Terms of use

Early access

xplain is in early access. Accounts are by invitation, and during early access xplain is free. Features may change, be limited (for example, a number of questions per day) or be taken away while we build it, and the service may sometimes be unavailable. We will tell you before xplain stops being free for you.

Your account

• Your account is for you alone. Keep your password to yourself, and tell us if you think someone else has used it.
• If you are under 16, use xplain only with a parent's or guardian's permission.
• You can stop using xplain at any time, and ask us to delete your account and lessons.

Your documents and questions

What you open, select, say or ask in xplain stays yours. You let us use it to explain it to you and to run xplain, as the privacy policy describes. Only open documents you are allowed to use, for example your own notes, your course materials, or papers that are publicly available.

Using xplain fairly

Please do not:

• use xplain for anything illegal, or to harass or harm anyone;
• try to break, overload or get around the limits of xplain, or reach parts of it you were not given;
• use scripts or bots to send questions, or copy xplain's explanations in bulk to build another service;
• share your account or sell access to it.

We may limit or close an account that does these things, and we will tell you why.

Explanations are made by AI

xplain's explanations, drawings and numbers are written by an AI model as it goes. They are usually right, but they can be wrong or incomplete. Check anything important against your course, your textbook or a teacher, and do not rely on xplain for medical, legal, financial or safety decisions.

Lessons you save

You may keep and share the videos and PDFs you save from xplain, for example with your class or study group. They show that they were made with xplain.

xplain itself

The xplain software, its look and its name belong to us. These terms let you use xplain; they do not give you any other rights in it.

No guarantees

xplain is provided as it is, during early access, without promises that it will always be available, error-free or fit for a particular purpose. As far as the law allows, we are not responsible for indirect losses, such as lost data or lost time, from using xplain. Nothing in these terms takes away rights that the law gives you and that cannot be waived.

Changes

If we change these terms, we will update them here and change the date at the top. For important changes we will tell you in the reader or by email before they apply.
