    About this tool

    Transcribe audio to text in your browser

    Transcribe audio to text free without sending files to a server. You already have the recording: an interview, a voice memo, a meeting capture, a podcast clip. What you need is editable text. This free audio to text tool runs Whisper locally in your browser. Your audio never uploads to UBIK Flow servers. No account, no cloud queue.

    That privacy-first design matters when recordings contain client names, medical details, legal discussions, or unreleased creative work. You stay in control: decode, transcribe, copy, and download on your machine.

    What this tool does

    • Accepts common audio formats: MP3, WAV, M4A, OGG, WebM, and FLAC (up to 25 MB per file)
    • Runs Whisper in the browser so transcription happens on your CPU, not our servers
    • Shows progress while the model loads and while your file is processed
    • Outputs plain text you can copy or download as .txt
    • Works without signing in: open the page and start

    How local audio transcription works

    When you drop a file, the browser decodes it and passes audio frames to a compact Whisper model loaded via WebAssembly. The first run may take longer while weights download; after that, your browser can cache them for faster repeat use.

    Processing speed depends on your device: a recent laptop usually handles a few minutes of speech in reasonable time. Very long files may feel slow, which is the trade-off for keeping everything on-device instead of shipping audio to a datacenter.

    Which free tool should I use?

    SituationBest tool
    You already have a recording fileAudio to text (this page)
    You want to speak now with record/stopSpeech to text
    You prefer pause-based live dictationLive speech to text

    Speech to text records short clips from your microphone in the browser. Live speech to text listens continuously and inserts text when you pause. Audio to text is built for files you captured earlier: commutes, calls, field notes, webinar replays.

    A practical workflow after transcription

    Raw Whisper output is rarely publish-ready. Most people run a short cleanup pass:

    1. Transcribe the file here
    2. Format timestamps, line breaks, and speaker tags with the transcript formatter
    3. Count words and estimate reading time with the word counter
    4. Scan for filler habits using the filler word counter if the source was spoken

    Privacy and local processing

    • Audio is not uploaded to UBIK Flow
    • Transcripts are not stored on our servers
    • No account means no profile tied to your files
    • Closing the tab clears in-memory state

    Tips for better accuracy

    • Choose the right spoken language in the tool if multiple options are available
    • Use clear source audio: less background noise, fewer overlapping speakers
    • Trim silence before upload if your file is very long (external editor)
    • Verify hardware with the microphone test when recording new material yourself
    • Check pacing with the speaking speed test if you plan to re-record

    Whisper handles accents and casual speech well, but no model is perfect. Review proper nouns, numbers, and homophones before publishing.
