FAQ
Why can't you just search Craigslist for me?
Craigslist's terms prohibit third-party crawling, and we respect that. Instead you paste a listing, or forward your own Craigslist saved-search alert emails — Craigslist does the searching and emails you; we grade what you forward.
How accurate are the grades?
The score is deterministic and explainable — driven by fair-value discount, resale margin, comp quality, and risk flags, never an LLM's opinion. Every report shows a confidence level, and we say 'insufficient data' rather than guess.
Which categories work best?
Bikes, power tools, and gaming gear (PCs, GPUs, consoles) at launch. Other categories return rough context only until we expand.
Is the MSRP always exact?
No — when we estimate MSRP from public data it's clearly labeled as an estimate. All values are estimates with confidence levels, never guarantees.
