I am the creator of Markie - https://getmarkie.com - a browser extension that uses AI to automatically categorize and assign tags to pages you bookmark.

I think Markie will solve your problem of forgetting about the bookmarks. AI was the way to go for showing bookmark recommendations.

I invite you to try out the free version and see if the auto-categorization works well.

If you are interested, you can check the reddit post for more info -

P.S: Unfortunately we don't have an import feature just yet. I am still figuring out the engineering part of accomplishing it efficiently.

P.S: If I were to introduce an import bookmarks feature, how important is it for you that the imported bookmarks are auto-categorized/tagged? You have ~500 bookmarks and I could use your opinion.
