Questions

What happens when the trial ends?
You move to the free plan. Every book, word, note and review you have is still there; only the AI features get an allowance of 10 a day. Upgrade whenever you like.
Do I need a card to start?
No. The trial starts the moment you create an account, and nothing is charged unless you choose Pro later.
What does "5 texts at a time" mean?
On the free plan you can keep 5 of your own texts — pasted, uploaded, fetched by link or lyrics — active at once. Archive one and the slot is free again. Books from the catalogue and the sample texts never count.
Can I cancel?
Any time, from the Plan page. Pro stays on until the end of the period you have paid for, then you continue on the free plan.
Is VAT included?
The exact total, including any VAT that applies where you live, is shown by Stripe before you confirm.
