Every AI package found, with size, tier and what else stops	Free space measured before and after (demo mode, simulated Pixel 9)

---

Android phones now ship with on-device AI that downloads large models in the background. Google says AICore, which runs Gemini Nano, normally takes about 7 GB on a Pixel and 11 GB or more while a model update is in progress (Google, Tech Advisor). Samsung, Xiaomi, Motorola and OnePlus add their own AI engines on top.

RemoveAndroidAI is the Android sibling of RemoveWindowsAI and RemoveMacAI. It finds the AI packages on your phone, tells you what each one does and what stops working without it, and turns off the ones you pick.

• No root, no app to install on the phone. It uses Android's own pm disable-user, the same switch as Settings → Apps → Disable.
• Nothing is uninstalled. Turned-off packages stay on the phone and can be turned back on at any time.
• Every change is recorded in an undo file, so one click or one command puts everything back.
• Conservative by default. Only packages whose loss affects AI features alone are pre-selected. Packages that also break other features (Live Caption, search, autofill) are listed but left unticked. Packages known to break phones are listed and never touched.
• Every package has a source. The list is cross-checked against Universal Android Debloater (next generation) and links its evidence.

Use it

You need a computer, a USB cable and USB debugging turned on: Settings → About phone → tap Build number 7 times, then Settings → System → Developer options → USB debugging. On Samsung, Build number is under About phone → Software information.

In the browser

Open https://maximilianfeix.github.io/RemoveAndroidAI/ in Chrome, Edge, Brave or Opera, click Connect phone, and tap Allow on the phone. The page talks to the phone directly over WebUSB. Nothing is uploaded anywhere.

If the browser can't claim the phone, another program is holding the USB connection: close Android Studio and run adb kill-server.

Command line

Needs Node.js 20+ and adb (platform-tools; macOS: brew install android-platform-tools, Windows: winget install Google.PlatformTools).

npx github:maximilianfeix/RemoveAndroidAI            # show what would be turned off; changes nothing
npx github:maximilianfeix/RemoveAndroidAI --apply    # turn it off (asks first)
npx github:maximilianfeix/RemoveAndroidAI --undo     # turn everything back on

Options: --include-caution also selects packages that break other features, --serial <id> picks a phone when several are connected, --json prints the scan as JSON, --yes skips the question.

The CLI prints free space before and after, measured with df on the phone, so the number is what you actually got back.

With a coding agent

Point Claude Code, Codex or any agent with a shell at this repo and say "turn off the AI on my phone". AGENTS.md tells it how to do that safely.

Undo

• Web: the page keeps an undo record in your browser and offers it as a file to download. Reconnect and click Undo last run, or Undo from file.
• CLI: --undo uses the record saved in ~/.removeandroidai/.
• By hand: Settings → Apps → (show system apps) → the app → Enable, or adb shell pm enable --user 0 <package>.

Undo only turns back on what RemoveAndroidAI turned off. Apps you had disabled yourself stay disabled.

Model data deleted with pm clear is not restored by undo. The apps download it again when they need it.

What it turns off

Tiers:

• safe: only AI features stop. These are pre-selected.
• caution: other features stop too, or the package isn't in UAD-ng's list yet, so its side effects are unverified. These are not pre-selected.
• never: listed so they can't be removed by mistake. RemoveAndroidAI refuses to touch them.

Google packages are checked on every phone; vendor packages only on that vendor's phones.

Missing a package, or found one that breaks something? Open an issue with the phone model, Android version and a source. The list lives in data/packages.json.

How it works

1. Reads the phone's maker and Android version (getprop) and the installed packages for the main user (pm list packages --user 0).
2. Matches them against data/packages.json and reads sizes from Android's daily storage stats (dumpsys diskstats).
3. For each package you pick: pm disable-user --user 0 <package>, then, for packages that hold downloaded models, pm clear --user 0 <package> to delete them.
4. Writes each change to the undo record as it happens, then measures free space again with df.

Package names are checked against a strict pattern before they reach the shell, and a package marked never is refused even if it is passed in directly.

Status

Version 0.2. The commands and output parsing are tested against an Android 16 emulator and a simulated phone in the test suite. It has not yet been tested on enough real phones: a device report with what was freed and what stopped working on your phone is the most useful thing you can send. Some vendor packages are marked caution only because nobody has verified their side effects yet.

Use it at your own risk. Nothing here is permanent, but a phone without a feature you relied on is annoying even when it's reversible.

Development

npm install
npm run check        # typecheck, tests, CLI bundle and web build
npm run dev          # web app on localhost (WebUSB works on localhost)
node scripts/readme-table.mjs   # regenerate the table above from data/packages.json

dist/cli.mjs is committed on purpose so npx github:… works without a build step. Rebuild it with npm run build:cli when you change src/.
