Well I'm implementing a LLM based auto summary for each article and other features which focus on usability / readability / tracking for HN users. And this is more specialized and cannot be achieved by other tools.

Hrm. You should pivot to making an Electric Monk.

"The Electric Monk was a labour-saving device, like a dishwasher or a video recorder. Dishwashers washed tedious dishes for you, thus saving you the bother of washing them yourself, video recorders watched tedious television for you, thus saving you the bother of looking at it yourself; Electric Monks believed things for you, thus saving you what was becoming an increasingly onerous task, that of believing all the things the world expected you to believe."

- Douglas Adams.

Perhaps you could teach the LLM to perform the task of enjoying the articles for you too?
