Hook for macOS

Link & retrieve key information.

Filing & searching wreck concentration. Using links is fast & easy. With Hook, you can instantly link & access information in your favorite Mac apps! Hook is a CogSci Apps invention that connects your files, web pages, tasks, emails, & more.

Hook’s nimble context-sensitive navigator is loved by people who need to focus on project info, such as professors, researchers, lawyers, software developers & creatives.

Hook's Context-Sensitive Window

Hook info to stay in flow.

Hook works with the selected item of the foreground app. You can get a link to the current item, “hook” (link) it to another, open an item you’ve already hooked to it, share it, reveal it in Finder, and more!

Universal 'Copy Link'!

Instantly create and use links to all kinds of information: files, emails, tasks and much more! Paste links in your notes, task lists, or anywhere else where you will need them! Use them to instantly return to the information you need, wherever it is.

Bidirectional Links

Instantly access linked items

After you’ve copied a link, you can ‘hook it’ to another item. A ‘hook’ is a bidirectional link. Next time you invoke Hook on this item, you will see links to everything you have hooked to it.

You’ll also love the `Hook to New` command, which creates a new document in your favorite app, and simultaneously names, stores, bookmarks and hooks the document to the source! So you can navigate back/forth between them, and also find them via Hook’s search. Check out Hook’s many other features.

Why we invented Hook

From a CogSci Apps Corp. co-founder:

Every day, I work with numerous files, emails, web pages, and tasks across multiple apps and projects. Search tools help me access ad hoc information. But I also need to instantly retrieve information relevant to my current focus without searching.

Because most work on a Mac revolves around webs of related resources, we created Hook. It enables you to instantly connect and retrieve related information from your favorite linkable apps.

Hook supplies the missing links.

Hook is a contextual information retrieval tool for macOS.

Hook lets you use your favorite apps together, bringing up relevant resources when you need them.

Be nicer to your network: share Hook links

It’s a hassle to receive an email asking you to edit a file, only to have to dig around iCloud, Dropbox, or a Git folder to find the right one. With one Hook command (⌘C), you can instantly create a shareable link that reveals the specified file on the recipient’s Mac. You can even send a link to a prior email that, when clicked, opens the email on their Mac (without going through the web). It’s like magic, and they’ll love you for it. Learn more.
