CP : All in One

Find contests, add Google Calendar reminders, back up accepted solutions to GitHub, and save problem notes.

CP : All in One — Contests. Solutions. Notes. Keep your competitive programming practice organized. Browse upcoming contests, search the schedule, and filter events to match your interests. Connect Google Calendar to add contest reminders, update synced events, and remove events managed by the extension. You can also add individual contests through calendar links. Connect GitHub and choose a private repository to back up captured accepted solutions from supported submission pages. Files are organized by platform, language, and problem. Temporary failures are retried, and contest submissions wait until the recorded contest end time. Past submissions are not automatically collected; a manual history import is available for one supported platform. Save ideas, approaches, and edge cases beside supported problem pages, including contest questions. Notes remain local to your Chrome profile and can be reopened on the same question. They are not uploaded with solution backups. Google and GitHub connections are optional. Chrome must be running for scheduled background tasks. Platform support varies by feature and depends on current website layouts. See the project documentation for feature-specific support. This extension is independent of the programming platforms it supports.
