Newsdeck.live launches TODAY! - The stories you care about summarised live in TLDR cards

I built Newsdeck (https://newsdeck.live), a news reader that pulls from trusted sources across ~40 topics (AI, science, crypto, gaming, geopolitics, cybersecurity…), distils each story into a 30-second "TL;DR" plus a slightly longer read, and streams them into a live deck that updates as the crawler ingests matches. Two things make it different from a normal RSS reader: A build-your-own 3-column "Tracking Deck" — pin any 3 terms (e.g. "Nvidia", "fusion", "EU AI Act") and get a custom live multi-column feed. The summarization + ranking is an in-house NLP model, not an LLM API call — it learns per-category vocabulary (TF-IDF over the corpus), and I've just added time-decay so it forgets stale vocab instead of ossifying. No per-article API cost, which is what makes a free, always-on aggregator viable. Stack: Spring Boot, server-sent events for the live updates, Cloudflare in front. It's days old and I'm the only user so far, so I'd genuinely love feedback — especially on summary quality and whether the tracking deck is useful or a gimmick. Happy to answer anything about the build.
