# demandex

> Demandex mines community demand for physical products. It classifies Reddit complaint and intent posts across 82 communities into demand signals (replacement-part hunts, unmet needs, willingness-to-pay, repeat failures), clusters them into scored opportunity cards with verbatim evidence and permalinks, and answers ad-hoc demand verdicts for any query. A free honest sample and a free category index let an agent learn the shapes before paying; paid tiers return trending teasers, category lists, full evidence cards, and demand verdicts (7-day cached or live research). Physical products only. Evidence is quoted public Reddit posts with provenance (subreddit, upvotes, permalink). Informational only — not a guarantee of any business outcome.
