Point your phone at any product, packaging, receipt, or restaurant menu. In about three seconds, get a defensible, citable carbon score backed by the largest reference-grade carbon model on Earth — 123 government and institutional LCAs, 200+ peer-reviewed papers from Nature, Science, IPCC, and The Lancet, 215 million-plus scientific data points, two frontier AI models for image recognition. The same datasets EU CSRD, US SEC, CARB, and CBAM regulators use. Every score cited and traceable. The only consumer carbon score with a citation. Zero commercial databases. Zero offsets. Three free scans to start, no card.

How a scan works
Point. Snap. Score. Cite.
You point. Phone at any product, packaging, receipt, menu, or barcode.
Frontier AI sees. Claude Sonnet 4.6 identifies what's in the frame. Hard scans escalate to Claude Opus 4.7. The AI parses; it never invents.
The supermodel computes. 123 government and institutional LCAs and 200+ peer-reviewed papers cross-reference 215 million-plus scientific data points. The same datasets EU and US regulators use to set policy.
Every score is citable. Tap "View provenance" to see every underlying source by name. No other consumer carbon score does this.
The whole thing takes about three seconds. No commercial databases. No offsets. No black boxes.
Tier 1
Standard
$4.99/ month
billed monthly
For the curious. Everyday products scored against 123 government and institutional LCAs and 200+ peer-reviewed papers. Every score cited and traceable. About the cost of a coffee.
For the obsessed. Unlimited history, custom share cards, export anything. For households, researchers, and people who want the receipts on everything they touch.
Three scans on first install. No card. No signup gate. No countdown timer. Long enough to actually try the product — short enough that we have to earn the next click. If the engine doesn't sell itself in three scans, we don't deserve a subscription.
02
Power-tier costs us money
Most scans run on Claude Sonnet 4.6 — fast, accurate, cheap to operate. The hard scans — receipts with 20 line items, an unusual product the catalog hasn't seen — run on Claude Opus 4.7, which is much smarter and much more expensive for us. We don't gate that behind an upsell wall. When you need the better model, you get it.
03
Yearly saves about 20%
Yearly billing saves about 20%. The discount is real — not the inflated monthly that "discounts" to the price it should always have been. We just charge less for the longer commitment, the way every honest subscription should.
04
No offsets. No conflict.
Most consumer carbon apps make their money selling you offsets. We don't. We never have. Offsets are a separate, contested market with its own credibility problems — bolting them onto a measurement product creates a conflict of interest baked into the business model. Carbon Sight has one job: produce defensible carbon scores.
05
The supermodel, in your pocket.
The certification we sell to brands at $99 per SKU pulls from the same engine that runs in your $4.99 app — and that engine is the largest reference-grade carbon model ever built. 123 government and institutional LCAs. 200+ peer-reviewed papers from Nature, Science, IPCC, and The Lancet. 215 million-plus scientific data points. Every score cited and traceable to its source. The same datasets EU CSRD, US SEC, CARB, and CBAM regulators use. The pricing differs because the deliverable differs. The model doesn't.
Built different
Different problem. Different answer.
Most carbon platforms score companies. Most carbon apps estimate your spending. Most product labels grade your food. Carbon Sight scores what's actually on your shelf — anything you can point a camera at, in about three seconds, backed by 123 government and institutional LCAs, 200+ peer-reviewed papers from Nature, Science, IPCC, and The Lancet, and 215 million-plus scientific data points. Every score, cited and traceable. The only consumer carbon score with a citation. The same datasets EU and US regulators use to set policy.

Common questions
Can I share my subscription with my family?
Standard is single-user. Plus and Pro are designed for households and let you share your scan quota with up to 5 family members.
What's a "Power-tier scan"?
When you scan a complex receipt or an unusual product, the app uses Claude Opus 4.7 — a slower but much more capable model. Your free trial uses Power-tier for all 3 scans so you see the best version of the product. Standard, Plus, and Pro users get a monthly quota of Power-tier scans for the cases that need them.
Do I have to pay to use it?
You get 3 scans on first install — no card, no signup gate. After that, pick a tier. There's no perpetual free version.
Can I cancel anytime?
Yes. Cancel in app or by emailing support. You keep paid features until the end of the billing period.
Is my scan data private?
Yes. Scan photos are processed and deleted; we keep the carbon results, not the images. Paid users can choose to sync their history across devices.
