How to Automate Your GitHub Workflow with ChatGPT

This integration connects ChatGPT with GitHub to help automate tasks like reviewing pull requests, writing documentation, summarising issues, and even generating code suggestions - right inside your development workflow.

🔹 Setup & Access

To connect ChatGPT with GitHub, you’ll need to choose how you want to integrate: either via OpenAI's API, third-party tools, or custom plugins/scripts.

Here’s how to do it step-by-step using the API + GitHub setup (recommended for most devs):

Using OpenAI’s API + GitHub:

• Sign up for an OpenAI API key

• Use GitHub Actions or a GitHub App to create workflows that call ChatGPT via the API

• Example: Trigger a summary generation every time a new issue or PR is opened

• Use tools like LangChain, LlamaIndex, or gpt-engineer to customise workflows

• Store your API key in GitHub Secrets for secure access

Popular Community Tools You Can Try:

• gpt-pr-review: Generates pull request reviews with GPT

• ChatGPT-Assistant for GitHub Issues: Summarises and classifies GitHub issues

• Readme-AI: Uses GPT to generate READMEs from your repo files

🔹 Cost

To use ChatGPT with GitHub:

• OpenAI API Pricing (GPT-4-turbo):

• Input: ~$10–$15 per million tokens

• Output: ~$30 per million tokens

• Platform Requirement: No ChatGPT Plus needed - this works with an API key

• Third-party tools: Some may have their own pricing tiers or be free on GitHub

🔹 Competitors

Here are a few tools and platforms offering GitHub integrations or similar AI code review support:

🔹 Let’s Compare

Why compare? Because not all tools do the same thing. Some are focused on inline coding, others on reviewing, documentation, or workflows.

🔹 Why ChatGPT Stands Out

Unlike Copilot or other assistants that are pre-set, ChatGPT offers total flexibility. 

You define the prompts, the use cases, and the automation flow. That means it can be more useful for documentation, summarising issues, PR reviews, or even generating custom markdown reports - not just writing code.

This open-ended model gives developers more power to shape their workflows.

🔹 Real-World Use Cases

These are suggestions based on common dev tasks - and how ChatGPT can help:

1. Summarise long GitHub issues

2. Generate PR descriptions

3. Write initial README files from code structure

4. Comment on code diffs

5. Label issues based on content

6. Create weekly update summaries

7. Auto-generate changelogs

8. Write test documentation

9. Suggest fixes based on reported issues

10. Act as a custom bot responding to repo questions

🔹 How Much Time ChatGPT Saves You for Coffee ☕

Estimated weekly savings: 8–9 hours, aka a full day of dev time

🔹 Frozen Light Summary

You now know how ChatGPT integrates with GitHub, what tools to use, what it costs, and how it stacks up against others like Copilot and Gemini.

More than just an IDE assistant, ChatGPT can help you handle the text-heavy parts of development: issues, summaries, docs, updates, and more - your workflow, your way.
