Multilingual AI Annotation Platform for Low-Resource Languages
# LinguaLabel
**The Multilingual AI Annotation Platform for Low-Resource Languages**
LinguaLabel is a cutting-edge annotation platform and marketplace connecting AI companies with native speakers of underserved languages. We serve the 3 billion people whose languages lack adequate NLP tools.
## The Problem
- Only ~20 of 7,000+ world languages have adequate NLP tools
- AI companies spend $1B+ annually on annotation but can't access rare language speakers
- Scale AI, Mercor, and Surge AI focus on English-first markets
## Our Solution
- **Purpose-built annotation tools** for multilingual NLP (RTL support, complex scripts, audio)
- **Native speaker marketplace** with diaspora and in-country recruitment
- **Quality-first approach** with multi-annotator consensus and expert review
## Target Languages (Phase 1)
| Region | Languages |
|--------|-----------|
| Indian | Hindi, Bengali |
| African | Swahili, Yoruba |
| Arabic | Egyptian Arabic, Gulf Arabic |
## Tech Stack
- **Frontend**: Next.js 15 (TypeScript, Tailwind CSS)
- **Backend**: Python 3.10+ (FastAPI, SQLAlchemy)
- **Database**: PostgreSQL
- **Annotation**: Label Studio SDK integration
- **Payments**: Stripe Connect for annotator payouts
- **Infrastructure**: Vercel (frontend) + Railway (backend)
