Letopis is a private voice recorder with on-device speech recognition. Meetings, interviews, lectures, and voice notes become a verbatim transcript right on your iPhone: no cloud, no accounts, no analytics. Audio and text never leave the device. It is built for conversations whose content must not leave the phone: deal negotiations, legal consultations, medical and counseling sessions, journalist and researcher interviews, hiring conversations. Letopis sends neither sound nor text to any server: speech recognition and speaker labeling run on the iPhone's processor, with no internet involved. The transcript is verbatim. Every line carries its speaker and timecode; the app writes down what was said and adds no summaries or conclusions. For work where the exact wording matters. Recording starts with one tap; a level meter and timer stay on screen. When you stop, Letopis transcribes the recording and separates the speakers. Share audio or video from any other app and Letopis transcribes it the same way: messenger voice notes, including Ogg/Opus, dictaphone files, video clips. A video keeps only its audio track. Duplicates are detected by content, not by file name. What else the app does: - A built-in transcript editor: fix lines, rename and merge speakers. - Personal-data masking in the text: names, organizations, addresses, numbers - also on-device. - A synced player: tap a timecode to hear that exact moment of the recording. - Search across names and transcript text; recordings also appear in iOS search. - Custom recording names, export of text and audio. - Two recognition engines: GigaAM v3 for Russian and multilingual Parakeet (25 languages). - An optional reminder to ask participants for consent. Everything stays on your iPhone. The only network access is a one-time model download on first launch. No accounts, no ads, no analytics, no subscriptions; App Privacy says "Data Not Collected". Requires iOS 26 or newer.
