One App — Two Superpowers

Ask anything. Say everything.

Rose AI pairs a private assistant with a full offline translator — both running on the chip already in your pocket.

01 — Assistant

Ask anything

Draft messages, plan trips, decode menus, get answers — a real AI assistant that works with the internet switched off.

  • Vision, documents, and voice — one chat
  • No logs, no training on your words
  • Powered by Gemma, fully on-device
Live on iOS
02 — Translator

Say everything

Translate between English and 54 more languages by text, photo, camera, or speech — instantly, accurately, and entirely offline.

  • Four modes: type, snap, point, or speak
  • AI pronunciation for non-Latin scripts
  • English + 54 languages, zero servers

Meet the Rose AI Assistant

The first assistant that can keep a secret.

Most AI assistants send every word you type to a data center. Rose runs Google's open Gemma model on your device's own GPU through Apple's Metal — so it can draft, plan, answer, and explain with the internet switched off. Your questions stay between you and your phone.

  • Ask, then translate the answer — one conversation
  • Attach photos and documents — Rose sees the real pixels
  • Never logged, never used for training, never seen

Of course — here's a courteous version: 「チェックアウトを14時まで延長していただけますでしょうか。」 Want it more casual?
Beyond Chat

One assistant, many talents

Attach it, say it, ask it — everything below happens on your device, and nothing is uploaded.

Vision

Sees your photos

Attach up to four photos from your library or camera. Scenes, menus, receipts, labels — Rose reads the actual pixels, on-device.

Documents

Reads your documents

PDF, Word, text, Markdown, CSV, JSON, even code files — extracted on your device and discussed right in the chat.

Voice Mode

Talks it through

A full-screen, hands-free conversation: speak naturally, hear Rose's replies out loud, and tap to interrupt anytime.

Markdown + Math

Answers worth reading

Headings, tables, and code blocks with a copy button — and formulas that render as clean symbols, on screen and when copied.

Personas

Switches hats

Pick a persona for writing or code, and flip on thinking mode when a question deserves step-by-step reasoning.

History

History that stays home

Auto-titled and searchable. Pin, rename, edit & re-run, regenerate — or export whole chats as Markdown. Stored only on your device.

Translation Modes

Four ways to say it

Type it, snap it, point at it, or speak it — Rose AI translates between English and 54 more languages on the spot, no signal required.

Type & Translate

Enter text and get instant translations. Perfect for composing messages, emails, or preparing phrases before conversations.

  • Instant bidirectional translation
  • Copy translations with one tap
  • AI pronunciation guides included

  • On-device OCR — photos never leave your phone
  • Built for menus, signs, and documents

Point & Translate

Open the live camera and point at the world — capture a frame and Rose's vision model reads the whole scene, then translates what it sees.

  • Real-time viewfinder, one-tap capture
  • Vision AI reads whole scenes, not just words
  • Nothing you capture ever leaves the phone

Speak & Translate

Talk face-to-face: speak, then hear it in their language. Their side appears as translated text; your side is spoken aloud.

  • Hands-free listening with adjustable pause sensitivity
  • Per-turn replay and a big-text view for across the table
  • Every word processed on-device

Privacy First

Cloud AI vs Rose AI

Every prompt you type into a cloud assistant travels to someone else's computer. Rose never lets your words leave the room.

Cloud AI

  • Prompts and conversations sent to external servers
  • Chats may be stored, reviewed, and used for training
  • Requires a constant internet connection
  • One breach can expose millions of conversations
  • Your data may be shared with third parties

Rose AI

  • Every chat and translation happens on your device
  • Zero collection — nothing stored, nothing to leak
  • Works completely offline, anywhere on Earth
  • No account, no tracking, no ads
  • Impossible to breach what doesn't exist
Works Everywhere

No signal? No problem.

Rose works anywhere you go — no WiFi, no data, no exceptions.

In Flight

Translate documents and prep conversations at 35,000 feet without paying for WiFi.

Airplane Mode Ready

Remote Areas

Navigate foreign mountains, deserts, and countryside without a single bar of coverage.

Off-Grid Compatible

Underground

Read signs and menus in foreign subways and basements — anywhere signal can't follow.

Subway Approved
