Diktafon: Voice Memos on Tape

Diktafon is a voice recorder built around one idea: capturing a thought and finding it again later should feel effortless.

Your memos live on cassettes — one tape per topic, like "shopping", "kitchen renovation" or "book ideas". Each cassette plays as one continuous tape of your recordings, in order, just like the real thing.

SIMPLE TO USE
Controls you already know, inspired by real tape recorders. Open a cassette, press record, talk — no naming, no forms, no network needed. Rewind to find it again.

MODERN
Automatic transcriptions and summaries: every memo is transcribed, every cassette summarised and titled. Tap any word in a transcript and the tape jumps right there.

COMPLETELY PRIVATE
Everything is computed on your device. No accounts, no cloud, no ads, no analytics — your voice never leaves your phone. The only network use is a one-time download of the on-device models (Wi-Fi recommended; about 2 GB for the default models, up to 3 GB for the largest — or just 0.2 GB if you skip summaries).

SPEAKS YOUR LANGUAGE
Twenty languages: Arabic, Chinese (Simplified and Traditional), Czech, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Persian, Polish, Portuguese, Russian, Spanish, Turkish, Ukrainian and Vietnamese — in recordings, summaries and the app itself. The spoken language is detected for each memo, so one tape can freely mix languages.

FREE & OPEN SOURCE
No cost, no ads, no lock-in. MIT-licensed — read the code, build it yourself, make it yours: https://github.com/jaromiru/diktafon

AND THE LITTLE THINGS
• Gapless playback with a colour-coded tape bar and an optional soft chime between memos.
• Export any cassette — or all of them — as a single archive with the audio and readable text inside; import only adds, never overwrites.
• Light & dark themes, cassette colours, per-memo copy and delete.

A note on quality: transcription and summaries come from small models running entirely on your phone. Their quality is being actively worked on and will improve in future updates.

Diktafon works best on 64-bit phones with 4 GB of RAM or more.

Recent changes:
• Background recording: keep recording with the screen off or while using another app — a notification shows the elapsed time, and recordings now survive crashes.
• Transcriptions can be edited by hand — word timings and summaries follow.
• Ten new languages (twenty in total), including Arabic, Chinese, Hindi and Japanese, with full right-to-left layouts.
• Fixed app freezes while transcription or summaries run.
