Running out does not lock you out. Nothing is deleted and nothing is hidden.
What still works
Your Weekly brief. It never spends credits, so running out does not stop it.
Everything you have made. Chats, docs, Collections and creator lists stay readable.
Browsing. Videos, Formats and Creators all work, and the creators you follow keep updating.
What stops
Vamos answering you, in the app or through Connectors, and Routines running. A Routine that comes due with no credits does not run and says that was why, then tries again next time. You also get an email about it, at most once a day per workspace.
The three ways out
Wait for your reset. Plan credits refill every month and don't roll over. On a monthly plan that is your renewal date, shown in Settings, under Billing. If a payment is past due, the refill waits until it goes through. Free's 100 credits are one-time and never refill.
Buy a pack. Immediate, and pack credits sit in a separate balance the monthly reset does not touch. Packs are sold in Settings, under Billing, on a paid plan whose payments are up to date, so not on Free or during the trial.
Move up a plan. Pro has 2,000 credits a month and Business 6,000. On Free there is no other way out. During the trial, choosing a plan ends the trial early and starts the plan that day.
