All plans include the core assistant, knowledge, chat customization, conversations, analytics, and experiments. The differences are the base fee, included bookings, overage rate, optimized-page allowance, and Darwin branding. Prices are USD before tax. Every plan requires a payment card during account setup.

Annual plans

Annual subscriptions save 20% on the base fee. The discounted base fee is charged upfront for the year; additional bookings are still billed monthly. Paid-plan included bookings reset each monthly billing cycle, including on annual subscriptions. Unused bookings do not roll over or become one annual pool. Origin has no annual base subscription.

The first five on Origin

Origin’s five free bookings are a one-time workspace allowance. They do not reset each month or when you switch plans. Paid-plan monthly allowances do not stack with an extra five Origin bookings.

Optimized pages

This allowance limits pages covered by Darwin’s optimization system. It is separate from the knowledge pages you import and from the number of visitors who can read a page.
