Compare · GreenPT vs ChatGPT

A cleaner, safer, EU-hosted alternative to ChatGPT.

If your organisation needs a privacy-first AI platform that runs on renewable energy and keeps every byte of data inside Europe, GreenPT gives you a level of control ChatGPT simply doesn't offer.

Both tools are capable AI platforms. Only one is designed from the ground up for organisations that need strict data control and a measurably lower environmental footprint.

Why GreenPT leads

Sustainability isn't a claim. It's a design choice.

  1. Powered by renewables

    All GreenPT servers run on verified renewable energy sources. No offsets, no greenwashing.

  2. Hosted in Europe

    Your data stays within EU borders, fully GDPR-compliant and protected by strict privacy standards.

  3. Optimised for efficiency

    GreenPT uses lighter, quantised AI models that deliver the same performance with a fraction of the energy.

  4. Full transparency

    We openly share where our infrastructure runs, how we measure energy use, and how we keep improving.

Frequently asked questions

Is GreenPT a good alternative to ChatGPT for EU companies?

Yes. GreenPT runs entirely on European infrastructure in France, keeps every input inside the EU, and never uses your data to train models. For organisations bound by GDPR, that data control is the main advantage ChatGPT does not guarantee on its standard plans.

How is GreenPT more sustainable than ChatGPT?

GreenPT runs on 100% verified renewable energy and publishes its efficiency openly: a PUE of 1.25 and a WUE of 0.25, well below industry averages. ChatGPT does not publish a comparable energy mix or per-service environmental metrics, so its footprint stays unverifiable.

Does GreenPT use my conversations to train its models?

No. Your inputs are never used for model training, on any plan. ChatGPT may use conversations for training unless you explicitly opt out, which is why GreenPT is built for GDPR-sensitive sectors that cannot risk their data entering a training pipeline.

How much does GreenPT cost compared to ChatGPT?

GreenPT starts at €4.50 per month for 15 prompts a day with API access, and €17.50 per month for unlimited prompts. ChatGPT Plus is around $20 per month. GreenPT also offers a 14-day free trial with no credit card required.
