ChatGPT alternative

The ChatGPT alternative that shows its footprint.

Looking for an AI assistant that never trains on your chats and tells you what each one cost? GreenPT gives you the same capabilities with different defaults.

Everything you use ChatGPT for (chat, vision, code, documents, speech) on open-weight models we host ourselves, with the energy and carbon of every request measured, and inputs that never feed a training pipeline.

The case

Why switch from ChatGPT?

ChatGPT is capable. Its consumer plans also default to using your conversations for training, its models cannot be inspected from outside OpenAI, and no energy figure is published per request. GreenPT inverts all three.

  • Your inputs are never used for model training, on any plan

  • Open-weight models we host ourselves, with no external AI API in the loop

  • Energy and carbon measured per request, from GPU hardware and live grid data

  • Reasoning, vision, code, documents, and speech-to-text behind one key

  • Plans from $5.00 a month, against $20 for ChatGPT Plus

What you can do

Everything you came to ChatGPT for, measured.

  • Reasoning

    Multi-step problem solving that understands context, makes connections, and reaches accurate answers, not just plausible-sounding ones.

  • Vision analysis

    Transcribe and analyse images, charts, screenshots and handwriting. Turn visual data into structured insight.

  • Code generation

    Build websites, convert images to JSON, debug across languages. A development partner that explains its work.

  • Multilingual

    Translate, draft, and proof in real time across major European languages, including a Dutch fine-tune.

  • Documents

    Upload PDFs, contracts, briefs. Get summaries, structured data, and answers grounded in the source.

  • Speech-to-text

    High-accuracy multilingual transcription powered by the Deepgram Nova-3 model.

Outcomes

What changes when you switch.

  1. Your team stops feeding sensitive conversations into a training pipeline

  2. Procurement gets a straight answer on data use and retention

  3. Sustainability reporting picks up real numbers instead of estimates

  4. One subscription covers chat, apps and the API instead of three vendors
