FAQPage Schema
How do I summarize a PDF or web page URL into a short text output?

You can summarize web pages and local files by passing the URL or document path to the summarization tool. It processes PDFs and web links, returning concise text outputs to reduce manual reading effort.

Can I get JSON output when summarizing a YouTube link?

Yes, you can generate JSON output from YouTube links. The tool supports JSON output mode for machine readability and uses an Apify-based fallback to extract and condense YouTube video content.

Does the summarization tool work with local audio and image files?

Yes, the summarization tool processes local audio and image files. It generates concise summaries for local content including PDFs, images, and audio files alongside standard web URLs.

Do I need an API key to extract content from URLs?

You need a provider API key to summarize URLs. The tool supports configurable models and optional fallback extraction services like Firecrawl or Apify, which require their own specific API keys.

What is the best way to control the length of a document summary?

The best way to control document summary length is using the tool's built-in output length controls. It supports configurable summary lengths and an extract-only mode to retrieve raw URL content without summarizing.

Why use extract-only mode instead of generating a full summary?

Use extract-only mode instead of generating a full summary when you need the raw text from a URL without model processing. This mode retrieves URL content directly, bypassing the summarization step entirely.
