Upgrade your plan, boost your band score today!

Grading, analysis and answer pronunciation scoring all draw from one credit wallet. The wallet refills every month; unused credits don't roll over.

• Free: 30 credits/month.
• Writing: Writing uses no credits, plus 30 credits/month for everything else.
• Speaking: Speaking uses no credits, plus 30 credits/month for everything else.
• Combo: nothing uses credits.

What each task costs: see the Compare plans table on the Pricing page.

Out of credits? Wait for the refill date, or buy the plan for the skill you need. Buying a plan mid-cycle does not refill the wallet: credits used and the refill date stay the same.

Yes! AI4IELTS offers a free plan each month with:

• 30 credits shared across Writing, Speaking, pronunciation and Listening/Reading tips
• Writing & Speaking grading
• Skill practice
• In-depth analysis: the topic analysis and vocabulary sections
• Courses: Module 1 of the Writing course and Stage 1 of the Speaking course
• Pronunciation practice

These 30 credits are shared, so you can split them however you like.

The other in-depth analysis sections and the Writing course from Module 2 onwards are part of the Writing or Combo plan; the Speaking course from Stage 2 onwards is part of the Speaking or Combo plan.

No. Writing, Speaking, and Combo plans do not auto-renew.

Your account is upgraded as soon as the payment succeeds, with no activation needed (if you don't see it after 5 minutes, contact support).

Plans run for the duration you chose (1, 3, 6, or 12 months), counted in calendar months from the moment you buy: a 1-month plan bought on 13 October lasts until 13 November. Buying the same plan again while it is still active adds the new time after the current end date. When it expires, your account automatically reverts to the Free plan.

Refund within 3 days from the payment date if you are not satisfied with the service quality. Please contact our support team via Email (support@ai4ielts.com) or Facebook for refund assistance.

Commitment: We commit to a 100% refund if the service does not meet your expectations.

The band it returns is a practice estimate, not an official score.
