Features

Screencastify offers a robust set of features, including screen and webcam recording, video editing and interactive questions.

Leaving aside the fact that many features are only available for a fee, it's fair to say that it offers a lot of features.

While recording, you can easily add spotlights and draw on the screen. The drawing tools offer a nice range of options, so you should have everything you need:

The subsequent editor also offers many functions where you can cut the video to your needs.

Here is what the basic editor looks like:

It recently also added an AI feature that automatically adds captions, transcripts, titles, and descriptions.

Furthermore, Screencastify offers another video editor when clicking "Edit Video" in the top right corner.

This will open up another editor where you can do some more video editing. Here is how it looks like:

Second editor of Screencastiy

In our opinion, this editor isn’t necessary if you already have your own video editing software, but it could be useful for some people.

We’re not entirely sure if this is just an older version of the original editor. However, we did discover that you can export videos to MP4 for free, thanks to an "Export" button that lets you do so without any limitations.

We’re not certain if this is intentional, but at least it works for us.

8.5

Diigo offers basic features for a highlighter and bookmarking tool.

It works well and we were able to highlight most websites and they were recreated when revisiting them.

The highlighter popup makes it easy to highlight text offering 4 colors. It looks like this:

Highlighter Popup with four colors

We would have wished to have more color options.

Also, note-taking and the tagging functionality are working, but its design does not look appealing.

Notes Editor: Adding notes to your highlight

The dashboard where your highlights are stored works well and gives you an overview of all your highlights.

Performance
7.5

The speed has deteriorated considerably with the latest updates. This is probably because more and more functions, such as the AI function, are being added.

The tool has become slower, and creating links or accessing older videos takes longer than before. Many users have also complained about the performance in the reviews.

8.0

Diigo performs well in terms of highlighting and syncing across devices. The fact that highlights are always synchronized can cause some loading delays.

It's not as fast as other highlighters that use an offline-first approach, but it works reasonably well.

However, the unreliable link creation feature and the simple sidebar outliner design need improvement.

Design
9.0

The design is intuitive and user-friendly. We think that navigation is very intuitive despite the many functions.

7.0

The design fulfills its functionality. The design of Diigo is outdated and could use a modern refresh.

The lack of a nice overview of all your highlights on the page itself means you have to open the dashboard on diigo.com instead.

The dashboard on diigo.com is okay, but other highlighters like Web Highlights have a much nicer user interface.

Value for Money
5.0

As already mentioned, we are somewhat shocked by the limitations of the free version.

Especially if you have used the app in the past and can export videos for free. In addition, even with the starter package for $7, you are limited to 10 exports.

We find that many other providers offer much more for the money.

8.0

The free version of Diigo offers basic features and is fine for most users. The paid plans are reasonably priced and similar to other highlighters.

However, we think other highlighters offer more value for the same price.

Ease of Use
8.5

Screencastify is easy to use, with a minimal learning curve. Even beginners can quickly get the hang of it. However, we find that recent updates have introduced some complexities that are not absolutely necessary for a screen recorder.

7.8

Diigo is fairly easy to use, but the sidebar outliner takes some time to get used to.

You can't see all your highlights on the page itself, so you have to go to the dashboard on diigo.com.

We wish there was a sidebar to quickly access all our highlighted pages, like in the Web Highlights extension.

Security & Privacy
8.0

Unfortunately, an account is required, which in our opinion is not necessary for Screen recorder.

However, Screencastify's privacy policy is very comprehensive and complies with standard data protection practices, including compliance with the GDPR and PCI-DSS certification for payment data. Screencastify takes reasonable security measures but, like all online services, cannot guarantee absolute protection.

7.5

Diigo takes reasonable steps to protect user data. However, since you need an account and your data is stored in their database, absolute protection can't be guaranteed.

We think a highlighter should work without needing to sign up, but this feature is missing in Diigo.

Conclusion

Screencastify was a fantastic tool in the past, and we used to use it daily. Unfortunately, recent updates have made it less user-friendly by hiding key features behind a paywall.

For people who need a wide range of features, the tool is still an option. For others who just want to make a recording every now and then to export a video, Screencastify is unfortunately no longer an option.

Diigo is a handy tool for collecting stuff from the web, like bookmarks, highlights, and notes.


It’s a good deal with its premium plans, but the old-fashioned design and limited highlight colors might be a turn-off.


If you want something that looks nicer and offers more customization, check out alternatives like Web Highlights.
