AI chatbots and agents trained on your own content, embedded anywhere with one script tag
Crawl any URL and index pages automatically, upload PDFs and Word documents, paste text, or lock in exact Q&A answers for the questions visitors ask most.
Choose from OpenAI GPT, Anthropic Claude, and Google Gemini models, and switch the model per chatbot at any time without rebuilding it.
Match brand colors, welcome message, chat bubble styling, and suggested prompts so the widget feels native to your site.
Set domain restrictions, rate limiting, and visibility controls so your agent behaves within the boundaries you define.

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.
