Workflow Description: Captcha Solver

Overview

This workflow, titled “Captcha Solver”, is designed to automate the process of solving CAPTCHA images sent by a user. The flow enables a conversational interface where users can upload a CAPTCHA image and receive the interpreted text or code, making it particularly useful for tasks that require scalable and automated CAPTCHA recognition.

Step-by-Step Flow

1. User Onboarding and Welcome Message

• Trigger: When a chat session is opened, the workflow starts with the Chat Opened Trigger node.
• Welcome Message: This trigger passes the session to a Message Widget, which displays a friendly greeting and instructions. The message tells the user:
  “This is a CAPTCHA solver 🤩. In order to assist you, please send me an image 📷 that contains the CAPTCHA you need help with. I will analyze the image and try to solve the CAPTCHA for you. Once you send the image, I’ll do my best to interpret the text or numbers displayed, and provide you with the solution 🧠🔍.”
• Display: The message is then sent to the chat output so the user sees it immediately upon joining.

2. User Input Handling

• Receiving Inputs: The Chat Input node collects user inputs, which may include text and file uploads (such as images).
• File Upload: If the user sends an image file, it is routed to two places:
  • The Prompt Template component, as a reference for prompt construction.
  • Directly to the Generator (AI model), which processes images.

3. Prompt Preparation

• Prompt Design: The Prompt Template node uses the uploaded image as {input} in a dynamic prompt:

  “what you see in the {input} picture, describe it, if it is a CAPTCHA return the code only”

• Contextual Input: The prompt is tailored to instruct the model to only return the CAPTCHA code if present.

4. AI Processing

• Generator Node: The prepared prompt and the uploaded image are passed to the Generator node, which uses a Large Language Model (LLM) with image input capability.
• Interpretation: The AI processes the image and returns a text output, ideally the deciphered CAPTCHA code.

5. Output Delivery

• Response: The result from the generator (the solved CAPTCHA code) is sent to the Chat Output node, where the user sees the answer.
• File Echo: The original image is also routed to the output, ensuring users can confirm which image was processed.

Benefits and Use Cases

• Scalability: The flow automates CAPTCHA solving, reducing manual effort and enabling bulk or repeated processing.
• User-Friendly: With clear onboarding and feedback, users are guided step-by-step without confusion.
• Integration: The use of LLMs for image-to-text conversion means the flow can adapt to many different CAPTCHA types without custom coding.
• Automation: Useful for QA, testing, accessibility, or any context where repetitive CAPTCHA recognition would otherwise be a bottleneck.

Conclusion

This workflow efficiently automates the process of interpreting CAPTCHA images through a conversational interface, leveraging AI for image understanding. It is a scalable solution for anyone needing to process large numbers of CAPTCHAs, integrate CAPTCHA-solving into other automations, or simply reduce the friction of manual entry.
