Diktafon review
A free, open-source voice note app for private offline recording and transcription.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Diktafon is a free, open-source voice memo application from MOD42 Studio s.r.o. It records spoken notes into topic-based cassette-style collections, then adds automatic transcription, summaries, and suggested titles using on-device models. The product is aimed at people who want searchable, organized voice notes without relying on an account or cloud service, particularly when offline processing and local handling matter more than collaboration features.
Its standout capability is the combination of transcription and playback navigation. Transcript-linked playback seeking lets users move from readable text to the related point in the recording, while multilingual speech detection supports recordings in multiple languages. Topic-based cassette organization gives the app a defined structure beyond a simple list of audio files. Audio and readable-text archive export also keeps recordings usable outside the app. Offline use begins after the required models have been downloaded, and the source code is publicly available under the MIT license.
Diktafon covers Android, iOS, Linux, Windows, and compatible Mac devices, giving it a broad desktop and mobile footprint. The App Store lists Mac compatibility but says it is not verified for macOS, so Mac users should weigh that qualification before choosing it. The product description centers on recording, transcription, organization, export, and offline processing rather than wider integrations. Pick Diktafon if local processing, open-source availability, and searchable voice memos are the priorities. Choose another voice note tool if verified macOS support or a broader connected app ecosystem is more important.
