Hook for Mac

Replace search with focus.

Replace the frustration of searching your Mac with the pleasure of using contextually relevant links. Use Hook to copy robust links to information on your Mac or elsewhere (files, emails, tasks, PDFs, web pages, etc). Paste them anywhere. Hook automatically stores your links as bookmarks and optionally syncs them in iCloud.

Hook is a unique, powerful, user-friendly CogSci Apps® invention that will change your life.

Hook supplies the missing links.

Hook's Context-Sensitive Window

Contextual computing : psychological flow

Hook works with the selected item of the foreground app. You can copy a link to the item, bookmark it, share it, link it to something else, access linked items, and more. Hook keeps you in “the zone”.

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.

To copy a link to the current item in the foreground app, just invoke Hook’s contextual window (⌃H or with menu bar icon) and use the Copy Link command (⌘C).

Bidirectional Links

Instantly access linked items

After you’ve copied a link to an item, you can ‘hook it’ to another item. A ‘hook’ is a contextual two-way link. You can ‘hook’ an item to as many other items as you want. When you invoke Hook on an item, you see everything you have hooked onto it. Easily navigate back & forth between hooked items.

For instance, navigate between a draft and its outline, your todo list, and sources (PDFs, web pages, etc.)

Automatic Smart-Bookmarking

Find anything you've linked

Other bookmarking apps have 2 major limitations: they can only bookmark web pages; you need to remember to manually add the bookmark. We at CogSci Apps discovered the clearest signal of information relevance: that you copied a link to it!

So, Hook automatically bookmarks whatever you link. Not just web pages, but important items from all your favorite apps: emails, tasks, presentations, spreadsheets, etc. Type ⌘F in Hook for instant gratification. Learn more

Deep PDF Links

Link to specific locations in PDFs—Adaptive and shareable!

Select text in any fully linkable PDF app, use Hook’s “Copy Link” or “Copy Markdown Link”. Paste the link in your notes, todo list, doc-review comments, tasks lists, even in emails. Clicking on the link will (a) open the PDF, and (b) auto-scroll to that specific location in the file! You can even share these links with others: they can open the shared files on their Macs, like magic!

Hook delivers what researchers, lawyers & others have needed since the dawn of PDF! Learn more

Why we invented Hook

From Cognitive Productivity author & cognitive scientist, Luc P. Beaudoin

Every day, I work with numerous files, emails, web pages, and tasks across many apps and projects. Search-tools can help me find information the first time. But I also need to instantly retrieve prior information relevant to my current focus without searching again.

Because most work on a Mac revolves around webs of related resources, we at CogSci Apps invented Hook, which is loaded with completely original information-retrieval features.

Get more out of your favorite apps

Know your bookmarks are private

Hook stores your bookmarks on your Mac. You can sync your data across devices with iCloud or a folder of your choice. Either way, your data are not sent to our servers. Learn more.

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 New (⌘N) on any item (ebook, PDF, email, etc.) and Hook will instantly create a new note in the note-taking app of your choice, and Hook will: name the note, store it, tag it, bookmark it, and link it to the item. Invoke Hook on the original item and you will see a link to your note, and vice versa! 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. For instance, your todo list can contain links to specific files and emails to work on! Learn more.

Hook connects a raft of great apps on macOS such as DEVONthink, Merlin Project, OmniFocus, RStudio, Craft, Sublime Text, OmniOutliner Pro, Curio, nvUltra, Marked2, TextMate, Scrivener, Tinderbox, Bookends, GoodTask, Nisus Writer, PDFPen Pro, Skim, Obsidian, BibDesk, Sketch, OmniGraffle, EagleFiler, Keep It (by Reinvented Software), Things, HoudahSpot, Trickster, LibreOffice, MaiMate, Airmail, Apple Mail,TaskPaper, Word, Excel, Powerpoint, BBEdit, and many more 😊. Hook links your research and development! Learn more.

Enjoy Hook's adaptive links to files too

macOS file:// links are hard to get; they break when you move the file; and you can’t share them☹️. Hook file links are much better. Select a file in Finder (or open it), invoke Hook (⌃H) and Copy Link (⌘C). You’ll get a hook://file/ link. You can move or rename the file without breaking the link. It’s like a Finder alias; but it’s (a) a link; (b) more versatile; and (c) shareable. 😊 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 the Finder, iCloud, Dropbox, or a Git folder to find the file. With one Hook command (⌘C), you can instantly create a shareable link that your recipients can click which reveals the specified file on their Mac! You can even send them a link that opens a PDF they have on their Mac and automatically scrolls to the specific location in that PDF!

Share links to emails too! While an email is open or selected (in Apple Mail, etc.), invoke Hook, and Copy Link (⌘C) creates a link to that email; send it to others, and when they click that link, Hook opens the email on their Mac.

As long as the recipient has the shared file or email, and the free version of Hook: it’s like magic, and they’ll love you for respecting their time. Who knows, maybe they’ll return the favor? Learn more.

Get more out of your other bookmarking software too

Hook Pro can automatically bookmark to Instapaper, GoodLinks and Pinboard. You don’t have to remember to add bookmarks to them. Learn more.

Instantly get Markdown links — to nearly anything

If you use 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. Even create “.hook” files which are like aliases and webloc files, but instead contain a plaintext URL or markdown link to anything (x-devonthink-item://, OmniFocus://, whatever you want!) Learn more.

Enjoy interoperability

We at CogSci Apps are seasoned devs with roots in UNIX who champion interoperability and have built Hook for eternal use. Hook obeys standard macOS rules (no hacks no haxies) and applicable standards. Hook is plaintext friendly. Pro users can inspect and edit integration scripts. You can export/import Hook data. Hook has an automation API so you can access all your links and execute core functions. Learn more.
