The Developer's Guide to Dictating Docs Without Losing Your Mind

Most developers do not hate writing documentation because they lack the knowledge. They hate it because it is slow. After hours of focused coding, opening a blank doc and typing out explanations in plain English feels like running a second marathon after the first one. The friction is the problem, not the content.

Dictation does not make documentation enjoyable. But it cuts the time enough that you might actually do it.

Where Dictation Fits in a Dev Workflow

Not everything you write as a developer is code. There are READMEs, inline comments, PR descriptions, Slack messages, Notion pages, onboarding guides, and postmortems. Most of these are pure prose, and prose moves faster when you speak it.

The distinction matters because developers sometimes assume voice input is irrelevant to their work. If you spend most of your day at a terminal, that assumption is understandable. But if you spend even 30 minutes a day writing explanatory text, dictation can save you real time.

Dictating Comments and Inline Documentation

Inline comments are a good starting point. They are short, low-stakes, and easy to dictate without breaking your flow. Place your cursor at the comment line, press the dictation key, say what the function does, stop. With a tool like VoiceInk running locally on your Mac, the text appears immediately without any context switch or app change.

For longer explanations, like a block comment above a complex function, try speaking the explanation as if you are describing it to a colleague who just joined the team. That framing tends to produce clearer writing than trying to compose formally from the start.

Writing READMEs by Talking Through Them

A README has a predictable structure: what this does, why it exists, how to install it, how to use it, what the gotchas are. That structure makes it easy to dictate section by section.

Open the file, put your cursor under the first heading, and just explain the project out loud. You built the thing. You know it. The explanation is already in your head. Typing it forces you to translate thought into keystrokes one at a time. Speaking it lets you just say it.

Expect the first pass to be rougher than your typed drafts. That is fine. A rough README that exists is worth more than a polished one that does not.

PR Descriptions and Async Communication

PR descriptions are where many developers write the bare minimum: "fixes bug," "updates config," "WIP." Partly this is culture, but partly it is friction. Writing a useful description that explains context, approach, and tradeoffs takes time when typed.

Dictated, a thorough PR description takes about 90 seconds. You already know what you changed and why. Say it. Your reviewer will thank you, and future-you reading the git history six months from now will thank you more.

The same logic applies to Slack messages that require actual explanation, incident summaries, and any async communication where brevity has been sacrificed not by choice but by the cost of typing.

What to Watch Out For

Code itself is not a good dictation target. Variable names, syntax, punctuation: these are all easier with a keyboard. Do not try to dictate function signatures or JSON. That is not what this is for.

Also, technical terms can trip up any transcription system. If your codebase uses unusual names or domain-specific jargon, you may need to spell some things out or fix them in a quick pass. Build that correction step into your habit and it becomes invisible.

The Broader Point

Documentation debt is a real cost. It slows onboarding, causes duplicate questions, and makes codebases harder to maintain. The reason it accumulates is usually not ignorance but friction. Anything that lowers the cost of writing explanation is worth trying.

Spend a week dictating your docs and comments. See if the output improves. The bar for success is not perfect prose. It is prose that exists.
