Mobile Jev

jev-use is a macOS voice and text computer-use harness built on Jev. It reads the frontmost app's Accessibility tree rather than taking screenshots, sends the command, app and window names, visible targets, and recent actions to Jev, then selects and performs operations such as clicking, typing, pressing keys, scrolling, opening items, and arranging windows. After each operation it reads the Accessibility tree again and continues until the task is complete, blocked, or waiting; low-confidence or destructive actions stop for confirmation. The app supports hold-to-talk, typed commands, hands-free listening, and an optional “Hey Jev” wake phrase, with speech handled by Apple Speech. It requires macOS 14.2 or later and Xcode, has no external dependencies, and stores the TypeSafe API key in the macOS Keychain.

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.

JevRouter is a local-first agent capability router for models, subagents, skills, MCP tools, CLIs, and DSH plugins. It presents these capabilities as one candidate set and uses Jev for typed selection while enforcing availability, permissions, risk, and confirmation policies. It is decision-only by default and does not execute selected tools implicitly. The `route` operation answers one capability-selection question; `plan` selects capabilities for multiple steps using serial, batch, or decomposed strategies, with optional beam sequence search and contextual routing. Candidates can be supplied inline or discovered from Skill directories, MCP configurations, CLI help output, and DSH manifests. The router preserves Jev probabilities and provider responses, validates supplied permissions and input schemas, filters unavailable or disallowed candidates, and can select a safe fallback while retaining the original Jev choice. The CLI, Node.js SDK, HTTP server, and MCP adapter expose the routing contract. Decisions and plans are written as append-only receipts with provenance hashes, and a local dashboard reads those files without making provider requests or uploading data. It supports the official Jev API and OpenRouter, has an offline demo provider, requires Node.js 20 or later, and is distributed under the MIT license.

Mobile MCP is an open-source Model Context Protocol server from Mobile Next for automating and scraping native iOS and Android applications on simulators, emulators, and connected real devices. It exposes a platform-agnostic set of MCP tools for device management, app installation and control, taps, swipes, text input, screenshots, screen recording, device logs, crash reports, deep links, orientation, location, and clipboard operations. The server primarily drives applications through native accessibility trees and structured UI-element data, falling back to screenshots and coordinate-based actions when required. It can run locally over stdio or as a Streamable HTTP server, and can use Mobile Next Cloud to reserve remote physical devices through the same tool interface. It is distributed as the `@mobilenext/mobile-mcp` npm package and requires platform tooling such as Xcode command-line tools or the Android SDK for device access.

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.
