Usage limits
Usage limits are the caps an AI service puts on how much you can use it: messages per hours, file uploads, image generations, or access to the best models. They're the real difference between free and paid plans, and they reset on a rolling schedule.
Every plan of every AI service has a meter running somewhere. On a free tier you might get a batch of messages on the best model before being switched to a smaller one; paid plans raise the ceiling but still have one. Limits also apply to specific features (file uploads, image generation, voice, deep research) and on the API they take the form of rate limits and token budgets.
The frustrating part is timing. A plumber drafting quotes hits the cap mid-afternoon, exactly when the next customer email arrives, and has to wait for the rolling reset (often a few hours) or accept a weaker model. That’s not a malfunction; it’s the business model. Compute is expensive, and limits are how providers keep free and cheap plans sustainable.
Two practical notes. First, limits change often and are sometimes deliberately vague (“more usage”), so treat any number you read as a snapshot. Second, if you keep bumping into the ceiling, that’s data: it tells you which plan you actually need. Our plan picker matches current limits across vendors to how you really work.
