Smart answers shouldn't cost the planet. NatureGPT is the calm, beautifully native iOS AI assistant that cuts the carbon and water footprint of every reply — and funds real trees while you chat. Built on iOS 26's Liquid Glass, it feels right at home next to Messages and Notes, and runs on a lean model hosted on 100% renewable European infrastructure. Ask anything. Plant something. — Every reply runs on solar, wind and hydro. No fossil fuels in the chain. — We fund a verified reforestation tree for every 250 messages you send. — A live dashboard shows the CO₂, water and trees you're racking up in real time. WHY NATUREGPT A typical query to a frontier chatbot quietly burns ~4 Wh and ~5 mL of cooling water on a coal-heavy grid. NatureGPT routes you to a lean model on Scaleway DC5 — France's most efficient data center — and pairs every session with Gold Standard / Verra-grade tree credits. The result: roughly 1.5 g of CO₂ avoided and 8 mL of water saved per message, compounding into real, measurable forests. EVERYTHING YOU EXPECT FROM A MODERN AI • Text chat with full Markdown, code blocks and citations • Voice input — tap, talk, send • Image generation and image understanding • Web search with source chips you can tap to verify • Long-term memory that learns your preferences • Multiple conversations, organized in a clean sidebar • Rich attachments — photos, screenshots, documents LIVE IMPACT DASHBOARD Open the dashboard to see: • Trees funded and a 3D forest that grows as you chat • Total CO₂ compensated, in flight-equivalents you can feel • Liters of water spared from data-center cooling • Progress to your next tree, tile by tile SUBSCRIPTION & PRICING NatureGPT requires an active NatureGPT Plus subscription to chat, generate images and unlock the full impact dashboard. A free trial may be offered to new subscribers; if you don't cancel before it ends, your subscription will start automatically at the regular price. • Pricing is shown in-app before you confirm and is charged to your Apple ID at confirmation of purchase • Your subscription auto-renews at the same price and duration unless you turn off auto-renew at least 24 hours before the end of the current period — Privacy Policy: https://koehler-international.com/naturegpt/privacy-policy — Terms of Service (EULA): https://koehler-international.com/naturegpt/terms-of-service Chat smart.

Verdict
