"Summarize my notes about X" ā just ask, and AI searches your notes to find the answer. Watch the search happen in real time, so you always see what it's basing the answer on.

AI can even suggest creating a new note from your conversation. Every past question and answer is saved for you to revisit anytime. [AI-Powered Structuring] Type or speak your rough notes ā IdeaHatch's AI reads between the lines and asks smart clarifying questions ("What tone are you going for?", "Who's the audience?"), then transforms your raw input into a well-structured Markdown document that sounds like you.
