Show HN: Papercut – track ArXiv topics, get notified, skim with AI summaries

Hey HN, I follow a few research areas on arXiv but I never had a good routine for keeping up. I'd check when I remembered, fall behind, then try to catch up on a week's worth of papers at once.

I built Papercut so I don't have to think about it. You define the arXiv categories and topics you care about, and the app notifies you when new papers come in. You open it, scroll through a feed, and each paper has style chips for AI summaries - TL;DR, math breakdown, ELI5, methodology, a few others. Helps you decide quickly what's worth a full read. Runs on-device with Apple Foundation Models. No account, no login, no tracking.

iOS only for now, requires iOS 26 for on-device summarization.

What does your arXiv setup look like? I feel like everyone has a different workflow and I'm curious what people here use.
