Hook’s nimble context-sensitive navigator is loved by people who need to focus on their project information, such as professors, researchers, writers, lawyers, software developers, students, managers, & creatives. Stay in flow, with Hook!

As Brett Terpstra on Mac Power Users said over the summer: “Hook is a direct way to say: this file hooks to this file, and this file hooks to this OmniFocus task”

And David Sparks on Mac Power Users “It’s really kinda ingenious.”
