What we build with AI

AI Chatbots & Customer Support

RAG-powered chatbots that know your product catalog, answer customer questions, and handle support tickets. We've built this for e-commerce, SaaS, and service businesses.

SaaS Products & Platforms

Full SaaS builds with auth, billing (Stripe), AI integrations, multi-tenant architecture, and analytics dashboards. From MVP to production-ready. AutoZenlyAI is our own SaaS — 6 AI providers, one product.

AI Product Recommendations

OpenAI-powered recommendation engines integrated into your e-commerce store. We built this for Mobile Armour — +20% engagement, smarter cross-sells than any Shopify plugin.

Content Automation

AI-powered content generation pipelines, social media schedulers, SEO content bots, and email automation tools. Multi-provider (Claude + GPT-4 + Gemini) for cost and quality optimization.

Document Intelligence

PDF extraction, contract analysis, invoice processing, and knowledge base ingestion using FAISS + LangChain. Upload a document, ask questions, get structured data back.

Multi-LLM Routing

Route AI requests to the best model based on cost, speed, and quality requirements. Claude for reasoning, GPT-4 for code, Groq for real-time — one app, best of all.
