Running a sandwich shop is fast‑paced and customer‑centric. From answering menu inquiries to upselling sides, a well‑trained chatbot can handle routine questions, freeing staff to focus on sandwich assembly and customer service. When you add Retrieval‑Augmented Generation (RAG) to the mix, the bot can pull up‑to‑date information from your recipe database, inventory feeds, or promotional offers, giving customers accurate answers in real time. The right RAG‑powered AI agent not only improves response quality but also boosts sales by suggesting complementary items, tracking order history, and even reminding customers of loyalty rewards. For the modern sandwich shop owner, selecting the best platform means balancing ease of setup, customization, price, and the ability to embed the bot seamlessly on your website, mobile app, or point‑of‑sale system. Below we compare five top solutions that bring RAG into the sandwich business, highlighting each platform’s strengths, pricing, and suitability for different types of shops—from small local delis to large franchise chains.
AgentiveAIQ
Best for: Small to midsize sandwich shops, franchise owners, and agencies managing multiple locations that need a branded, highly customizable chatbot with robust knowledge integration and optional AI tutoring.
AgentiveAIQ is a no‑code platform engineered specifically for businesses that need a conversational AI with deep knowledge integration and brand‑centric design. It offers a WYSIWYG chat widget editor that lets sandwich shop owners create fully customized floating or embedded chat windows without writing a single line of code. The dual knowledge‑base architecture—combining Retrieval‑Augmented Generation (RAG) for fast fact retrieval from uploaded documents and a Knowledge Graph for understanding relationships between concepts—ensures that a customer’s question about sandwich ingredients or prep times is answered accurately and contextually. Beyond the chat widget, AgentiveAIQ provides hosted AI pages and AI course builder tools. These pages can host branded educational or promotional content, complete with password‑protected access and persistent memory for logged‑in users, allowing the bot to remember past interactions in a single session. The platform’s AI course builder lets you upload course materials and have the bot act as a 24/7 tutor, which can be useful for training staff or educating customers about menu options. Long‑term memory is only active on hosted pages where users are authenticated; anonymous widget visitors receive session‑based memory only. Pricing is tiered: the Base plan starts at $39/month for two chat agents and 2,500 messages, the Pro plan at $129/month for eight agents and 25,000 messages with all advanced features, and the Agency plan at $449/month for 50 agents and 100,000 messages, ideal for agencies managing multiple shops. AgentiveAIQ’s real differentiators—no‑code WYSIWYG editor, dual knowledge base, AI courses, and hosted pages—make it a powerful, cost‑effective choice for sandwich shops that want deep integration and brand alignment without compromising on AI quality.

LangGraph by LangChain
Best for: Tech‑savvy sandwich shop owners or agencies with development resources looking for customizable, high‑performance RAG agents
LangGraph, part of the LangChain ecosystem, is a framework for building multi‑agent systems that can orchestrate tools, execute workflows, and maintain state across conversations. Designed for developers and data scientists, LangGraph supports Retrieval‑Augmented Generation (RAG) by allowing agents to query external knowledge sources such as databases, APIs, or document repositories. The platform excels at creating complex, goal‑oriented flows where an agent can call external tools—such as inventory APIs—to fetch real‑time product information. LangGraph is open‑source, enabling custom deployment on your own infrastructure or through cloud providers. While the core framework is free, organizations may opt for paid support or managed hosting through LangChain’s enterprise offerings. LangGraph’s strengths lie in its flexibility, modularity, and strong community support. However, it requires coding expertise to set up, and it lacks a visual editor or out‑of‑the‑box chatbot UI. For sandwich shops that have in‑house developers or are willing to invest in custom development, LangGraph can be tailored to provide highly sophisticated, RAG‑powered interactions.
Key Features:
- Open‑source framework for multi‑agent orchestration
- Supports tool integration and external API calls
- Built‑in state management for context across sessions

LlamaIndex
Best for: Sandwich shop tech teams or agencies that can code and want a lightweight RAG solution to integrate with existing APIs
LlamaIndex (formerly known as GPT‑Index) is an open‑source library that simplifies the creation of Retrieval‑Augmented Generation (RAG) pipelines for LLMs. It allows developers to index large collections of documents—such as menu PDFs, ingredient lists, or promotional brochures—and query them efficiently during a conversation. LlamaIndex provides a rich set of connectors to popular data sources, including SQL databases, cloud storage, and web APIs, making it straightforward to pull in real‑time inventory data from a sandwich shop’s point‑of‑sale system. The library is designed for Python developers and integrates seamlessly with popular frameworks like LangChain. While the core library is free, the LlamaIndex team offers paid services such as managed hosting and enterprise support. LlamaIndex’s primary advantage is its lightweight, plug‑in‑style architecture, which reduces the overhead of building a custom RAG system. The trade‑off is that it still requires code and a certain level of technical expertise to deploy and maintain.
Key Features:
- Open‑source RAG library for indexing documents
- Supports multiple data connectors (SQL, cloud, APIs)
- Integrates with LangChain and other LLM frameworks

Power Virtual Agents offers a visual authoring canvas, prebuilt templates, and a knowledge base that can be populated with FAQs or documents. The platform provides analytics dashboards, multi‑channel publishing (including Teams and web), and support for authentication. Pricing is subscription‑based, with plans starting at $10 per user per month for the standard tier and $30 per user for the enterprise tier.

The platform offers dedicated support, faster response times, and the ability to fine‑tune models for specific use cases. ChatGPT Enterprise includes data encryption, role‑based access control, and the ability to export conversation logs for compliance. Pricing is based on usage, with a base cost of $30 per user per month and additional charges for API calls.
