Flip or Flop: Sign‑up Wall Edition
Show HN: Underpriced AI – Snap a photo, get instant resale value with AI
Flippers love AI price checks, hate sign‑up walls, and say 'just use Gemini'
TLDR: An app promises instant resale values and auto-made listings, but commenters warned that sign-up friction and missing countries kill the vibe. Others said they already ask Google’s Gemini for prices, sparking a debate: polished, resale-specific workflow vs. quick free answers on your phone—and why trying it once shouldn’t require signup.
Underpriced AI promises a reseller’s dream: snap a photo, get a price, and auto‑build a listing for eBay or Etsy. But in the comments, the hype hit a speed bump. One user from France tried to sign up and got blocked by the country dropdown—then asked why they couldn’t try one scan before handing over details. That lit the fuse: the community’s biggest mood was simple—let me test‑drive before I give you my info. The other hot take? A shrug and a flex: “Why not just use Gemini and ask ‘What is this worth?’” It turned into a classic brawl: specialized tool with reseller‑specific comps and listing polish vs the quick‑and‑dirty general AI answer you already have on your phone.
Drama highlights: “France left on read” jokes, “boss fight: the country dropdown,” and the eternal meme of “we have Gemini at home.” Fans of Underpriced AI argued that the Deep Analysis flow (multiple photos, comps, pricing tips, and ready‑to‑post listings) beats a one‑off reply. Skeptics countered that in the thrift aisle, speed is king and friction kills the flip. Verdict? The idea slaps, but the community wants instant try‑before‑sign‑up and global onboarding—otherwise, the bargain hunters will tap the free option in their pocket.
