What is chatgptregister?

ChatRegister is a Chrome sidebar extension built to handle ChatGPT and OpenAI account registration, authorization, Plus subscription payment, and platform sign-in steps in bulk, rather than one account at a time by hand. The README describes it as a tool for automating registration, verification codes, OAuth logins, Plus payments, account importing, retrying failed steps, and keeping records of what was done, all inside one extension instead of a single one-off script. Access to the tool is controlled through activation codes called CDKs. A user pastes a CDK into the extension's activation field and clicks activate, after which the extension runs without the limits that apply to an unactivated free tier. Each CDK is described as single use and tied to one device, and the README warns that sharing a CDK with another device or reusing one that has already been redeemed will cause the activation to fail. Beyond the extension itself, the README also lays out a plan for a separate backend service called Sub2API, which is meant to track a pool of accounts and expose a read-only web endpoint reporting how many of those accounts are currently available to use, meaning not rate limited or in a cooldown period. That plan describes running a small Python service behind Nginx, protecting it with basic authentication checked against the existing Sub2API login system, and caching results briefly to avoid hitting the database on every request. Because this tool automates the creation and management of accounts on someone else's platform at scale, and is distributed and monetized through paid activation codes, anyone considering it should think carefully about whether that kind of bulk account automation is allowed under the terms of service of the platforms it targets.
