AI Credits
Every time your AI agents interact with a visitor — whether through chat or voice calls — it consumes AI credits. Credits are the currency that powers your AI features, and understanding how they work helps you manage your usage effectively.
What AI Credits Are
AI credits are units that measure your AI usage. Each AI interaction costs a certain number of credits. Your subscription plan includes a set number of credits each billing cycle, and you can purchase additional credits if you need more.
Think of credits like minutes on a phone plan — you have a monthly allowance, and each conversation uses some of that allowance.
How Credits Are Consumed
Different types of AI interactions consume credits at different rates:
- Per chat message — Each message your AI Chat Agent sends in a conversation uses a small number of credits. Short conversations use fewer credits; longer back-and-forth exchanges use more.
- Per call minute — Each minute of an AI voice call consumes credits. Voice calls typically use more credits per minute than chat messages because of the additional processing involved in speech recognition and text-to-speech.
Credits are only consumed when your AI agents respond. If a visitor sends a message but the AI does not reply (for example, because the conversation was immediately handed off to a human), no AI credits are used for that interaction.
Viewing Credit Usage
To see how your credits are being used, go to Packages > AI Credits. This page gives you a complete picture of your AI consumption.
Donut Gauge
At the top of the page, a donut gauge shows your usage at a glance. The gauge visually represents what percentage of your credits you have used so far in the current billing cycle. This makes it easy to see whether you are on track or running low.
Credit Stats
Below the gauge, you will find key stats:
| Stat | What It Shows |
|---|---|
| Package Credits | The total number of credits included in your current plan |
| Consumed | How many credits you have used so far this cycle |
| Remaining | How many credits you have left |
| Purchased | Any additional credits you have bought on top of your plan |
These numbers update in real time as your AI agents handle conversations.
Check your credit stats regularly, especially if you are running the Auto-Connect Agent, which proactively starts conversations and can increase your credit consumption.
Per-Model Breakdown
The AI Credits page also shows a breakdown of credit usage by AI model. If your agents use different models (configured in the Chat Agent or Call Agent settings), you can see how many credits each model has consumed.
This helps you understand which models are using the most credits and whether switching to a different model might be more cost-effective for your needs.
Activity Log
The activity log provides a detailed record of every AI interaction that consumed credits. Each entry includes:
- Timestamp — When the interaction happened
- Type — Whether it was a chat message or a voice call
- Credits used — How many credits that specific interaction consumed
- Details — Additional context about the interaction
Date Filters
You can filter the activity log by time period to focus on the data that matters most:
- 7 days — See usage from the past week
- 30 days — See usage from the past month
- 90 days — See usage from the past quarter
- All — See your complete usage history
Use the 7-day filter to spot trends in your daily AI usage. If you notice a sudden spike, check whether a new page rule or Auto-Connect trigger is driving more conversations than expected.
Purchasing Additional Credits
If you run out of credits before your billing cycle ends, you can purchase additional credits directly from the AI Credits page.
- Go to Packages > AI Credits
- Click Purchase Credits (or the equivalent button)
- Select the number of additional credits you want
- Complete the purchase
- The new credits are added to your account immediately
Purchased credits are added on top of your plan credits and are shown separately in the Purchased stat so you can track them.
If your credits run out and you have not purchased additional ones, your AI agents will stop responding to visitors. Make sure you monitor your usage and purchase more credits before you hit zero, or consider upgrading your plan if you consistently need more.
Managing Credit Consumption
Here are some strategies to make the most of your AI credits:
- Optimize your Knowledge Base — A well-trained Knowledge Base helps your AI give accurate answers faster, which can reduce the number of back-and-forth messages per conversation.
- Set call duration limits — Configure maximum call lengths in your Call Agent settings to prevent unexpectedly long calls from consuming too many credits.
- Tune your Auto-Connect thresholds — If the Auto-Connect Agent is using a lot of credits, consider raising the lead score threshold so it only reaches out to the most qualified visitors.
- Review and refine — Regularly check your activity log and per-model breakdown to identify areas where you can reduce unnecessary usage.
