Finding bugs, security issues and performance problems in code can be difficult and time consuming, especially for beginners and students. Developers may also miss problems when they are working quickly or under deadlines. AI Code Reviewer provides a simple way to review code using Google Gemini. Users can paste their code or upload a supported file, select the programming language and start the review. The app checks the input first and only sends valid code for AI analysis. The review shows bugs, security, performance and code quality issues. It also provides a Code Health score, AI summary, Time Complexity, Space Complexity and optimization suggestions. Users can filter issues, copy the report and save the review for later. The main users are students, beginner developers and programmers who want quick feedback on their code. The interface is designed to keep the results easy to read and understand. What makes the project different is that it brings code review, complexity analysis and review history together in one simple tool. It also checks the selected language before using the AI which helps avoid unnecessary API requests. By combining input validation, AI analysis and saved review history. The project gives users a quick way to find problems in their code and understand how they can improve it.
