Plans
Chalk Talk is a live whiteboard for seeing ideas, understanding them by feel and imagining what comes next. Ask about anything, out loud or typed, and it draws the graph, the diagram, the map or a simulation you can play with while it explains, step by step. For students, parents, teachers and anyone curious. A plan gives you credits every month, and you only use what you need.
Your credits carry over. Credits you don't use in a month stay on your account for 2 months, so a quiet month is never wasted.

Every plan includes
- A live whiteboard that draws what you are thinking about: graphs, geometry, ray diagrams, circuits, molecules, maps, timelines and worked steps.
- Simulations made for your question, with sliders to try "what if" and watch what changes, and a library of ready-made ones.
- Explanations pitched to you, spoken or written: to your class if you are at school (Class 1 to 12), or to wherever you are starting from.
- Help with your own pages: share a photo or PDF of homework or notes and work through it.
- Quizzes on a topic or a page, marked for understanding, not exact words.
- Your progress: the topics you have worked on, kept with your class and syllabus.
How lesson credits are used
| A typed question, answered and drawn | about 1 |
| A minute of a spoken lesson | about 1 |
| A new simulation, drawn and checked | about 4 |
| Reading a photo of a page | about 2 |
| A quiz of five questions, marked | about 5 |
| A simulation already in the library | almost nothing |
A bigger lesson uses more: a long explanation with a new simulation uses more credits than a quick graph. Your balance shows what is left.

Good to know
- Every account gets 10 free credits once, to try everything.
- A plan renews every month by UPI Autopay or card, and you can cancel any time here: nothing more is taken after that.
- Unused credits carry over: each month's credits last 2 months, so what you don't use this month is still there next month.
- Ran out mid-month? Buy a plan once as a top-up: it adds its credits on top, for 2 months, and does not renew. The credits that run out first are used first.
- Not happy? We refund a payment in full within 14 days. See Refunds.
