Flowise is a visual platform that lets you build artificial intelligence (AI) agents in a simple way, without needing to program. Through a system of nodes and draggable flows (drag-and-drop), it lets you integrate large language models, tools and external services to create chatbots, intelligent assistants and automated flows. This makes it an ideal solution both for technical professionals and for those just starting out in the world of AI. In this article you'll discover in detail what Flowise is, its importance, how to get started and how to create your own visual AI agents in a practical way.

Why is Flowise important?

• It eliminates the programming barrier: Lets you design smart flows without needing to write code.

• It speeds up prototyping and testing: Lets you build, test and iterate AI solutions quickly.

• Native integration with LLM models: Visually supports models like OpenAI, Cohere, HuggingFace and APIs.

• It facilitates AI education and adoption: Ideal for learning concepts and experimenting in controlled environments.

• Cross-platform compatibility: It's possible to deploy the agents on the web, apps, internal tools and more.

• Automation of repetitive processes: Lets you create agents that save time and reduce manual errors.

Before you start: Prerequisites

• Have a computer with Windows, macOS or Linux.

• Have Node.js installed (version 18 or higher recommended).

• Optionally, an API key from an LLM model like OpenAI or HuggingFace.

• An updated web browser (Chrome, Firefox or Edge).

• Recommended: basic familiarity with automation processes. If you want to learn from scratch, visit the Introduction to Artificial Intelligence Course at Coderhouse.

Step-by-step guide: How to create your first AI agent with Flowise

1. Installing Flowise

   • Open your terminal or command console.

   • Type the following command to install Flowise globally:
     npm install -g flowise

2. Start the Flowise panel

   • In the terminal, run:
     flowise start

   • This will open Flowise at http://localhost:3000

3. Create a new flow

   • Inside the web panel, click New Flow and give your agent a name.

4. Add nodes

   • Drag nodes like LLM (Language Model), Prompt Template, Input and Output to the workspace.

   • Each node represents an action or phase in your conversational flow.

5. Configure the AI model

   • Select the LLM node and configure your API key (for example, from OpenAI or HuggingFace).

   • Choose the model (like gpt-3.5-turbo) and options like temperature and maximum tokens.

6. Define the interaction

   • Use the Prompt Template node to define how the user will interact with your agent.

   • Example: "Answer questions about our product catalog in a friendly way."

7. Connect the nodes

   • Join the nodes by dragging the outputs and inputs to establish the logical flow of the conversation.

8. Test your agent

   • Use the Run button or the test interface to interact with the chatbot and validate its operation.

9. Export, share or integrate your flow

   • Flowise lets you export flows, share them or integrate them into web applications using its API.

4 practical examples of visual agents in Flowise

• Customer service chatbot for e-commerce

  • Inputs: User's question.

  • Flow: Input → Prompt Template (answer frequently asked questions) → LLM (GPT-3.5) → Output.

  • You can customize the prompt: "Answer questions about order statuses, returns and payment methods."

• Social media post generator

  • Inputs: Topic or event of the day.

  • Flow: Input → Prompt Template ("Generate a creative post about {topic}") → LLM → Output.

  • Output: Text optimized for Instagram, Facebook, etc.

• Sentiment classifier for reviews

  • Inputs: Review text.

  • Flow: Input → Prompt Template ("Classify this text as positive, negative or neutral: {review}") → LLM → Output.

  • Use: Automatically analyze customer feedback.

• Personalized learning assistant

  • Inputs: Educational query.

  • Flow: Input → Prompt Template ("Explain this topic in simple terms: {query}") → LLM → Output.

  • Applicable: Automatic tutoring in online educational environments.

Best practices and common mistakes when using Flowise

• Design clear and specific prompts: Improves the precision and coherence of your agent's responses.

• Test with different configurations: Adjust the model's temperature and maximum tokens to see different results.

• Reuse flows: Export and adapt your flows for different use cases.

• Don't forget security: Don't share your API keys and use environment variables whenever possible.

• Frequent error: Leaving nodes unconnected breaks the flow; make sure to join all the nodes correctly.

• Frequent error: Using an unconfigured model or an expired API gives error responses.

• Don't overuse tokens: Requesting overly long responses can make the flow slow or costly.

• Test each change: Verify the behavior after each modification.
