AI Credit Terms

1. What Are AI Credits?

AI credits are a virtual currency used to pay for artificial intelligence services in PDF Index Generator. They represent computational resources consumed when using the AI indexing features.

How Credits Work

• Each PDF page indexed using AI consumes credits (cost varies by language and mode)
• Credits are deducted from your account balance only when you confirm an AI indexing operation
• Unused credits never expire and remain in your account indefinitely
• Credits are non-transferable and account-specific
• Credits cannot be exchanged for cash or refunded for cash value

2. Pricing and How Costs Are Calculated

Basic Pricing Rule

For books written in Latin-based languages (English, Spanish, French, German, Italian, etc.):

Word-Based Calculation

If your PDF pages contain more than 200 words per page, the cost switches to word-count calculation:

Non-Latin Languages

For books written in non-Latin scripts (Arabic, Chinese, Japanese, Korean, etc.), costs are doubled:

Why? AI engines require significantly more computational processing power and “tokens” to handle non-Latin scripts. To ensure the same high accuracy and prevent AI errors, these books require double the resources.

AI Mode Costs

• Automatic Mode: Standard pricing (base pages or words ÷ 200)
• Subjects Mode: Standard pricing (base pages or words ÷ 200)
• Categories Mode: Costs more than the other modes. The book must be sent to AI in several smaller requests, and each request costs the same as indexing the book once. So the total cost = Standard pricing × number of AI requests needed. In practice, this usually works out to roughly 2× the standard cost, though it can be higher for very large category lists.

For detailed cost calculations and examples, see our AI Credits System Help Page.

3. Credit Confirmation Before Charging

We protect your account by requiring confirmation before any credits are deducted:

• Before generating an AI index, a confirmation dialog displays the exact number of credits required
• The dialog shows your current balance and remaining balance after the operation
• You can review and accept or cancel at this point with zero cost
• AI credits are only deducted upon index process completion, never before.
• If you cancel, no charges are applied to your account

4. Automatic Credit Refunds (Fair Usage Guarantee)

We guarantee fair treatment if anything goes wrong during indexing:

What Happens if AI Indexing Fails

• If your AI indexing process fails, disconnects, or has errors, you are only charged for pages that were successfully indexed
• Failed pages are automatically refunded to your credit balance
• You receive a detailed report showing exactly which pages succeeded and which failed
• You can retry the process without paying twice for the same pages

Example

If you start indexing a 500-page book and the AI process completes 60% before a connection error occurs:

• You’re charged for 300 pages (60%)
• The remaining 200 pages (40%) are automatically refunded
• You can retry the remaining 200 pages without additional charge
