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.

From idea to execution with an AI co-founder
Begin with who you are — how you think and work, what you optimise for and your constraints — so ideas start from fit rather than trends.
Test whether people actually have the problem and are willing to pay, with idea scoring, market demand checks and objective comparisons of alternatives.
Turn what you learned into a coherent plan with a seven-section business plan builder, go-to-market strategy and financial projections.
An AI co-founder that maintains context over time, from identity and idea context to full memory, plus decision checkpoints and ongoing nudges.
