PromptMap is a .NET console application that scans a Visual Studio .sln file (or a directory of .cs files) and generates a structured map of your solution — files, namespaces, classes, methods, and properties.
The generated text is designed to be AI-friendly, so you can paste it into ChatGPT (or any other coding assistant) to give it detailed context about your project before asking questions.
- Parse .sln or directory recursively
- Map namespaces, classes, methods, and properties
- Options to include private members and constructors
- Output to a file or standard output
- AI-friendly format for better ChatGPT coding assistance
- Runs locally — no external services
You can clone and build PromptMap yourself:
git clone https://github.com/christopherdkeith/PromptMap.git
cd PromptMap
dotnet build
promptmap --solution <path-to.sln> [options]
promptmap --dir <path-to-directory> [options]
| --solution <path> | Path to .sln file |
| --dir <path> | Path to directory to scan |
| --out <path> | Output file path (default: stdout) |
| --include-private | Include private members |
| --include-ctors | Include constructors |
| -h, --help | Show help |
Here’s PromptMap mapping itself:

When using ChatGPT (or any AI assistant) to work with your project, context matters. Instead of pasting individual files or trying to describe your project structure manually, PromptMap gives the AI a full structural overview in one compact, readable format.
