Index Any Document: 15 Use Cases Beyond Books
Indexia is known for back-of-book indexing, but the same technology works on any document. If it has text you need to find again, it can be indexed.
An index transforms unstructured text into navigable knowledge. The principles that made book indexes invaluable for centuries apply to legal briefs, email archives, meeting transcripts, and personal journals. AI removes the barrier of time and cost that previously made indexing impractical for most documents.
Here are 15 document types that benefit from indexing—and how Indexia handles each.
Why Index Documents Beyond Books?
Traditional indexing required reading every page, identifying important terms, and manually recording page references. For a 300-page book, this takes 20-40 hours of skilled labor. For a 10,000-page document collection? Impossible.
AI changes the equation. What took weeks now takes minutes. Documents that were never candidates for indexing—because the cost couldn't be justified—can now have professional-quality indexes.
The value proposition is simple: transform hours of searching into seconds of navigation.

How to Index Any Document with Indexia
-
Upload your PDF — Any document with selectable text works. Scanned documents need OCR first.
-
Set your page range — Skip cover pages, table of contents, or other front matter you don't want indexed.
-
Provide extraction guidance — Tell the AI what matters for YOUR use case. "Focus on legal citations and case names" produces different results than "Extract all person names and organizations."
-
Review and refine — The AI extracts terms; you curate. Merge similar terms, delete irrelevant ones, add cross-references.
-
Export or share — Download as Word, RTF, or Markdown. Or generate a public link to share with others.
What Makes a Document Worth Indexing?
Ask yourself:
-
Is it more than 50 pages? Short documents don't need indexes. Long ones become unwieldy without them.
-
Will you need to find specific information again? If it's a one-time read, skip the index. If you'll return to it, index it.
-
Does it contain names, concepts, or references you'll want to locate? The more "findable things" in a document, the more value an index provides.
-
Is it a reference document rather than narrative? Reference materials benefit most from indexing.
-
Will multiple people use it? Shared documents with indexes save everyone time.
If any answer is yes, indexing adds value.
