Dictating Documentation: A Developer's Honest Take

Nobody writes documentation because they enjoy it. You write it because future-you or a teammate will be lost without it. The problem is the cost. After a long coding session, opening a blank doc and typing out what you just built feels like running a second marathon.

I started using voice dictation for docs about eight months ago. Here's what actually works.

The Right Moments to Dictate

Voice documentation works best immediately after you finish something. Your mental model is fresh. You remember the edge cases, the decisions you considered and rejected, the gotchas that took two hours to find.

If you wait until end of sprint, you'll be reconstructing from memory and git commits. That's slower and the output is worse.

The workflow I use: when I close a PR or finish a function I want to document, I switch to my notes app, press the VoiceInk shortcut, and just explain what I built as if I'm talking to a new teammate. No structure, no formatting, just the information dump. It takes three to five minutes.

That raw transcript becomes the first draft. Cleanup takes another five minutes. Total time: under ten minutes for documentation that would have taken me thirty to write from scratch.

What to Dictate and What to Type

Voice works well for prose documentation: READMEs, architecture decision records, onboarding guides, API explanations, and inline comments for complex logic.

It works less well for code itself. Dictating syntax is slow and error-prone. Saying "open paren, single quote, slash API slash users slash, single quote, close paren" is nobody's idea of a good time. Keep your hands on the keyboard for code.

The split is roughly: type the code, speak the explanation. That combination is faster than typing both.

Inline Comments by Voice

This one surprised me. Long inline comments explaining why a function exists or why an obvious approach was avoided are exactly the kind of writing that benefits from dictation.

I'll write the code, then park my cursor above the relevant block, press my dictation key, and say what I'd say to someone reviewing the PR. Two or three sentences. Done.

The alternative is typing it, which means I'm in writing mode while still in a coding context. Switching costs add up. Speaking the comment and staying mentally in the codebase is cleaner.

The Noise Problem

Open offices and coffee shops are real obstacles. If you work somewhere loud, a directional microphone or a headset makes a significant difference. The built-in MacBook mic handles quiet environments well, but it struggles with background noise.

VoiceInk runs locally, which means there's no audio going to a server. That matters in some workplaces where sending voice data to third-party APIs isn't allowed. Worth checking if you work in a regulated environment.

Capture Before You Forget

The highest-value use case isn't formal documentation. It's capture. You're debugging at 11 PM, you figure out why a race condition is happening, and you need to write it down before you lose the thread.

Opening a doc and typing is enough friction to skip it. Pressing a key and speaking two sentences is not. That friction difference is where knowledge gets lost or preserved.

I keep a running voice-dictated log of decisions, weird bugs, and things I'll need to explain later. It takes almost no time in the moment and pays back considerably when I'm onboarding someone or writing a postmortem.

One Shift in Mindset

The developers I know who resist dictation usually imagine themselves reciting formal documentation into a microphone. That's not how it works well.

Speak the way you'd explain it in Slack. Casual, direct, complete. Clean up the transcript for five minutes if it's going somewhere public. That's the workflow.

If you've been putting off the docs on your last feature, try talking through them right now. It's probably faster than you think.
