co provides scenario-based training for developers focused on code review, security, and AI code reasoning. The platform addresses skills that are often overlooked in traditional computer science programs, such as practical code review, handling security concerns, and evaluating AI-generated code. Its training is designed to help bridge the gap between junior developers and those who are ready for professional software engineering roles.

The platform offers interactive challenges where users review realistic scenarios, such as pull request reviews, identifying security bugs, or diagnosing issues in code. Users are prompted to flag suspicious lines, investigate problems, and explain their reasoning. After submitting their answers, participants receive a detailed debrief highlighting what they found, what they missed, and the significance of each issue in a production context. The scoring system emphasizes reasoning and problem-solving skills rather than just correct answers, aiming to develop critical thinking and pattern recognition in real-world development situations.

co covers a range of categories, with live modules available for Git and Gitflow, PII and security, code reasoning, and AI code review. Additional topics such as observability, debugging, code review etiquette, CI/CD, performance, incident ownership, and testing are planned for future release. The platform includes a free course titled "AI Code Review – The Missing Skill," which features hands-on scenarios involving reviewing outputs from tools like Copilot and AI agents. Users can access three scenarios per category for free without providing a credit card, and early access is available at no cost while the platform is in development. There is also a waitlist for a forthcoming Pro version, which will offer features like AI scoring, spaced repetition, and expanded content.

co is delivered as a web-based service and is developed by RoboticForce Inc. It is intended for developers seeking to improve their practical skills in code review and related areas, with a focus on preparing for real-world team environments and technical interviews. The platform positions itself as a training tool for professional developer skills not typically taught in academic settings.
