New features

- Build lessons with the redesigned course editor: The course editor has a rebuilt layout system with cards, slices, and columns, cleaner on-hover controls, and drag-and-drop to rearrange your content. The same layout carries through to published and SCORM courses.

- The full Google Fonts library, with search: Brand theme and editor font pickers now offer the entire Google Fonts catalog through a searchable picker with live previews. Your chosen fonts carry through to PDF, PPTX, and SCORM exports.

- A course agenda on your cover page: Cover pages can now show a table of contents listing each lesson with its reading time and the total course time. It is on by default and can be toggled off in the cover page editor.

Bug fixes

- No more errors on an empty objectives field: Fixed a bug where an empty lesson objectives list could break, causing errors when pressing Enter, Backspace, or Select All.

- Invalid learning outcomes are caught sooner: An over-length learning outcome is now flagged before you move to the next step, instead of silently failing at the end of course generation.

- Clearer errors for lessons missing source pages: Page-based lessons with no assigned source pages now fail fast with a clear reason, instead of retrying and erroring at the very end.

Improvements

- More natural narration with Gemini 3.1 voices: Course narration now uses Google's Gemini 3.1 text-to-speech, with a curated set of natural-sounding voices and better multilingual pronunciation. If you already picked a voice, it stays the same.

- A refreshed course navigation sidebar: The navigation sidebar has a lighter, clearer look across both the learner viewer and the editor, with clearer lesson and progress indicators.

- A cleaner course editor toolbar: The editor now has a slimmer top bar and floating tool rails for AI, elements, comments, audio, themes, and translation, plus a desktop and mobile preview toggle.

- A refreshed course library: The library has a refreshed design with a new workspace switcher, redesigned folder tabs you can drag to reorder, and compact course cards.

- Faster, restyled tooltips: Tooltips have been restyled to match the current design and now appear instantly on hover instead of after a delay.
