Linkable Mac Applications

This document lists apps that we know can be used with Hook, meaning that you can bookmark and hook (bidirectionally link) their items together with Hook. The information results from our testing and/or Hook customers’. (See also : What’s a Linkable App and Why Does Linkability Matter?).

  1. πŸ‘ : The app has reliable automation for linking which is used by Hook. Those apps are the best apps to use with Hook. Linking should work regardless of the language of the app. And their software developers should be commended for supporting linking and automation.
  2. πŸ€” : Hook integrates with the app using UI scripting because the app lacks an adequate API for linking (possibly no API).

PDF Readers

PDF Readers supporting deep linking (to specific pages)

Hook enables you to copy deep links to specific selections in a PDF ! Paste the links and share them anywhere. That means you can send colleagues a link that will open the specific PDF at the specific page and location on the page! Save yourselves time and use these links rather than referring to page numbers/paragraphs in writing.

Shared hook://file/ links require that the file has the same name on both Macs (good for sharing files via: cloud sharing (like Dropbox); email; version control systems; document management systems).

See: Deep PDF Links Take You Right Where You Need to Focus – Hook.

PDF readers supporting “Copy Selection and Link”

See Copy Selection and Link.

PDF readers lacking adequate automation

  • πŸ€” PDFoo supports deep linking, but you’d need to use its Copy Link function. Not as robust or convenient as Hook’s deep links. If they add an API for deep linking we would likely support it. Deep-linking aside, PDFoo works fine with Hook.
  • πŸ€” PDF Expert by Readdle: it lacks automation; however, you can try this script.

Reference management software

  • πŸ‘ BibDesk: Free LaTeX-compatible Mac bibliography manager app BibTex front-end. See Using Hook with BibDesk.
  • πŸ‘ Bookends: The recommended reference manager for Mac users. Copy Link currently returns bookends:// URLs. hook://file/ If you open the PDF in a different app: refer to that app. Normally that’s a hook://file/ URL.
  • πŸ‘ Papers 3 (Readcube, formerly Mekentosj): (uses hook://file links which means even if you stop using Papers, your links will work. It works with PDFs that remain on file system.)
  • πŸ‘ Zotero: (As of v. 124 of integration. However see this forum post for recent issues and a possible fix.)

Web browsers

  • πŸ‘ Brave
  • πŸ‘ Chrome
  • πŸ‘ Microsoft Edge
  • πŸ‘ Opera
  • πŸ‘ Safari

  • πŸ€” Firefox: (English only)

  • πŸ€” Firefox Nightly browser: (English only)

Ebook readers

Diagramming, graphic organizers, mind mapping, images and photos

Email software

πŸ€” Email clients that expose non-standard email IDs

The following three email apps are supported with qualifications. But please note that the email IDs or URLs they expose are not compliant with RFC 5322 – Internet Message Format. This means the links cannot be shared with others and are not guaranteed to work on different Macs – even of the same user. For linking/bookmarking purposes, it is strongly recommended to use other email software than the 3 below.

  • πŸ€” Mailplane – Gmail client app
  • πŸ€” Microsoft Outlook: AppleScript seems to be phasing out of upcoming outlook. Archiving Outlook Exchange emails, or other events [Γ  la Microsoft] may change their IDs
  • πŸ€” Spark by Readdle (Forum topic. This uses Spark’s email links. It is not yet clear whether these emails can be shared, but Spark users report they can be used across devices of the same user.)

Other office apps (spreadsheets, presentations)

  • πŸ‘ JeditΞ©: per forum.
  • πŸ‘ Apple Keynote
  • πŸ‘ LibreOffice (Calc, Writer, Impress, Draw, )
  • πŸ‘ Microsoft Excel
  • πŸ‘ Microsoft Powerpoint
  • πŸ‘ Apple Numbers

  • πŸ€” Apple Contacts : however Apple’s contact IDs are local to the current installation. Unsyncing from iCloud and resyncing can lead Apple to provide different IDs.

  • πŸ€” BusyContacts: (Currently, in English only)

Integration with Microsoft Office requires Office 2016 or Office 365. Hook is not necessarily qualified for Microsoft “Insider Fast Builds”, which are pre-general release builds. Microsoft says those builds are “Best for Insiders who […] don’t mind the bit of risk involved in using unsupported builds.”

Task managers, Project Management, Calendar apps, and Date-Focused note-taking apps



Finder utilities, extensions and cloud storage

Information managers and bookmarking apps

Development and automation tools

Word processors, text editors, note-taking apps and writing utilities

News Readers

News readers are not designed to open URLs. The reciprocal http(s) link back to the copied address will be opened in the default application (typically a web browser)

Media players, Audio-video editors

macOS Utilities (misc)

Other (misc)

Web services

Hook can be used to link any web page to any other resource!

Given its emphasis on linking, for example we will simply pick one of a nearly infinite number of websites with which you can use Hook: Roam Research. Compare Hook 1.4 release notes.

There are electron apps that are merely wrappers around a web app, such as the following where you can simply use the web app. Or you can copy their items’ URLs using the UI of the apps and feed them into Hook using Hook to Copied Link, for instance.

  • Asana
  • Trello

What to do if your favorite app is not listed above as πŸ‘

There are likely many other apps than those listed above that work ‘out of the box’ with Hook that are not mentioned here. We frequently discover new ones. If you know your favorite app works but is not listed here, please let us know.

Apps of type πŸ€” lack an API. That means communicating with them is not as robust. In some cases, Hook simply does not support Copy Link and showing Hooks directly in them (but there are work arounds). Unless Hook just sends such apps keystrokes, as is the case with Apple News, then the interaction is language dependent. So please consider getting in touch with the developer to ask them to add the required API (AppleScript, JavaScript or x-callback-url) support. It’s easy for them to do, and it would be win-win for them and their customers (including yourself).

If your favorite app is not yet linkable, in many cases it is possible for CogSci Apps Corp, or Hook users, to add scripts in Hook’s Scripts preferences to make the app linkable. But if the app is not currently sufficiently scriptable, you may wish to contact the app’s developer, as described here, to request they make their app scriptable (or support the appropriate x-callback-url’s.)

Many Mac apps are discussed on the Hook productivity forum. Please search for your app there.

Language and internationalization

The Hook display language is currently only English. Unless otherwise noted, apps marked as πŸ€” (UI-scripted) cannot yet be controlled by Hook if the macOS display language is not English.

If your macOS language is not listed for your favorite apps and you’d like support let us know.


We are not responsible for third party app developers (including Apple) ceasing to support their software or changing them in ways that make them less helpful for their customers and ours.

The definition of “compatibility” is different for certain applications. For instance, apps like browsers are read-only, so they don’t require a “scripting interface” for creating new objects. News readers and some information managers work differently. News readers return an address (http//: or https://). When accessing web addresses, typically macOS invokes a web browser.
