Re: I kept highlighting on Kindle and never reusing them, so I built a small tool

I had a small but persistent problem.

I read a lot on Kindle and highlight things, but I almost never go back to them. Even when I do, they’re hard to reuse. The highlights are there, but not in a form that’s actually useful.

So I decided to solve this in a simple way for myself.

I built LitMarks.ai, a small Chrome extension.

What it does is straightforward: - open your Kindle notebook page - click one button - export all your highlights as clean JSON with title, author, color, and location

No extra steps. No manual copy-paste. You can drop the output straight into Notion, Obsidian, or your own tools.

This started purely as something I needed. I’m sharing it in case others have the same problem.

I also have some ideas for improving this over time, especially around using AI to make highlights more useful, but for now the focus is keeping it simple and practical.
