Open source · MIT
A command-line tool that uses AI language models to write shell commands, code, and answers.
The short answer
Choose Repomix if you need…
- Developers who want to ask an AI assistant questions about a whole project
- People preparing a codebase for an LLM with a limited context window who need token counts
- Teams that want to review or refactor code with an AI tool using one file as input
- Users who prefer not to install anything by running it with npx
Choose ShellGPT if you need…
- Developers who often forget shell or command-line syntax
- People who want AI answers piped in from files, logs, or git diffs
- Users comfortable with the terminal who have an OpenAI API key
- Anyone who wants to keep a multi-turn chat session from the command line

What each one is
Repomix
Repomix scans a project folder and combines all of its files into a single output file, such as XML, Markdown, or plain text. People use it to give an AI assistant like ChatGPT or Claude the full context of a codebase at once. It respects .gitignore files, can count tokens per file, and uses Secretlint to leave out files that look like they contain credentials.
ShellGPT
ShellGPT (the sgpt command) lets you ask an AI model questions straight from your terminal and get back shell commands, code snippets, or explanations. It can read input from pipes and files, so you can feed it things like a git diff or log output. People use it to avoid looking up command syntax online.
Best for

- People preparing a codebase for an LLM with a limited context window who need token counts
- Teams that want to review or refactor code with an AI tool using one file as input

- Users comfortable with the terminal who have an OpenAI API key
- Anyone who wants to keep a multi-turn chat session from the command line
Strengths
Repomix
- Simple to start: one command, and it can run without installation via npx
- Respects .gitignore, .ignore, and .repomixignore files and offers configurable include and exclude rules
- Provides token counts and multiple output formats (XML, Markdown, plain text)
ShellGPT
- Works from the terminal with pipes and redirection, fitting into existing workflows
- Supports Linux, macOS, and Windows, and the README says it works with common shells like Bash, Zsh, and PowerShell
- Open source under the MIT license with a large user base (about 12,000 stars)
Not ideal for
Repomix
- Projects that are too large to fit in an AI model's context window, since the single file may exceed it
- Anyone who needs guaranteed secret removal, because it relies on Secretlint pattern matching for known credential formats
- Non-technical users who are uncomfortable using a terminal, unless they use the website or browser extension instead
ShellGPT
- People who do not want to pay for OpenAI API usage, since the README says the default backend is paid and local models are not optimized for it
- Users who need a graphical interface, because it is a terminal tool
- People who will run shell commands without reading them first, since the tool offers to execute AI-generated commands
Trade-offs
Repomix
- A large repository packed into one file can exceed an AI model's context limit
- Secret detection depends on Secretlint's known formats, so it cannot guarantee that no sensitive data is included
- The README is truncated, so some setup details and options may be missing from this summary
ShellGPT
- Requires an OpenAI API key by default, and the README notes OpenAI API usage is not free
- The README states it is not optimized for local models and may not work as expected with them
- AI-generated shell commands can be wrong, so outputs need review before running
