Frequently Asked Questions

Find Quick Answers

What formats are supported for input?

The tool accepts MP3, WAV, and M4A audio files. If your file uses an uncommon codec, convert it to a supported format before uploading. Large files may require chunking for processing.

Is the output text searchable?

Yes. The generated PDF embeds the transcript text, allowing full-text search within the document and easy copying of sections for review or citation.

How private is my data?

Uploads are processed on secure servers and are not shared with third parties by default. Downloads are available for a defined period; store or delete data according to your policy.

Can I edit the transcript after generation?

The PDF contains an embedded transcript suitable for reading and copying. To edit, you can re-run with corrections or extract the transcript text for external editing.

Are there limits on file length or daily usage?

There is no strict stated daily limit. Very long files may be chunked during processing. For large-scale needs, consider batching audio files into smaller segments.
