What happens when I exceed my chat quota?

Last updated: September 21, 2026

When your chat volume exceeds the plan limit

Short version: your account is never locked and there are no extra charges. Once the AI quota is used up, the bot pauses and your team takes over. Once the conversation quota is used up, new visitors see a contact form instead of the chat.

Two AI limits, not one

Your plan names a number of AI conversations per month. Because a single conversation can run arbitrarily long, a fair-use budget also caps the total volume. The bot pauses as soon as either limit is reached — which one comes first depends on how long your conversations run.

LimitWhat it countsWhen it applies
AI conversationsdistinct conversations with a bot replywith very many short conversations
Fair usetotal AI usage in the monthwith few, very long conversations

The fair-use budget is sized so that it does not apply to conversations of typical length. Importing your knowledge base also counts towards it, not only the chats. The rule is in section 4(4) of our terms.

Thresholds + behaviour

UsageWhat happens
80%Notice under Analytics → Usage, email to the workspace owner
100%Bot pauses, every conversation goes straight to agents, second email
new monthBot switches back on automatically

Both AI limits share these thresholds. The email says which of the two applies.

What keeps running while the AI pauses

  • Live chat between visitor and agent: yes, as long as the conversation quota lasts (see below)
  • Email channel: yes
  • Tickets: yes
  • Knowledge base: yes
  • Webhooks: yes
  • AI chatbot: no — paused until upgrade or the next billing period

The conversation quota

Independent of the AI, your plan caps the number of conversations per month — with or without the bot. Once it is used up:

WhoWhat happens
new visitorssee a contact form instead of the chat; the request reaches you by email and uses no quota
visitors with an ongoing conversationkeep writing as usual — messages in existing conversations do not count
new monthnew visitors can chat again

There is no advance email warning for the conversation quota.

Upgrade any time

Settings → Billing → "Change plan". Prorated, takes effect immediately. You can also upgrade temporarily and step back down later.
