Extract Text from Images with Telegram Bot & OCR Tesseractjs
Last edited 58 days ago
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.
-
Connect Telegram Bot: Configure the Telegram Trigger node with your Telegram bot.
-
Bot Token: Add your Telegram bot token to the Send Message node to send replies.
-
Deploy & Test: Activate (deploy) the workflow and send an image to your Telegram bot to test.
