This is the home of Groundtruth - a small studio that builds honest Discord bots - and of Priceproof, a free bot that fact-checks “was” prices.

Shops love a struck-through price. Most people never find out whether anyone ever paid it. Priceproof tells you: paste a shop link (or right-click any message that contains one) and you get the real price history and a verdict - Real discount, Smaller than claimed or Not a discount - judged against the lowest price of the 30 days before the sale, the way EU law does it.

What you find here
  • #live-drops - the biggest real price drops we saw, every morning
  • #deal-check - try the bot: paste any shop link
  • #shop-profiles - how much of a shop is permanently “on sale”
  • #status - the bot checks itself against the shops every night and posts the result here, in public
  • #shop-requests and #bugs - tell us which shop to add or what went wrong
What the bot does
  • /check - price history and verdict for any shop link
  • /track - alerts within minutes when the price drops or your size is back
  • /hunt - one wish across hundreds of shops (“nike dunk under 100”)
  • /watch - a whole shop: drops, restocks, new products
  • /deals and /feed - the biggest real drops, by category, daily in your channel
  • /compare, /shop, /proof - cheaper elsewhere, shop trust, an evidence file for complaints

Free. No ads, no affiliate links. What we cannot prove, we do not show.
