Plans in detail
Rolling renewal
Each plan gives you a number of corrections and rephrasings per period. Your credits renew automatically: every 24 h on Free, 16 h on Standard, 12 h on Premium and Platinum. No midnight queue: credits refresh based on your last use.
Emergency top-up
Need more before the end of your period? Subscribers get emergency top-ups: one click that instantly resets your counters. Standard gets 1 top-up per week, Premium 3, and Platinum 7. Included in the subscription.
Multi-rephrase
Available from the Standard plan, this feature lets you click a specific sentence in your text to get 3 rephrasing variants, instead of rewriting the whole text. Ideal for polishing a paragraph without touching the rest.
14-day free trial
All paid plans include a 14-day free trial, no commitment. Try the extended quotas, multi-rephrase and top-ups. Cancel anytime if it is not for you.
Frequently asked questions
How does Grammatikai work?
Grammatikai uses advanced language models to analyze your text in real time, detect spelling, grammar and punctuation errors, and suggest rephrasings that match the tone you choose.
Is my text private?
Yes. Your text is never stored, nor used to train models. Each request is handled in isolation and deleted immediately after.
Can I use Grammatikai without signing up?
Yes, you can try the demo directly from the homepage without signing up. The free plan, however, requires creating an account.
Which languages are supported?
Grammatikai supports 40 languages, from English to Thai, including Japanese, Arabic, Korean and Swahili. The same list applies to correction, rephrasing and translation.
