Service terms

The service

Sentence Simplifier provides AI-assisted paraphrasing and English grammar checks. Other topic pages offer explanations and illustrative examples. You remain responsible for reviewing output, verifying facts, and using material you have permission to process.

Paid subscriptions

AI access requires a paid subscription. Monthly access is US$3.99 per month; yearly access is US$40 per year. Subscriptions renew automatically until canceled. Any applicable tax and the final payable total are shown by Waffo at checkout. There is no free trial and no free AI credit allocation.

Both plans share the calendar-month request allowance displayed on the pricing page. Unused requests do not roll over. Failed AI requests do not count against the application allowance. View current plan details.

Cancellation and payment support

You can request cancellation from your account. Cancellation stops renewal and preserves access until the end of the paid period. Use Waffo’s customer portal or payment receipt for payment questions and refund requests. A refund request does not automatically cancel future renewals; cancel the subscription separately if that is your intention.

Responsible use

Do not use the service for unlawful activity, unauthorised access, or abuse of another person’s material. AI suggestions may be incorrect or change meaning. They do not establish authorship, verify research, or guarantee any detector result.

Your account

Keep your credentials private and use an email address you control. A verified email address is required for subscribing and making AI requests. Service availability depends on the configured AI, email, database, and payment providers.
