Frequently Asked Questions
How does word-based billing work?
Each plan includes a monthly word allowance. Words are counted from your input text. Your allowance resets at the start of each billing cycle.
What happens if I exceed my word limit?
You can purchase top-up packs for additional words. Top-up words do not expire and are consumed after your included monthly allowance.
Can I upgrade or downgrade my plan?
Yes, you can change plans at any time. Upgrades are prorated, so you only pay the difference for the remainder of your billing cycle.
How do API keys work?
You can create up to 5 API keys per account. Each key can be named for easy identification and revoked at any time from your dashboard.
