Contact UsAll self-serve plans are a flat monthly fee for a fixed character quota — not metered per-character billing. Unused quota does not roll over. Manage or upgrade your plan anytime from your dashboard. Education organizations may request additional discounts.
Every plan — including Free — includes part-of-speech tags and semantic-component glosses correctly localized into Chinese, English, Japanese, Korean, Vietnamese, Thai, Indonesian, Russian, Spanish, French, German, Portuguese, and Arabic, using each language's own standard grammatical terminology. Long-form fields (etymology explanations, example sentences) currently only exist in Chinese and English upstream and fall back accordingly for the other 11 languages — see the API docs for the exact breakdown.
