Introduction

Documentation is the first thing to become outdated. Developers hate writing it. AI loves writing it. In 2026, "Documentation as Code" has become "Documentation by AI."

The Documentation Crisis

Drift: Code changes, docs don't.
Incompleteness: "I'll document this later" (never happens).
Discovery: Knowledge is buried in Slack threads, not wikis.

Types of AI Documentation

Inline Comments: Explaining complex logic (e.g., Copilot "Explain this").
Function/Class Docs: JSDoc/Docstrings.
API Reference: Swagger/OpenAPI descriptions.
Conceptual Guides: "How to use this SDK" tutorials.
Commit Messages: Automated PR descriptions.

Tools Spotlight: Mintlify & Stenography

Mintlify

Approach: Scans code and generates beautiful documentation websites.
Workflow: VS Code extension highlights code -> "Write Docs" -> Commits to repo.
Feature: "Continuous Documentation" - updates docs when code changes.

Stenography

Approach: Automatic explanation of code blocks.
Focus: Understanding legacy code quickly.

Automating ReadMe & API Refs

Prompt Engineering for Docs: "Generate a README.md for this project. Include: Installation, Usage (with 3 examples), and Configuration."

API Docs: AI can parse a raw router file (e.g., Express.js) and generate a full OpenAPI spec yaml.

Maintaining Freshness

The "Docs CI" Pipeline:

Lint: Check if every exported function has a docstring.
Generate: Run AI doc generator on changed files.
Verify: Human review of generated text.
Publish: Deploy to docs site.

Conclusion

AI transforms documentation from a lagging indicator to a leading indicator of code quality. It enables "Self-Documenting Code" to actually be true.
