Talk to any AI.
Answer to no one.

An open-source AI workspace for Android. Bring your own keys — or none at all — and every word stays on your phone.

Take the tour.

Follow the line — one idea per stop.

01Models

Bring any brain.

The entire OpenRouter catalog, direct keys to the big providers — or a model that lives on the phone itself. Pull one in-app, import your own GGUF, swap mid-chat.

02The plus button

Superpowers, filed under +.

Everything bigger than a message, one tap away.

  • Web search — free for everyone, no key
  • Deep Research — cited reports, runs in the background
  • Data Agent — answers as tables, not prose
  • Echo Agents — a model with its own tools

03 — The reader

Feed it anything.

A document engine ships inside the APK: Word, Excel, PowerPoint, PDF, EPUB become clean Markdown on the phone, scans go through on-device OCR — so even a local model with no internet can read your files. Nothing is uploaded just to open a document.

04Dictation

Stop typing. Say it.

Dictate in any chat or project. It has its own model and its own key, independent of who's answering.

05Imagine

Picture something.

Describe it, then refine it out loud — “make the sky purple.” Ask for video and close the app; it renders anyway.

06Background work

Walk away. It pings you.

Research, video renders and downloads keep running with the screen off, then land as one tidy notification. Plain replies never buzz — that's not news.

07Your network

Your PC thinks. Your phone talks.

Point it at the Ollama or LM Studio box on your desk and answers stream over Wi-Fi, token by token. No cloud, no key, no bill — the model never leaves your house.

08Projects

Give your chats a home.

A project is a room that already knows your files and your rules. Drop the lease and its amendments in once — every chat inside starts briefed, and stays that way.

09The drawer

Everything, one swipe away.

Pinned chats, full-text search, Projects, the Artifact Gallery — the whole app hangs off the left edge.

10Artifacts

Ask for a thing. Keep the thing.

Pages, reports and documents a model builds don't scroll away — they land in the gallery, versioned, ready to reopen and revise.

11Appearance

Wear it your way.

Seven accents, light and dark, or Material You matching your wallpaper. Don't take our word for it — tap a seal and watch this panel change its clothes.

12Privacy

No account.
No EchoFlow server.
No telemetry.

There is nothing between you and your model. Keys go straight to the provider you chose, chats live in a database on your phone, and the entire codebase is MIT-licensed so you don't have to take anyone's word for it. The fine print →

Put it on your phone.

One APK. Android 7+. Free forever — it's your hardware and your keys.
