|
|
* Analytics: Content performance tracking and analysis
|
|
|
|
3. **Data Storage Layer**
|
|
|
|
* Vector Database (ChromaDB): Stores embeddings for semantic search
|
|
* Relational Database (SQLite): Stores structured data like user preferences and content metadata
|
|
|
|
4. **External Integrations Layer**
|
|
|
|
* LLM Providers: OpenAI, Google Gemini, Anthropic, etc.
|
|
* Search Providers: Tavily, SerperDev, Exa, etc.

|
|
|
|
The database architecture consists of two main components:
|
|
|
|
1. **Vector Storage**
|
|
|
|
* Uses ChromaDB for storing and retrieving text embeddings
|
|
* Enables semantic search capabilities
|
|
* Stores content in collections for efficient retrieval
|
|
|
|
2. **Relational Storage**
|
|
|
|
* Uses SQLite for structured data storage
|
|
* Key models include:
|
|
- User: Stores user preferences and settings
|
|
- ContentItem: Represents content created by users
|
|
- ContentVersion: Tracks version history of content
|
|
- Analytics: Stores performance metrics for content
|
|
|
|
Content Generation Workflow
|
|
--------------------------

|
|
|
|
The content generation process follows these steps:
|
|
|
|
1. **Input Phase**
|
|
|
|
* User provides keywords, topics, or other input parameters
|
|
* System configures the generation process based on user preferences
|
|
|
|
2. **Research Phase**
|
|
|
|
* Web research is conducted using various search providers
|
|
* Relevant information is gathered and processed
|
|
* Facts are extracted and organized for use in content generation
|
|
|
|
3. **Content Creation Phase**
|
|
|
|
* Content outline is generated based on research
|
|
* Initial draft is created using AI models
|
|
* Final content is refined and polished
|
|
|
|
4. **Enhancement Phase**
|
|
|
|
* SEO optimization is applied to improve search visibility
|
|
* Images are generated or selected to complement the content
|
|
* Metadata is generated for better categorization and discovery
|
|
|
|
5. **Storage Phase**
|
|
|
|
* Content is stored in both vector and relational databases
|
|
* Embeddings are created for semantic search capabilities
|
|
* Metadata is indexed for efficient retrieval
|
|
|
|
6. **Publishing Phase**
|
|
|
|
* Content is formatted for the target platform
|
|
* Publishing options include WordPress, Markdown, and others
|
|
* Content is delivered to the user or published directly
|
|
|
|
Design Principles
|
|
----------------
|
|
|
|
The AI-Writer architecture is built on the following design principles:
|
|
|
|
1. **Modularity**
|
|
|
|
* Components are designed to be independent and interchangeable
|
|
* New AI models and services can be added with minimal changes
|
|
* Functionality is organized into logical modules
|
|
|
|
2. **Extensibility**
|
|
|
|
* The system is designed to be easily extended with new features
|
|
* Plugin architecture allows for custom integrations
|
|
* Configuration options enable customization without code changes
|
|
|
|
3. **Reliability**
|
|
|
|
* Error handling is implemented throughout the system
|
|
* Fallback mechanisms ensure continued operation
|
|
* Logging provides visibility into system behavior
|
|
|
|
4. **Performance**
