Product research for considered purchases · Amazon.de
Buy quality — where it actually matters.
A research agent that ranks options on average monthly cost, flags impossible marketing claims, and tells you when a cheap one is fine. Paid by you, not sellers.
⚠️ v0: results are model estimates — verify specs and price before buying.
Paid by you, not sellers
We take no money from merchants and earn nothing when you buy. That frees the tool to recommend the pricier product — or tell you to buy nothing at all.
Ranked on average monthly cost
Not the sticker price — the total cost of ownership over the product's life. An €80 headlamp that lasts years beats three €20 ones that don't.
A “does quality even matter?” gate
Before any deep research, we check whether the category is safety-critical, health-relevant, or worth durability. If not, we just say “buy the cheap one.”
How it works
Paste a link or name
Drop in an Amazon.de URL or a product title. No scraping, no account juggling.
We find what makes it good
The agent works out the criteria an expert would judge on and flags impossible marketing claims (“30,000 lumens for €20”).
Get a ranked, saved brief
A streamed markdown brief with a clear pick, the monthly-cost maths, and an uncertainty banner — saved to your library.
Honest, transparent pricing
Top up a prepaid balance and each analysis draws it down. The fee is the greater of a €0.30 baseline or 15% of the underlying AI cost — you see the estimated cost before every run, and a failed run is never charged. No subscriptions, no seller money, no ads.
