Overview
The platform is a fully-featured SaaS AI agent platform for modern websites: businesses train a customer-facing AI agent on their own content and deploy it everywhere their customers are (website widget, WhatsApp, Instagram, Messenger, email and SMS) with live-chat handoff to human agents when needed. Powered by OpenAI GPT-4 and Gemini, GDPR compliant and encrypted end-to-end. We built the entire multi-tenant platform from scratch and operate it in ongoing partnership.

What We Built
- AI agent engine: OpenAI GPT-4 and Gemini powered responses that understand context and hold natural conversations, with per-tenant training pipelines
- AI training suite: PDF training (train the agent from documents and policies), URL scraping (convert web pages into usable knowledge), and a structured knowledge base per agent
- Website widget: one-line JavaScript embed, ~5-minute setup, fully customizable (colors, messages, styles, position), works on WordPress, Shopify, Wix and any site; 100+ languages supported
- Live chat & inbox: human agents step into AI conversations in real time; unified inbox with chat history, search, customer info and resolution statuses
- Ticketing system: manage, track and resolve customer requests in one place
- Analytics & reports: full chat history analysis, performance metrics and CSAT tracking
- Messaging channels: WhatsApp Business Cloud API via Embedded Signup, Instagram DMs, Facebook Messenger (full Meta App Review across 13+ permissions), plus email (SendGrid Inbound Parse) and SMS (Twilio), all end-to-end
- Billing & monetization: Stripe subscriptions with plan-gated features and seat limits enforced at API level; AppSumo OAuth integration with HMAC-verified webhooks; BYOK (customers use their own OpenAI key, AES-256-GCM encrypted)
- Security & compliance: GDPR-compliant data handling, encryption at rest and in transit
- Infrastructure: hardened VPS deployment (PM2 under systemd, survives reboots and disconnects), plus the public site and landing redesign
