How to Connect GitHub to ChatGPT (Step-by-Step)
If your engineering team uses GitHub, you can now connect it to ChatGPT and query your repos in plain English. No more writing GraphQL queries or clicking through dozens of PRs — just ask ChatGPT what you need to know.
This guide walks you through the full setup: connecting GitHub, querying issues and PRs, building a Custom GPT for engineering workflows, and managing access. We also cover considerations for Canadian businesses whose repos may contain customer-related data.
What You Need Before Starting
- ChatGPT Plus, Team, or Enterprise — the free tier does not support connected apps
- A GitHub account with repos you want to query
- GitHub org admin approval (if your organization restricts third-party app access)
Step 1: Open ChatGPT Settings
Log into chat.openai.com. Click your profile icon in the bottom-left corner, then select Settings. Navigate to Connected Apps (or Data Sources, depending on your plan). You should see GitHub listed alongside Google Drive and other connectors.
Step 2: Authorize GitHub Access
Click Connect next to GitHub. You will be redirected to GitHub to sign in and approve permissions. You can choose which repositories and organizations to authorize. ChatGPT requests read access — it does not push code, merge PRs, or modify anything in your repos.
Once you approve, you will be redirected back to ChatGPT with a confirmation that GitHub is connected.
Tip for IT admins:
If your GitHub organization restricts third-party app access, an org admin will need to approve the ChatGPT integration in Organization Settings → Third-party access → OAuth App Policy. You can restrict which repos the integration can access at the organization level.
Step 3: Wait for the Initial Sync
After connecting, ChatGPT indexes your GitHub data — issues, pull requests, code files, and activity. This typically takes a few minutes for most repos. You will see a confirmation once the sync is complete. Large organizations with hundreds of repos may take longer.
Step 4: Query Your Repos in Plain English
Open a new chat and start asking questions. ChatGPT will search your GitHub data and reference the relevant issues, PRs, and code. Here are some examples:
- “Summarize all open PRs across the platform repo”
- “Which issues have been open for more than two weeks without activity?”
- “What changes were merged into main this sprint?”
- “Which PRs have been waiting for review for more than 48 hours?”
Real-world use case:
An Engineering Manager overseeing three repos can ask ChatGPT to summarize all open PRs, identify reviews that have been pending for more than 48 hours, and draft a Slack message to the team highlighting blockers — replacing a 45-minute GitHub dashboard review with a 5-minute conversation.
Step 5: Build a Custom GPT with GitHub Knowledge
For repeatable workflows, create a Custom GPT that uses your GitHub repos as its knowledge base. This turns ChatGPT into a dedicated assistant that follows your team's specific engineering process every time.
- Go to Explore GPTs in the ChatGPT sidebar
- Click Create in the top right
- Name your GPT (e.g., “Sprint Review Assistant”)
- Write instructions that define your sprint process, PR review criteria, and status report format
- Under Knowledge, connect your GitHub repositories
- Test with real questions, then publish to your engineering team
A Custom GPT is especially useful when multiple team leads need the same workflow — sprint summaries, PR review tracking, or preparing release notes in a consistent format.
Step 6: Manage or Disconnect Access
To revoke access, go to Settings → Connected Apps and click Manage next to GitHub. You can disconnect entirely or adjust which repos ChatGPT can access. Disconnecting removes ChatGPT's ability to read your repository data immediately.
Frequently Asked Questions
On ChatGPT Team and Enterprise plans, OpenAI does not use your data for model training. Your repository data remains private to your workspace. For maximum security, use the Enterprise plan which includes SOC 2 compliance, SSO, and admin controls. If your repos contain customer data or credentials (they shouldn't), review OpenAI's data processing terms before connecting.
Yes, if you authorize access during the OAuth flow. You can choose which repositories — public and private — ChatGPT can access. You can also restrict access to specific organizations or repos during setup.
No. The ChatGPT GitHub connector provides read-only access. ChatGPT can search issues, summarize PRs, and analyze code activity, but it cannot push commits, merge pull requests, close issues, or modify anything in your repositories.
Yes. The GitHub connector is available on ChatGPT Plus ($20 USD/month), Team ($25 USD/user/month), and Enterprise plans. The free tier does not support connected apps. For engineering teams, Team or Enterprise is recommended for shared workspace access.
ChatGPT queries indexed data, not the GitHub API directly in real-time. This means typical GitHub API rate limits do not apply to your queries. However, very large repositories or organizations with thousands of issues may take longer to index initially.
Yes. On ChatGPT Team and Enterprise plans, you can share Custom GPTs that reference GitHub repos with your entire organization. This is ideal for engineering managers who want consistent PR summaries and sprint tracking without each developer configuring their own connection.
