Rosettica is a privacy-first AI translation app for iPhone, iPad, and Mac. Translate text into multiple languages at once with TranslateGemma running on-device, stream results in real time, and keep your data off third-party servers. Powered by TranslateGemma 4B on Apple's MLX framework, Rosettica runs fully on-device for maximum privacy. You can also connect to your own OpenAI-compatible server, or let your iPhone use your Mac as a local translation server over Wi-Fi. KEY FEATURES: β’ On-Device AI Translation β Run TranslateGemma locally on Apple Silicon. After a one-time model download, translation works entirely offline with no cloud APIs. β’ Local Network Translation (Mac + iPhone) β Turn your Mac into a translation server for nearby iOS devices. Your iPhone discovers the Mac automatically via Bonjour on the same Wi-Fi network and offloads translation to the Mac's more powerful hardware. All traffic stays on your local network. β’ Multi-Target Translation β Translate to multiple target languages simultaneously. Each language gets its own live-updating card with real-time streaming output. β’ Automatic Source Language Detection β Rosettica detects the source language automatically using on-device NaturalLanguage analysis. You can also override the detected language manually. β’ 55+ Language Coverage β Built on TranslateGemma, benchmarked across 55 core languages including Chinese, Japanese, Korean, Arabic, Spanish, French, German, Hindi, and more. β’ Image-to-Text Input (OCR) β Extract text from photos, camera captures (iOS), or imported image files (Mac), then translate it instantly. β’ Flexible Backends β Switch between on-device, remote server, or local network modes in Settings. β’ Multiple Remote Endpoints β Configure and prioritize multiple OpenAI-compatible endpoints (LMStudio, vLLM, Ollama, etc.) with connection testing, model discovery, and drag-and-drop reordering. β’ Performance Controls β Tune max parallel translation tasks to balance speed and memory usage for your hardware. No upper limit β you decide based on your device. β’ Translation History + Search β Every translation is saved locally. Browse, search, and copy past results anytime. β’ iCloud Backup & Restore β Back up and restore your translation history using your own iCloud account. β’ Privacy First β No analytics SDKs, no tracking, no account required. Your translations stay on your devices. Rosettica is free with an optional tip jar. Built for people who need fast multilingual workflows while staying in control of where their data is processed.
