Every developer writes documentation — READMEs, API docs, blog posts, internal wikis, runbooks. But most of us treat writing tools as an afterthought, banging out docs in whatever text editor happens to be open.
I spent the last year experimenting with different Mac apps specifically for technical writing, and these seven genuinely improved both the quality and speed of my documentation workflow.
1. Obsidian — Your Second Brain for Technical Notes
Obsidian is a local-first markdown knowledge base that links your notes together like a personal wiki. The bidirectional linking means your API notes, architecture decisions, and meeting notes all reference each other naturally. The graph view alone has saved me from writing duplicate docs more times than I can count.

2. CleanShot X — Screenshots That Actually Explain Things
CleanShot X makes annotated screenshots trivial. You can blur sensitive data, add numbered steps, record quick GIFs, and pin screenshots on your desktop while you write. If your documentation has any visual component — and it should — this app pays for itself in a single week.

3. Wispr Flow — Dictate Your First Drafts
Wispr Flow is a voice-to-text tool that actually understands technical jargon. I use it to dictate rough first drafts of documentation before cleaning them up in markdown. It's shockingly good at handling terms like "Kubernetes," "GraphQL," and function names without mangling them.

4. TokenBar — Know What Your AI Writing Assistant Costs
TokenBar sits in your menu bar and tracks token usage across every LLM API call in real time. If you use ChatGPT, Claude, or any AI to help draft or edit documentation (and let's be honest, most of us do now), TokenBar tells you exactly what each session costs. It's a $5 lifetime purchase and weighs almost nothing.

5. Marked 2 — Live Preview That Keeps Up
Marked 2 gives you a live-rendered preview of any markdown file as you edit it in your preferred editor. It supports custom CSS, so your preview can match your actual docs site. The word count, readability stats, and broken link detection are genuinely useful for longer technical pieces.

6. Monk Mode — Block the Feeds, Keep the Flow
Monk Mode blocks distracting feeds at the content level — not the entire site. You can still use YouTube for reference videos or Twitter to check a thread, but the infinite scroll is gone. For long writing sessions where one "quick check" of Reddit can destroy 45 minutes, this is the best $15 I've spent.

7. Bear — When You Just Need to Write
Bear is a beautiful, fast markdown editor with just enough organization (tags, not folders) to keep things findable without overcomplicating your workflow. I use it for drafting blog posts and shorter docs before moving them into a repo. The typography alone makes you want to write more.

Honorable Mentions
- Raycast — snippet expansion for boilerplate docs
- Numi — quick calculations inline while writing specs
- Homebrew — install all of the above in minutes
The Takeaway
Documentation doesn't have to feel like a chore. The right tools turn it from "thing I dread" into something that actually flows. If you write technical content on a Mac, try even two or three of these — the compound effect on your writing speed is real.
