The engine

See what each strength does to a paragraph

Every plan runs the same engine, HIP (Carnegie Mellon, 2026), on our own GPU server. Plans differ by words, text length, strength (Medium, Extra, Max) and versions per rewrite.

Same paragraph, one version each

5 passes, further from the draft: shorter sentences, plainer words, the caution kept.

Remote work is a growing trend, with many businesses needing to change and adapt to it. A 2024 survey of 2300 employees found that 61 of respondents would work on a hybrid schedule. The study found that employees were more productive when working on a hybrid schedule, and managers had less interruptions when they worked from home. However, the study has some problems. It was not representative and relied on self-reporting.

Billing questions

What counts as a word?
Each word of the draft you paste, counted once, whatever the engine. Rewrites that fail on our side are not counted.
What happens when I run out?
The editor tells you how many words are left before you hit the limit. You can upgrade at any time, or wait for the next period.
Can I change or cancel my plan?
Yes. From your account page you can switch plans or cancel. Cancelling keeps your plan until the end of the period you paid for.
Do unused words roll over?
No. Each period starts fresh. Credit packs are valid 30 days from purchase.
When is a credit used?
Only when your plan does not cover a run: no words left this period, a text longer than your plan allows, a stronger rewrite or more versions than it includes. A credit then runs that rewrite with the top limits. Your plan is always used first.
Do you offer refunds?
If something went wrong, write to us within 14 days of a payment and we will sort it out.
