Add-ons
Learn how to purchase and manage add-ons to increase your message credits and storage capacity beyond your plan limits.
Add-ons let you increase your message credits or storage capacity without upgrading to a higher plan. If you're happy with your current plan but occasionally need more messages or storage, add-ons are the perfect solution.
Plan Requirement: Add-ons are available on paid plans only (Basic, Essential, and Business). Free plan users must upgrade to a paid plan before purchasing add-ons.
What Are Add-ons?
Add-ons are optional extras that boost your plan limits:
Extra Message Credits
Additional AI-generated messages per month
+1,000 messages
Extra Storage Capacity
Additional character storage for your knowledge base
+5 million characters
You can purchase up to 10 units of each add-on type.
Example
You're on the Essential Plan (2,000 messages/month, 20M characters storage). During a busy month, you expect 3,500 messages. Instead of upgrading to Business, you purchase 2 units of Extra Message Credits (+2,000 messages), giving you 4,000 total messages for that month.
How to Purchase an Add-on
Log into your AI Bot Kit dashboard.
In the left sidebar, go to Plans & Billing.
Scroll to the Add-ons section.
Choose the add-on you want:
Extra Message Credits — select how many units (1–10).
Extra Storage Capacity — select how many units (1–10).
Click Purchase Add-on.
Confirm the payment. The add-on is added to your existing subscription instantly.
Pricing
Add-on prices are shown in your dashboard and depend on your billing interval:
Extra Message Credits (per 1,000 messages)
Varies
Varies
Extra Storage Capacity (per 5M characters)
Varies
Varies
If you pay yearly for your main plan, add-ons are also billed yearly at a discounted rate.
How Billing Works
Same billing cycle — Add-ons are added to your existing Stripe subscription. They renew on the same date as your main plan.
Prorated charges — If you add an add-on mid-cycle, you only pay for the remaining days in your current billing period.
Prorated refunds — If you cancel an add-on mid-cycle, a prorated credit is applied to your account.
Managing Your Add-ons
View Active Add-ons
In Plans & Billing → Add-ons, you'll see:
Which add-ons are currently active
How many units you have
Your new total limits (plan limit + add-on bonus)
Cancel an Add-on
Go to Plans & Billing → Add-ons.
Find the active add-on you want to remove.
Click Cancel.
Confirm the cancellation.
Your add-on stays active until the end of your current billing period, then stops renewing. A prorated credit is applied if you cancel mid-cycle.
Tips for Using Add-ons
Use add-ons for temporary spikes. If you only need extra capacity for a month or two, add-ons are cheaper than upgrading your plan.
Monitor your usage. Check your message and storage usage regularly in the dashboard to decide if add-ons make sense.
Combine add-ons. You can have both message and storage add-ons active at the same time.
Yearly is cheaper. If you know you'll need extra capacity long-term, paying yearly saves money.
Troubleshooting

My add-on purchase failed
Make sure your payment method on file is up to date.

I canceled an add-on but my limits haven't changed
Canceled add-ons remain active until the end of your current billing period. Your limits will adjust on your next renewal date.
