How word counts work

Nexus AI measures AI-generated output in AI words — each word the AI produces counts toward your monthly allowance.
  • Free plan — You receive 500 AI words per calendar month. This resets on the same date each month. Once your allowance is used, you’ll be prompted to upgrade to continue generating content.
  • Premium and Ultimate plans — Word generation is unlimited. You can write as much as you need without hitting a cap or being charged extra.
Word counts apply to AI-generated text only. Editing your own content in the editor, uploading files, or using the Chatbot for short queries does not consume your word allowance.

Payment methods

All payments are processed securely through Stripe. Nexus AI accepts the following payment methods:
  • Visa
  • Mastercard
  • American Express
  • PayPal
Your billing details are encrypted and never stored directly on Nexus AI’s servers — Stripe handles all payment data in compliance with PCI-DSS standards.

Upgrading or downgrading

You can change your plan at any time from your account dashboard:
  1. Log in at app.mynexusai.com.
  2. Navigate to Settings → Billing.
  3. Select Change Plan and choose your new plan.
  4. Confirm the change and update your payment details if required.
Upgrading takes effect immediately — you’ll gain access to the new plan’s features right away, and your billing amount will be prorated for the remainder of the current period. Downgrading takes effect at the end of your current billing cycle. You’ll keep your current plan’s features until the cycle ends, then move to the lower plan.
Downgrading from Ultimate or Premium to Free will remove access to paid features such as the Academic Writer, Plagiarism Checker, Voice Clone, and unlimited AI words. Make sure to export any content you need before the change takes effect.

Cancellation policy

You can cancel your Nexus AI subscription at any time — there are no long-term contracts or cancellation fees. To cancel, go to Settings → Billing → Cancel Subscription inside your dashboard. Your paid plan remains active until the end of the current billing period, after which your account moves to the Free tier. All documents and files you created while on a paid plan are retained in your account after cancellation. You won’t lose your content — you’ll simply be limited to the Free plan’s word allowance and feature set going forward.
