Everything you need to know about Indexia
Indexia is an AI-powered tool that helps you create professional back-of-book indexes (or other document indexes) quickly and efficiently. It extracts important terms, identifies relationships, and formats your index according to industry standards.

Below is an index of On the Origin of Species, which has received zero human editing.
We offer a full refund within 30 days of purchase, provided that:
- You have not yet exported your index
- You understand that requesting a refund will result in the deletion of your project
To request a refund, please contact us at developers@indexia.tech.
We store the data that you upload to and generate with Indexia on our secure servers. You retain full control: you can delete everything at any time by deleting your index project via the user dashboard.
No. We use third-party AI systems and pay per query so that the providers cannot train on your content or use it to improve their own models.
Currently, we use OpenAI. We plan to add additional model providers in the future.
We charge $0.0015 per token, where one token roughly equals one word of your book. For example, indexing a 60,000-word manuscript would cost about $90.
After uploading your PDF (during project creation), you'll receive a cost estimate — and we won't run any AI processing or store anything until you confirm payment.
If you become a Pro Member at $30/month, the rate drops to $0.0005 per token.
Once you pay:
- We automatically parse your PDF, extract indexable terms, and infer relationships between them.
- You receive a near-complete index in our viewer, which you can refine manually (adding/deleting terms, merging entries, creating cross-references and sub-entries).
- The result is a polished index you can export or publish.
Absolutely. Indexia is designed to deliver a strong first draft, but also to allow full manual editing. You can:
- Add or delete terms
- Merge similar entries
- Create cross-references or sub-entries
- Use our AI assist to spot potential duplicates or similar terms to speed the process
You can export your finished index as a Microsoft Word document or as an .IXML file (which is compatible with software like Cindex). Additionally, you can publish a public, read-only link to the index so collaborators or the public can view it without editing access.
