Train an AI agent on your own data and embed it on your site in minutes
Import a website URL, PDFs, .docx, .txt, .csv files or paste raw text to build the agent's knowledge base.
Schedule agents to retrain so answers stay in sync as your documentation and site content change.
Add a chat bubble or iframe to your site, or connect the agent to your own app through the API.
Let visitors escalate to your support team when AI answers fall short, and collect or qualify leads automatically.

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.
