💡 Why Open Notebook?

Solving Real Problems

Traditional Note Apps Are Limited: Most note-taking apps are either too simple for technical users or too complex for everyday use. Open Notebook strikes the perfect balance.

Vendor Lock-in Concerns: Your notes are stored in open formats (Markdown, JSON) ensuring you always own your data.

Lack of AI Integration: While other apps are adding AI as an afterthought, Open Notebook is built AI-first from the ground up.

Target Users

Developers: Code snippets, documentation, project notes
Researchers: Literature reviews, experiment logs, data analysis
Students: Lecture notes, study materials, project documentation
Knowledge Workers: Meeting notes, brainstorming, task management

🛠 Technical Architecture

Built with Modern Technologies

// Example: Plugin API
interface NotebookPlugin {
  name: string;
  version: string;
  activate(context: PluginContext): void;
  deactivate(): void;
}

class AIAssistantPlugin implements NotebookPlugin {
  name = "AI Assistant";
  version = "1.0.0";
  
  activate(context: PluginContext) {
    context.registerCommand('ai.suggest', this.getSuggestions);
  }
  
  private async getSuggestions(text: string): Promise<string[]> {
    // AI-powered suggestions implementation
    return await this.aiService.generateSuggestions(text);
  }
}

Core Technologies

Frontend: Electron + React + TypeScript
Backend: Node.js + Express
Database: SQLite with full-text search
AI Integration: OpenAI API, local models support
Sync: WebRTC for real-time collaboration
