A website chatbot handles product and policy questions continuously and can be embedded on permitted domains with one line of code. Ragen exposes knowledge to agents through MCP, an OpenAI-compatible API, and a TypeScript SDK. Integrations listed include Google Drive, HubSpot, ClickUp, Fireflies.ai, Google Calendar, Gmail, Slack, Notion, Google Analytics, WooCommerce, Open Mercato, and Rejestr.io; BaseLinker and KSeF are marked coming soon. Ragen Brain organizes documents into knowledge pages, flags contradictions and outdated files, and requires human approval before publishing. File and folder permissions are checked for every answer. Data remains on the customer’s infrastructure, with optional encryption keys and masking for specified identifiers.
