Domains to Whitelist for Helperbird

A quick reference for IT admins showing which domains need to be whitelisted for Helperbird to work in your school or organization.

·

  • admin

If your school or organization uses a firewall, content filter, or proxy, you may need to whitelist certain domains for Helperbird to work properly. This guide lists everything your IT team needs.


Required Domains

These domains must be accessible for Helperbird to function:

Domains Helperbird needs, and what each one is used for.
DomainPurpose
helperbird.comMain website and help documentation
www.helperbird.comMain website
engine.helperbird.appHelperbird engine for subscription validation, subscription checks, and feature data

Email Domain

Helperbird sends emails from the following domain. If your email system has strict filtering, make sure this domain is allowed:

The domain used for account sign-in email.
DomainPurpose
helperbird.comSubscription emails, account notifications, and support replies

Emails will come from addresses like [email protected] and [email protected].


Optional Domains

These domains are used by specific Helperbird features and may need to be whitelisted depending on your setup:

Domains needed only by certain features.
DomainFeatureNotes
chrome.google.comChrome Web StoreNeeded to install or update the extension
microsoftedge.microsoft.comEdge Add-ons StoreNeeded for Edge installations
addons.mozilla.orgFirefox Add-onsNeeded for Firefox installations
*.cognitiveservices.azure.comImmersive ReaderUsed by the Immersive Reader feature
*.tts.speech.microsoft.comText to speech, natural voicesBlocking this leaves the free browser voices working and the Pro voices silent
*.stt.speech.microsoft.comVoice typingThe dictation stream. Blocking this stops voice typing with no error on screen
*.api.cognitive.microsoft.comAzure token exchangeUsed by both of the above

Two of these are easy to miss. Translation, Summarize, Simplify and the Screenshot Reader all go through engine.helperbird.app, not to Google or OpenAI directly, so that one host covers them. The Azure Speech hosts are separate: the region in the hostname is chosen at runtime, which is why they are listed with a wildcard. If they are blocked, the natural voices and voice typing fail quietly, with the feature appearing to do nothing.


How to Whitelist

The exact steps depend on your firewall or content filter. Here are the general steps:

  1. Log into your firewall, proxy, or content filter admin panel.
  2. Find the URL or domain whitelist/allow list section.
  3. Add the required domains listed above.
  4. Save your changes and test by visiting https://engine.helperbird.app from a managed device.

If you use Google Admin Console to manage web filtering, add these domains to your URL allow list under Devices > Chrome > Settings > Users & browsers > URL Blocking.


Troubleshooting

Helperbird is installed but not activating:

  • Make sure engine.helperbird.app is not blocked.
  • Check your proxy or SSL inspection settings. Some proxies can interfere with extension communication.

Emails from Helperbird are not arriving:

  • Check your spam or junk folder.
  • Make sure helperbird.com is allowed in your email filtering system.

Immersive Reader or Translation not working:

  • These features use third-party services (Microsoft Azure and Google Translate). Make sure the optional domains above are not blocked.

like 50 accessibility and product...

AMAZING app. I am a researcher and writer with learning and information processing challenges. The Helperbird app is like 50 accessibility and productivity apps in one. It has absolutely transformed my research process and experience to make it so much easier. No switching between multiple extensions.
