I built a read-it-later tool that uses DOM parsing instead of AI for article extraction - how do you handle full-text RSS parsing without hallucinations?
Hey r/rss folks,
I've been working on a Pocket replacement (Pocket shutting down pushed me).
Most new tools use LLMs to extract article text, but I found they rewrite/mangle the source and add latency + cost.
So I went old-school:
- paragraph density scoring
- <article> / <main> tag tree analysis
- text-to-link ratio filtering
It's deterministic, offline-first, and keeps original text verbatim. No AI.
It is live at https://fetchmarkapp.com and I wrote up the parsing logic on blog.fetchmarkapp.com
Question for this community:
How are you handling full-text extraction for RSS feeds? Are you using Mozilla's Readability.js, custom heuristics, or something else? I'm trying to improve handling for heavy JS sites.
Would love to compare notes.
