There are four kinds of Canvas you can publish, plus one you import.
Writing
Essays, articles, short fiction, anything text-based. Viewers can leave Echoes on individual paragraphs. See Writing Canvases.
ZIP
The platform's audio-and-video format. ZIP Canvases have a waveform (or video timeline), optional transcript, and interactive event support — clickable moments, image swaps, slide-style sync. Best for podcasts, video essays, talks. See ZIP Canvases.
Ebook
Upload an EPUB and Zayvay splits it into chapters. Viewers read in a paginated reader on your Vault. See Ebook upload.
Video
Plain video — no timeline interactivity, just a clean player. Upload from Forge; Zayvay encodes to HLS. See Video Canvases.
RSS-imported show (special)
If you already host a podcast elsewhere, you can mirror its RSS feed into Zayvay. Your audio stays on your existing host; Zayvay handles the listening experience, transcripts, and Echoes. See Importing from RSS.
You can mix any of these on one Vault. Most creators do.
