Follow-up

“What were the report's main conclusions?”

Ask the document a question instead of skimming for the right section.

AI-generated summaries can contain mistakes. Review the original document before making important decisions.

Understand the document before committing an hour

Reports, papers, and long documents are not equally relevant from beginning to end. Start with the central ideas, identify the sections that matter, and return to the original PDF whenever the details are important.

Build a research library, not a downloads folder

A filename is easy to forget. An idea is easier to remember. TLDRR organizes the PDF with its summary and topics so you can search for what the document was about — even when you no longer remember what it was called.

Reading on the web too? The same workflow applies to articles and web links.

Your documents

When you save a PDF, its content, the generated summary, and the topics TLDRR derives from it are stored in your account so the library keeps working. How that information is handled, retained, and deleted is set out in our Privacy Policy and Terms of Service.
