Open-source platform for building no-code RAG AI chatbots
Create a RAG chatbot by giving a URL to crawl or uploading files; no coding or API plumbing required.
Built on the OpenAI Assistants and Responses APIs, supporting models such as GPT-4o and GPT-3.5 with improved tool calling.
Let the bot query API endpoints with specific parameters and search the web so answers stay current.
SAML/SSO authentication for private employee chatbots, lead capture, file attachments, and chat disclaimers.
The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
