Question 1

What is Zidna?

Accepted Answer

You type a question. Zidna answers with a short lesson: a voice explains while the graphs, equations and diagrams are drawn on screen in front of you, step by step. It is closer to sitting with a tutor at a whiteboard than to reading a chatbot reply or searching for the right video.

Question 2

What can it teach?

Accepted Answer

It is built for math and the subjects that lean on it: algebra, calculus, linear algebra, geometry, statistics, physics, and the math behind computer science and machine learning. It works best when you ask about one idea at a time. “Why does the chain rule work?” gets a better lesson than “teach me calculus.”

Question 3

How is this different from asking ChatGPT?

Accepted Answer

A chatbot gives you a wall of text. Zidna shows you the thing. When it explains a derivative, the tangent line moves. When it explains a matrix, the grid transforms. You watch the idea instead of reading about it. And unlike a video, you can stop it at any point and ask about the exact step you are looking at.

Question 4

How fast does a lesson start?

Accepted Answer

Within a few seconds. Zidna writes the lesson one scene at a time and plays the first scene while it is still working on the rest. A full lesson usually runs about ten minutes.

Question 5

Can I ask questions in the middle of a lesson?

Accepted Answer

Yes. The tutor can see what is on screen, so you can pause at any step and ask why, ask for another example, or ask it to slow down. It answers, then the lesson continues. Every lesson is saved. Come back to it later, or start a new one for a new topic.

Question 6

Is it accurate?

Accepted Answer

Mostly, and getting better, but it is still an AI and it can make mistakes. Treat it the way you would treat a good tutor: if a step looks wrong, ask about it. If you are studying for an exam, check the important results against your textbook.

Question 7

Can I try it before paying?

Accepted Answer

Yes. Every new account gets 5 full lessons free, with the tutor included, before you choose a plan.

Question 8

What does it cost?

Accepted Answer

Starter is $10 a month for 45 lessons. Plus is $20 for 100. Max is $50 for 300. All plans include the tutor and your lesson history; expanding concept maps, adding scenes and asking the tutor draw a little from the same allowance. You can cancel anytime and keep access until the end of the month you paid for.
