GreenPT

GreenPT is a privacy-first AI workspace with chat, search, document analysis, an OpenAI-compatible API and speech-to-text. It runs open-weight models on its own infrastructure and reports measured energy use and grid carbon intensity for every request, with plans from $5 per month and a 14-day free trial.

GreenPT is a Dutch AI platform that bundles chat, search, document analysis, an OpenAI-compatible API and a speech-to-text endpoint into one service, with a distinguishing twist: every request reports the energy it consumed and the carbon emitted while producing it. The models are open-weight and hosted on infrastructure GreenPT selects itself, rather than routed to the large AI labs. Conversations are not used for training, and inputs are not retained beyond short-lived operational caching. For US users, processing happens in North America, and the company states it is CCPA-ready by architecture rather than by add-on. The measurement approach is the core of the pitch. Instead of buying renewable energy certificates or quoting annual averages, GreenPT reads power counters from the GPUs handling a request and combines that figure with the live carbon intensity of the grid where those servers sit. The result appears as a running energy and emissions panel inside the chat, so a team can see what its own usage adds up to over a month. The product also leans on model selection and quantized, compressed models to keep each interaction cheaper in energy terms. Beyond plain chat, the lineup includes Frida, a no-code builder for support or internal help assistants that run on private GreenPT infrastructure, a library of task-specific Apps, Honey for trimming token use on prompts, and a transcription API powered by Deepgram Nova. Subscription tiers run from a Starter plan with a daily prompt cap through Pro for individuals to Teams with workspaces, shared prompt libraries and SSO. It suits privacy-conscious organisations, sustainability and ESG teams, public institutions and developers who want an OpenAI-compatible endpoint with reporting attached. The trade-off is that GreenPT is not chasing frontier benchmarks: it competes on transparency, hosting control and price against ChatGPT and Copilot.
