Plus PP Helper is a Chrome browser extension, written for Chrome's Manifest V3 system, that automates an account-creation routine inside CTF (capture-the-flag) competitions or other sandbox practice environments. The README is careful to say that the extension will refuse to run against the real chatgpt.com or OpenAI domains. It is built only for sandbox or mock copies of those flows. The core sequence is described step by step. The extension talks to a local mailbox API, asks it for an unregistered email address, opens the sandbox login page, fills the email in, polls the mailbox for the verification code, types that code back into the page, fills in a default name and age on the profile screen, then reads the sandbox session JSON, copies it to the clipboard, and finally opens a payment-link generator page and pastes the JSON in. To install it, the README says to open chrome://extensions, switch on developer mode, click Load unpacked, and select the project folder. A Side Panel then appears with the configuration form. Required values include the mailbox API URL and key, the mailbox web admin password (default admini123), the sandbox login page URL, and the session endpoint URL. A protection mode is on by default that restricts the session URL to localhost or matching sandbox hosts. The Side Panel also exposes seven manual buttons that run each stage of the flow on its own, useful when something gets stuck. A quick-abort button stops any in-progress run. Two mermaid sequence diagrams in the README show the message flow between the Side Panel, the background script, the mail UI, the sandbox login and session endpoints, the clipboard, and the payment page. The repository ships a GitHub Actions workflow that runs tests on every push and produces a packaged .zip and .crx of the extension as release artefacts. A repository secret called CRX_PRIVATE_KEY_B64 can be set to keep the extension ID stable across builds.
