You can invite new team members on the Teams page.


Voicemail summaries by AI

Each voicemail received in a supported language is analyzed by our AI. You will get the following additional information in the email with the recording.


  • What is the voicemail about and from whom?
    The email subject will tell you briefly what the message is about – and who it is from (if available).
  • Caller sentiment analysis
    We will show an emoticon indicating the mood of the caller; happy, neutral or angry. The emoticon will be in the subject of the email
  • Summary
    There will be a summary of the voicemail message in a few paragraphs.
  • Key points
    The key points in the voicemail will be delivered in a bulleted list.
  • Action expected
    If the caller expects you to do anything, we will make it clear what that is.
  • Transcription
    A word-by-word transcription of everything the caller said follows.

The email will have the actual recorded message as an attachment.

Major languages are supported. Other languages may not receive summaries.

We will try to find the name of the caller in your mobile contacts if you have provided us with access to them in our mobile apps. In the absence of that we’ll try to pick up the caller’s name from the message.
Voicemail summaries are included in our Paid plans. Free accounts get 1 000 free AI credits when signing up. This allows you to test the service for a while at no extra cost. Each Voicemail summary costs 10 AI credits.

Not receiving any voicemail?

If you are not receiving voicemails as expected, this may be caused by either of these reasons:

  • Deliveries ended up in your email spam inbox
    Our delivery may have ended up in your spam email inbox. Add to your safe senders list in your email program to be sure to receive voicemail.
