How do I convert a codebase or GitHub repo into a prompt for Claude or ChatGPT?

Upload your project folder or paste code files into the LLM Context Compiler. The tool automatically filters out binaries, lockfiles, and node_modules, formatting all files into a single, clean markdown context with real-time token count.

Is my source code uploaded to any server?

No. The entire process runs 100% client-side inside your browser. Your proprietary source code never leaves your local machine.

How does token estimation work for Claude and GPT-4?

The tool calculates approximate tokens based on standard BPE tokenizer ratios so you know whether your codebase fits comfortably into 128k (GPT-4o), 200k (Claude 3.5 Sonnet), or 1M/2M (Gemini 1.5) context windows.

Codebase to Prompt — Convert GitHub Repos & Code into AI-Ready Context

The LLM Context Compiler simplifies feeding full multi-file codebases and project directories into Large Language Models like ChatGPT, Claude 3.5 Sonnet, and Gemini 1.5 Pro. It automatically filters out non-essential assets (like node_modules, build artifacts, lockfiles, and binaries) and produces a clean, token-efficient markdown context bundle with real-time token estimation.

Why Developers Use LLM Context Compiler

Smart Noise Filtering

Automatically ignores heavy dependency trees, binary files, minified bundles, and SVG sprites to conserve prompt token limits.

Context Window Token Estimator

Calculates approximate token usage to ensure your codebase fits within 128k, 200k, or 1M context windows.

100% Client-Side Privacy

Your proprietary intellectual property and source code never leave your browser. Zero backend telemetry.

Pre-Built Prompt Templates

Inject structured instructions for Architecture Review, Bug Hunting, Test Generation, or Security Audits with one click.
