Frequently asked
What counts as one explanation?
One submitted error gets one full explanation (why-it-fails, mental model, idiomatic fix). Re-reading a saved one is free.
Can I cancel anytime?
Yes. Cancel from your account and you keep Pro until the end of the billing period. See the refund policy for details.
Do you offer GST invoices?
Yes — Indian customers get a GST-compliant invoice with your GSTIN on every Razorpay payment.
Is my code stored?
Your error text is processed to generate the explanation. On Pro, you can save entries to your journal; you can delete them anytime. We don't train models on your code.
