Create a book from chat: Artifacts library → Create. Your AI writes the document and you edit it on paper inside the chat. Tap a block to edit, use ✦ Revise to rewrite it, and there's a table of contents, rename, and copy/download (PDF/DOCX/TXT/MD). Document chips above the composer bring you back to it.

Publish a book: pick a cover (default, upload, or AI-generated with "Include me"), then review the title, AI-suggested description, access (Free / Subscriber / Private), one-time price, and audiobook + animation. The published screen shows render progress with stop/resume and share. Owners can Edit from the landing.

One-time purchases (à la carte): priced courses, services and books show "$10 one-time" and Buy runs Stripe checkout, then flip to "Purchased · Full access". Works on cards, the course and service pages, the book landing, the reader's locked chapter and the chat lock banner.

Follow on the post detail and video viewer headers, next to Subscribe, using the same follow list as the feed.

Improvements

Reader arrows and edge taps always curl the page now, even with Reduce Motion on. This intentionally differs from web.

Chat mute is now account-wide (synced with web), which also stops long document writes being cut short for muted creators.

New-artifact drafts are kept if you leave before the AI writes, so the chip still brings you back. This intentionally differs from web.

Removed the chat button from the document editor.
