Learn a topic in planned sessions that skip what you already know, check yourself by teaching it back, and turn on Learn mode in any Ask conversation to get hints before answers.

On this page

You don't need course files to learn with Ysra. Name a topic and it plans short sessions for you; or turn on Learn mode in any Ask conversation and Ysra tutors you instead of handing you the answer. This page covers both.

Learn a topic#

  1. Open Learn, choose Learn a new topic, and type the topic, for example Fourier series or discounted cash flow. Ysra reads up on the topic first, so this can take a minute. To turn an existing Ask chat into a topic, choose From an Ask chat.
  2. Answer three quick questions. They let the sessions skip what you already know. Leave a question blank if you don't know the answer: that helps too.
  3. Choose Plan my sessions.

Each session follows the same shape:

Step What happens
Explanation Ysra explains the idea at your level, with a drawing or an interactive View when it helps.
Try it You try an exercise and choose Check my answer.
Teach it back You explain the idea in your own words, as to a friend, and choose Send my explanation.

Ysra tells you how you did — Solid., Almost. or Not yet. — and what to look at again. The Topics tab on the Learn page shows each topic you've started and how far you've got: Seen, Practised or Solid.

Learn mode in Ask#

Learn mode is a switch beside the message box in an Ask conversation. With it on, Ysra acts as a tutor:

  • it asks what you've tried, and gives a hint before the answer;
  • it lets you try each step, then shows its solution;
  • it can draw what it's explaining once you've had a guess: choose Draw the picture when a lesson has one.

To get the answer straight away, choose Just tell me.

Where Learn mode
A tutor chat in a notebook On
Any other Ask conversation Off until you turn it on

When hints first is locked#

The owner of a shared notebook can lock Hints first for the people they share it with. When it's locked, you see a padlock next to Hints first, the switch stays on, and Just tell me shows the solution only after you've tried a step.

What it costs#

Topic sessions, marking your answers and Learn mode use credits like any answer in Ask. See Credits and usage.
