Extract text from images with Telegram Bot & OCR Tesseractjs

Description This n8n workflow enables users to send an image to a Telegram bot and receive the extracted text using Tesseract OCR (via the n8n-nodes-tesseractjs Community Node). It's a quick and straightforward way to convert images into readable text directly through chat.

How it Works

- The workflow listens for new image messages coming in via the Telegram bot.

- Once an image is received, it downloads the image file from Telegram (which initially arrives as application/octet-stream).

- The image data, now properly identified, is then sent to the Tesseract OCR node to extract the text.

- Finally, the recognized text is sent back as a reply to the Telegram user.

Setup Steps

- Install Community Node: Ensure you have installed n8n-nodes-tesseractjs in your n8n instance.
