Automate content summarization across web, PDFs, and databases

This template starts from a webhook that accepts a URL, PDF, or raw text. A website-to-text step loads a URL. OCR Space reads a PDF.

JavaScript cleans raw text. ChatGPT writes a short summary and the webhook responds with that text. Connect OCR Space and put the OCR Space API key on that connection. ChatGPT is a Latenode AI step.

How Latenode estimates time and cost

Latenode bills workflow runtime in CPU seconds. The first 10,000 CPU seconds are free each month, then usage follows pay-as-you-go CPU-second pricing. Plug-and-Play (PnP) AI nodes are billed separately—each PnP token is $1 USD, charged pay-as-you-go at vendor cost plus a small processing fee, with no API keys required.

How it works

1
Trigger

Receive the content

The scenario starts when your webhook receives a URL, a PDF, or raw text.

2
Logic

Extract the source text

A website-to-text step loads a URL. OCR Space reads a PDF. JavaScript cleans pasted text.

3
AI

Write the summary

ChatGPT returns a short summary from the extracted text. ChatGPT is Latenode AI, so you do not paste an OpenAI key.

4
Action

Return the summary

The webhook responds with the summary so the caller can store or display it.

Setup guide

1

Add the webhook

Add a webhook trigger and copy its URL. Send a JSON body with a URL, raw text, or a PDF file.

2

Connect OCR Space

Add an OCR Space connection and paste your OCR Space API key there. Use this path when the payload is a PDF or image.

3

Extract, summarize, and reply

Route URL input through website-to-text, file input through OCR Space, and raw text through JavaScript. Send the extracted copy to ChatGPT, then return the summary on the webhook response. ChatGPT is a Latenode AI node.

Requirements

A webhook caller that can POST a URL, raw text, or a PDF
An OCR Space account and API key stored on the OCR Space connection, if you send files
A summary length and focus you can set in the ChatGPT prompt
