Monthly pass

Writing a lot? A 30-day pass is cheaper than packs. You renew it yourself — no auto-charges.

A pass = a batch of humanizers for 30 days, renewed manually. Packs never expire. Pick whatever suits you.

Standard or Premium: where to spend

One balance, two modes. You decide which right before humanizing, based on the text.

Costs 1

Standard

A fast model for everyday work. It strips clichés, bureaucratese and flat rhythm, and leaves your meaning and voice in place.

  • Posts, emails, articles, product cards
  • Liveliness score before and after
  • 3 such rewrites a day, free
Costs 3

Premium

A strong model for when you need the most. It handles style and rhythm more finely, and treats terms and structure with more care.

  • Theses, landing pages, publications, fine style
  • The most alive result
  • When it has to pass on the first try

Honest rules

No auto-charges

You buy a pack once and the humanizers sit in your balance. There's also a monthly pass — but with no auto-charges, you renew it yourself.

Never expires

Purchased humanizers have no deadline. The free 3 texts a day arrive on top every day.

Refund on failure

Humanization failed on our side? The charge comes right back. We don't bill duplicates.

Payment methods

On the site you pay by card, SBP or in USDT. In the Telegram bot, with Stars. Prices are shown in your language’s currency; we charge in USDT/$.

How much does it cost just to check a text?
Zero. Checking for AI is free forever, with no signup and no limits. Only humanization is paid, and it gives 3 free rewrites every day.
Is this a subscription?
Packs are a one-time purchase and never expire. If you write a lot, you can take a monthly pass — it's also without auto-charges, renewed manually.
How is Premium better than Standard?
Premium is stronger: it reworks style more finely and handles complex texts with more confidence. It costs three charges against one. Standard is plenty for everyday work.
How many texts are in a pack?
As many as there are humanizers, if you rewrite with Standard. A pack of 30 is 30 everyday texts, or 10 premium ones. Near 20,000 characters it costs a little more than one.
