Dictating Code Comments and Docs: A Developer's Guide

Developers are not just writing code. On any given day you're writing commit messages, pull request descriptions, inline comments, README files, Slack explanations, and technical specs. That's a lot of prose, and most of it is typed slowly with the same hands you need for everything else.

Voice dictation doesn't replace coding. It handles the writing around the code.

What's Actually Worth Dictating

Not all developer output is a good fit for dictation. Syntax is precise, abbreviated, and full of symbols that voice tools handle poorly. Dictating a function is slower and more error-prone than typing it.

But a lot of what developers write is plain English:

• Inline comments explaining why something works the way it does
• README sections describing setup and usage
• PR descriptions summarizing what changed and why
• Ticket comments and status updates
• Confluence or Notion documentation
• Slack messages to teammates

All of this comes out faster and more naturally when spoken. A PR description that takes five minutes to type takes 90 seconds to dictate.

The Comment Problem

Inline comments are chronically under-written. Part of the reason is friction. After spending 20 minutes working out a tricky piece of logic, nobody wants to spend another 3 minutes typing a careful explanation. So the comment says "handle edge case" and the next developer is left guessing.

Dictating comments removes most of that friction. You figured out the logic, now just say what you did and why. Click above the function, press your dictation shortcut, and talk for 15 seconds. You'll write better comments, more often, with less effort.

VoiceInk drops text exactly where your cursor is, so there's no app switching. You stay in your editor.

Writing Documentation You'll Actually Finish

Documentation is the task most developers delay until it's urgent. Part of that is the gap between thinking something and writing it down carefully. You understand the system; writing it out feels laborious.

Try dictating a first pass. Open a blank document and just explain the system out loud, as if you're onboarding a new teammate. Don't worry about structure. Say what it does, how to run it, what breaks, what you'd change. Talk for 10 minutes.

You'll have a rough draft of real, useful documentation. Then you format and edit. The hard part, actually explaining the thing, is done.

Commit Messages and PR Descriptions

Commit messages are usually too short because typing a longer message feels like overhead. Dictating a two-sentence commit message takes about 8 seconds. You have no excuse to write "fix stuff" anymore.

PR descriptions benefit even more. A good PR description saves your reviewer significant time and makes your changes easier to merge. Dictate it the way you'd explain the PR to a colleague standing next to you: what the problem was, what you changed, and anything that needs attention.

Hands-Off Note Capture

One underused developer habit: dictating notes while reviewing code or reading documentation. Instead of alt-tabbing to a notes app and typing, you speak a quick note and it lands wherever you want it. "This API is deprecated, we need to flag this in the next sprint" takes three seconds to say.

Over a long session, this keeps your hands closer to the keyboard for actual coding while still capturing the thinking happening in parallel.

Getting Started

Start with one PR description this week. Describe the change out loud before you type it. Notice whether what you said was clearer than what you usually write.

If it is, that's your cue. Developers spend more time on words than they admit. Saying some of those words out loud might be the smallest change with the largest return.
