A small app that does exactly one thing, seriously well.
In-place replacement
Reads and rewrites the selection directly. Falls back to copy/paste for Electron. Your clipboard is always restored.
Custom prompts
Unlimited AI instructions of your own. Translate, summarise, rewrite for audience. A 'Generate' button turns plain English into an optimised system prompt.
Shortcut per prompt
Bind any prompt to any key combo. Muscle memory for your personal writing stack.
On-device AI
New in 1.5: run AI models directly on your Mac's GPU via Apple MLX. No Ollama, no API key, no internet after a one-time download. Apple Silicon only.
Menu-bar only
No Dock icon, no background daemon. One status dot tells you the provider is reachable.
Sandboxed & lean
~20 MB sandboxed app. Network-client entitlement only. No files, no camera, no microphone.

From people who type all day.
“I had been looking for a way to check my punctuation with local AI only. I was stoked to find WunderType was there ready for me to find. It fits the bill perfectly. Now I simply use my hotkey to get the job done with WunderType. It works great on Intel and Apple Silicon. I highly recommend WunderType.”
“I used Grammarly before, but it has no way to work offline with a local AI. This app offers exactly what I was looking for. It's easy to use and does precisely what it's supposed to. I'm very satisfied.”
“Works very well. Definitely recommend it!”

Questions, answered.
Does it really work in any app?–
Anywhere the macOS Accessibility API can read a text selection — which covers virtually every native and browser app. For Electron apps that don't expose text nodes, WunderType falls back to simulated copy/paste and restores your clipboard afterward.
What is On-Device AI? Do I still need Ollama?+
New in 1.5, On-Device AI runs models directly on your Mac's GPU using Apple's MLX framework — no Ollama, no API key, no internet after a one-time model download. Pick from four models (Gemma 3 1B, Granite 2B, Phi-4 Mini, or Gemma 3 4B), and your text is processed entirely inside the app. It's the recommended default for new users. Requires Apple Silicon (M1 or later); on Intel Macs, Ollama remains the local option.
Is Ollama really free?+
Yes. Ollama is free, open-source, and runs entirely on your Mac. WunderType talks to it at localhost:11434. No usage caps, no API key, no account.
What about OpenAI / OpenRouter costs?+
You bring your own API key; WunderType has no intermediary server. You're billed directly by OpenAI or OpenRouter for whichever model you pick.
Can I use multiple providers?+
Yes. Set a default, then override per prompt. Some users run grammar on the built-in On-Device AI and reserve OpenAI for heavier rewrites.
Where is my API key stored?+
Inside the macOS Keychain — encrypted at rest, never in UserDefaults, never in a plain file, never synced by us.
Will it slow my Mac down?+
No. WunderType is a sandboxed menu-bar agent (~20 MB) with no background daemons. It only wakes when you press a shortcut. On-Device AI runs inference on the GPU just for the moment it corrects your text, then idles.
