When AI credits run out (in AI Copilot, Period Analysis, Rewrite with AI or another AI feature), a notice appears with the next step:

  • Free plan (trial): the View plans button takes you to the plans page. Subscribing to a plan unlocks the daily credit quota.
  • Paid plan: the Buy credits button opens the one-time credit packages. A package is only used after the plan's daily quota runs out, and it's valid for 12 months.

The plan's daily quota renews every day. Only the account owner can buy credits; team members need to ask the owner. In the iPhone app, purchases are made in the browser.
