Writing Better Technical Docs with AI.
Use AI as a writing partner to produce clear, consistent documentation your team will actually read.
Good documentation saves thousands of hours. Bad documentation wastes them. AI won’t write your docs for you, but it’s an excellent writing partner.
Where AI helps most
AI is great at the parts of documentation that slow engineers down:
- First drafts — getting something on the page is the hardest part
- Consistency — matching the tone and format of existing docs
- Examples — generating code samples and usage patterns
- Translation — converting dense technical details into clear language
A practical workflow
Step 1: Dump your knowledge
Don’t try to write polished docs from scratch. Instead, brain-dump everything you know about the feature or system into your AI tool:
Here’s how our authentication system works: [paste notes, code snippets, Slack messages, whatever you have]
Turn this into a technical document with these sections: Overview, How it works, Setup guide, API reference, Troubleshooting.
Step 2: Review the structure
AI is good at organizing information logically. Check:
- Does the document flow from high-level to detailed?
- Are there gaps where you need to add more detail?
- Is the target audience right? (New dev vs. experienced contributor)
Step 3: Fix the voice
AI tends to be verbose and formal. Run a second pass:
Rewrite this to be more concise. Use active voice. Remove any sentences that don’t add information. Our docs style is direct and practical — no fluff.
Step 4: Generate examples
This is where AI really shines:
Generate 3 code examples showing how to use this authentication API:
- Basic login flow
- Token refresh
- Error handling
Step 5: Human review
AI-generated docs need a human to verify:
- Technical accuracy — AI can hallucinate API parameters or behaviors
- Completeness — did it miss edge cases you know about?
- Relevance — is everything in the doc actually useful?
What not to do
- Don’t publish without review. AI makes confident-sounding mistakes.
- Don’t use AI for architecture decisions. Document what you decided, not what AI suggests.
- Don’t let AI add unnecessary sections. If your doc doesn’t need a “Prerequisites” section, don’t include one just because the template has it.
The result
Teams using AI-assisted documentation typically produce docs 3x faster with comparable quality. More importantly, they actually write docs instead of putting it off because “it takes too long.”
The best documentation is the documentation that exists. AI helps you get it written.
