Code Sage AI
AI-powered code review tool using Gemini API with real-time bug detection and improvement suggestions.
Tech Stack
Overview
Code Sage AI is an automated code analysis tool that provides developers with instant, AI-powered feedback on their code. Built with the Google Gemini API and a Convex real-time database, it identifies bugs, suggests improvements, and helps developers write cleaner code.
The Problem
Manual code review is time-consuming and inconsistent. Junior developers often wait hours or days for feedback on pull requests, slowing their learning cycle.
The Solution
An AI-powered code review tool that provides instant feedback. Paste your code, select a language, and get detailed analysis within seconds — including bug detection, performance suggestions, and best practice recommendations.
Key Features
- Real-time code analysis powered by Google Gemini API
- Bug detection with severity levels and fix suggestions
- Code improvement recommendations with before/after examples
- Persistent review history using Convex real-time database
- Syntax highlighting for 20+ programming languages
Technical Decisions
Why Convex over a traditional database? Convex provides real-time subscriptions out of the box. When a review completes, the UI updates instantly without polling — critical for a tool where users expect immediate feedback.
Why Gemini over OpenAI? At the time of building, Gemini offered a more generous free tier and strong performance on code analysis tasks, making it ideal for a project that needed to be demo-friendly.
