Audio to text

Turn recordings into text without sending them anywhere

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 transcribes files locally in your browser using Whisper. Your audio never uploads to UBIK Flow servers. No account, no cloud queue, no waiting on someone else's infrastructure.

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.

When to use audio to text vs live dictation

Situation	Best tool
You already have a recording file	Audio to text (this page)
You want to speak now and see text appear	Speech to text
You prefer pause-based live dictation	Live speech to text

Speech to text records or imports short clips 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

That chain keeps every step local and free, useful for students, journalists, researchers, and anyone who documents spoken material.

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 (browser cache for the model is separate and under your control)

If confidentiality is non-negotiable, local browser transcription is a strong default. Compare that to cloud APIs that require sending full recordings over the network.

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.

Who this is for

• Students turning lecture recordings into study notes
• Writers capturing ideas on a walk, then drafting from text
• Researchers indexing interviews without cloud exposure
• Support and sales reviewing call snippets privately
• Creators repurposing podcast audio into blog posts or show notes
