What can 100 Credits do?

Each amount assumes all 100 Credits are spent on that one use. Cache discounts let you read more.

Reading prices by language
  • Mandarin and English voices: 0.007 Credits per Chinese character; 0.002 Credits per other character, including letters, digits and punctuation. Spaces are free. Word cards also use your chosen voice and are charged.
  • Cantonese, Japanese, Korean, German, French, Spanish, Portuguese, Italian and Indonesian voices: 0.02 Credits per non-whitespace character.
  • A server cache hit requires matching text, language and voice. It costs 10% of the normal charge, rounded up to 0.001 Credits per request.
  • For languages without Premium Voice, dictionary audio for words and example sentences on word cards is free.
What if I go offline during generation?
  • Failed generations are not charged.
  • If you were charged before losing connection, retry with the same image soon. Generated results are kept for up to 30 minutes; retrieving one during that period does not incur another charge.
Balance and charges
  • Your balance must be above 0 to start a paid task. One use may take it slightly below 0, which is deducted from your next purchase.
  • When you are not signed in or out of Credits, reading automatically switches to the free system voice.

CNY amounts are calculated from the largest pack: ¥68 for 2,000 Credits.
