# Voila - AI-Powered Language Tutoring Platform

> Voila (voila.fun) is an all-in-one platform for language tutors and learners. Tutors run their entire language teaching business — AI-powered classroom, scheduling, messaging, and billing — for a flat fee of EUR 2 per session while keeping 100% of tuition fees. Students join for free and get AI-generated lesson summaries, vocabulary tracking, and access to thousands of language tutors. Voila also integrates with XR glasses (Meta Ray-Bans, Google XR Glasses) for hands-free, real-world language practice with real-time speech analysis and grammar feedback.

## Platform Overview
Voila re-imagines the tutor economy by separating payment from the platform. Unlike Preply (18-33% commission) or iTalki (15%), Voila charges tutors a flat EUR 2 technology fee per completed session. Students pay tutors directly via IBAN, Zelle, Venmo, or PayPal. Active referrals drop the fee to EUR 1 per session.

## For Tutors
- AI Teaching Assistant: Generate lesson plans, roleplay scenarios, and custom images instantly. Multi-modal coverage for reading, writing, speaking, and listening.
- AI Lesson Summaries: Multilingual transcription that outperforms Google Meet, Otter.ai, and Fireflies. Detects code-switching and dual languages in lessons.
- Interactive Classroom: Specialized video platform with a collaborative board. Upload PDFs, annotate images, use sticky notes, and share a Google Doc-style board.
- Seamless Scheduling: Integrated with Google Calendar. Manage student roster, cancellations, and availability.
- Private Messaging: Secure in-app messaging so tutors keep personal contact info private.
- Free Tutor Directory: Students discover tutors at no cost — no lead fees.
