Hey Product Hunt! I'm Perry, and I built WordHub because I was frustrated with how dictionary apps treat words as isolated items. Here's the thing: words don't exist in isolation. "Construct" connects to "destruction" through shared Latin roots. It sits in a semantic network with "build," "create," and "fabricate." Its etymology traces from Latin con- + struere through centuries of language evolution. Understanding these connections makes vocabulary stick. Research on semantic networks in memory (Collins & Quillian, 1969) shows that organizing knowledge as connected graphs produces stronger recall than isolated memorization. WordHub combines three views: Dictionary — the definition and pronunciation you'd expect WordNet — a visual graph of how that word relates to others semantically Etymology — where the word came from and how it migrated across languages The Chrome extension brings this to any webpage. See a word you don't know? Click it. Get the definition, semantic context, and etymology. Save it. Review it later with spaced repetition. I built this for myself first — I'm a non-native English speaker who wanted deeper tools. Now 10,000+ learners use it daily for GRE prep, academic reading, and general vocabulary building. Everything is free. No account required. Data comes from Princeton WordNet, Wiktionary, and CMUDict. Would love feedback — especially on the WordNet visualization and etymology maps.
