I implemented the feedback I got in my last post, have a look :)

Let's go Philipp 🎉! You should be proud, your landing page looks great 🎉.

The thing I like the most is how you anticipate the awkward question, "Why bother with yet another note-taking app?" and answer it confidently and concisely. As someone unfamiliar with spaced repetition, I am not immediately convinced about the benefits, which is okay. I was interested enough to watch the video and learn more.

I was pleased I could pause the video and start from the beginning in Chrome because it auto-played I was reading. When I watched the video, I found it hard to imagine a successful outcome, so I clicked away.

Here is my advice:

• Linking to spaced repetition on Wikipedia is cheating 😋. And it hurts you. For one, you don't want to have an external link on your homepage, as the viewer may never return. Ever heard the quote "don't show people your method, show them the results"? Normally, that quote applies to project work, but it applies here too. Spaced repetition is your method. As an exercise, I would search "Spaced repetition benefits" and explain those benefits on your homepage directly. Cut through the cruft and tell readers what benefits you're enabling.
• Your video is a show and tell, which is reasonable for an early iteration. Ideally, you should be inspiring your readers. Show them how awesome their note-taking world is going to look with Tag My Knowledge. In your copy, you made a promise to alleviate the pain. Prove it in your video. In actionable terms, your video should demonstrate a full database of real-world knowledge and how Tag My Knowledge keeps it all indexable and discoverable. As a bonus, the video could be made more engaging with a simple narrative (for example, traditional note-taking vs Tag My Knowledge), some light editing, commentary (you can talk or annotate), and music.
