Clicknow is a lightweight AI tool for macOS that works on top of any app. Select text and press one button to get a translation, an explanation, a summary, or a content-based search powered by an AI model.
One click instead of copying into ChatGPT
Clicknow fits into your normal workflow so you don’t have to copy text to a browser and back. It can be triggered from any macOS window, supports the PopClip extension, and doesn’t require manual prompt writing or setting up an API key.
Translate, explain, and summarize text
Clicknow helps you quickly understand complex passages and long documents:
- Translate text into different languages
- Explain terms, concepts, and formulas
- Create concise summaries of articles and documents
- Search within selected content using AI
One-time license for macOS
Clicknow runs on macOS 13+ and is sold as a one-time purchase that includes access to the AI model. One license can be used on two devices, which is useful if you work on both a desktop Mac and a laptop.
