve browser, hosting, and other model costs. Visit TypeSafe ↗
