01 · The work order
Paste the estimate. We'll interrogate it.
Copy-paste from the garage's WhatsApp message, bill photo transcription, or invoice. One item per line, with the price.
02 · Exhibit A — line by line
Every line, under the light.
Fair ranges come from our curated price packs. The marker is your quoted price — anything outside the zone gets flagged. No opinions, just data.
03 · The translator
Plain English, locally.
Local inference · Gemma 2B
One click loads Google's open-weight Gemma 2B into your browser (~1.5 GB, one-time, cached after). Nothing you pasted is ever sent anywhere.
Why it works
Niche data. Open weights. Nothing leaves your machine.
Three decisions that make this a business instead of a demo.
01
Private by default
Estimates carry your number plate, VIN and service history. Cloud AI would ship all of it to a server. Here the model runs in your browser. The privacy boundary is the product.
02
Zero marginal cost
$2 a quote only works when each quote costs nothing. No tokens, no servers, no per-call bills. The unit economics survive contact with reality.
03
Niche over generic
A chatbot guesses at part prices. A curated price pack does the math; the open model only puts it into words. Each does what it's reliable at.
Fair ranges are estimates compiled from market data, not quotes — always confirm with a second garage before disputing a bill. wrenchwise is an information tool, not a mechanic. US price pack is in beta: crowdsourced ranges, verify locally.
