A refined ChatGPT interface powered by your own API key
Connect your own OpenAI API key so you control model choice, spend and data flow rather than paying a bundled subscription.
Responses stream token by token, keeping long conversations responsive and easy to follow.
Save reusable prompts so repetitive tasks take one click instead of retyping the same instructions.
Dictate prompts by voice and bookmark the conversations or answers you want to return to.
Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
