A keyboard-driven Mac clipboard manager that OCRs screenshots and runs on-device AI to translate, summarize or rewrite what you copied.

- Automatic Screenshot OCR: Text in screenshots and copied images is read automatically, and a detected table can be converted to Markdown, JSON or HTML.
- On-Device Text Actions: Translate, summarize, rewrite as a business email, turn into a bullet list, or reformat a table using on-device AI on compatible Macs.
- Saved Custom Instructions: Store your own prompts as reusable actions and fire them on the current selection from the keyboard.
- Pick and Paste: Choose an item from history and paste it directly back into the app you were using, either formatted or as plain text.
- Global Keyboard Shortcuts: Dedicated shortcuts open history, pick-and-paste, snippets, screenshot capture, screen OCR and text actions without touching the mouse.
