Found a stale price, a model ID that's changed, a broken calculator, or a mistake in one of the error-and-fix pages? This goes straight to the person who runs the site, not a support queue, and we read every message.

Corrections matter more here than on most sites — every number on ClaudeHow is meant to be correct on the day you read it, and the fastest way we catch a figure that has drifted since our last check is a reader telling us. If you're not sure whether something is wrong or just unfamiliar, ask anyway.

Also welcome: a tool that's missing an input you need, a workflow the how-to guides don't cover yet, or a request to add a specific error message to the catalogue. We can't promise every request gets built, but we do read all of them, and the error catalogue in particular grows almost entirely from what readers report hitting in production.
