TaskMasterBrowser is a web browser with an AI agent built in. Describe a task in plain English, for example "find the top headline on bbc.com/news", and the agent opens websites, reads them, clicks, types and fills in forms while you watch. You can pause it, take over the page yourself, or stop it at any moment, and every step it takes is listed, with a screenshot for most of them.
TWO WAYS TO RUN IT
Cloud (Claude): uses your own Anthropic API key. To decide what to do, the agent sends your task and screenshots of the pages it is working on to Anthropic. You pay Anthropic directly, and each task stops by itself at an estimated $1.50. The app has no key of its own and no server of ours in between.
On-device (Gemma): uses Google's Gemma 4 E2B model, a 2.6 GB file you download from Settings (use Wi-Fi). Once downloaded, the model runs on your phone, so the pages it reads are not sent to an AI service. It is slower and less capable than Cloud, and needs a 64-bit ARM phone with 8 GB of RAM or more. The websites you visit still see your requests, as in any browser, and if your task doesn't name a site the app opens a Google search containing your task text.
YOU KEEP THE LAST TAP
Before the agent presses a button that looks like a purchase, a send or post, or a delete, it stops and asks you. It never types a password: if a page needs you to sign in or solve a CAPTCHA, it hands the page to you. The check works from the button's label, so it can miss an unusual one. Watch what it does, and use a virtual or single-use card number for purchases.
SAVED INFO FOR AUTOFILL (optional, on-device mode only)
Save your name, address or card details and the on-device agent can fill them into forms. They are encrypted with the Android Keystore, kept only on your phone and excluded from backups. The model asks for "the email field" and the app types the real value itself; saved values are masked before the model reads a page. A website still receives whatever is typed into its form, as if you had typed it. Saved info is never used in Cloud mode.
Add details by typing them, by importing one contact with Android's contact picker (the app sees only the contact you pick), or by scanning the front of a card with your camera app. The photo is read on your phone and deleted straight away, and only the text you confirm is saved.
ALSO INCLUDED
- Task history you can run again or edit
- Saved tasks and ready-made examples
- Copy or share any result
- Model download with progress, storage use and delete
- Tablet and landscape layouts
PRIVACY
No accounts, no ads, and no analytics or tracking of our own. We run no server and collect nothing. The app asks for internet access only. Card scanning uses Google's ML Kit text recognition on the phone, and that library may send anonymous diagnostics to Google. Cloud mode sends your task and page screenshots to Anthropic under its terms. Settings has a page that explains all of this and can delete everything the app stores.
A NOTE ON TRUST
This is an independent app, not affiliated with Anthropic or Google, and it has not been professionally security-audited. AI agents make mistakes: check what it did before relying on a result.
