n8n- Math Teacher AI on Telegram

Trigger: Listens for new images sent to my Telegram bot.

Fetch: Downloads the image file from Telegram using its file_id.

Convert: Turns the image into Base64 so it’s ready for AI processing.

Describe: Sends the Base64 image to GROQ LLaMA to get a detailed description.

Extract: Pulls only the text from the AI’s response.

Detect & Solve: AI Agent scans the text for math problems, solves them, and creates a custom Veo video prompt.

Format: Structures the math problem, answer, and video prompt in clean JSON.

Setup: Stores API keys, model details, and the generated prompt for Veo.

Generate Video: Sends the prompt to Google Vertex AI Veo to create the teacher video.

Wait: Pauses 1 minute for video generation to finish.

Fetch Video: Retrieves the completed video from Veo.

Convert: Turns the Base64 video into an .mp4 file.

Deliver: Sends the final AI-generated teacher video back to the same Telegram chat.

Note: You can also add WhatsApp node instead of Telegram.

Connect with me on IG if you want to build something similar in n8n.

Cheers 🥂
