Add the exact amount of AI feedback credit you want to your account. Minimum $5.

Useful when the fixed top-ups don’t match what you need — a smaller test top-up, an unusual amount that matches your study plan, or more than $50 in one transaction.

What you get:

– The amount you choose, added to your AI credit balance

– About 25 writing or reading comprehension exercises per dollar of credit (less for speaking exercises — audio transcription costs more per request)

– Use it on any AI exercise on the site

– Top-ups always add to your balance — they never reset it

– No time limit on your balance — it sits in your account until you use it

Enter your amount above ($5 minimum) and proceed to checkout. Credit appears in your account immediately after purchase.
