Flow description

Purpose and benefits

Overview

This workflow automates the process of generating a YouTube video title, description, and hashtags based on the content of any given URL. The primary goal is to support video creators and marketers by quickly creating engaging and SEO-friendly YouTube descriptions that are tailored to the product or topic found on the input page. The workflow leverages large language models (LLMs) to analyze page content and craft relevant descriptions in the same language as the source material.

Step-by-Step Process

  1. User Interaction & Welcome Message

    • When the chat is opened, a trigger node (ChatOpenedTrigger) activates.
    • A welcome message is displayed to the user via a MessageWidget, explaining the tool’s purpose: transforming any webpage URL into a compelling YouTube description.
    • The welcome message is then displayed in the chat interface using the ChatOutput node.

  2. User Submission

    • The user enters a URL through the ChatInput node.

  3. Content Retrieval

    • The entered URL is passed to the URL Retriever node.
    • This node fetches and extracts the main content from the provided webpage.

  4. Prompt Construction

    • The content retrieved from the URL, along with the original URL itself, is sent to a PromptTemplate node.
    • This prompt template dynamically generates an instruction to the LLM, requesting:
      • A YouTube video title,
      • A description of approximately 500 words,
      • Relevant hashtags,
      • All content should be in the same language as the original page,
      • The full page URL should be included in the description.
    • The context of the prompt is filled in with the extracted webpage content.

  5. AI Generation

    • The constructed prompt is forwarded to a Generator node.
    • The LLM processes the prompt and produces the desired YouTube title, description, and hashtags.

  6. Output Display

    • The output from the generator is finally shown to the user in the chat via a ChatOutput node.
