7 Must-Have RAG‑Powered AI Agents for Office Cleaning

Landbot.io is a visual chatbot builder that empowers businesses to create conversational experiences without coding. Its drag‑and‑drop interface lets users design flows, add media, and embed forms directly into websites or messaging platforms. Landbot’s RAG capabilities are facilitated through integrations with document storage services and its own knowledge base, enabling agents to fetch up‑to‑date answers from PDFs, spreadsheets, and web pages. The platform also offers conditional logic, real‑time analytics, and multi‑channel deployment, allowing chatbots to operate across web, WhatsApp, and Facebook Messenger. Landbot’s pricing structure includes a free tier with limited chat sessions, a Pro plan at $49/month (or $39/month when billed annually) that supports up to 500 chats per month, and a Premium plan at $99/month with unlimited chats and advanced integrations. The platform is especially well suited for small to mid‑size businesses that need a quick, visual way to prototype and launch chatbots. Strengths of Landbot include its intuitive flow builder, extensive media support, and strong integration ecosystem. However, it lacks a dedicated knowledge graph feature, and its RAG capabilities rely on external integrations rather than a built‑in retrieval engine. Landbot is ideal for customer support, lead generation, and interactive FAQs across various industries, including office services.

ManyChat is a popular chatbot platform initially focused on Facebook Messenger but has since expanded to website chat widgets, SMS, and email. It offers a visual builder that allows users to design conversational flows using drag‑and‑drop modules, integrate with e‑commerce platforms like Shopify, and trigger automated sequences based on user actions. ManyChat’s RAG functionality is primarily handled through its built‑in knowledge base, which can pull answers from FAQs and external content via webhooks. The platform’s pricing includes a free plan with basic features, a Pro plan at $10/month (or $8/month when billed annually), and a Growth plan at $25/month (or $20/month annually). ManyChat is well suited for businesses that rely heavily on Facebook lead generation, but its website widget feature is increasingly used for live chat and support. ManyChat’s strengths are its deep integration with Facebook, SMS, and email, and its robust automation workflows. However, it does not offer a dedicated knowledge graph, and its RAG capabilities are limited to simple keyword matching or webhook‑based content retrieval. ManyChat is ideal for marketing teams that need to capture leads through social media and website chat while automating follow‑up emails.
