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.

Validate your startup idea with AI before you build
Submit a business concept and receive an AI-generated report on demand signals, target segments, competitor positioning and overall viability.
Covers the angle of your idea — competing products, differentiation gaps and where the market is crowded.
Flags assumptions that could break the business model, from pricing to distribution, so you can test them early.
Premium reports can be shared with co-founders, advisors or potential investors, making the output a communication asset rather than just notes.
