Credit Usage Rules

Jan 18, 2026

Credit Deduction Policy

Credits are deducted when you use features on the Literfy platform. The rules below explain how credits are calculated and charged.

Paper Search
• Credits are charged per data source.
• Each selected data source costs 2 credits per search.
• The number of results returned does not affect credit usage.

Outline Generation
• Outline generation costs a fixed 2 credits.
• Credit usage is independent of the number of papers selected.

Literature Review Generation (Tiered Pricing)

Literature review generation uses a progressive tiered pricing model.
This means different ranges of papers are charged at different rates, and the total cost is calculated cumulatively, not by a single flat rate.

Pricing Tiers

Number of Papers Price per Paper
1–20 papers 2 credits per paper
21–50 papers 1.5 credits per paper
51–100 papers 1 credit per paper
101–200 papers 0.5 credits per paper

How the Calculation Works
Credits are calculated by adding the cost of each tier step by step.

Example: 50 papers
• First 20 papers: 20 × 2 = 40 credits
• Next 30 papers: 30 × 1.5 = 45 credits
• Total: 85 credits

Example: 100 papers
• First 20 papers: 20 × 2 = 40 credits
• Next 30 papers: 30 × 1.5 = 45 credits
• Next 50 papers: 50 × 1 = 50 credits
• Total: 135 credits

Example: 200 papers
• First 20 papers: 20 × 2 = 40 credits
• Next 30 papers: 30 × 1.5 = 45 credits
• Next 50 papers: 50 × 1 = 50 credits
• Next 100 papers: 100 × 0.5 = 50 credits
• Total: 185 credits

Important Notes
• Minimum number of papers: 5 papers (minimum charge applies)
• Maximum number of papers: 200 papers
• Credits are deducted once, even if multiple AI models are used to generate alternative versions.

Credit Deduction Timing
• Credits are deducted when a task starts.
• If a task fails due to a system error, credits will be automatically refunded.
• If credits are insufficient, the task will not start and no credits will be deducted.
