Seeing is believing and reading is understanding. We made sure Organizers, Speakers and attendees are aware of how to both see the presentations and get into the context following the closed captions.

Currently, there are multiple ways of presenting with captions during the event on Hopin.

Captions for speakers on Backstage or Sessions

Individual speakers can use the Web Captioner tool for Backstage or Sessions and simply screen share the captions.

  1. Once the Speaker is on the Backstage or Session, click the screen share button, choose Web Captioner page on the Chrome tab and hit Share to start sharing the tab.

2. Open the Web Captioner page and click Start Captioning button at the bottom right corner of the page.

3. Return to the Session or Backstage of your event and start talking as you normally would. The captions will automatically appear on screen.

While on a Session (the Stage is adjusted automatically) with multiple Speakers double-clicking the screen shared area will make the text bigger and easier to read.

Tip: Check Web Captioner Help Center for more information and settings.

Captions for speakers over RTMP

While streaming via RTMP in OBS, the Web Captioner tool can be overlayed on top of the streaming area.

On the Sources menu at the bottom of the OBS app click the + icon and choose Window Capture option from the list.

Set the Window Capture a descriptive name (e.g. Captions) and choose the browser tab with Web Captioner on.

That’s it, your captions are now on RTMP and you can start streaming whenever you are ready.

Tip: Check OBS Help Center for more information and settings.

Captions for speakers with Google Slides

While presenting the Google Slides, Speakers can enable the captions feature inside the Slides and enjoy the captioning.

  • Open your presentation on the Google Slides page
  • Click the arrow button next to the Present button
  • Choose Presenter view
  • On the Presenter View screen hover over the bottom of the page and click the Captions button
  • Start speaking and the captions will appear automatically

Tip: Check Google Slides captions help page for more information and settings.

Captions for multiple speakers

With multiple speakers talking at the same time we recommend the following workarounds:

Google Meet

  • Start a Google Meet call
  • Send the link to a call for speakers to join
  • Click Turn on captions on the Google Meet page
  • Live stream the video meeting via Google Meet or screen share the window of the Meeting over RTMP via OBS


Translations to different languages

Captions only allow attendees to follow the Speakers live. For interpretation of the event Stage keynote we recommend the following workarounds:

One Stage - unlimited Sessions

In case you have in-house interpreters for your event, all you need is to create Sessions at the event dashboard page and invite your interpreters to the language-related session.


  • Make sure to add a descriptive name (e.g. [Spanish] Keynote presentation) to each session that will be live in a different language.
  • Set the interpreter as the only person who can come on screen in a session to avoid attendees jumping on screen.
  • Have a dry run with interpreters to make sure they will come on screen and on time during the event.

Third-party apps for simultaneous interpretation

Successful event Organizers already used Interactio app for simultaneous interpretation and enjoyed the results. You can search for other options on the internet and make use of any third-party solution for interpretation services of your events.
