The agent-driven builder is real; the beta train fixing it is still running.
Oxygen spent the 6.2 cycle opening its object model to outside AI agents, and is now four betas deep into stabilising it. The headline capability — an agent creating and editing pages, templates, Components, selectors, variables and site settings — shipped in July and has not changed since; everything after it has been correction. Beta 3 added the other substantive item of the cycle, localisation, ending the requirement to build in English.
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.

The release rhythm has settled into long beta trains punctuated by one directional release, and 6.2's beta run is now longer than 6.1's was. Fix areas named in the latest beta — builder, Gutenberg, MCP server — show where the agent integration is costing stability: the MCP surface is being debugged in public alongside the ordinary builder regressions. Localisation arriving mid-beta rather than at 6.2's announcement suggests scope is still being added to the train.
With Beta 4 listing fixes rather than features, an RC is the next expected step before 6.2 goes final. Whether the MCP server keeps appearing in bug-fix lists is the thing to watch — it is the part of 6.2 with no prior release history to lean on.

Around them sit steady additions — BrandKit for automatic brand consistency, message popups, and expanded account limits.
The product is moving from a flipbook viewer toward a content platform: real HTML rendering improves quality and developer-grade fidelity, while AI agents and BrandKit reduce the manual setup that previously gated its features. The framing around a 'Reader's Journey' suggests engagement and conversion analytics are the throughline.
Expect the next drops to extend the AI agents into more content tasks and to build on the new HTML rendering with richer interactivity, alongside continued monthly cadence.
