About Simplebooklet
Simplebooklet is rebuilding its core around true HTML rendering and built-in AI agents.
Simplebooklet ships a monthly feature drop and is in a substantive build phase. Two structural moves stand out: rebuilding the page-conversion engine to render true HTML/CSS instead of page screenshots, and adding a built-in set of AI agents that act on a user's content. Around them sit steady additions — BrandKit for automatic brand consistency, message popups, and expanded account limits.
