Probly

Data analysis with spreadsheets made simple

Probly is a next-generation spreadsheet application that combines the power of traditional spreadsheets with AI-driven analysis, Python computation, and intelligent document processing.

• Smart Spreadsheet: Full-featured spreadsheet with formula support and intelligent cell suggestions
• Python Integration: Run Python code directly in your browser using WebAssembly
• Data Visualization: Create interactive charts and visualizations
• AI-Powered Analysis: Get intelligent insights and automated trend analysis
• Document Processing: Extract and process data from images.
• Prompt Library: Access predefined analysis templates and save custom prompts

Probly leverages a modern, privacy-focused architecture:

graph LR
    A[Browser] --> B[Next.js Frontend]
    B --> C[Pyodide/WASM]
    B --> D[OpenAI API]
    B --> E[Vision API]
    C --> F[Local Processing]
    D --> G[AI Analysis]
    E --> H[Document Processing]

• Frontend: Next.js 14 with TypeScript and React
• Python Runtime: Pyodide (WebAssembly) for local execution
• AI Integration: OpenAI API for intelligent analysis
• Document Processing: Vision API for extracting data from documents

• Interactive Spreadsheet: Full-featured spreadsheet with formula support
• Python Analysis: Run Python code directly in your browser using WebAssembly
• Data Visualization: Create charts and visualizations from your data
• AI-Powered: Get intelligent suggestions and automated analysis
• Prompt Library: Access predefined prompts or save your own for quick reuse

Probly uses a modern architecture:

• Frontend: Next.js application that runs in the browser
• Python Execution: Pyodide (Python compiled to WebAssembly) runs entirely in the browser
• LLM Integration: OpenAI API calls are proxied through the server

This design means that data analysis happens locally in your browser, providing better performance and privacy.

• Node.js 18 or higher
• npm or yarn
• A modern web browser (Chrome, Firefox, Edge, or Safari)
• OpenAI API key
