KeRn AI Copilot

KeRn AI Copilot – Intelligent AI Assistant & Shopping Copilot for Bagisto

The KeRn AI Copilot is a state-of-the-art, vendor-neutral conversational AI assistant designed natively for Bagisto. It empowers your ecommerce store with autonomous sales guidance, instant customer support, smart catalog discovery, and vector-powered knowledge search.

Unlike simple third-party chat widgets or generic bots that only regurgitate static FAQs, KeRn AI Copilot connects directly to Bagisto’s database, cart system, customer accounts, and official B2B Suite via secure, real-time function calling and Retrieval-Augmented Generation (RAG).

Key Features

Storefront AI Sales Assistant & Chatbot

Transform passive storefront visitors into buyers with an interactive shopping advisor:

• Natural Language Shopping: Understands customer intent, advises on product specifications, and answers pre-sales questions in real time.
• Rich Product Cards: Renders clean, visual product cards directly in the chat with title, thumbnail, price, availability, and instant navigation links.
• Cart & Availability Actions: Allows shoppers to check current stock and initiate add-to-cart actions directly from conversational prompts.
• Customer Self-Service: Authenticated customers can view recent orders, inspect order items, check shipping/delivery status, and initiate one-click reorders.
• Photo Attachment Support: Customers can upload images to ask questions about specific parts, labels, or matching items.
• Real-Time Streaming: Smooth Server-Sent Events (SSE) token streaming provides an instant, responsive chat experience.
• Custom Appearance: Fully customizable floating widget with brand colors, customizable avatar, greeting messages, suggested starter chips, and positioning (left or right).
• 
  

Semantic Knowledge Base & RAG Vector Search

Turn your store data and documentation into an authoritative AI knowledge engine:

• Hybrid & Vector Search: Combines keyword search with dense vector embeddings for semantic question answering.
• Flexible Vector Storage: Built-in support for MySQL Native Vector Search (no external database required), Milvus, and Weaviate.
• Diverse Knowledge Sources: Index product catalogs, CMS pages, FAQ free text, raw PDF/Word documents, individual web pages, XML sitemaps, and full website crawls.
• Automated Chunking & Synchronization: Automatically splits long documents into optimized paragraphs and re-indexes on a configurable schedule.
• Role-Based Knowledge Access: Control whether confidential documentation is visible to Guests, Logged-in Customers, or Technicians.
• 
  

B2B Suite Integration & Quoting

Full out-of-the-box compatibility with the official Webkul Bagisto B2B Suite:

• Request a Quote: Customers can assemble multi-item B2B quote requests directly within the chat conversation.
• My Quotes Tool: B2B buyers can check open quotations, expiration dates, negotiated totals, and statuses.
• Strict Tenant Isolation: Cross-tenant quote guards ensure company buyers only access quotes belonging to their assigned company or customer account.
• 
  

Zero-Code Tool Extensibility (Plugin Discovery)

Need custom capabilities? KeRn AI Copilot features a modular plugin discovery engine:

• Automatic Discovery: Automatically scans loaded Bagisto packages for tools in src/ShopAgent/Tools/*.php or app/ShopAgent/Tools/*.php.
• Container Tag Registration: Register custom tool classes via standard Laravel container tags (app()->tag([...], 'shop-agent.tools')).
• Safe Sandboxing: Newly discovered extension tools default to disabled until explicitly reviewed and enabled by the store administrator.
• 
  

Multi-Provider & Vendor Neutrality

Never be locked into a single AI vendor. Switch or combine industry-leading LLMs at will:

• OpenAI: GPT-4o, GPT-4o-mini, o1, o3-mini
• Anthropic: Claude 3.5 Sonnet, Claude 3.5 Haiku
• Google: Gemini 1.5 Pro, Gemini 2.0 Flash
• DeepSeek: DeepSeek-V3, DeepSeek-R1
• Groq: Ultra-low latency Llama-3 inference
• Ollama: Self-hosted, 100% private local open-source models
• Azure OpenAI & Custom Compatible Endpoints: Full support for private enterprise endpoints and OpenAI-compatible gateways.
• Automatic Failover: Configurable fallback providers ensure your chat stays online even during upstream API outages.
• 
  

Enterprise Cost Control & Budget Guard

Keep AI operational costs predictable and transparent:

• Hard Budget Caps: Set monthly and daily USD budget limits with automatic, graceful degradation when limits are reached.
• Detailed Token Tracking: Monitor prompt tokens, completion tokens, cached input tokens, and cache writes for every turn.
• Model Pricing Table: Configurable pricing per million tokens ensures exact cost tracking down to four decimal places.
• Interactive Playground: Test agents, evaluate prompt changes, simulate customer permission levels, and inspect tool executions without polluting customer logs.
• 
  

Security, Privacy & GDPR Ready

Built from the ground up to respect enterprise privacy and European data protection standards:

• Built-In Consent Mode: Configurable opt-in privacy consent banner with customizable merchant policy text before initiating AI provider requests.
• Data Sanitization & Secret Masking: Automatically strips API keys, Authorization headers, and sensitive credentials from logs and error messages.
• ReDoS Protection: Safe regex engine ensures user input never causes regular expression denial-of-service hanging.
• Multi-Channel & Embed Support: Host the assistant on your Bagisto storefront, external authorized web domains via secure HMAC identity tokens, or headless mobile apps via scoped REST API tokens.
