About RepoBox

Building the Zero-Cloud Context Suite for the AI Engineering Era

RepoBox was born from a fundamental frustration: developers spend hours copying files, struggling with context window limits, and worrying about proprietary code leaks on cloud proxy servers. We engineered a better way.

The Four Architectural Pillars of RepoBox

How we engineered the fastest, most private context generation platform.

1. Local-First Sandbox Privacy

We refuse to route user source code through remote backend proxies. When you decompress a 50MB monorepo or 100-page PDF, the entire pipeline executes locally in your browser's Web Workers. Your company's IP stays strictly on your machine.

2. AST & Heuristic Bloat Filtration

Real-world repositories are 80%+ noise: build artifacts (dist/, .next/), package locks (package-lock.json), source maps, and binary assets. RepoBox automatically purges this bloat to save you thousands of dollars in AI API tokens.

3. Multi-Modal Context Ingestion

Developers don't just work with code files. You need official documentation (Web2Txt) and specification documents (File2Txt PDF/Word/Excel). RepoBox unifies all context streams under one cohesive interface.

4. Frontier Model Calibration

RepoBox includes live token estimation and cost calculators mathematically calibrated for Claude, ChatGPT, Gemini, and DeepSeek R1. Know your exact prompt budget before submitting.
