Browser & computer use — built on Jev
Web and desktop agents click many times per task, so per-step cost and latency dominate. Projects here use Jev to pick a target from a candidate list, flag blocking overlays, or choose the next screen action — keeping each step typed and cheap.
The pattern that appears most often: summarize candidates into state, constrain the answer to your own element IDs, and let deterministic code perform the click.
Jev Ultrafast
Browser Use's ultrafast agent: Jev picks the operation and DOM element in one request; a small LLM only writes text when typing is needed.
typesafe-computer-use
Computer use for about $0.0002 a step: OCR the screen, classify the next action with TypeSafe, click. macOS.
unclutter
WXT browser extension: Jev-powered page clutter removal with reusable template rules.
mobile-jev
Standalone Android agent for Mobilerun where Jev makes every decision, with a live React studio and an Uber demo.
jev-browser-use
5–10x faster browser operations: Jev clicks, Codex thinks and verifies. Built at EZCollegeApp.
jev-browser
Browser use using Typesafe's Jev model.
jev-voice-browser
Control a real browser by voice. Jev (TypeSafe System One) decides intent + target in ~300 ms per spoken word; Playwright acts — often before you finish the sentence.
typesafe-adblock
🧹 Fun project: a Chrome extension that asks a tiny AI decision model (TypeSafe Jev) "is this DOM element an ad?" and pops it off the page. BYOK, no backend, not a real ad blocker.
vibecheck
Chrome extension: vibe-check your X posts with TypeSafe's Jev before you hit Post.
Jevbridge
ACP and MCP adapter that bridges TypeSafe Jev with any LLM — computer use and typed decisions alongside Codex, Claude, Grok, and OpenCode.
jev-reviewer
Data extraction for systematic reviews, quoted from the papers. Ask a trial report and its supplements your extraction form or a RoB 2, ROBINS-I, QUADAS-2 or TIDieR template; Jev points at the lines, every answer is a verbatim quote with its page, you check it and export the table. Files stay in your browser.
jev-browser (Ying-Kai-Liao)
Browser automation where an LLM plans and Jev (Typesafe System One) decides. Library, CLI and MCP server.
jot
The first general-purpose System One agent for Jev.
live-jev
2D autonomous car simulation in the browser, driven by TypeSafe's Jev decision model.
x-scanner
Chrome extension that labels every post you scroll past on X with typed Jev judgments and a live cost counter.
xtags
在 X 的时间线上，给每条帖子标出它想让你干什么。判断来自 Jev，一个只返回概率、不生成文本的模型。
jev-social
Jev-powered social media research through the socai CLI.
jev-ego
TypeScript browser agent for ego lite: Jev Ultrafast indexed actions, TypeSafe Jev decisions, persistent observe/act CLI. No Chrome or Playwright.
sift (bohutang)
Chrome extension that labels every post on X (Substance · Humor · Chit-chat · Promo · Junk · AI-written) with TypeSafe Jev, and hides the ones you don't want.
AskJev
AskJev — Jev autopilot for any website + guard on irreversible clicks (TypeSafe System One, not Claude).
jev-block-android-ad
JevNoiseGate filters unwanted notifications and SMS on Android. Rather than matching keywords, an LLM decides what's noise — and only what it explicitly flags is blocked. Verification codes are matched on-device and never uploaded; anything uncertain passes through.
jev-browse
Drives a real browser with Jev making every decision and Vercel's agent-browser performing every action, with a benchmark.
jev-browse (0x7067)
Browser automation with Jev (TypeSafe) as decision model.
jev-browser (vinilana)
Hybrid browser harness: an LLM turns goals into verifiable subgoals, Jev chooses each action and DOM field, Playwright acts.
jev-windows-voice
Türkçe ve İngilizce doğal konuşmayla Windows 10/11 bilgisayar kontrolü: OpenAI Realtime, local Whisper, Jev, UI Automation ve Playwright.
computer_use
MacOS computer use driven by Jev (TypeSafe System One) as the decision maker.
jev-browser (tontoko)
One grounded Jev/Playwright core: typed SDK, persistent CLI, and MCP server with native browser operations and deterministic assertions.
jev-frontend-qa
Evidence-driven frontend QA built on Jev Ultrafast and Browser Harness, with a synthetic todo demo.
jev-mobile
Fast structured Android control loops with TypeSafe Jev and Mobile MCP.
jev-shield (vmendes90)
Privacy-first Chrome extension that semantically blocks native ads, sponsored feed cards, and video ads using TypeSafe Jev.

Almond-fastloop: Almond's browser computer-use rig (Chrome DevTools + TypeSafe Jev), and the Browser Use Olympics benchmark it is measured on.
barrunto
A Chrome extension that brings TypeSafe's Jev to X.com to analyze posts as you browse.
jev-ra
Browser use for coding agents, 3-5x faster than browser-use. MCP server + CLI; TypeSafe Jev decides every step in ~300 ms.
jevcumber
Write Cucumber tests with just the .feature file. No step definitions — Jev (TypeSafe AI) resolves each Gherkin step and Playwright runs it.
otto
Open-source native computer use for macOS and Windows: TypeSafe Jev, local OCR, and selective planning.
psearch
Parallel web search for terminals and agents, with local Chromium and Jev-guided exploration.
