Diktafon vs Offscript

Diktafon is a voice memo app that transcribes and summarizes recordings on the device, then groups them into topic-based cassettes. It uses Whisper for transcription and Qwen for summaries; the models download on first run and can be changed in Settings. Each memo’s spoken language is detected, so recordings in different languages can sit in one cassette. Tap a transcript word to jump playback to that point in the recording. Cassettes can be exported as archives with audio and readable text, and imported content is added without overwriting existing items. The privacy policy says recordings, transcripts, summaries, labels, and settings remain in private app storage, and that the app collects and shares no data. Its stated network activity is limited to model downloads over HTTPS from Hugging Face and its CDN at the user’s request. The project is designed by Jaromír Janisch and is free and open source, with support for Android, iOS, Linux, and macOS.

Offscript is an Android and iOS app that turns voice recordings into searchable notes. Whisper transcribes recordings locally after an initial model download of about 100 MB, and semantic search also runs on the device. The maker says recording, transcription, search, and note workflows work offline after that download. Recordings stay on the phone rather than being sent to the maker’s servers or third parties. Audio files use AES-256-GCM encryption, while the notes database uses SQLCipher. Biometric access is supported; Android requires a secure device lock and offers secure-screen protections. Core note-taking requires no account, and the product page lists no accounts or tracking. The App Store listing says transcription covers 99 languages and the interface has 19 languages. Premium adds summaries, action items, PDF, Markdown, CSV, and plain-text exports, calendar integration, and encrypted backups. The free plan includes core voice notes, on-device transcription, and search. Premium costs $2.99 a month, $19.99 a year, or 59.99 USD once for lifetime access. Notes can be organized with tags.
