Ardhi AI

Point your camera at any product. Ardhi tells you what it costs the planet. No barcode database, no cloud lookup, no account. Ardhi runs its own AI models directly on your phone, so it works in any aisle, in any country, with or without signal. HOW IT WORKS 1. Snap a photo of whatever is in front of you. 2. Ardhi identifies the product and reads its packaging, materials and ingredients. 3. You get a 0-5 impact score, a full breakdown, and swaps you can actually buy. SEVEN THINGS IT SCORES - Ingredients and emissions - Packaging and materials - Biodiversity and habitats - Manufacturing and production - Energy, land and water - Transportation and distribution - Company and greenwashing practices Each dimension gets its own score and a plain-English reason, so you can see whether it's the palm oil, the plastic or the shipping doing the damage. No single number hiding the details. SWAPS, NOT LECTURES Ardhi doesn't just tell you a product is bad. Every scan comes with concrete alternatives you could pick up on the same shelf: a refill instead of a bottle, a bar instead of a tube, a certified supplier instead of an unverified one. Tap any suggestion to search for it. Turn on location and suggestions get tuned to what's actually sold near you. PRIVATE BY DEFAULT Your photos never leave your phone. No account, no sign-up, no tracking, no database phoning home. The AI models download once over WiFi and everything after that happens on your device. COLLECT THE ENDANGERED Scans add up to milestones, and milestones unlock illustrated endangered species: Sumatran orangutan, black rhino, pangolin, kākāpō, snow leopard, narwhal and 12 more. Each one comes with a page on why it's disappearing. YOUR HISTORY, SCORED Every scan is saved with its score, so you can watch your habits shift over months instead of guessing. WHY BOTHER Companies respond to what sells. Enough people leaving the worse product on the shelf is the fastest signal there is. Ardhi makes that a two-second decision instead of a research project. BEFORE YOU START The AI models are a one-time download of around 2.3 GB over WiFi. After that, Ardhi works offline. Ardhi's scores are AI-generated estimates from what it can see and infer about a product, not audited lifecycle assessments. They're built to be directionally useful for everyday shopping, not to certify anything. Treat them as a well-informed second opinion.
