Technical Style Guide: Your AI Technical Writing Editor on macOS

Technical documentation should be clear, not clever. Yet most technical writers spend hours untangling jargon-heavy sentences that obscure meaning rather than convey it. WunderType acts as your technical writing editor on macOS, transforming dense prose into clean, readable documentation with a single keyboard shortcut.

Why Technical Writers Need a Dedicated Editor

Style guides like the Google Developer Documentation Style Guide and Microsoft Writing Style Guide share a common principle: use simple, direct language. But applying those rules consistently across hundreds of pages is exhausting. That is exactly the kind of repetitive, rule-based task that AI handles well.

WunderType sits in your macOS menu bar and works inside any application — your code editor, wiki, CMS, or email client. Select overwritten text, press ⌥⇧⌘E, and get back a cleaner version instantly. No browser extensions, no copy-pasting into a separate tool, no context switching.

Setting Up a Technical Writing Editor Prompt

WunderType's power lies in Custom Prompts — user-defined AI text actions with their own instructions and keyboard shortcuts. Here is how to create a Technical Style Guide prompt:

1. Open WunderType from the menu bar
2. Navigate to Custom Prompts and click Add
3. Set the name to Technical Style Guide
4. Assign the shortcut ⌥⇧⌘E
5. Enter your instruction — for example: "Rewrite the text following technical writing best practices. Replace jargon with plain language. Use active voice. Keep sentences short and direct. Remove filler words. Add practical guidance where the original is vague."

Before and After: Jargon to Clarity

Here is a real-world example of the Technical Style Guide prompt in action.

Before

The system's API utilizes a proprietary protocol for data transmission. This protocol, while robust, can occasionally exhibit latency during high load periods.

After

The system's API uses a custom protocol for data transmission, which may experience latency during high loads. Network timeouts should be handled gracefully.

Notice the changes: "utilizes" becomes "uses," "proprietary" becomes "custom," and a vague description of latency is replaced with actionable guidance about handling timeouts. Every edit follows established technical writing conventions — prefer short words, cut unnecessary qualifiers, and give the reader something they can act on.

Who Benefits Most

This prompt is especially useful for:

• Technical writers maintaining API docs, user guides, and knowledge bases
• Documentation teams enforcing a consistent style across contributors
• Developer advocates turning internal engineering notes into public-facing content
• Engineers writing READMEs, pull request descriptions, and runbooks

Why WunderType Over Other Tools

Most grammar checkers flag obvious typos but ignore the subtler problems in technical writing — passive voice burying the actor, nominalizations hiding the action, and jargon alienating the reader. A custom prompt with explicit style rules catches all of these because you control the instruction.

WunderType also keeps your text private. Run a local model through Ollama and your documentation never leaves your machine — critical for teams working on proprietary APIs or pre-release features.
