Memoria - Local AI

Memoria is a fully offline AI chat assistant. Everything runs inside your iPhone. No signal needed, ever. Not a single byte of your input is sent outside. On top of that, long-term memory across sessions means it remembers your conversations.

Translate a menu mid-flight at 35,000 feet. Plan tomorrow's meeting from a remote campsite, no signal. Catch a fleeting idea on a subway platform 200 feet underground. Memoria just works.

■ When Memoria shines

Travel and flights: No data roaming, no spotty airport Wi-Fi. Translate, draft, and answer anywhere on Earth. Zero data charges.

Underground, mountains, anywhere offline: When everything else stops working, Memoria keeps going.

Sensitive topics: Work problems. Health. Money. Family. Things you would never paste into a cloud AI. Memoria handles them on-device.

Journal, learning log, thinking out loud: Memoria remembers what you wrote last week. No re-introducing yourself every conversation.

Language learning: Chat, translate, and grammar-check across English, Japanese, and Spanish. Save vocabulary to memory and recall it any time.

■ Key features

Fully offline, no signal needed
Everything runs inside your iPhone. Gemma 3 1B (Google DeepMind) runs locally. A one-time 600MB Wi-Fi download, then airplane-mode-friendly forever. No "server busy", no API errors. Cloud chat AIs depend on external servers and stop working the moment you lose connection. Memoria does not. Where signal drops out, the plane, the mountain hut, the underground, is exactly where Memoria comes into its own. Not a single byte of your input or voice ever leaves the device.

Long-term memory across sessions
Plenty of AI apps run offline, but most have no memory. Each new chat is a blank page. You keep retyping who you are. Memoria is different: conversations are auto-summarized into SQLite and past context is injected into every new chat. Cloud AIs offer memory too, but it costs a monthly subscription and lives on their servers. Memoria's memory lives entirely in your iPhone, every byte. No signup, no subscription, zero external transmission.

Trilingual native support
UI and voice input both support English, Japanese, and Spanish. Type in Japanese, get English back. Have your English grammar explained in Japanese. Cross-language workflows feel natural. Perfect for expats, students abroad, or international travelers. Works without signal in foreign countries.

Offline voice input
On-device speech recognition for 3 languages. Your voice never leaves the device. Pronunciation practice, hands-free notes, foreign-language shadowing.

Powerful slash commands
/english /japanese /spanish for translation. /cal for English grammar and phrasing check. /grammar for detailed grammar explanations. /remember to save to global memory, /memory to view saved memories. With /addcommand, register your own repeated workflows in plain language. No code required.
