Real device — a full Tetris game built end to end, on stock Android. No root, no PC, no cloud.
What is Keva?
An on-device AI agent for Android
Keva runs complete Claude Code and OpenAI Codex runtimes directly on your phone. It is built for people who want an AI agent to operate on files, code, tools, web research, and Git without a PC, root access, or a cloud desktop.
Runs on your phone
The agent runtime runs on stock Android. Your files, project data, and keys stay on the device.
Choose the engine
Use Claude Code with your provider setup, or Codex with a ChatGPT subscription or OpenAI API key.
Built for outcomes
Ask for a working deliverable — from code and repositories to a researched HTML report — not just a reply.
Why Keva
An agent that actually does the work
01
A real agent, in your pocket
Keva doesn't just chat. It reads and writes files, runs code, searches the web, and finishes the job — right on your Android phone. No PC required.
02
Private by design
Your files never leave your device. Only your messages go to the model you choose, with your own key. No trackers, no analytics, no middleman servers.
03
Two complete runtimes
Run Claude Code or OpenAI Codex — not just a model picker. Use your Claude plan, scan in with ChatGPT, or bring an API key. Switch engines mid-project without re-explaining the work.

Privacy
Your data has nowhere to go — by design
Keva keeps everything on your device: your files, your history, your keys. The only traffic leaving your phone is the conversation you send to your chosen model provider, plus a minimal, anonymous version check (no ID, no content) that stays on so we can deliver required updates. We don't run analytics. We can't see your data — and we like it that way.
GitHub
A public home for updates and feedback
Keva is a closed-source product. GitHub is where you can follow release notes, read public documentation, report issues, and share ideas — it does not include the app’s proprietary source code.
FAQ
Questions, answered
Does it need root?+
No. Keva runs entirely as a normal Android app on stock devices.
Does Keva use a cloud desktop?+
No. Keva runs the agent runtime on your Android phone. Messages go directly to the model provider you choose; Keva does not use a cloud desktop to operate on your files.
Is it free?+
The app is free. You pay your model provider directly, with your own API key — Keva takes no cut.
Which engines and models can I use?+
Keva includes complete Claude Code and OpenAI Codex runtimes. Use Claude with your existing provider setup, or Codex through a ChatGPT subscription or OpenAI API key. It also supports providers including DeepSeek, GLM, MiniMax, Kimi, and Qwen.
Does my data go to your servers?+
No. Your messages go straight from your phone to the model provider you picked. The only thing Keva's endpoint ever receives is an anonymous version-check ping (no ID, no content). It always runs — some releases require mandatory updates for security — but carries nothing about you or your data.
What can it actually do?+
Read and write files, run commands, write and execute code, search the web, and manage git repositories — on your phone's own storage.
