FAQ
What is Preptin?
Preptin is an AI prep intelligence layer for coding interviews. It turns real submissions into readiness signals, helps diagnose weak patterns, schedules revision, and points you toward the next useful problem instead of another generic list.
How does the AI help?
Preptin uses the signals you already create through solving, revision, and progress to surface weak concepts, prioritize reviews, and explain why a next problem matters for readiness.
Which platforms are supported?
We currently focus on major problem-solving platforms such as LeetCode, Codeforces, CodeChef, and GeeksforGeeks. You can view and connect supported platforms from your settings page.
If you want to see how platform connections work, visit Settings.
Can I see my progress publicly?
Yes. Your public profile can show platform connections, recent activity, readiness signals, and proof surfaces so people can quickly understand your prep story.
How do subscriptions and refunds work?
Any paid plan or billing flow will show the terms at the point of purchase. You can also review our Refund Policy for the rules around eligibility and requests.
What if I need help?
If you are stuck, want help with a billing question, or need support with a connection issue, email support@preptin.ai.
Fast questions, short answers.
Does Preptin replace my existing practice sites?
No. Your practice sites are where you solve. Preptin connects and enriches that workflow as the intelligence layer on top.
Do I need to connect every platform?
Not at all. You can connect the platforms that matter to you and keep the rest of your workflow the way you prefer.
Is my data private?
We describe our data practices in the Privacy Policy. In short, we only use the data needed to run the product and improve your experience.
