Question: Can you recommend a service that provides AI-assisted feedback on coding projects and exercises?

One of the highest-recommended options is CodeRabbit. It's an AI-powered service that offers context-aware feedback on pull requests and integrates with GitHub and GitLab. Features include line-by-line code suggestions, real-time chat and customizable reviews. It's designed to speed up code review so developers can spend more time on higher-level work, and it's a good option for improving coding productivity and reducing bugs.

Another strong contender is GitHub Copilot. The tool offers context-aware help in the development process, with features like code completion, natural language prompts to code and chat help to ask questions about codebases. It works with a variety of IDEs and terminals and is designed to help developers work faster and avoid security problems, so it's good for solo developers and businesses.

If you want a more specialized service, CodeReviewBot uses advanced AI algorithms to review code, raise flags about problems and offer detailed explanations. It works with GitHub and offers a variety of pricing tiers, so it's good for teams of a few or a few hundred. Its use of GPT-4 and Gemini AI models means it can offer detailed, authoritative feedback, and it can help teams focus on higher-level coding work.

Korbit is another interesting option, automating code reviews for GitHub pull requests and offering immediate feedback to improve code. It offers a management dashboard with code quality metrics and developer performance tracking, so it's good for teams that want to improve their code review process while keeping data private.
