Other AI nodes
LLM chains, extraction, classification, sentiment, summaries and knowledge bases.
Besides the AI Agent, these nodes use a chat model for a single, focused job. Each needs a chat model attached, like the agent.
| Node | Use it to |
|---|---|
| Basic LLM Chain | Send a prompt and get the answer, without tools or memory |
| Information Extractor | Pull structured fields (name, date, amount…) out of free text |
| Text Classifier | Put text into one of your categories; each category gets its own output |
| Sentiment Analysis | Detect positive, neutral or negative tone |
| Summarization Chain | Turn long text into a short summary |
Knowledge base
The Knowledge Base node adds documents to a knowledge base (they're split, embedded and stored) or searches it. Agents read it through the Knowledge Base Tool, so they can answer from your own documents: price lists, policies, FAQs.
App nodes for AI providers
There are also regular nodes for OpenAI, Anthropic, Google Gemini, Mistral, Groq, DeepSeek, Perplexity, Cohere, Hugging Face, ElevenLabs, Ollama and others, for when you want to call a provider's API directly.
