Automate text extraction and summarization across sources

This automation suite extracts text from URLs, PDFs, or raw text inputs, and generates concise summaries using OpenAI's GPT-4.1-mini language model. The system handles different input types seamlessly, with smart PDF processing that attempts direct extraction before falling back to OCR.Space.

The summaries are customizable in length and focus area, and are returned in a clean markdown format that can be easily integrated into various platforms. This AI-powered content summarization tool is designed to help users quickly synthesize large amounts of information from diverse sources, saving time and improving productivity.

How Latenode estimates time and cost

Latenode bills workflow runs in credits: 1 credit = 30 seconds of processing. Minimum charge per run depends on your plan. 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.
