without rebuilding it

THE BRIEF
AI inside an existing app, on a deadline
Books Corporation of India is a textbook publisher with an existing mobile app used by teachers and students across multiple states. When they decided to integrate AI, the constraint was clear: it had to live inside the app they already had. A separate product was too costly, too slow and unnecessary. They also had a hard deadline, everything needed to ship before the start of the new academic session.
Rather than duplicating BCI's book database, I connected all four tools directly to their existing content database via APIs. The AI always works off live, acurate content and nothing in the existing app was touched.
THE PRODUCTS
Four tools. Two user types. One Suite.
Access is role-based from login. Students see only what is built for them and teachers see only what is built for them.
1.
Chat with Book
Students select a class, subject and chapter. The AI opens a chatbot scoped entirely to that chapter's content. It surfaces suggested questions to get started and answers only what is relevant to the selected chapter. Any off-topic question is flagged and redirected back to the material.
2.
Lesson Plan Generator | For Teachers
Teachers select a chapter and the tool generates a complete lesson plan including teaching flow, student activities, assessment methods, time breakdown and materials. If changes are needed, teachers type natural language instructions and the AI revises accordingly. Exportable as a .txt file.
3.
Question Paper Generator | For Teachers
Teachers select multiple chapters and set the total paper marks, the AI generates a structured question paper with mark distribution across question types, plus a complete answer key. Teachers can revise via natural language or edit manually. Downloadable as .txt or .docx.
4.
Worksheet Generator | For Teachers
Generates upto three distinct worksheets per chapter, giving multiple sets of practice, revision or assessment. Each worksheet includes an answer key. Like the other teacher tools, outputs can be refined via natural language instructions and downloaded as .txt files.
RESPONSIBLE DESIGN
Guardrails built in, not bolted on
In an educational setting, accuracy and appropriate use are non-negotiable. The Chat with Book feature has five delibrate constraints:
​
-
Students can only ask 5 questions per session, after which the chat locks for 6 hours preventing over-reliance on the AI.
-
Off-topic questions do not count towards the limit, encouraging students to stay on the chapter content.
-
The AI only answers questions directly related to the selected chapter. Everything else is flagged and redirected.
-
Suggested questions are surfaced on opening, grounding students in the material from the first interaction.
-
Students have no access to any teacher tools which is enforced at login and not hidden in the UI.
Across all four tools, hallucinations are reduced by design. The AI generates content from BCI's own verified book database, not from general internet knowledge.
OUTCOME
Shipped on time, live across multiple states
The BCI AI Educational Suite launched before the start of the new academic session and is now live for registered BCI users in over 300 schools across 4 states. All AI tools went through rigourous testing before release. Usage data is being gathered as the academic year progresses.
LOOKING FORWARD
AI integration does not have to mean starting over. This project shows that meaningful, responsibly designed AI can be added to an existing product, on time, without disruption and without rebuilding what already works. If that is a problem you are trying to solve I would be glad to talk.
