Chat with any chapter
Every answer comes straight from the chapter.
Students ask a chapter anything and get an answer grounded in that chapter — citing the page it came from, in the language they think in. No open-web guessing, no drifting off the syllabus.
For any spontaneous process, the total entropy of an isolated system never decreases. Heat flows, of its own accord, only from a hotter body to a colder one — never the reverse — and no cyclic engine can convert heat fully into work.
Entropy never decreases in an isolated system — heat always flows hot → cold on its own. For boards, anchor it to the Kelvin–Planck statement and one worked Carnot example.

How grounding works
Anatomy of a grounded answer.
Every reply follows the same path — from the page in the book to a cited answer the student can verify.
- 01
It reads the chapter
The tutor only sees what this chapter contains — the transcript, notes, and text the teacher added. Nothing from the open web.
§4.2 — The Second Law · p. 13For any spontaneous process, the total entropy of an isolated system never decreases.
- 02
The student asks
A plain question, in any language. The tutor answers at the level the student needs — boards prep, a quick recap, or a worked example.
Explain the second law like I’m prepping for boards. - 03
The answer cites its source
The reply names the section and page it drew from, so a student can turn back to the book and check it — and a teacher can trust it.

In the conversation
Six ways students study with it.
Each one stays inside the chapter — a follow-up away, no new prompt to learn.

For teachers and institutes
Why grounding is the point.
A general chatbot will answer anything. A grounded tutor answers from what you taught — and shows its work.
Stays inside your syllabus
The tutor answers from the chapter, not the open web — so students don’t get pulled past what you’re teaching this term.
Every answer cites its source
Each reply names the section and page. A student can verify it against the book; a teacher can trust what’s being taught.
You choose the material
Grounding comes from the chapter content you add — transcripts, notes, text. Change the material and the answers follow.
Join the waitlist
Give every chapter a tutor that stays on the page.
