About
Curio is a Mac notebook app for gathering notes, research, and documents in freeform idea spaces. Each project is a single local file on your Mac, so your work stays private, works offline, and isn't uploaded to remote servers. You can combine text notes, Markdown, images, PDFs, documents, web links, and multimedia in one place, and organize them with integrated mind maps, lists, tables, index cards, albums, pinboards, and Kanban boards.
Curio also includes metadata such as tags, dates, priority, ratings, and custom cross-references to help you find, track, and manage material within a project. Its features are used by people in many fields, including designers, writers, students, scientists, project managers, programmers, lawyers, and entrepreneurs. Curio offers a 2-week free trial, and its Standard and Pro editions differ in the features they include.
