A document-to-podcast studio for when you need your own voice, editable scripts, more than two hosts, or longer episodes.
NotebookLM's audio overview is a great free starting point. It breaks down when you want your own voice, a different host count, an editable script, or a longer episode.
Clone a voice from a short sample instead of being stuck with the same two hosts.
Rewrite the outline and script at every step before audio is generated.
Run multi-speaker episodes with a catalog or cloned voices for each speaker.
Episode length is bounded by your credit balance, not a fixed minute limit.
Adjust speed, volume, and loudness before exporting audio.
Retry a failed segment without redoing the whole episode. Download anytime.

Review the AI-generated outline and script. Rewrite sections, adjust tone, and add direction tags.
Pick from the voice catalog, clone your own from a sample, or assign voices for a multi-speaker episode.

You can preview the document-to-podcast workflow for free. Paid plans start at $12/month and include 30,000 credits (about 35-40 minutes of finished audio). NotebookLM is free but locks the voice, host count, and script.
Yes. VocalVia supports voice cloning from a short audio sample. Upload a clip, save it as a custom voice, and use it for single-voice narration or as one of several speakers in a multi-voice episode.

Yes. Multi-speaker episodes support more than two voices, while NotebookLM is limited to two fixed hosts. You can assign different catalog or cloned voices to each speaker.
There is no hard length cap per episode. Episode length is bounded by your credit balance, not a fixed minute limit. Background synthesis runs as a step-based workflow so long episodes do not time out.
No. NotebookLM is a research tool with source-grounded chat across notebooks. VocalVia focuses on the generation side: turning a document into a polished, editable podcast. For cross-notebook Q&A, NotebookLM or a tool like Recall is a better fit.
