Presenter Mode



  • Show your slide note
  • Set a timer
  • Record your actions and voice, and do time-travel
  • Draw lines on the slide

Recording Your Actions

Video -> Recording Your Voice

Drawing Lines

When you write characters on the host side, it will be reflected on the client side in real time.

Live Mode


Fusuma can fetch tweets from Twitter. In addition, fusuma have an api endpoint.
If you specify a keyword and authentication keys, fetching from twitter will be enabled.
Since comments can be sent to fusuma itself, you can use in the private case.
Also, this mode can run with Presenter Mode.


This slide is very simple, so this is a measure of the maximum performance fusuma can deliver.

The values of Accessibility and Best Practices depend on the user because the user writes HTML(Markdown).
If you want to make SEO score 100%, you should fill in the .fusumarc.yml.
