Books, notes, questions, and classes stay in one quiet place.

Chapter 3

Interference is a rule for adding waves.

When two coherent waves meet, the displacement at a point is the algebraic sum of their individual displacements.

Constructive interference appears when the path difference is an integral multiple of the wavelength.

Destructive interference appears at odd half-wavelength path differences, reducing the observed intensity.

01 — Method

Not built by AI.Built with teachers.

Teachers review every mode, explanation pattern, and quiz template so answers stay accurate, age-appropriate, and aligned to how students learn.

Shaped by educators

The way we explain a concept comes from how teachers actually teach it, not from what an LLM defaults to.

Refined every week

Teachers review and correct the system's answers across subjects so it gets sharper as you use it.

Built for classrooms

Curriculum, age range, language, and pace are decided by the school that owns the workspace.

02 — How it works

A study loop,not a pile of tools.

The path is deliberately short: open a workspace, read the book, ask in the right mode, then practice or assign from the same system.

01

Open a workspace.

Personal workspaces stay writable. Class workspaces carry school materials, assessments, and member context.

10-A Physics
JEE Prep
Chemistry Lab

02

Read the book.

The PDF reader, notes, highlights, and continue-studying state all stay attached to the material.

03

Ask in the right mode.

Explain gives clarity. Guide Me asks back. Step by Step slows the reasoning down.

04

Practice or assign.

Learners generate self-practice. Teachers build formal assessments for classes.

Serious tools,kept close to the page.

AI study

AI that teaches from the page.

Choose Explain, Guide Me, or Step by Step without leaving the reader.

Inline anchored mode picker

Workspaces

Personal and class workspaces stay distinct.

Learners write in personal spaces. School classes stay managed and protected.

Writable personal, locked class

Quizzes

Practice stays tied to the book.

Practice questions stay tuned to the material learners are reading.

Self-practice, not formal assignment

Assessments

Assessments are formal by design.

Teachers create, review, assign, grade, and control answer visibility.

Assignable, gradable, teacher-owned

Annotations

Notes belong to the book.

Highlights and notes follow the PDF wherever the learner opens it.

Book-linked annotations

04 — For schools

A calm learner surfacewith school controls underneath.

Schools get their own space. Students open the app and see exactly what their class is studying. Teachers run assessments and track every student — without the tech overhead.

Set up your school

See every student's progress

Know which students are keeping up and who's falling behind — before exam day. Class-level and individual views in one place.

AI builds the test from your material

Upload a chapter, get a quiz. Teachers stop spending evenings writing MCQs — the AI drafts it, they approve it.

Assign to your whole class instantly

One click pushes content, assessments, or reading material to every student in a class. No email chains, no shared drives.

Students study what you assigned

Class materials are locked and curated by teachers. Students open the app and see exactly what's meant for them — nothing more.
