WhisperKit transcribes everything entirely on your device — no audio ever leaves your phone. AI-powered cleanup automatically removes filler words and stutters for cleaner transcripts. Tap any answer to jump straight to the timestamped segment. HOW PEOPLE USE IT • Meeting recordings turned into searchable knowledge Import your meeting recordings. Ask "What was decided about the budget?" Get answers with timestamps you can jump to. • Lecture videos and study materials together Mix lecture videos, PDFs, and your notes in one collection. Ask "Explain the method in Chapter 3" — AI searches text and transcripts. • Interview recordings stay private Journalists, researchers, lawyers — your sensitive recordings are transcribed entirely on-device. Nothing is uploaded. • All your project docs in one place PDFs, Word minutes, Excel spreadsheets, audio briefings — formats don't matter. Just ask "What was decided?" • Search across languages English PDFs, Japanese spreadsheets, Thai notes — language doesn't matter. Ask in English, get answers from Japanese documents. 25 FORMATS SUPPORTED Documents (PDF, EPUB, DOCX, XLSX, PPTX, TXT, MD, CSV, RTF, HTML), images (JPG, PNG, HEIC, WebP) with on-device OCR, audio (MP3, M4A, WAV, AAC, FLAC) and video (MP4, MOV, M4V) with on-device WhisperKit transcription. Scanned and copy-protected PDFs also supported. PRIVACY FIRST Text extraction, transcription, indexing — all happen on your device. Your original files and audio recordings never leave your device. With the local LLM option, your questions and answers stay on the device too — no document text, no question, no answer is ever transmitted. With Claude API mode, only your question and relevant text snippets are sent. No account, no email, no advertising IDs, no third-party trackers. The app does send usage statistics so we can improve it — they never identify you and never include your content, and our Privacy Policy lists exactly what they contain. ANSWERS WITH SOURCES AI automatically finds relevant sections and responds with source citations — document name and page number, or audio file with timestamp. Tap a citation to jump straight to it. Summarize, translate, analyze — any instruction works. COLLECTIONS Organize documents into folders. Switch chat scope by collection for focused Q&A sessions. Supports hierarchical structure (up to 3 levels). BUILT-IN VIEWERS View PDFs, Excel, PowerPoint, EPUB, images, and audio/video transcripts directly in the app with thumbnail previews and timestamp navigation. MODEL SELECTION Use your own API key to choose between Claude Sonnet 5, Haiku 4.5, or Opus 5. Or switch to the built-in local LLM to keep your documents and questions entirely on-device.

In our testing this happened to about 1 in 5 answerable questions in English; it no longer happens, and the AI still says so plainly when the answer genuinely isn't in your documents. ### 3.5.3 — 2026-08-17 What's new in v3.5.3: • The plan screen now explains the benefit that matches what you were doing: keep asking after the free limit, or unlock stronger Claude models. ### 3.5.2 — 2026-08-13 What's new in v3.5.2: • The on-device AI now says plainly when your documents don't contain the answer, instead of stretching an unrelated passage to fit. In our testing this went from 58% to 96% of such questions. • Fixed answers starting in English when you asked in German, Spanish, French or Portuguese. Answers now begin in the language you asked in. • Fixed the on-device AI option being untappable before the model was downloaded. Tapping it now starts the download and shows the progress. ### 3.5.1 — 2026-08-11 What's new in v3.5.1: • Fixed a problem where devices that cannot run the on-device AI could still download a model that would never work. Those devices now clearly say so instead. • Cloud AI continues to work on every supported device. ### 3.5 — 2026-08-10 What's new in v3.5: • Fixed a problem where a failed import could look like it succeeded, even though nothing was actually brought in. • Fixed a problem where re-importing a document with the same name could delete the copy you already had, if the new import failed. • Switching to the on-device AI now starts downloading the model. Before, it only changed the setting, and you found out it was missing when you asked a question. • Fixed search for languages that separate words with spaces, such as English and German. • A question blocked by the daily limit now continues after you subscribe, instead of being lost. • Replaced the built-in sample document with something closer to a real one. You can try finding a single line in a long contract, reading a page that is only an image, and asking about a foreign-language clause in your own language. ## Apps similar to LocalRAG! | App | Rating | Price | Category | | --- | --- | --- | --- | | [MLC Chat](https://appshunter.io/ios/app/mlc-chat/id6448482937) | 4.2 (78) | Free | Productivity | | [Enclave - Local AI Assistant](https://appshunter.io/ios/app/enclave-local-ai-assistant/id6476614556) | 4.7 (1,029) | Free | Productivity | | [Local LLM: MITHRIL](https://appshunter.io/ios/app/local-llm-mithril/id6751945393) | 4.4 (13) | Free | Productivity | | [Solair AI](https://appshunter.io/ios/app/solair-ai/id6758450823) | 4.3 (23) | Free | Productivity | | [Noema: Local AI & Offline LLM](https://appshunter.io/ios/app/noema-local-ai-and-offline-llm/id6751169935) | 4.4 (21) | Free | Productivity | | [LatentChat - Assistant LLM](https://appshunter.io/ios/app/latentchat-assistant-llm/id6733216453) | 3.8 (28) | $4.99 | Productivity | ## Related topics [loosedays](https://appshunter.io/ios/topics/loosedays) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
