Chat with your favourite AI models using your own API key
Add your own OpenAI (or compatible) API key and chat with no monthly subscription — you pay only for what the model uses.
Switch between available language models, including GPT-4-class and cheaper options, from a single dropdown.
Edit the system prompt and settings so the assistant matches your tone, language or task.
Have replies read aloud, send images for analysis, and generate images with supported models.

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.
