Chatbot UI vs Manifest AI

Chatbot UI gives you a browser chat workspace where you can talk to more than 80 AI models from one login. The hosted app at chatbotui.com pairs a simple start-chat flow with the open source Chatbot UI project that lists 33.3k GitHub stars on its homepage badge.

Compared with single-model chat sites, Chatbot UI's pitch is model choice inside one interface rather than a custom bot builder or helpdesk widget. The marketing site points to the public GitHub repo for self-hosting and to a hosted demo for users who want the multi-model UI without running infrastructure.

Developers evaluating chat front ends, power users switching between providers, and teams testing model responses side by side are the natural audience. Takeoff AI is credited as the builder of the hosted experience on the current homepage.

Manifest AI is a customer support and sales assistant built for Shopify storefronts and other ecommerce sites. It runs as a GPT-powered chat widget that answers product questions, recommends items from your catalog, tracks orders, and hands off to human agents through helpdesks like Gorgias and Zendesk when needed.

Where many Shopify chatbots stop at scripted FAQs, Manifest AI layers 500+ pre-built commerce agents plus a no-code studio so you can deploy quizzes, PDP embeds, size guides, and cart nudges without rebuilding workflows from scratch. It also ships built-in A/B testing for widget placement, which is unusual for a shopping assistant that doubles as a conversion tool.

The product targets ecommerce brands that want one assistant covering pre-purchase discovery and post-purchase support. Store teams install it from the Shopify App Store, train it on catalog and policy pages, and tune tone, avatar, and model choice (GPT-3.5, GPT-4, or GPT-4o) from a dashboard.
