AI Offline Translator

AI Offline Translator runs a real large language model on your device. No cloud, no account, no internet after setup. == Free, plus one optional one-time purchase == Free forever: whole-file translation — import and translate PDF, DOCX, TXT, MD and RTF documents at no cost — plus text translation in 29 languages (up to 1,000 characters per translation on the Translate screen), photo translation with OCR, voice translation, favorites, history and PDF export. Optional one-time in-app purchase ("Long Text Pro"): full translation of texts longer than 1,000 characters, up to 10,000 characters, on the dedicated Long Text page. Try before you buy — longer texts are translated free up to the first 1,000 characters, so you can judge the quality before unlocking. No subscription, and nothing else is locked. == Setup: one download, then offline forever == The app ships without a model. On first launch, download it once over Wi-Fi (main model about 1.1 GB, lightweight about 400 MB). After that everything runs offline, Airplane Mode included. The app checks your free storage space and warns you before downloading. == Why offline matters == - Your text never leaves the device: no server, no upload, no analytics SDK, no ads. - Works on a plane, in the subway, or abroad without roaming. - No account, no sign-in, no rate limits, no monthly fee. == Features == - 29 translation languages, any-to-any, source language detected automatically - Whole-file translation — PDF, DOCX, TXT, MD, RTF — completely free - Long Text page for texts up to 10,000 characters - Photo translation with on-device OCR - Voice translation (7 languages via Apple's on-device speech packs) with text-to-speech readback - PDF export with clean formatting, favorites, and history encrypted on device - Interface in 50 languages, follows your iOS system language - Native iOS design, light/dark/system, Dynamic Type and VoiceOver supported == Engine == Qwen2.5 1.5B running on llama.cpp with Metal GPU acceleration — fast, and close to cloud quality for everyday text. == Permissions == Camera, photo library and microphone are requested only when you use photo or voice translation.
