Ask Questions About Your Codebase With AI Codebase Q&A for GitHub Teams

You can ask questions about your codebase by connecting your repositories to a codebase Q&A tool that indexes all of the code and answers in plain English with citations. In CodeIndex you paste a GitHub URL, the repo is indexed within minutes, and you type questions into a chat box. Each answer links to the files and line ranges it used, so you can verify it before you rely on it.

Pasting files into a general chatbot works for a single function, but it falls apart on real questions because the model only sees what you copied. Questions like "what touches the invoices table?" need the whole codebase in view.

Yes, GitHub Copilot Chat can answer questions about a repository, and GitHub documents using it to explore a codebase. It works best for developers who already hold a Copilot seat and ask from the IDE or from a repository page on github.com. Each person who asks needs a seat, $19 a month on Business or $39 on Enterprise, and answers are scoped to the repository or files in context.

Teams pick a separate codebase Q&A tool when non-developers need answers too, when questions span many repositories, or when they want one flat bill instead of a seat for every person who occasionally asks something. Our GitHub code search alternative page covers where GitHub's built-in tools stop.

It is safe when the tool limits who can see the index and records who asked what. CodeIndex keeps each team's repositories in its own workspace, access is by invitation, and every plan keeps an audit log (7 days on Starter, 30 days on Pro, one year on Enterprise). Enterprise adds SSO and SAML. If policy forbids sending code to any hosted service, a self-hosted tool such as Sourcebot is the better fit, and our Sourcebot alternative page compares the two honestly.

The best questions name a behavior, not a file. "Where do we decide if a trial has expired?", "which jobs run after an order ships?" and "how is the API key checked on incoming requests?" all return a short explanation plus the code that does it. Questions about why something was built a certain way work only as far as the code and comments explain it, because CodeIndex reads code, not Slack history.

Questions that cut across repos are where an index pays off most. If you are also choosing a search tool for the same team, see the source code search engine page and the wider code intelligence platform comparison.

A codebase Q&A tool usually costs $19 to $40 per user per month when priced by seat, which is $380 to $800 a month for 20 people. CodeIndex prices by team instead: Starter is $49 a month for 5 users, 10 repos and 1,000 questions, and Pro is $149 a month for 20 users, 50 repos and 10,000 questions, both billed annually ($99 and $299 month to month). Enterprise at $499 a month annually adds unlimited users and repos, SSO and a one-year audit log.
