How Erratly works

Erratly is a tiny menu bar app — no dashboard, just a compact Settings window. Here's what to expect from first launch to everyday use, including the one-time model download.

1. 01
   Download & launch

   Move Erratly.app to your Applications folder and open it. A small ✦ icon appears in your menu bar — that's the whole app.

   
2. 02
   First launch downloads the model

   Erratly needs a small language model to run corrections. On first launch, it downloads it automatically from Hugging Face (~1.8 GB). The menu bar icon shows ⏳ while this happens — it can take a few minutes depending on your connection.

   
3. 03
   Grant Accessibility permission

   macOS will ask for Accessibility access. This is what lets Erratly read the text you select and replace it in place, in any app. Grant it in System Settings when prompted.

   
4. 04
   Ready to use

   Once the icon shows ✦, Erratly is ready. The model is cached on your Mac, so this download only happens once — no internet connection needed after that.

   
5. 05
   Fix text anywhere

   Select any misspelled text, double-tap Control (or your own shortcut), and Erratly corrects it in place. The icon briefly shows ⟳ while it's working, then goes back to ✦.

   
6. 06
   Local by default, remote if you want

   Corrections run entirely on your Mac using the downloaded model — your text is never sent anywhere. If you'd rather use a cloud model, open Settings… from the menu bar, choose Remote API and enter an OpenAI-compatible base URL, model name and API key (stored in the Keychain).
7. 07
   Make it yours

   In Settings you can also record a different shortcut and pick a small, medium or large review panel.
