Split long PDFs into sections using their table of contents

Breaks a long PDF into its individual chapters and sections automatically, using the document's own table of contents.

How the work actually flows

A straight line. Runs once per one per document section.

The problem it solves

You have a long PDF, like a report or manual, and you only need one section of it, but there's no easy way to pull out just that chapter without scrolling through the whole document. Feeding the entire file into an AI tool also gives worse answers than giving it just the relevant part.

Who it fits

Teams building AI search tools or anyone who needs to work with specific sections of long documents instead of the whole file.

How it works

  1. You submit a PDF, either by URL or upload
  2. The document is parsed in detail to extract text and structure
  3. An AI reads the early pages to identify or build a table of contents
  4. The rest of the document is split into sections that match each heading
  5. Each section, with its heading and content, is returned as a separate item
What you get

Long PDFs split into usable chapters

You get long PDFs broken into their individual chapters and sections automatically, using the document's own table of contents.

What you get

A structured set of document sections, each tagged with its heading and level, ready for search or review.

What you need

A Google Drive account, a Chunkr.ai account, and a Google Gemini API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
