Flowise
Flowise is an open-source, visual tool for building AI agents and chatbots without writing code. Instead of programming, you drag boxes called "nodes" onto a canvas and connect them — one node for a language model, one for your documents, one for a search tool — so you literally see how information flows. A non-programmer can assemble a working assistant: e.g. a chatbot that answers questions from your own PDFs of lab protocols or papers (a technique called RAG, retrieval-augmented generation). You build and test in the browser, then publish the agent as a chat widget you embed on a site or call from other software. It sits between hand-written code and rigid pre-made apps — more flexible than a fixed chatbot builder, far gentler than coding an agent from scratch. Supports 100+ models, vector databases, and tools.
