The Problem

EdTech should be built on
knowledge infrastructure

Today, 90% of EdTech teams spend months wrangling curriculum data instead of building learning experiences.

Manually entering every textbook chapter by hand
One API returns the full structured curriculum tree
Building your own search from scratch with Elastic
Vector RAG search available on day one via POST /ai/rag-search
Writing LLM prompts for every AI feature yourself
Summarize, explain, and generate questions in three API calls

How It Works

From zero to AI-powered
EdTech in three steps

01

Get your API key

Register free in 30 seconds. Your key is scoped, rotatable, and tracked in real time.

02

Query the curriculum

Call structured content endpoints or semantic search. All Indian boards in one platform.

03

Ship AI-powered UX

RAG answers, summaries, and quizzes appear in your app. Your users get smarter features.

Capabilities

Every AI feature your
EdTech product needs

One platform, six capabilities. No stitching together five different vendors.

Structured Content APIs

Curriculum data organized as Class → Subject → Chapter → Topic. Every textbook, every board, queryable in milliseconds.

RAG-Powered Search

Hybrid vector + keyword search with HNSW indexes. Source-backed answers, near-zero hallucination.

AI Summarization

Condense chapters, topics, or raw text into crisp, grade-appropriate summaries via one API call.

Explanation Engine

Turn any concept into a student-friendly explanation. Choose difficulty level and style dynamically.

Question Generator

Auto-generate MCQ, short-answer, or essay questions from any topic or content ID. Instant assessment content.

Developer-First DX

OpenAPI spec, playground, SDKs for Python, JS, Go and REST. Ship your feature in under an hour.

Cross-Lingual Search

Search in English, retrieve Tamil, Hindi, or French content. Queries auto-translate to the target language before retrieval.

Curriculum Versioning

Textbooks are revised on multi-year cycles. Editions coexist — consumers get the current one by default and can pin any revision.

Secure Source Viewer

Render the original textbook page in-app or embedded in your product — watermarked per viewer, so any leak is traceable.

Complete-Set Retrieval

"List all poems", "every formula in Chapter 3", "the first poem" — complete, canonically-ordered sets, not a top-k sample. Works across 10 Indian languages.

Examozhi Chat · for students

The study assistant that never makes things up

A conversational tutor built on your real textbooks. It searches the lesson, shows the exact source, shapes the answer to your exam marks — and says “I don't have enough evidence” instead of guessing. Free to start.

Every answer grounded in the textbook — with tappable sources, never invented.
Exam-ready: shape answers to 1, 2, 3, 5… or any mark allocation.
Ask in Tamil, English, Hindi or romanized — answers in the student's language.
An agent that finds, lists and verifies before it answers — and abstains when unsure.

Study With Friends · live

Study together, out loud

Turn any chat into a live study room. Talk over voice — even without an account — ask the textbook together, and everyone sees the same grounded answer, with the exact page, at the same moment. Like a study group, but the textbook is always in the room.

Talk live in a voice room — your friends hear you instantly, nothing is ever recorded.
Ask once, everyone sees the answer — grounded in the real textbook, with the exact page.
See who's in the room, who's talking, and who's typing — it feels like studying side by side.
One tap turns your chat into a shared room. Share the link on WhatsApp; friends just join.

Complete-Set Retrieval

“List all the poems” should return all of them

Enumeration, ordinal and attribute queries are set operations — not similarity samples. Examozhi routes them to a complete, canonically-ordered path that never truncates, in any supported language.
