Search Less. Focus more.

😫: You repeatedly search for information scattered across different apps and folders.

😌: Hookmark puts links to task-relevant information at your fingertips, regardless of where it’s stored.

👉: Stop struggling. Stay focused with Hookmark’s contextual links.

It isn’t just fine, it’s just brilliant! … I’m not stopping to think let’s go to Mail, find the email, read this. I’m just thinking: I need this, I’m there. And I’m back again. (William Gallagher)

Hookmark supplies the missing links.

Hookmark’s Context-Sensitive Window

Hookmark 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. Hookmark 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 Hookmark’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 Hookmark 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, Hookmark 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 Hookmark 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 Hookmark’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!

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

Know your bookmarks are private

Hookmark 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 Hookmark 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 Hookmark will instantly create a new note in the note-taking app of your choice, and Hookmark will: name the note, store it, tag it, bookmark it, and link it to the item. Invoke Hookmark 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 Hookmark bring your most important work together. For instance, your todo list can contain links to specific files and emails to work on! Learn more.

Enjoy Hookmark’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☹️. Hookmark file links are much better. Select a file in Finder (or open it), invoke Hookmark (⌃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 Hookmark 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 Hookmark 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 Hookmark, and Copy Link (⌘C) creates a link to that email; send it to others, and when they click that link, Hookmark opens the email on their Mac.

As long as the recipient has the shared file or email, and the free version of Hookmark: 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

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