How to convert MP3 to text in 3 steps

1
Upload your MP3

Click "Upload audio" on the ScribeForge homepage or drag and drop your MP3 file directly. Files up to 100 MB are supported — that's roughly 100 minutes of speech at standard quality.

2
Wait ~10–30 seconds

ScribeForge sends your audio to the xAI Grok Speech-to-Text API (grok-stt). Transcription speed depends on file length — a 5-minute recording typically completes in under 15 seconds.

3
Copy or download your transcript

The transcript appears with speaker-segmented paragraphs and timestamps. Copy to clipboard or download as a .txt file. No watermarks, no signups required.

What audio formats does it support?

ScribeForge accepts all common audio and video container formats, not just MP3:

MP3
WAV
M4A
OGG
FLAC
WEBM
MP4
AAC

If your file isn't in one of these formats, convert it first with CloudConvert (free, no account needed) or with VLC's built-in export.

Is it accurate?

ScribeForge uses the xAI Grok Speech-to-Text API (grok-stt) — launched April 18, 2026. On xAI's official phone-call entity recognition benchmark, Grok STT reports a 5.0% error rate vs ElevenLabs 12.0%, Deepgram 13.5% and AssemblyAI 21.3%. In our own tests across 6 different audio conditions (noisy environments, heavy accents, technical vocabulary, multiple speakers), Grok STT achieved the lowest WER of any model we tested. See our full comparison against Whisper and Deepgram.

Accuracy is highest when:

Does it detect the language automatically?

Yes. Grok STT detects the language automatically — you don't need to specify it. It works across 25+ languages including English, Spanish, French, German, Italian, Portuguese, Mandarin, Japanese, Arabic, Hindi, and more. The transcript response includes the detected language alongside the text, and Grok handles seamless mid-stream language switching.

If you know your recording is in a specific language, you can also type it in the optional language field before uploading to get slightly better results on ambiguous audio.

What do I get in the output?

The transcript includes:

Word-level timestamps are available if you use the API directly.

Free tier

The free tier gives you an instant 200-character preview of any audio file (up to 100 MB) with no account required. Try as many files as you want — upgrade to see full transcripts.

If you transcribe regularly — interviews, weekly podcast episodes, meeting recordings — a paid license is more practical. The credits_50 plan gives you 50 full transcriptions for a one-time purchase. The monthly plan is unlimited.
