Credit usage change and pricing — 1.5 credits per paper or business-plan job from December 9, 2026
We are announcing again on November 9, 2026: from 00:00 Korea time on December 9, 2026, paper and business-plan (BIZ) jobs use 1.5 of your purchased credits per job. The price of one credit does not change, and credits you hold at that moment keep the current rate until used up. Subscription daily allowances, the free trial and document conversion do not change.
What changes
- Paper and business-plan (BIZ) jobs that start at or after 00:00 Korea time on December 9, 2026 use 1.5 purchased credits per job (jobs on V140.7.1 or later; every version we offer today qualifies). Jobs started before then are charged at the current rate.
- The price of one credit does not change. Example: one standard paper job at about KRW 4,100 becomes about KRW 6,150.
- Credits you hold at that moment are used first and keep the current rate (one credit per job) until they are used up.
- Credits are charged and shown in steps of 0.5. There is no rounding.
- Subscription daily allowances (Basic, Pro, Enterprise), the free trial and document conversion (HWP, DOCX, PDF) are not affected.

Failures, refunds and re-runs
- Jobs that fail because of a system error are refunded automatically, as now. A refund made after the effective date returns one job at the new rate (1.5 credits for a standard paper job), so you can run the same job again.
- A re-run is a new job and is charged at the rate in force when it starts.
- Purchase cancellations and refunds follow our Terms of Service and refund policy.
