About this app

The AI assistant that never phones home.

Localyze.ai runs a full AI model directly on your phone's processor. Ask anything, draft emails, get code, analyze images, plan trips — with zero cloud. Your questions are answered by your own hardware, so nothing you type, say, or photograph ever leaves your device.

WHY ON-DEVICE BEATS CLOUD AI
• Works offline — on a flight, in the metro, in a dead zone. After the one-time model download, no internet is needed at all
• Truly private — cloud AI sends every word to a server. Localyze physically cannot: there is no server
• No account, no login, no email — open the app and start chatting
• Unlimited use — no message caps, no "you've reached your daily limit"

HOW IT WORKS
1. Pick an AI model tier (Fast ~380 MB or Accurate ~2.6 GB) — downloaded once over HTTPS
2. Chat by text, voice, or photo
3. Everything runs and stays on your phone

WHAT YOU CAN DO
• Ask questions and get detailed answers, offline
• Draft and rewrite emails and messages
• Dictate with on-device voice input
• Analyze photos with the camera or gallery
• Get charts and tables from your data, rendered natively
• Use the code workspace for programming help
• Search, pin, and export your chat history
• Optional memory so your assistant learns your preferences — stored encrypted on your phone, deletable anytime

PRIVATE BY ARCHITECTURE, NOT BY PROMISE
Cloud chatbots ask you to trust their privacy policy. Localyze removes the need for trust: chats are processed on your CPU/GPU and stored in an encrypted local database. We operate no servers and cannot read your conversations even if we wanted to.

• Chats, voice, photos, memory: never transmitted
• Local database encrypted with SQLCipher
• Optional crash reporting is the only network feature, and you can switch it off in Settings

BUILT FOR REAL PHONES
Localyze is engineered to run modern open AI models (Google's Gemma family and Qwen) on everyday hardware, including mid-range Snapdragon devices.
• Recommended: Android 9+, 4 GB+ RAM, GPU acceleration supported
• Two tiers: Fast for instant replies, Accurate for the smartest on-device answers
• Honest performance: answers take a few seconds to a minute depending on your phone — that is the trade for total privacy

LOCALYZE PRO (optional, in-app)
The smartest Accurate model, tool-using assistant, inline charts, and the code workspace. One yearly or one lifetime purchase — no recurring monthly fees.

NOT FOR YOU IF YOU NEED
• Cloud sync across devices
• Live web answers about today's news
• Instant sub-second responses on older phones

Your phone is powerful enough to run your own AI. Own it.
