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.
Lifetime desktop AI client that runs on your own API key
Enter an API key from a supported AI provider and start chatting from a native desktop app on Windows, macOS, or Linux, with no monthly chatbot subscription.
A curated set of ready-made prompts for common tasks, plus tone and advanced output settings so you can tune responses without rewriting instructions every time.
Create reusable AI agents and switch between them for different workflows, alongside image generation from inside the same desktop client.
The vendor states chat data is never stored on its servers, keeping conversations on your own device.
