Synthia AI
Overview
AI-powered GitHub intelligence platform with RAG-based codebase analysis.
Synthia AI is a production-grade AI code review and repository intelligence platform built using Next.js and LangChain.js. It automates commit summaries, repository understanding, and missed meeting transcription analysis using Gemini and AssemblyAI. Designed for multi-tenant teams, it integrates GitHub APIs and implements credit-based billing.
The Challenge
Developers spend excessive time reviewing commits, understanding large repositories, and catching up on missed meetings. Teams needed an AI assistant that understands code context deeply.
Obstacles Faced
Handling large repository context efficiently
Designing multi-tenant architecture
Reducing LLM hallucination in code analysis
Implementing secure GitHub integration
Feature Engine
- Built a RAG pipeline using LangChain.js
