Building a self-hosted personal-history tool for my capstone, looking for people who'd be interested

I'm a CS student and for my capstone I want to build a self-hosted tool that takes your own data (starting with a Google Takeout export: browser history, searches, location, YouTube, etc.) and turns it into a browsable history of your life. The idea is that all that data is already there but it's scattered and it's just noise in its raw form. Instead of 200 history entries for a day, the tool would group things into episodes like "spent the morning researching a trip to Japan" or "long focused work session on a project," and you could click into any episode to see the raw stuff behind it. Where I want it to end up: you can actually look back over weeks or months and see how you've been spending your time and living your life. Not as a wall of logs, but as something readable, so you can notice patterns, figure out what a good day actually looks like for you versus a bad one, and use that to change things. Basically a memory and a mirror for your own life, that you fully own and host yourself. Hard rules: fully self-hosted, open source, your data never leaves your machine. Since I'm building it for people like the folks here, I'd love some of you as my actual audience: to tell me if it's useful, what you'd want from it, and to try an early version as beta testers later on. If that sounds interesting, drop a comment or DM. Just seeing if anyone here would want this.
