Fix Spanish Grammar Instantly on Your Mac with WunderType

You already write in Spanish. Maybe you grew up speaking it at home, maybe you studied it for years, or maybe you live in a bilingual city where switching between English and Spanish is just Tuesday. Either way, you know the frustration: you type a paragraph in Spanish and something feels off. A missing accent here, a word that is technically correct but sounds unnatural there. You need a tool that can fix Spanish grammar without rewriting your voice.

WunderType is a macOS menu bar app that corrects and improves text in any application. With its Spanish Corrector Pro custom prompt, you select your Spanish text wherever you typed it, press ⌥⇧⌘S, and get grammatically correct Spanish back in place -- accents fixed, word choices refined, syntax polished. No browser tab. No copy-paste. No interruption to your workflow.

How to Fix Spanish Grammar System-Wide on macOS

Most Spanish grammar checkers live inside a browser or a dedicated app. That works until you need to write an email in Mail, draft a message in Slack, or compose a document in Pages. Then you are back to copying text into a web tool, waiting for corrections, and pasting it back. WunderType eliminates that friction entirely.

The Spanish Corrector Pro prompt works in every macOS application. Here is what it does in practice:

Before

Necesito enviar este email a mi cliente, pero estoy teniendo problemas con la gramatica. 'Tengo que hablar con ellos' suena un poco informal.

After

Necesito enviar este correo electrónico a mi cliente, pero estoy teniendo problemas con la gramática. 'Tengo que hablar con ellos' suena un poco informal.

Two corrections that make a real difference. First, email becomes correo electrónico -- the proper Spanish term instead of an anglicism. Second, gramatica gains its accent to become gramática, fixing an orthographic error that any native reader would notice. The rest of the text stays exactly as you wrote it because it was already correct. That is the point: Spanish Corrector Pro fixes what needs fixing and leaves your voice intact.

Why This Is Not a Translation Tool

If you want to translate English into Spanish, WunderType can do that too -- you can create a translation prompt for that purpose. But Spanish Corrector Pro solves a different problem entirely. It is built for people who already write in Spanish and want their existing Spanish text corrected.

The distinction matters. A translation tool takes English input and produces Spanish output. A Spanish grammar corrector takes Spanish input and produces better Spanish output. The corrections are subtle -- accents, anglicisms, gender agreement, preposition choices -- because the writer already knows Spanish. They just need a safety net for the details that slip through when you are typing quickly or thinking in two languages at once.

Who Benefits from a Spanish Grammar Corrector

This prompt is designed for specific groups of writers who deal with Spanish text daily:

• Heritage speakers -- who grew up speaking Spanish but may not have had formal written instruction and sometimes miss accents or use anglicisms absorbed from English-dominant environments
• Spanish learners -- at intermediate or advanced levels who can compose in Spanish but need help catching grammatical errors they have not fully internalized yet
• Bilingual professionals -- who write client emails, documents, and messages in Spanish alongside English and want both languages polished to the same standard
• Content creators -- who publish in Spanish and need a fast way to catch errors before posting on social media, blogs, or newsletters

Set Up Spanish Corrector Pro in WunderType

1. Click the WunderType icon in your Mac's menu bar and open Custom Prompts
2. Create a new prompt named "Spanish Corrector Pro" with an instruction like: You are a Spanish language expert. Correct any grammar, spelling, accent, and word choice errors in the selected Spanish text. Replace anglicisms with proper Spanish equivalents. Fix accent marks, gender agreement, and preposition usage. Preserve the writer's original tone and meaning. Output only the corrected text.
3. Assign ⌥⇧⌘S as the keyboard shortcut

From that point on, the shortcut works in every app on your Mac. Select Spanish text in Mail, Notes, Pages, Slack, your browser -- anywhere -- and press the shortcut to get corrected text back instantly.

Beyond Grammar: Build a Complete Spanish Writing Toolkit

Spanish Corrector Pro handles grammar, but WunderType's Custom Prompts let you build an entire suite of Spanish-language writing tools:

• Spanish Corrector Pro -- fixes grammar, accents, and anglicisms in existing Spanish text
• Formal Spanish -- elevates casual Spanish to a professional register for business correspondence
• Spanish Simplifier -- rewrites complex Spanish sentences into clearer, more direct language
• Translate to Spanish -- converts English text into natural Spanish (a separate use case from correction)

Each prompt gets its own keyboard shortcut. You build a personal Spanish writing toolkit that works across every application on your Mac.

Private, Fast, and Built for macOS

WunderType connects to OpenAI or runs entirely offline through local Ollama models. With a local model, your Spanish text never leaves your Mac -- no cloud processing, no third-party servers reading your emails or documents before you send them. For professionals handling sensitive correspondence in Spanish, that privacy matters.

And because WunderType lives in your menu bar, it adds zero friction to your writing process. There is no app to switch to, no browser tab to find, no text to copy and paste. Select, press the shortcut, done.
