Criticly ✓

Criticly is a privacy-first AI companion for critical thinking, designed to help you analyze, question, and refine ideas instantly. Available as a lightweight Mac and Windows app, Criticly lets you select text from emails, research papers, Slack messages, or web pages and receive structured insights, critiques, and clarifying questions in seconds.

Its floating bar keeps these capabilities directly within your workflow. Criticly includes 7 built-in AI tools—6 critical thinking tools plus Quiz—to help you distill complex information, evaluate reasoning, identify bias, explore opposing viewpoints, and test your understanding. Custom Commands also let you create personalized tools for your own tasks and thinking workflows.

Unlike most AI productivity tools, Criticly is built with privacy at its core. It never stores your selected text, uses local execution where possible, and supports custom AI model integrations such as GPT, Claude, and Gemini. Whether you’re writing, studying, researching, or analyzing, Criticly turns passive reading into active reasoning—making your thinking sharper, faster, and more structured without interrupting your workflow.
