Each reply from your AI Agent uses one message credit.

Your message limit resets on the first of every calendar month, regardless of when you subscribed. If you sign up on June 15th, your messages reset on July 1st.

ChatSpark counts approximately 750 words as one page across all training data types. A typical PDF page, website article, or document section falls well within this range. Basic, Plus, and Pro page limits apply per AI Agent. Enterprise uses a bespoke allowance shared across the account.

Each AI Agent is dedicated to one communication channel: your website, WhatsApp, Instagram, Facebook Messenger, Telegram, or Slack. To deploy across multiple channels, add a plan for each one. You can hold as many plans as you need under one account, and all your AI Agents are managed from the same dashboard. Limits stack across plans.

Yes. Every plan you add stacks its limits on top of your existing totals. More messages, more pages, more AI Actions. There is no cap on how many plans you can hold. If you find yourself managing four or more Pro plans, contact us about Enterprise for bespoke limits.

Yes, the Unbranded ChatSpark Widget is available in our Pro and Enterprise plans.

Yes. Choosing annual billing saves you 14% compared to paying month to month. That works out to nearly two months free over the course of a year.

We do not offer refunds. Because AI Agents are trained and infrastructure is provisioned from the moment you sign up, we are unable to reverse those costs. If you are unsure, we recommend starting with our 14-day free trial on the Basic plan before committing to a paid plan.

Yes, with an Enterprise plan. Any agent you have already created can be selected in the AI CoPilot browser extension to answer questions from your knowledge base while you work in Gmail, Zendesk, or another browser tab. For internal team use, we recommend a dedicated agent using the CoPilot Agent Type. It removes customer-facing settings and unlocks CoPilot Analytics. Creating a dedicated CoPilot agent requires an additional plan slot.
