Save on your chatbot costs with a better pricing model

When comparing virtual agent platforms, you should consider if they deliver what you need and what they really cost. With API-based pricing, usage fluctuations can lead to unpredictable costs and ever-growing charges. With Watson Assistant, you only pay by MAU (monthly active user) so even as interactions increase, you only pay for each unique user. As your interactions become more complex, your pricing is more predictable and can be much lower.

Frequently asked questions

What counts as a monthly active user (MAU)?

A user per month, or monthly active user (MAU), is any unique end-user who has one or more meaningful interactions with your assistant per calendar month across any integrations on a service instance (provided each user is tracked with the same identifier).

What qualifies as a meaningful interaction?

A meaningful interaction happens when an end-user sends a message to your assistant and receives a response. Welcome messages at the beginning of a new conversation are not charged.

How do I track MAUs for authenticated or known users?

If you’re using our REST API or web chat integrations, you need to provide us with a unique identifier (created by you) for each user that interacts with your assistant. We recommend a non-human identifiable database ID (such as a GUID) that doesn’t change throughout your customer lifecycle. If you’re using our Facebook, Slack or Intercom integrations, we pull the user ID from these sources automatically.

How do I track monthly active users (MAUs) for anonymous users?

If you’re using our REST API and you don’t have a userID because your user is anonymous, we recommend that you generate your own randomized IDs using something like UUID (link resides outside IBM).

If you’re using web chat and a user doesn’t have an identifier provided by you, we will generate one for your user and cookie them with the anonymous identifier in the event that they return to your site later in the month. That way you’ll only be charged once for that user.

What if an anonymous user logs in and becomes identifiable with a known ID? Are you going to charge me twice?

If messages are sent with two different userIDs then yes, you will be charged twice. We recommend either prompting users to log in prior to initiating a chat or using the anonymous value for that user throughout all of their sessions.

What if I don’t provide IBM with a userID for a given interaction?

We will charge based on the session identifier automatically, meaning that if this user returns a second time within the month after their session expires, they will be treated as two MAUs.

How many languages are supported?

Watson Assistant currently supports 13 languages and 1 in beta. However, support coverage differs from feature to feature. For a detailed view of the product’s support coverage by feature, go here.
