Frequently Asked Questions
Common Questions & Technical Clarifications
What show notes and metadata does the summarizer generate?+
The summarizer generates structured Markdown episode summaries, including an episode title extracted from media metadata, bulleted key takeaways, silence and pacing metrics, and timestamped chapter markers formatted for YouTube, Spotify, and Apple Podcasts.
How are timestamped chapter markers calculated?+
Chapter markers are derived from structural dialogue transitions, subtitle cue boundaries, and significant topical pauses, formatted cleanly as [MM:SS] Chapter Title.
Can I copy the generated Markdown directly into my podcast host?+
Yes. The Show Notes tab provides a one-click 'Copy Markdown' button that copies clean, formatted Markdown ready to paste into Buzzsprout, Spotify for Podcasters, Libsyn, Apple Podcasts Connect, or YouTube video descriptions.
Are my podcast audio and transcripts kept private?+
Yes. Zero podcast audio or transcript text is ever uploaded to external cloud endpoints. All summary structuring occurs locally in your browser.
Can I export both show notes and edited audio together?+
Yes. You can download the lossless 16-bit WAV master audio and copy or export the Markdown show notes in the same workflow.
