Hook for macOS

Link your research and development

Instantly link and retrieve documents, research, code & other resources. Write, research and develop with your favorite tools enhanced by this CogSci Apps® invention for your cognitive productivity.

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.

Hook to Copied Link

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 and hooks the document! Check out Hook’s many other features.

Why we invented Hook

A message from the CEO

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.

Stay in the zone when writing

Nobody wants to rummage around for documents when they’re on a roll. Stay focused on your writing by letting Hook recall your outline, reference material, notes, images, contact information and more right when you need it. Learn more.

Become a note-taking ninja

Never wonder again about what a specific note is referring to. Use Hook to link notes with supporting data like websites, PDFs, email and nearly any kind of document you can think of. Learn more.

Instantly access any type of project information

Instead of trying to remember to save different files to specific folders and sub-folders, let Hook bring your most important work together. Whether it’s a todo list, email, Dropbox file, photograph, web page or note, Hook makes sure you’ll never lose track of it. Learn more.

Connect anything… to anything!

Hook doesn’t just work with built-in apps, it connects a raft of great apps on macOS such as Scrivener, BBEdit, Sublime Text, TextMate, nvUltra, Marked2, Nisus Writer, PDFPen, Skim, Sketch, OmniGraffle, OmniOutliner, DEVONthink, EagleFiler, Keep It (by Reinvented Software), HoudahSpot, Path Finder, Trickster, LibreOffice, MaiMate, Airmail, Apple Mail, iThoughts X, Tinderbox, TaskPaper, Things, OmniFocus, Word, Excel, Powerpoint and many, many more. Hook links your research and development! Learn more.

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.

More from Markdown

If you love Markdown, you’ll love Hook. Hook lets you instantly create Markdown links to the current file, web page, and more, that you can paste anywhere. Learn more
