AI Assistant fees are determined by the total number of credits applied to messages sent in a rolling 30-day period across all your AI Assistants in all environments. Each AI message equals one user question answered by the AI Assistant, which leverages your connected documents or website. Every plan includes a monthly credit limit that can be used to consume messages at a rate of 2 messages per credit when using the latest AI model (GPT-4o). Additional 500-credit bundles are available for $80/month (annual billing) or $100/month (monthly billing). See pricing details.
A global limit is associated with your account, specifying the maximum number of credits used over the rolling 30-day period. Usage is calculated on a rolling 30-day period across all of your AI Assistants. Your current usage is displayed at the top of the AI assistant page, allowing you to monitor usage and increase your limit as needed to avoid reaching the cap that would disable all AI Assistants and associated UI functionality. Note that this is different than setting and managing assistant-level limits, which are managed at an individual AI Assistant basis.
Assistant-level limits vs. Global limits
Assistant-level limits help you manage individual deployments, but don't prevent overall usage from growing.
Global limits act as a safety net, completely stopping AI Assistant-related usage when reached to prevent unexpected billing or auto-upgrades.
Usage calculations for both assistant-level and global limits are assessed on a rolling 30-day period. If an assistant or related functionality is deactivated when a limit is reached, it will be restored after 24 hours when the 30-day calculation resets.

Managing your global limit
Use global limits to prevent your AI assistants from incurring overages that lead to automatic upgrades. When the global limit is reached, all your AI Assistants and associated assistant functionality in the Userflow UI (e.g., test chats, staging environments, etc.) will be disabled for a 24-hour period. After this period, functionality will resume.
Userflow automatically sends you email notifications (warnings) when usage reaches 90% of the limit you’ve set, allowing you time to assess usage. If you exceed your limit (which is assessed company-wide across all of your AI Assistants), one of two results may occur:
You will be auto-upgraded, or
Your AI Assistants will be removed from all environments due to reaching your global limit, if one is set.
In either case, you will receive an email notification with details. Learn more in the AI Assistant usage notifications documentation.
Manage your global limit:
Select AI Assistant from the sidebar.
Click Manage global limit.

Managing AI Assistant-level limits
Allocate subscription capacity and mitigate potential abuse by setting credit limits (per user per day and per rolling 30-day period across all users) for each individual AI Assistant.
To set maximum credit limits in the assistant settings. For more details, refer to the AI Assistant settings and advanced customizations documentation.
Maximum messages per month for an Environment (across all users)

Default: Unlimited
Custom limit: Set a limit to control usage
Usage is assessed on a rolling 30-day period. It’s possible for usage to exceed the set limits between such checks. Please be aware of potential overages and their implications as explained above.
When the limit is reached:
The assistant will be hidden from your Resource Center until the limit is expanded after 24 hours.
The account owner will receive an email notification when the assistant is disabled.
There may be a brief delay (up to 10 minutes) in both hiding the assistant after reaching the limit and restoring visibility at the beginning of the new cycle.
Test messages are subject to your usage limits. Any overages will incur additional charges.
The limit applies to messages sent to the assistant while previewing a resource center.
Maximum credits per user per day

Default: 200
Max: 1,200
The number of messages a user sends to the assistant is tracked over the last 24-hour period to determine when to enforce the limit.
When the limit is reached, the user cannot submit new messages. They will receive a response indicating that they’ve reached their daily limit.
Maximum input length
Default: Unlimited
You can limit the number of characters users can enter in the search query to improve search performance and efficiency and prevent potential abuse.
Ensure your latest assistant message limits are published.
Privacy Assurance and AI Assistant
Userflow does not use AI inputs to train, fine-tune, or otherwise improve public large language models. However, to maintain the highest standards of data security, we strongly recommend training your AI Assistant on non-sensitive data and instructing users not to submit any sensitive or private information in their AI Assistant searches. Refer to our Terms of Service for additional details.
