Khata

The student problem

Preparing for HSC means moving between board questions, notes, formulas, revision plans, and explanations. The organizational work can compete with the actual studying.

I started Khata while dealing with that experience myself. The goal is a coherent study environment for Bangladeshi higher-secondary students.

What I worked on

I designed and built the platform around a study toolkit: scheduling, a focus timer, progress, and notes. The broader product includes question exploration, chapter-based help, formula reference, and flashcards.

I also built the launch funnel. The public site reports more than 2,400 waitlist sign-ups; that is a measure of initial interest, not a count of active learners or improved results.

A product decision

The core structure follows a learner’s subject and chapter. Features should help someone return to the next useful study task, instead of making them manage another complicated system.

AI-assisted answers need source support and evaluation. I describe citation support as a product aim rather than promising that an AI system can never make an error.

Current stage

Khata remains pre-launch. The public site introduces the toolkit and planned learning features. A feature description should not be read as a claim that every workflow has been launched or validated with users.

What comes next

The next useful test is whether students can complete real study tasks more clearly and consistently. That means observing the workflow, checking answer quality, and distinguishing expressed interest from sustained use.
