+OnlyPrompt is a web application where users can create, publish, discover and interact with AI prompts. Users can edit their profiles, follow creators, like and save prompts, write reviews and browse free or subscription-based prompt cards in a marketplace.
 
 This project is built with HTML, CSS and JavaScript.
 
 ## Special Features
 - 📝 Create, edit and publish AI prompts
-- 🔍 Browse prompts in a marketplace with category, search and price filters
+- 🔍 Browse prompts in a marketplace with category, search and tier price filters
 - 📄 View prompt detail pages with examples, ratings and access states
+- 💎 Create creator subscription tiers and assign prompts to tier levels
+- 🔐 Subscribe to creator tiers to unlock matching and lower-level prompts
 - ⭐ Write reviews with star ratings and comments
 - ❤️ Like and save prompts
 - 👥 Follow and discover other creators
+- 💬 Start chats with creators from the community page and send local messages
 - 👤 Edit user profiles with display name, username, bio and profile picture
 - 🌐 View own and public creator profiles
-- 📱 Responsive layout for desktop and mobile
+- 📱 Responsive layout for desktop and mobile, including a bottom icon navigation on smartphones
+- ♿ Accessibility improvements such as keyboard focus states, skip links, labels, ARIA states and live status messages
 - 🔄 Server communication through a REST API
 - 💾 Shared data persistence with backend and database

+## Local Usage Notes
+- The community page includes a chat button on creator cards. It opens the chat page and starts a conversation with the selected creator.
+- The chats page supports selecting conversations, searching creators through the new-chat button and sending messages.
+- Chat messages are stored in the browser's `localStorage` for the local frontend demo. They are not persisted in PostgreSQL yet.
+- Keyboard users can use `Tab`, `Shift + Tab`, `Enter` and `Space` to navigate links, buttons, filters, tabs and forms.
+- On macOS, full keyboard navigation may need to be enabled in System Settings or the browser settings so that `Tab` also focuses links.
+
 ## Technologies, Libraries, Frameworks
 - HTML5 for page structure
 - CSS3 with Flexbox/Grid for layout and responsive design

 The project uses authentication with a JWT cookie so that protected pages and API endpoints require a logged-in user. User input is validated on the backend for important operations such as registration, profile updates, prompt creation and reviews.
 
 Known limitations:
-- Payment and premium access are simulated and are not connected to a real payment provider.
+- Subscription access is simulated for the semester project and is not connected to a real payment provider.
+- Chat messages are currently stored locally in the browser and are not connected to a backend chat API.
 - User-generated content is displayed in the frontend, so XSS prevention is important. The project avoids intentionally executing user input as code, but further output sanitization would be needed for production.
 - Authentication is implemented for local project use and would need additional hardening for production.
 
 ## Reflection
-A main challenge was connecting static frontend pages with dynamic backend data while keeping the application usable and consistent. During development, the project evolved from demo pages into a connected application with real profiles, prompts, reviews, likes, saves and creator interactions. We learned how important clear API structures, consistent data models and regular browser testing are when multiple pages depend on the same shared data.
