Diktafon: Voice Memos on Tape
Private, on-device transcripts
Free · Designed for iPad. Not verified for macOS.
Every memo transcribed and summarised on your device — no account, no cloud, no ads. Your voice never leaves your phone.
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 device. 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
Ten languages: English, Czech, French, German, Korean, Polish, Portuguese, Russian, Spanish and Turkish — 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 device. Their quality is being actively worked on and will improve in future updates.
Diktafon works best on devices with 4 GB of RAM or more.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• New home screen: cassette tiles in the app icon's pixel-art style.
• Clearer transcripts: bundled voice-activity detection cuts background-noise ghost words and hallucinations.
• Snappier summaries: one-line memo gists, short memos skip the summary step, and suggested cassette titles name the topic.
• Memos no longer get stuck at "transcribing" after the app is interrupted mid-job — stuck memos self-heal on launch.
• Playback and recording errors are surfaced instead of failing silently; fixed the jumpy cursor after tapping a transcript word.
