All 19 occurrences of "Swara AI" have been renamed to "Swara" across all 10 source files -- the page title, navbar logo, footer branding and copyright, features section, premium CTA, all three testimonials, resource data attributions, and the headers on the practice, roadmap, and resources pages. Zero references to the old name remain.

Let me first understand the current codebase structure thoroughly before building this feature.

Now let me check the existing resources, question data, and what components are available:

Now let me look at the existing resources data and sub-pages:

Now let me check the existing resources page and see how thorough it is:

Now I have a complete picture. This is a big feature that requires:

1. A comprehensive Notes & Learning page with curated notes for all exams
2. An AI chatbot for concept search
3. Searchable concept explorer with free video resources
4. New components and a new page route

Let me set up a task list and start building:

Let me read the AI SDK examples to follow the exact patterns:

I have all the context I need. Let me now build the comprehensive notes page with AI chatbot. First, let me create the notes data file:

Now create the AI chat API route:

Now let me move to task 2 and build the AI chatbot component:

Now move to task 3 -- build the notes page with library, video resources, and concept search:

Now move to the final task -- add navigation links and homepage section:

Now re-read the navbar and add the Notes link:

Now create the Notes & AI section for the homepage:

Now add the NotesSection to the homepage and the StudyChatbot to the main layout:

Now update the footer to include the Notes & AI link:

Now let me add ai and @ai-sdk/react to the package.json:

Now let me also update the hero section to mention the AI chatbot:

Now let me also update the features section to add the AI chatbot and Notes features:

Now update the features grid to handle 8 items (4 columns):

Mark all tasks done:

Here's a summary of everything built:

Notes & Learning Hub (/notes) -- A full-page experience with three searchable tabs:

• Study Notes -- 25+ curated notes from NCERT, topper compilations, and expert sources across Physics, Chemistry, Math, Biology, GS, Quant, Reasoning, English, CS, Legal, and GK -- all filterable by subject and exam
• Video Lectures -- 24+ free video lectures from top YouTube channels (Physics Wallah, Unacademy, Gate Smashers, Drishti IAS, NPTEL, etc.) organized by subject and topic with duration, views, and direct watch links
• Concept Explorer -- 10+ searchable concept cards with definitions, key formulas, related topics, difficulty levels, and study tips

AI Study Chatbot -- A floating chat widget (bottom-right corner) powered by AI SDK 6 with OpenAI that serves as a study assistant for all 60+ exams. It can explain concepts, suggest strategies, recommend free resources, and solve doubts. Quick prompts help students get started immediately.

Homepage Integration -- A new "Notes & AI Learning" section added to the homepage showcasing note previews, a mock AI chat interface, and feature cards. The navbar, footer, features section, and hero description have all been updated to reference the new capabilities.
