https://rounak.taptappers.club/fitness - this is my personal site (recently re-designed). The Fitness page is the highlight. It's still WIP, so quite a number of things are blank.
I crunched Strava data (the Strava MCP project is incredible, and I ended up contributing to it!) and built myself this fitness hall of fame page (and also rejuvenated the remainder of the portfolio). Almost all of the stuff here is vibe coded, very happy how much I could achieve.
Now that this hosted CC is achieved, next up, I think scheduled workflows would be coming. For example, certain open-source repositories host data files scraped regularly from sources via scheduled GitHub Actions, that could be simplified.
It's a solution to a personal pain point - discovering and getting reminded of all the hilarious & extraordinary knowledge that I keep discovering on Reddit.
I'm surprised no one mentioned Memoet (https://github.com/memoetapp/memoet). It is a much more modern version of Anki - much more open algorithm, REST APIs and universal interfaces and self-hosted control over one's data.
There's the very good tool Hypothes.is for taking notes and highlights. If the Obsidian community can develop a plugin that can obtain the stream of highlights from the Hypothesis API, then I guess that is possible.
PS: The entire thing is built using Claude Code.
