Orb: Local AI Assistant

Orb is a private AI app that runs on your Android phone. No cloud, no account, no subscriptions. Your conversations stay on your device.

Most AI apps send every message to a remote server. Orb runs AI models directly on your phone instead, so your data does not need to leave it. Use it on a plane, underground, in airplane mode, or anywhere with no signal. No Wi-Fi needed after setup.

QUICK TO START

Orb starts you on its lightest model, so your first download is small and you can start chatting in minutes. Larger, more capable models are one tap away, and Orb recommends the one that suits your phone.

WHAT YOU GET

• Offline AI: works without internet after a model is downloaded
• Private by design: chats stay on your phone, never synced to a cloud account
• No account: no sign-up, email, API key, or login
• One-time purchase: no subscription, no recurring plan
• No ads
• Works in airplane mode after setup

FEATURES

• Offline AI chat: natural conversations without an internet connection
• Image generation: create images on your phone, on supported devices
• Image understanding: describe photos, read text from receipts and screenshots, answer questions about what you see
• Document questions: ask about PDFs and text files without uploading them
• Voice: speak to Orb with on-device Whisper, and hear replies read aloud
• Multiple local models: Qwen3.5, Qwen3-VL, LFM2.5-VL, MiniCPM-V, and Gemma
• Automatic hardware detection: uses NPU, GPU, or CPU, whichever your phone supports best

BUILT FOR PRIVACY

Privacy is not an add-on. It is how Orb works. There is no account to hack and no cloud chat history to expose.

• Conversations stay on your phone
• No telemetry, analytics, or third-party crash reporting
• No network needed after models are downloaded
• Good for private writing, sensitive work, research, and journaling

OPTIONAL WEB SEARCH, OFF BY DEFAULT

Orb can look things up on the web, but only if you turn it on. After a clear warning, the words you ask Orb to search for are sent to Brave Search to fetch live results. That is the only thing that ever leaves your phone: just the search text, never your chats, images, voice, or files. Leave it off and Orb stays fully offline.
