I need a complete end-to-end AI SaaS platform (web + mobile) similar to Manus AI, but more powerful. The system must support Arabic, Hebrew, and English, and include fast UI, secure login, and full payment integration. Core features required: • AI Website Builder that generates clean HTML/CSS/JS and allows full customization. • AI Video Maker that creates product videos, promos, ads, testimonials, with AI voice-over + auto captions. • AI Image Generator for high-quality, commercially safe images. • AI Ads Generator for Facebook, TikTok, Instagram (copy + designs). • User Dashboard with login/registration, credits, history, and subscriptions. • Payments: PayPal + Stripe (one-time + recurring). Technical requirements: • Single codebase where possible (React/Next.js preferred). • Multilingual interface (AR/HE/EN). • 3–5 sec avg generation speed. • Clean backend (Node/Python) with documented APIs. • Deployment-ready: Docker, staging + production setup. Tell me your timeline, milestones, and best total price for full delivery.
