Unlock with ProThe problem, in the searcher’s words
Someone about to drop real money on a TV, appliance, car, or other big-ticket item wants to know: is this actually a good price, or am I overpaying? The title of this thread names that exact itch — a 'price confidence' tool for major consumer purchases — but the post itself is just a link to the OP's own demo, with almost no discussion of the actual pain point in the poster's or commenters' own words.
The two replies that exist don't validate the problem — one just points out the post is in the wrong subreddit, and the other pushes back, saying AI already handles this kind of price-checking well and suggesting the OP focus elsewhere. There's no corroboration from other users describing their own frustration with figuring out fair prices.
What the thread shows
This thread shows an OP promoting their own demo with almost no organic problem discussion, and the only substantive feedback is pushback claiming the problem is already solved by AI — this does not demonstrate corroborated demand.
“Good job, but wrong sub.”
“Not to burst your bubble but ai is great at doing this already, I'd focus my effort on something else”
Target customer
Who
Consumers researching a big-ticket purchase (electronics, appliances, vehicles) who want reassurance they're paying a fair price
Context
Not established by the thread itself; inferred only from the post title, since no commenter describes their own purchasing situation or frustration.
What to build
- Price history lookup for a given product/category
- Fair-price score or range based on historical data
- Cross-retailer price comparison
- Price drop / deal alerts
- Simple product search or barcode/URL input
Build note — Would need reliable price-history data sources (retailer APIs, scraping, or partnerships) and enough historical depth per category to generate a credible 'fair price' score — this is a significant data acquisition challenge, especially outside of well-tracked categories like Amazon electronics.
Later, if it lands
Who’s already out there
Tracks Amazon price history and sends price-drop alerts.
Gap: Limited to Amazon listings; doesn't cover major offline or cross-category purchases like cars or appliances from other retailers.
Browser extension that finds coupon codes and compares prices at checkout.
Gap: Focused on discount codes, not a broader 'is this a fair price' confidence score across purchase categories.
Lets users compare prices for a product across multiple retailers.
Gap: Shows current prices side by side but doesn't provide historical trend context or a confidence score for whether the price is genuinely good.
Demand read
The thread contains no statements from users about paying for such a tool, describing costly workarounds, or expressing strong need — demand here is asserted by the OP's product launch, not evidenced by the discussion.
Worth digging into before you build
6 to considerNo idea is a sure thing at this stage — these are open questions worth checking yourself, not a verdict against building it.
Thin Source
Post is a title plus a demo link with only two brief comments; almost no problem discussion to draw from.
Promotional Source
OP is sharing their own live demo app and asking for feedback, indicating manufactured rather than organic demand.
Single Voice
Only the OP frames this as a problem worth solving; no commenter corroborates the pain.
Weak Demand
No willingness-to-pay signals exist, and commenter Degentrics pushes back, saying 'ai is great at doing this already, I'd focus my effort on something else.'
Already Solved
Degentrics's comment suggests existing AI tools already handle this kind of price checking, undercutting the case for a dedicated app.
Unsupported Field
key_quotes and target_customer are weakly supported — the available quotes are pushback/off-topic rather than evidence of genuine user pain.
