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@exhibitx.ai.

We store the data you upload and generate with ExhibitX in our cloud storage (provided by Supabase). 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.

We use both OpenAI and Anthropic. Standard tier indexing runs on OpenAI; Premium and Editorial Review tiers use Anthropic's Claude. You choose your preferred provider when creating a project.

We charge $0.0015 per token, where one token equals roughly one word of your document. For example, analyzing a 300,000-word document (~1,000 pages) would cost about $450.

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.

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. ExhibitX 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 in multiple formats: Microsoft Word (.docx), RTF, LaTeX (.tex), or CDXF/IXML (compatible with professional indexing software like Cindex and Sky Index). Additionally, you can publish a public, read-only link to the index so collaborators or the public can view it without editing access.

Yes! The ExhibitX Developer API lets you upload PDFs, run the full 27-phase AI indexing pipeline, download completed indexes, and export in multiple formats — all programmatically.
