# Releasing REX-2: AI Decision Intelligence

**Try it Free:** [rex.tigzig.com](https://rex.tigzig.com) (Mobile/Web). Open Source.

## Functionalities

- **Natural Language (NL)-to-SQL**: Query, Append, Join, Merge, Summarize, Transform
- **Complex Analysis**: Cards Segment Profiling example
- **NL-to-Python**: Statistical Analysis & Python Charts
- **Interactive Tables**: Sort, Filter, Stats (Central Tendency, Dispersion)
- **Data Structure Reports & Quick AI Analysis**
- **PDF Generation**: Formatted Reports
- **Connect to ANY DW** (MySQL/PostgreSQL)
- **Create Temporary DBs** on the fly for rapid analysis
- **Data Sources**: DB tables or Upload CSV/TXT (comma/pipe-delimited)
- **Authentication**: Auth0

## Try it for Free

[rex.tigzig.com](https://rex.tigzig.com) - No API key needed. CSV/TXT files available. Link in 'Help' section on site. Currently optimized for web/desktop only.

## Source Codes

4 GitHub repos plus schemas. Links in the 'Build' section on the website + detailed video guide.

## Video Guide

- Using REX-2 Features: ~30 mins
- Complex Queries: ~30 min
- Build Guide: ~90 min
- See comments for timestamped TOC

## Caveats

- Prototype (working version)
- Single LLM agent: stumbles occasionally. Full team on the way

## Planned Features

- **LLM / Agent Network**: Maker/Checker/Work Segregation
- **SQL-Python Log Streaming** in UI, File downloads
- **Custom Python Code Interpreter (PCI)**
- **NL-to-Python** - large datasets (needs PCI)
- **Advanced Statistical Analysis** (needs PCI)
- **Generic Excel to CSV Converters**, Universal Web Scrapers
- **Real-Time Voice** (OpenAI Alt)
- **Security / Frontend-Backend Segregation**
- **ML Models** (need PCI+)
- **On-the-fly Interactive Dashboards** (Claude-like)

## Tip: Setup Your Own Warehouse, Instantly

Neon, Aiven, Supabase offer free tiers for production-ready databases. Set up in under a minute with just a few clicks.

## Tip: Voice-to-SQL

Voice-typed using Windows Voice (Win+H). Google Docs Voice Typing is also great. Longest prompt (~5 mins of voice instructions) converted into SQL (check out at YouTube timestamp 00:49:20).

## Build Details

- **Built with Cursor AI**: My #1 AI-coding tool; recommend Volo's channel on YouTube. Links in 'Build' section
- **AI Backend**: FlowiseAI (API-connected). My top LLM App platform
- **Python Charts/Stats**: E2B on Flowise
- **UI**: React, TypeScript, Vite, Shadcn
- **DB Connections**: Custom built FastAPI servers
- **Deployment**: Vercel (main site), Hetzner (via Coolify for FastAPI), Render (Flowise)
- **User-Created DBs**: Neon (blazing fast, great APIs, ideal for LLM apps)

REX is an independent, open-source project I've developed as part of my desire to make Generative AI tools practical and accessible. It's also my way of sharing with the broader community, inspired by open-source platforms like Flowise that have benefited me immensely. Updates will roll out as I balance this with other projects.
