Ecosia AI: green search, with AI on top
Ecosia added two AI features in December 2025:
- AI Overviews, a quick summary with citations at the top of search results, which you can switch off with one click.
- AI Search, a chat mode for follow-up questions, which can add eco tips if you choose.
Ecosia says it uses small models, measures their energy with the public AI Energy Score and Ecologits tools, and avoids energy-heavy features like video generation. It has invested €18 million in renewable energy projects, and its profits still plant trees.
It’s best for what Ecosia has always been: searching the web.
Viro AI: a green AI assistant
Viro AI is built for the things people use ChatGPT for: writing, studying, planning, coding, research and getting through email and tasks. It includes ChatGPT, Claude and Gemini as well as its own model, and connects to more than 40 apps, from Gmail and Google Calendar to Canvas and Notion.
Its green approach is clean power where the AI runs:
- Viro’s own model runs in data centers in Iceland, Norway, Finland and Ireland, on hydro, geothermal and wind, with no offsets. See the data centers.
- ChatGPT, Claude and Gemini run on their makers’ servers; Viro funds new clean energy to match the electricity each message uses, and labels those answers as energy matched.
- Every reply shows its estimated energy.
