+# Say It Again
+
+Native Android application for audio transcription with real-time playback sync and vocabulary management.
+
+The idea to create this application emerged one day when the author of this project ([me](https://www.linkedin.com/in/marcel-milka)) was listening to a podcast to practice listening skills and couldn't fully understand the topic. The lack of podcast audio transcription and podcast/transcription-related applications not meeting expectations contributed to the idea of creating software that allows users to transcribe anything by uploading their own audio/video, creating a transcription, and following along with the transcript while listening to the audio with the ability to save unknown words to learn.
+
+**Note:** The application is still under development and lacks several key features.
+
+## Screenshots
+
+![Screenshots of the production-ready features](/docs/Screenshots.png)
+
+## Design
+
+View the UI design on [Figma](https://www.figma.com/design/inkoCgXPCNKRNAPuOllk6P/Say-It-Again-UI?node-id=0-1&p=f&t=SopfZCzkgSRhCpeL-0).
+
+## Features
+
+* Picking audio to transcribe (planned)
+* Audio transcription with a speech-to-text API (planned)
+* Displaying transcription while playing audio with the ability to save vocabulary (planned)
+* CRUD Room database for saved vocabulary (production-ready)
+* Internet connectivity tracker (production-ready)
+* Bulk-exporting saved vocabulary by generating a CSV file with a backend service (production-ready, see [Say It Again Backend repository](https://github.com/MarcelMilka/SayItAgainBackend))
+* Saving a CSV file directly to the device (production-ready)
+* Sending a CSV file to user's email address (planned)
+
+**Minor improvements in the future:**
+* Splash screen with animated content
+* Custom illustrations (the current ones come from [undraw.co](https://undraw.co))
+
+## Modularization
+
+The project was divided into Android modules to improve the overall structure.
+
+* **app** - Main application module with MainActivity and ApplicationClass
+* **common** - Shared models, interfaces, and utilities used across all modules
+* **scaffold** - Application-level navigation and main UI structure
+* **feature:home** - Home screen functionality and UI
+* **feature:saved** - Saved words management, export functionality, and related screens
+* **feature:transcribe** - Audio transcription functionality (currently in development)
+* **localData** - Local database operations using Room, DAOs, and data sources
+* **remoteData** - Network operations, API endpoints, and remote data handling
+* **connectivity** - Network connectivity monitoring and status management
+* **ui** - Shared UI components, themes, and design system elements
