How to add it
- Notion: type
/embed, paste the link, press Embed link. Drag the corner to resize. - Websites and blogs (WordPress, Google Sites, Wix, Squarespace): add an HTML or embed block and paste the code.
- OBS and streaming: add a Browser source with the link and set width 720, height 640.
- Canva: Canva only embeds sites it supports. If pasting the link does not show the timer, add the link to a button or text instead.
- Google Slides and PowerPoint: slides cannot run a live widget. Put the link on a shape or text and click it during the lesson.
Other languages
Add a language prefix to the address, for example /ko/embed/…, /ja/embed/… or /es/embed/….
Rules
- The code includes one small Lifespan Lab link. You may remove it, but we appreciate it.
- Do not put the widget inside pages with illegal or adult content.
