Description
Random URLs are easy. Useful serendipity is hard.I've built a free (no ads) app for both Android and iOS for users who want to swipe/surf between websites they otherwise would never have thought to find, both with some randomness and some light personalisation to keep the experience satiating. Users can also search the live web for uncovered topics - the results of which are then (subject to moderation) added to the corpus. It's a bit like StumbleUpon was but for the modern user.Curious if any of you have any thoughts on how much personalisation you can add before serendipity becomes just another recommendation bubble?Please do try it out and let me know your thoughts!

Could you build this?
Partial The mobile web/wrapper app is easy to build, but building a clean, curated, and personalized web crawler/discovery engine without serving junk requires a dedicated pipeline.
What it would actually take: The client can be built in Flutter or React Native with WebView containers and swipe gestures. The backend requires a continuous crawler/curator that indexes niche blogs, personal websites, and independent web projects while filtering out SEO spam, paywalls, and malicious scripts. Maintaining high-quality serendipitous recommendations demands algorithmic graph analysis or embedding-based content clustering over millions of web pages.
