The workflow extracts the first valid `http://` or `https://` link, fetches the page HTML, removes boilerplate elements, and sends the cleaned text to an OpenAI model. The structured JSON summary is then formatted and sent back to the same chat.\n\n## Setup\n1. Connect a Telegram credential to the **Telegram Trigger** and **Send Summary to Telegram** nodes.\n2. Connect an OpenAI credential to the **OpenAI Model** node (use the credential named **OpenAI account**).\n3. Open the **Configuration** node and adjust the variables if needed.\n4. Save and activate the workflow.\n\n## Requirements\n- A Telegram bot credential.\n- An OpenAI API credential with access to `gpt-4o` or `gpt-4o-mini`.\n\n## Customization\n- Change `openai_model` to switch models.\n- Change `max_page_size` to send more or less text to the model.\n- Toggle `include_raw_url_in_prompt` to include or hide the source URL from the AI prompt.\n\nNeed help customizing?\nContact me for consulting and support : [Linkedin](https://www.linkedin.com/in/doctor-firass/)\n\n# MY NEW YOUTUBE CHANNEL\n\ud83d\udc49 [Subscribe to my new YouTube channel](https://www.youtube.com/@DRFIRASS).
