Class-wise Breakdown

Foundational (Class 5-8)

Focuses on curiosity and basic systems (Skeletal, Circulatory, Plant Life).

Secondary (Class 9-10)

In-depth study of Cell Biology, Human Anatomy, and Environmental Science. Aligned with ICSE/CBSE patterns.

Senior Secondary (Class 11-12)

High-level concepts including Molecular Basis of Inheritance, Biotechnology, and complex Plant/Animal Physiology. Ideal for Board Exams and NEET/Olympiad foundation.

Why BioNotes?

Visual Clarity: SVG-first approach for diagrams.
Exam Ready: Condensed points, comparison tables, and frequent "Teacher's Tips".
PWA Enabled: Access your notes offline anytime, anywhere.
Modern UI: Clean, glassmorphism-inspired aesthetic that reduces eye strain.

Author & Vision

BioNotes is curated by Titas Mallick, a visionary educator and M.Sc. Botanist (University of Calcutta). With over 10 years of experience, Titas combines biological expertise with modern web technology to make science accessible.

Developer API (Beta)

BioNotes is built as an Open Source project. You can programmatically fetch notes to integrate into your own educational apps or websites.

Getting Access

The API is protected to prevent scraping. To obtain an API_SECRET_KEY, please contact Titas Mallick at send@bionotes.in.

Endpoint

GET https://api.bionotes.in/api/notes

Query Parameters

Parameter	Type	Required	Description
`ts`	String	Yes	Current Unix timestamp (must be within 5 minutes of server time).
`token`	String	Yes	HMAC SHA-256 validation signature.
`slug`	String	No	Path slug for a single chapter (e.g., `Class-10/1_1_Cell_Cycle`). Returns full content + table of contents outline.
`slugs`	String	No	Comma-separated list of slugs to batch fetch specific notes (e.g., `Class-10/1_1_Cell_Cycle,Class-10/1_2_Structure_of_Chromosome`).
`class`	String	No	Filter chapters by class (e.g., `Class-10`). Returns metadata-only by default.
`content`	Boolean	No	Pass `true` with `class` to fetch full content body (e.g., `&content=true`).
`fields`	String	No	Comma-separated list of fields to filter in payload (e.g., `&fields=title,slug`).

Security Protocol

The API uses Dynamic HMAC Binding. Every request must include a ts (timestamp) and a token (signature) generated using your secret key.

Signature Formula: token = sha256(SECRET_KEY + ts + identifier)

identifier is determined as follows (order of precedence):
1. The value of the slug parameter if fetching a single note.
2. The value of the class parameter if fetching notes for a class.
3. The raw value of the slugs parameter if batch fetching specific notes.
4. The string "all" if no specific filter is used.

Response Data Structure

Single Note / Batch Slugs Response:

{
  "title": "Cell Cycle & Division",
  "description": "Standard biological process overview",
  "slug": "Class-10/1_1_Cell_Cycle",
  "content": "# Cell Cycle...",
  "toc": [
    { "id": "introduction", "text": "Introduction", "depth": 2 }
  ],
  "frontmatter": {
    "title": "Cell Cycle & Division",
    "description": "Standard biological process overview"
  }
}

URL Generation (Node.js Example)

const crypto = require('crypto');
const secret = 'YOUR_SECRET_KEY'; // Provided by Titas
const ts = Math.floor(Date.now() / 1000).toString();

// Example 1: Fetch list of Class-10 notes (metadata only, specifying fields)
const classId = 'Class-10';
const tokenClass = crypto.createHash('sha256').update(secret + ts + classId).digest('hex');
const classUrl = `https://api.bionotes.in/api/notes?class=${classId}&fields=title,slug&ts=${ts}&token=${tokenClass}`;

// Example 2: Batch fetch specific note contents
const slugsList = 'Class-10/1_1_Cell_Cycle,Class-10/1_2_Structure_of_Chromosome';
const tokenSlugs = crypto.createHash('sha256').update(secret + ts + slugsList).digest('hex');
const slugsUrl = `https://api.bionotes.in/api/notes?slugs=${slugsList}&ts=${ts}&token=${tokenSlugs}`;

AI Agent & MCP Integration (Beta)

If you are building educational AI agents, tutors, or study assistants, you can integrate directly with the BioNotes semantic search and syllabus database.

1. Claude AI Partner Skill

We package a pre-configured AI Tutor / Teaching Partner skill that outlines curriculum rules, lesson-planning guidelines, revision workflows, and Hugging Face diagram bucket mappings.

Download Skill: bionotes-ai-partner.skill
Installation: Extract or import this skill into your AI agent environment (such as Claude Desktop or custom agents) to guide its tutoring/teaching logic.

2. WebMCP Server (Model Context Protocol)

Our BioNotes Brain MCP is exposed as a WebMCP server over Server-Sent Events (SSE), allowing cloud-based agents (like Claude.ai custom connectors) to execute biology search tools directly.

SSE Connection Endpoint: https://bn-vector-remote-mcp.onrender.com/sse
POST Message Endpoint: https://bn-vector-remote-mcp.onrender.com/messages
Claude.ai Custom Connector Setup:
- Authorization URL: https://bn-vector-remote-mcp.onrender.com/authorize
- Token URL: https://bn-vector-remote-mcp.onrender.com/token

3. Access Token Authorization

For Human Developers: To obtain the static MCP_API_KEY, contact Titas Mallick at send@bionotes.in. This key should be supplied in your HTTP headers as a Bearer token or under the x-api-key header.
For AI Agents: During the Claude.ai custom connector setup, Claude automatically performs the OAuth 2.0 flow using the Authorization URL and Token URL. The server automatically exchanges the authorization code for the correct access token behind the scenes, allowing the AI to use the MCP tools directly without manual token configuration.

4. Text RAG and Image RAG Capabilities

Text RAG: Query our Pinecone vector database using the query_bionotes tool, or ingest our complete parsed text indexes via the public /llms-full.txt endpoint.
Image RAG: Explore structural pathways, node relationships, and labeled anatomical diagrams (e.g. Mitochondria, Heart, Chromosome structures) using the query_image_rag tool. This tool queries the biological graph database hosted on Supabase and returns structured relationships alongside labeled diagram URLs.

Global Curriculum Alignment

BioNotes is structurally mapped to global educational standards. This mapping is automatically injected into every page's JSON-LD schema and <meta> keywords during the build process, giving each chapter a direct, indexed connection to international curricula searched by teachers and educational aggregators worldwide.

A dedicated Curriculum Standards Directory is automatically generated at build time, grouping every aligned chapter by its mapped standard.

When contributing new .mdx notes, include the following frontmatter fields where applicable:

---
title: Cell Cycle and Cell Divisions
description: Comprehensive notes on mitosis and meiosis.
global_standard: "NGSS-HS-LS1-4"
crosswalks:
  - "AQA-GCSE-4.1.2.2"
  - "IB-Biology-1.5"
learning_objectives:
  - "Use a model to illustrate the role of cellular division in the growth and repair of organisms."
  - "Distinguish between mitosis and meiosis in terms of process and biological purpose."
---

Field	Type	Description
`global_standard`	String	The primary international standard this chapter satisfies (e.g., NGSS, AQA, IB).
`crosswalks`	Array	Secondary standards this chapter partially or fully satisfies.
`learning_objectives`	Array	Precise, assessable outcomes the student achieves after studying this chapter.

These fields are entirely optional. Pages without them are unaffected and render with their existing SEO intact.
