What is Oxygen?
Oxygen spent its 6.2 cycle turning the builder into something an AI agent can drive.
Oxygen ships on long beta trains: 6.1 ran four betas plus an RC before landing, and 6.2 is now three betas deep. The defining change in 6.2 is an agent interface — an external AI agent can create and edit pages, templates, headers and footers, Components, selectors, CSS variables, dynamic data, interactions, animations, and site settings. Beta 3 adds the builder's first non-English UI, ending an English-only history. Everything else in the current window is regression cleanup.
What is 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.

Oxygen
6.3DESIGN
Oxygen spent its 6.2 cycle turning the builder into something an AI agent can drive.
◆ Current state
Oxygen ships on long beta trains: 6.1 ran four betas plus an RC before landing, and 6.2 is now three betas deep. The defining change in 6.2 is an agent interface — an external AI agent can create and edit pages, templates, headers and footers, Components, selectors, CSS variables, dynamic data, interactions, animations, and site settings. Beta 3 adds the builder's first non-English UI, ending an English-only history. Everything else in the current window is regression cleanup.
◆ Where it's heading
The 6.1 cycle was breadth work aimed at the person in the canvas — multi-element selection, variable fonts, conditional classes, PHP 8.4 support. 6.2 changes the axis: rather than adding controls for a human to click, Oxygen is exposing the builder's object model so something else can write to it. Localization in Beta 3 pushes the same way, widening who can drive the builder rather than what it can draw. The cadence stays slow and fix-heavy, so the new surface will likely firm up before it grows.
◆ Prediction
Expect 6.2 to reach GA after another beta or RC dominated by agent-edit regressions, with the sibling Breakdance elements that ship alongside Oxygen 6 picking up the same agent-addressable surface.
Simplebooklet
2.5DESIGN
Simplebooklet is rebuilding its core around true HTML rendering and built-in AI agents.
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
