Documents
Reports, contracts, spreadsheets — written and polished, ready to send.
"Turn this week's notes into a three-paragraph report." You get a draft you can send as is.
Your Android phone, now the AI agent's computer.
Claude Code and Codex run on the phone with the model you choose. It works with your files, the phone's GPS and video hardware, and — with your permission — your other apps. No PC, no root.
What do you need done?
Code
Build a small tool, or fix one that won't run.
"Make me a small web page that tracks my spending by month." It creates the files and opens the page in your phone's browser.
Edit video
Turn your clips into a short, ready to post.
"Cut these clips into 30 seconds with gentle music." The film is saved as a video file on your phone.
Phone Use
With your permission, it gets tasks done in your other apps. While Phone Use works, screen content goes to your chosen model provider, never to Keva.
"Find the cheapest flight from New York to Tokyo next Wednesday." It opens Expedia, taps through, and shows you flights and prices.

- Frames are pulled from every clip with the phone's hardware decoder.
- The film is encoded on the phone's hardware encoder.
- A 1080p film, with its own piano score, saved on the phone.
Check flight prices in Expedia
Say where and when; it opens the app, taps through to the flight list and shows you the prices. You can take over or stop it at any time. While it works, screen content goes to your chosen model provider, never to Keva.
- Ask for the cheapest business fare, Shanghai to Tokyo, wide-body.
- With Phone Use on, it opens Expedia on your phone.
- It reads the screen and taps through: one-way, dates, Business class.
- It sorts by price and checks each aircraft.
- Answer: Air China, $575, nonstop A350. Nothing is booked.
Phone Use: AI that uses your apps, with you in control
With your permission, Keva can read the current screen and tap, swipe, and type in other apps. It connects through Android's own Wireless debugging (wireless ADB), paired once on the same phone. While Phone Use is working, screen content is sent to the model provider you chose — never to Keva. You can take over or switch it off at any time.
- Turn on Developer options and Wireless debugging.
- Pair by typing the code shown in an Android notification.
- Allow notifications and background running.
- Connect to Wi‑Fi (not the phone's own hotspot).
- No root or PC needed.
The first self-check screenshot is discarded and never uploaded.
Step 7: enter the pairing code
- In Settings › Developer options › Wireless debugging, tap "Pair device with pairing code". Android shows a six-digit code — leave that window open.
- Pull down the notification shade, expand Keva's "Step 7 of 8" notification and tap "Enter pairing code".
- Type the six digits into the box in the notification and tap send. Keva finishes pairing and moves on to step 8.
If the notification says it couldn't find the debugging service, keep the pairing window open and tap Retry.
Why a phone can do this
01
The phone is the computer
Keva puts a shell, files, Git, Python, Node and ffmpeg on your phone, so the agent has a real place to work. No PC, no root, no cloud desktop. It doesn't run desktop apps; it gives the agent what it needs.
02
A full agent, with the model you pick
The official Claude Code and Codex CLIs are built in. Use Claude, ChatGPT, DeepSeek, GLM, Kimi, LongCat, MiniMax, Qwen or Xiaomi MiMo, or add your own Anthropic-compatible endpoint. The agent runs on the phone; the model runs at your provider, and requests go straight there, never to Keva.
03
Your phone's GPS and video hardware
With your permission, maps tasks can use where you are; coordinates are never logged. Video is decoded and encoded on the phone's own hardware, so the 1080p film is made right on the phone.
04
Your other apps, with you in control
Pair Android's Wireless debugging with Keva once, on the same phone. Then it reads the screen and taps, swipes and types in your other apps. A floating capsule shows each step; take over or stop any time.

Your files stay on your phone
Files, chat history and keys stay on your device. What you send and the files a task uses go straight to the model provider you choose — never to Keva. While Phone Use is working, screen content goes to that provider too. Keva's own service sees only an anonymous version check (a coarse install-age range, no ID, no content) and — only if you sign in or buy — the account, license, payment and device details needed to activate. Card details are handled by Paddle. No trackers, no analytics SDKs.
Questions, answered
Does it need root?+
No. Keva is a normal Android app on stock devices.
Is Keva a cloud phone or remote desktop?+
No. Everything runs on your own phone; what a task needs goes straight to your chosen model provider.
What can it do?+
Write reports, contracts and spreadsheets; build a small tool or fix one that won't run; cut clips into a short film; and, with your permission, get tasks done in your other apps.
Can I run Claude Code or OpenAI Codex on Android?+
Yes. The official Claude Code and OpenAI Codex CLIs run on the phone: use a Claude plan or API provider, a ChatGPT subscription or an OpenAI API key. You can also use DeepSeek, GLM, Kimi, LongCat, MiniMax, Qwen and Xiaomi MiMo, or add one custom Anthropic-compatible endpoint.
What exactly runs on my phone?+
The agent runtime, its tools and your files. The model itself does not: requests go straight from the phone to the provider you choose, never through Keva.
Does Keva use my location?+
Only with your permission. The phone's GPS fix goes to the agent's maps tool for things like nearby search and routes; coordinates are never logged.
How does pricing work?+
Every device gets a 7-day trial with every feature. After that, it's a one-time license for two devices: US$39.90 (¥198). The first 100 orders get the founder price of US$19.90 / ¥98. Model usage is billed separately by the provider you choose.
Does my data go to your servers?+
Files, chat history and keys stay on your device. What you send and the files a task uses go straight to the model provider you choose — never to Keva. While Phone Use is working, screen content goes to that provider too. Keva's own service sees only an anonymous version check (a coarse install-age range, no ID, no content) and, only if you sign in or buy, the account, license, payment and device details needed to activate. Card details are handled by Paddle.
Does Phone Use need root or a PC?+
No. On the phone itself, turn on Wireless debugging (Android's wireless ADB) and pair it with Keva once by typing the code. It works over Wi‑Fi.
What happens to my screen?+
While Phone Use works, screen content goes to the model provider you chose, never to Keva. The first self-check screenshot is discarded and never uploaded.
Can I stop it?+
Yes. Take over at any time, or switch Phone Use off.
