Mossglen keeps an Elo-style estimate of your reading level and turns any page or YouTube video into a lesson that fits: new words marked in place, read-aloud, tap-to-save vocab with spaced review, and a post-read quiz that recalibrates your level.
Hi Product Hunt 👋 solo maker here.
I built Mossglen because of a folder I'm not proud of: 100+ saved articles, zero finished. Not laziness — every one was just above what I could actually read, and I'd burn out three paragraphs in.
Language teachers call the sweet spot "i+1": material slightly above your current level. The problem is nobody can tell you which article is your +1. Graded readers are fake and boring; real articles are a lottery.
So Mossglen measures instead of guessing. It keeps an Elo-style estimate of your reading level — same idea as chess ratings. Every word you tap and every post-read quiz updates it, and rates the article back. Then the whole internet gets filtered through that number: any page or YouTube video becomes a lesson at your level, with new words marked in place and saved words coming back for spaced review inside the sentence where you first met them.
Works for 8 target languages, not just English. The free tier has unlimited reading and word lookups.
I'd love to know: what's sitting unread in your bookmarks right now — and what killed it, time or level?
