jev-use

jev-voice-browser is a Node application that controls a headed Chromium browser by voice or typed commands. It streams partial speech transcripts from the browser's Web Speech API to a Node server, which uses TypeSafe's Jev model to classify the intent, select a page element or site, extract candidate text and URL spans, determine whether the command is complete or addressed to the browser, and assess whether an action is destructive. Playwright then executes navigation, searches, typing, clicking, scrolling, history, and tab actions. The application sends the page URL, title, detected site, a compact snapshot of visible elements, and recent actions to Jev for each transcript update. Code—not the model—constructs URLs, copies text verbatim, and applies policy thresholds to decide whether to act, wait, ignore, request confirmation, or show numbered alternatives. Recent action context supports corrections such as reversing an action, rejecting a selected result, or choosing another candidate. It requires Node.js, Chrome or Edge for microphone input, Playwright's Chromium installation, and a TypeSafe API key. The server can launch a persistent-profile Chromium window or attach to an existing browser through CDP; it also supports headless operation and typed commands when no microphone is available.

Jevry is an open-source, MIT-licensed desktop browser agent created by Michael Swissa. It is an Electron browser that combines a language model for planning and text or visual reasoning with TypeSafe's Jev model for selecting typed actions from controls observed on the current page. Chromium executes the selected operations through guarded native input rather than generated JavaScript, arbitrary selectors, or shell commands. Its loop observes page text and compatible controls, compiles supported operation-and-target choices such as clicking, typing, scrolling, or stopping, asks Jev to choose, validates the choice against the current document and target, executes it, records an input receipt, and checks the resulting evidence before continuing. It supports browser tasks such as forms, page-grounded questions, research and citation, documentation navigation, catalogs, and selected visual or numeric games. The project is an experimental developer preview for macOS and Windows; it requires a TypeSafe Jev connection plus a text-model connection, and some capabilities—including uploads, extensions, password-manager workflows, and certain cross-origin interactions—remain unsupported or unverified.

Mobile Jev is a standalone Android agent from droidrun that turns a written goal into device actions through the Mobilerun API, using TypeSafe's Jev to choose operations such as opening apps, tapping, entering text, scrolling, navigating, waiting, completing, or blocking. It observes the device, offers indexed controls and installed apps to Jev, validates the selected target against fresh screen data, executes the action, and observes the device again; it does not require an ADB connection. The executor resolves coordinates from observed bounds, rejects stale targets, records actions and execution traces, and verifies field values after text entry rather than relying solely on a model completion response. The project includes a local React studio with a live device stream, goal input, action timeline, task clock, model-latency measurements, stop and reconnect controls, and recent runs, along with a CLI for previewing or executing goals, inspecting devices, taking screenshots, profiling API timings, and issuing direct controls. It requires Node.js, pnpm, a Mobilerun Android device, and Mobilerun and TypeSafe API keys; it is intended for a single local operator, with recent runs held in memory. The repository is MIT licensed.

typesafe-computer-use is an open-source macOS computer-use tool that drives a Mac toward a plain-English goal. It captures the frontmost window, reads text with OCR, collects labelled controls from the macOS accessibility tree, parses dates, and sends a structured list of possible actions to the TypeSafe decision model instead of sending screenshots to a frontier model for every step. The loop chooses actions such as clicking, scrolling, browser navigation, waiting, or pressing keys; a writing model is called only for free-text entry, proposed URLs, and the final answer, while passwords are never typed. It supports dry runs, confidence and step limits, annotated captures, detailed action and probability logs, and offline replay of saved screenshots. The repository targets macOS 14 or newer with Python 3.12 or newer, requires a TypeSafe API key, and is licensed under the MIT License.

Jevgrep is a command-line tool for coding agents that finds relevant files and source context in unfamiliar repositories from natural-language questions. It uses Jev to judge relevance across folders, files, and declarations, explores qualifying branches of the repository hierarchy, selects files through content previews, identifies useful source units and surrounding context, and returns a summary followed by file locations, reading leads, and verbatim excerpts with line references. Python and TypeScript/JavaScript support declaration parsing, while other text uses a fallback. It also includes an agent skill that teaches supported coding agents when to invoke the CLI and how to use its results. The CLI is distributed through npm as @dzhng/jevgrep, requires Node.js 22 or later on macOS or Linux, and requires authentication with a supported AI provider. Searches send eligible source content to Jev through the selected provider; local filtering excludes ignored, hidden, dependency/build, binary, and obvious credential files but is not a guarantee that sensitive data is removed. The project is MIT-licensed.
