Document Summarizer API: Summarize PDF and Word Files

Hosted on ApyHub

What it does

The Document Summarizer API turns PDF and Word documents into short, readable summaries. Upload a PDF, DOCX, DOC, or ODT file, or send a link to one, and get back a plain-text summary in the length and language you choose.

Pick short for about 20 words, medium for about 60, or long for about 100. Set output_language to get the summary in another language, for example de for German or es for Spanish. English is the default.

Use it to show what a document is about before someone opens it, sort incoming contracts, reports, and research papers, or add one-line descriptions to files in a document library or search index. To summarize plain text or a web page instead of a file, use the AI Summarizer API.

You can start on ApyHub's free tier with no card required.
