01 / WHAT IT DOES

Runs on your phone.

The model runs on your Android device. Research questions, local search, and answer generation stay on the phone.

Read the sources.

Open a numbered citation to inspect the saved passage. Check whether it supports the answer.

Choose your collections.

Add knowledge collections for the subjects you care about. Download before you leave, or import a compatible saved pack.

Ask about your files.

Attach a PDF, a text file, or a photo of a printed page. Text is read on the phone, and the answer cites the file.

04 / FAQ

Common
questions.

Need help?
Ask on GitHub

Does it really work offline?

Yes, research works offline after setup. Install a model and any collections you want first. Downloads and catalog refresh need an internet connection; research uses the files already on your phone.

Do I need a knowledge collection?

No. A model is required, but collections are optional. The model can answer general questions without a collection, but those answers aren’t checked against saved sources. If you ask it to use only sources and it can’t find enough information, it will say so.

How much should I trust an answer?

Treat it as a starting point, not a guarantee. Models can make mistakes, and a citation does not prove a claim. Read the linked passage and check its context and date. The current collections do not cover every subject.

Can it find places near me?

Yes, with the Essentials or Vegan places collection. Ask for “nearest pharmacy”, “ATM near me”, or “vegan restaurants near me”, and the app reads your phone’s location through Android, after explaining why and asking permission. GPS works without a connection, and the location never leaves the phone. You can also name a city instead.

What stays on my phone?

Research questions, local search, and answer generation stay on the device. There’s no account to create. User-requested downloads contact the model or collection host; this website’s downloads are served by GitHub.

Will it work on my Android phone?

The app requires Android 13 or newer and an arm64 processor. Performance and available storage matter when running a local model. It has been tested on an Infinix X6840 and a Redmi 13C; performance on other devices may differ. Allow additional space for model and collection files.

How do I install or update it?

Open the downloaded APK and follow Android’s installation prompts. Public releases use the same project signing key. A locally test-signed build cannot be updated with the public APK; preserve your data before considering a reinstall. See the installation notes.

05 / COMMUNITY

Community token

ATLAS was launched by the community on Bankr, with its creator fees and creator allocation going to the dev. Field Atlas adopted it to reward contributors; it did not create or sell it. No token is needed to use the app.

Not financial advice or a promise of ongoing token support. Tokens can lose all their value.

Base

External platforms · Not required for the app

Robinhood

Also named ATLAS, launched by the dev on Pons on 3 November 2026. Its 2% creator fee goes to the dev's wallet: half is used to buy and burn the token, half funds building Field Atlas. It does not pay contributor rewards. The dev's wallets are listed in CONTRIBUTING.md; their balances are public on the explorer.

Contributor rewards

Get paid in ATLAS for work that gets merged: fixes, features, phone timing reports, and wrong-answer or safety reports that lead to a fix. Each task states its amount before you start, usually 5 to 50 million ATLAS. Posts and promotion don’t count.

Nobody from Field Atlas will ever ask for a key, a seed phrase or a payment.

Rewards paid

From 1,000,000,000 ATLAS put into a separate pool wallet on 1 November 2026. Only the maintainer signs for it, and it is not locked.

Pool wallet (Safe on Base): 0x527C6fb80013882280CE4DB88E720F0fd8b1AEa2

DateWhoWorkATLASTx
Every payment is listed in rewards.json on GitHub.

The dev’s wallets receive the ATLAS creator fees and the launch’s creator allocation (15 billion ATLAS vesting until 26 September 2027). 1 billion ATLAS from the dev’s holdings is in the separate contributor pool. The rest belongs to the dev, to use as they choose, including funding further work on Field Atlas.
