Frequently Asked Questions
What is an AI PDF summarizer?
+
Cuflow's AI summary tool reads your uploaded PDFs, articles, and YouTube videos, then generates a clear, structured summary in seconds—extracting key concepts, definitions, and core ideas so you don't need to read every page.
Is there a free AI PDF summarizer?
+
Yes. Cuflow's free plan includes 2 AI summaries per day with support for files up to 600 pages. No credit card required to get started.
What types of documents can Cuflow summarize?
+
Cuflow supports PDFs (up to 2,000 pages on Pro), Word documents, web article links, YouTube video links, and pasted text.
How accurate is the AI document summarizer?
+
Cuflow uses retrieval-augmented generation (RAG), meaning every summary is grounded in your actual document—not generated from general AI knowledge—which significantly reduces inaccuracies.
Can Cuflow summarize multiple PDFs at once?

Yes. The Pro plan allows batch uploads of up to 100 files per session, so you can summarize an entire reading list in one go.
