SIMO for Zoom documentation

Current setup and use guide for the SIMO Zoom app: install or open SIMO in Zoom, enter a room code, connect the Zoom listener, and use captions or translated audio.

Zoom app flow

Use this sequence when reviewing or using SIMO inside a live Zoom meeting.

Install or open SIMO

  1. Install SIMO from the Zoom App Marketplace listing if it has not already been added.
  2. Start or join the Zoom meeting where SIMO will be used.
  3. Open the Zoom Apps panel and launch SIMO.
  4. Approve Zoom prompts for the permissions requested by the app.

Join a SIMO room

  1. Enter the SIMO room code supplied by the host or organizer.
  2. Choose the caption language for the Zoom listener.
  3. Select Join.
  4. SIMO validates the active Zoom meeting context and binds it to the SIMO room.

Use captions and audio

  1. Wait for SIMO to prepare the Zoom listener surface.
  2. Select Connect to receive live captions.
  3. Select Enable audio to allow in-panel translated speech playback.
  4. Select URL if you prefer the external browser listener page.

Remove SIMO

  1. In Zoom Marketplace, go to Manage -> Added Apps.
  2. Locate SIMO and choose Remove.
  3. After Zoom sends the deauthorization event, SIMO stops active Zoom session state and completes the required data-compliance callback.
  4. Current production behavior does not create a durable transcript archive.

Host checklist

Confirm these items before escalating a meeting issue.

  • The host is running SIMO from the Zoom Apps panel inside the active meeting.
  • The listener is using the correct SIMO listener room code, not a speaker or admin code.
  • Zoom meeting-content sharing is enabled for apps when Zoom prompts for access.
  • The selected listener language is different from the spoken source language when translated audio is expected.

Public routes

These pages have different jobs, which is why opening one directly can feel different from opening it inside Zoom.

/zoom

Zoom App launch URL. Use it inside the Zoom client. In a normal browser, it shows setup guidance because Zoom meeting context is not available.

/zoom-listener

Zoom listener surface for captions, language selection, and optional translated audio. It accepts a room code as ?room=....

/support

Support, room-code listener join, issue contact form, and common troubleshooting for SIMO for Zoom.

/privacy /terms

Public policy pages for Marketplace review, organizers, hosts, and participants.

Troubleshooting

Most live issues are access, Zoom context, listener connection, or audio permission problems.

SIMO says the Zoom SDK is unavailable.

You are probably viewing the Zoom launch URL in a normal browser. Open SIMO from the Zoom Apps panel inside a Zoom meeting, or use the support page for setup and review links.

Captions do not appear.

Confirm the room code was accepted, the Zoom listener is connected, and Zoom meeting-content sharing has been approved for apps.

Translated audio is silent.

Select Enable audio, confirm browser playback is allowed, check device volume, and make sure the selected language is not the same language family as the spoken floor.

The external listener page is preferred.

Use the URL control from the Zoom listener, or go to /zoom-listener with the room code provided by the host.
