GreenPT

GreenPT is an AI assistant that does the usual AI things — answering questions, analyzing documents, drafting text, translating, and reasoning through problems — but with a strong focus on sustainability and privacy. It offers a chat interface, a unified API, a no-code chatbot builder called Frida, apps for teams, speech-to-text, and a tool called Honey that shrinks token usage. The pitch is simple: you get the same kind of AI power you'd find elsewhere, but everything runs on European servers powered by renewable energy, and every chat shows you exactly how much energy and CO₂ it used.

What sets GreenPT apart is its transparency. The platform uses open-source models, compresses and quantizes them to reduce energy consumption by 20-30%, and routes tasks to the most efficient model for the job. Your data stays in the EU, it's GDPR-compliant by design, and there's no greenwashing — they show real-time energy and CO₂ figures per conversation. The API is OpenAI-compatible, so developers can plug it in without rewriting code. Pricing starts at €4.50, undercutting ChatGPT and Microsoft Copilot, and there's a 14-day free trial.

GreenPT is best suited for European professionals and businesses that care about data sovereignty, environmental impact, or both. If you're a developer looking for a compliant AI API, a team that wants a private, sustainable chatbot, or just someone who wants to see the carbon cost of your AI use, this is a solid option. It's not trying to be flashy — it's trying to be responsible, and that honesty is refreshing.
