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.
