Everything you need to capture and understand audio

Professional-grade recording with the intelligence of modern AI, built for everyday use.

AI Transcription

Automatic speech-to-text with timestamps and speaker labels. Supports Koder AI, OpenAI, Anthropic, and Google — choose your backend.

Interview Mode

Stereo recording captures two speakers on separate channels. Visualize amplitude per participant and get diarized transcripts automatically.

Interpreter Mode

Real-time phrase-by-phrase translation in 10 languages. Perfect for multilingual meetings — each speaker's segment is translated and color-coded.

Audio Editing

Non-destructive Trim, Cut, and Concat operations with a draggable waveform editor. Powered by FFmpeg — no re-encoding, lossless quality.

Truly Cross-Platform

One app across Android, iOS, Linux, macOS, Windows, and Web. Your recordings sync via the device file system — no vendor lock-in.

Smart Library

Organize by categories and tags. Full-text search, bulk edit, sort by date or duration. Soft-delete with configurable auto-purge (7–60 days).

From recording to insight in seconds

Koder Dek handles the entire pipeline — you just hit record.

Record once, understand forever

The moment you stop recording, Koder Dek uploads your audio to Koder AI Voice and returns a fully timestamped, speaker-labeled transcript — ready to search, share, or export.

  • Timestamps down to the millisecond
  • Speaker diarization out of the box
  • Automatic summary and keyword tags
  • Works with Koder AI, OpenAI, Anthropic, and Google

Break language barriers in real time

Interpreter Mode turns Koder Dek into a live interpreter. Each speaker records their phrase, and the app transcribes and translates it instantly — showing both the original and the translation side by side.

  • 10 languages: EN, PT, ES, FR, DE, IT, JA, ZH, KO, AR
  • Swap language direction with a single tap
  • Full conversation history with colored segments
  • Export the bilingual transcript as text

Frequently Asked Questions

Everything you need to know before you hit record.

Is Koder Dek free to use?
Yes — Koder Dek is free to download and use. AI transcription requires a connection to Koder AI Voice (included) or your own API key for OpenAI, Anthropic, or Google. No subscription is required for recording, playback, and editing.
Which platforms are supported?
Koder Dek runs on Android, iOS, Linux, macOS, Windows, and Web — all from a single Flutter codebase. You can start a recording on your phone and access the transcript on your desktop using the same account.
Does transcription require an internet connection?
Yes, AI transcription uses Koder AI Voice (voice.koder.dev) and requires an internet connection. Recording, playback, editing, and library management all work fully offline.
What audio formats does Koder Dek support?
Recordings are saved in AAC-LC format (.m4a) at 128 kbps / 44100 Hz — a near-perfect balance of quality and file size. Audio editing (Trim, Cut, Concat) uses stream-copy via FFmpeg, so there is no quality loss on operations.
Is my audio data private?
Recordings are stored locally on your device. When transcription is enabled, audio is uploaded over HTTPS to the selected AI backend and deleted after processing. Koder does not retain copies of your recordings.
