Institutional / project inquiries

If your university, institution, or project is considering larger-scale use, feel free to get in touch.

Credits = pages × document type (printed 2 / standard 4 / high-accuracy 6 — a 2026-only rate passing on the provider's launch discount; normally 12). Proofreading ON doubles it; batch jobs (50% discount) halve it.

The free tier is flat-rate with a fair-use cap. The monthly allowance resets on the 1st (JST) and does not roll over.
