Questions
Is my document kept or shared?
Your text is stored in your account so you can reopen the report. It enters the comparison repository only if you tick “Add to repository”. You can delete a check at any time.
How are credits counted?
One credit = one word of the document checked. A 10,000-word thesis uses 10,000 credits. Credits never expire. If a check fails, the credits are refunded automatically.
Is the AI-writing score proof?
No. It is an indicator based on stylistic signals, shown with its reasons. Use it to start a conversation, never as sole evidence.
Which languages are supported?
Documents in French and English are fully supported. Documents in other languages are compared against the web too; the interface is available in French and English.
Which payment methods?
MTN Mobile Money, Orange Money and bank cards through Flutterwave. Credits are added as soon as payment is confirmed.
