An AI Tool for GitHub That Generates Documentation: The Complete Guide

Ask any developer what they like least about software engineering, and you’ll often get the same answer: writing documentation. It’s tedious, repetitive, and always out of date. Yet, without good documentation, projects slow down, new developers struggle to onboard, and customers get frustrated.

Now imagine if GitHub itself could generate documentation every time you pushed code. Imagine if your commits didn’t just live in version history but automatically became clear documentation, release notes, or even SEO articles for your product. That’s no longer wishful thinking—it’s exactly what AI is enabling today.

In this article, we’ll explore the problem with documentation, why GitHub is the perfect place to solve it, and how DeployIt—an AI tool for GitHub that generates documentation—transforms the way teams communicate.

1. Why Documentation Is Broken

1.1 Developers Hate Writing It

Most developers don’t wake up excited about writing documentation. They prefer solving problems, shipping code, and building new features. Writing user-friendly explanations feels like a distraction from “real” work.

1.2 Documentation Gets Outdated Fast

Even if teams start with good documentation, it quickly falls behind. New features ship, bugs get fixed, APIs change—and the docs don’t keep up. Outdated docs are sometimes worse than no docs at all, because they mislead users and teammates.

1.3 The Hidden Costs of Poor Docs

  • Slower onboarding: new hires take longer to become productive.
  • More support tickets: users keep asking the same questions.
  • Misalignment: product, marketing, and support teams don’t know what changed.
  • Wasted developer time: devs get pulled back to explain features instead of building them.

Documentation is necessary, but the way we handle it today is broken.

2. Why GitHub Is the Perfect Source of Truth

2.1 Everything Starts with GitHub

For modern software teams, GitHub is the heart of development. Every commit, pull request, and branch is a record of what’s happening in the codebase.

2.2 Commits Already Contain Knowledge

Commit messages describe changes. Diffs show what files were modified. Pull requests provide context, discussions, and decisions. Together, they hold all the raw data needed to create documentation.

2.3 No Extra Workflow Needed

Developers don’t need to log into another tool or duplicate information. If documentation can be generated directly from GitHub, it stays aligned automatically.

That’s why GitHub is the ideal place to solve the documentation problem—and why an AI tool that integrates there can have massive impact.

3. How AI Changes Documentation Forever

Artificial intelligence, and especially large language models (LLMs), are revolutionizing content creation. But their real power isn’t just writing generic text—it’s transforming structured inputs into human-friendly outputs.

3.1 Commits as Input, Docs as Output

With the right AI, conventional commits, PR titles, and diffs can be turned into:

  • Release notes
  • Technical documentation
  • Developer onboarding guides
  • Customer-facing knowledge base articles
  • SEO-optimized blog posts

3.2 Always Up to Date

Because the AI pulls directly from code commits, documentation evolves automatically with the product. No more “last updated two years ago.”

3.3 Contextual Accuracy

Unlike generic AI writers, an AI tied to your GitHub repo has access to the real source of truth. This ensures outputs are consistent with your actual code.

4. Meet DeployIt: The AI Tool for GitHub That Generates Documentation

DeployIt is a GitHub App designed to solve the documentation problem once and for all.

Its promise is simple: “From commits to content, instantly.”

DeployIt connects to your repositories, indexes your codebase, and turns everyday development activity into ready-to-use documentation, release notes, and more.

But its real breakthrough feature is something even more powerful: Chat With Code.
