TalkToGitHub is an open source web tool that lets you chat with any public GitHub repository in plain language, turning a codebase into a conversation you can question instead of reading file by file.
About TalkToGitHub
What Is TalkToGitHub
TalkToGitHub is a web app that answers questions about a public GitHub repository in natural language. Point it at a repo, ask things like what the project does, how a feature is wired up, or how to run it, and it replies in a chat thread. The project is open source under the MIT license, and the hosted version runs at talktogithub.com.
The problem it targets is orientation. A repository is rarely unreadable; it is mostly unsorted. You need to know what the project does, where the important logic lives, and which files matter before you change anything. TalkToGitHub answers those questions directly instead of leaving you to hop between folders, README files, and issue threads.
The limits are worth knowing up front. It works with public repositories, and the roadmap still lists support for individual files and folders, local files, and repositories larger than about one million tokens as planned rather than shipped. The hosted app leans on a large language model under the hood, so answers depend on how well the project is documented and structured.
Getting Started
- Open talktogithub.com, or add the
talktoprefix to any GitHub repository URL. - Paste a public repository link and let the tool read the codebase.
- Ask a question in plain language, such as what the project does or how authentication works.
- Read the answer in the chat thread and follow up with more specific questions.
- Check the roadmap or open an issue on GitHub if you want features that are not available yet.

Key features
Chat With Any Public Repository
The core feature turns a public GitHub repository into a chat you can question. Ask about the project's purpose, its structure, or a specific behavior, and the tool replies in natural language. You get an answer in seconds instead of scrolling through source files to piece one together.
Natural Language Questions
You do not need to know the repository's internal names to ask. Questions in everyday wording are enough to reach an answer, which lowers the barrier for newcomers and for anyone skimming a project they do not own.
URL Prefix Shortcut
Any GitHub repository URL works with a talkto prefix, so you can jump straight from a repo page to a conversation about it. That shortcut removes the setup step of copying a link into a separate form.
Repository and Query Caching
The project caches repositories and past queries, which speeds up repeated work on the same codebase. Revisiting a repository you already asked about comes back faster than a cold start.
Open Source and Self-Hostable
TalkToGitHub is released under the MIT license, and the repository ships with setup instructions for running it yourself. You can read the code, report issues, or contribute on GitHub, and teams that prefer to keep things in-house can run their own copy.
Built on a Modern Web Stack
The project pairs a React and Vite front end with a Python and FastAPI backend, and the hosted tool uses a large language model to read repositories and answer questions. The stack is a common one, which makes the project easier to follow if you want to learn from it or extend it.
Pros and cons
Pros
- Fast way to get the gist of a public repository without cloning it or reading files one by one.
- Plain language questions are enough, so you do not need the project's internal vocabulary to start.
- The `talkto` URL prefix makes starting a conversation about a repo a one step action.
- Open source under the MIT license, so you can inspect the code, self-host it, or contribute.
Cons
- Only public repositories are supported, so private or company code is out of scope.
- Large repositories and per file or per folder questions are still on the roadmap rather than available.
- Answer quality depends on the project's own documentation and structure, so thin repos give weaker answers.
- The hosted service has no stated pricing or usage limits, which makes heavy use hard to plan.
Frequently asked questions
It lets you chat with a public GitHub repository in plain language. You ask questions about what the project does or how a feature works, and it answers in a chat thread instead of making you read the code file by file.
