7 Best Use Cases for a Website Chatbot for Web Design

bigsur.ai has positioned itself as a forward‑thinking AI chatbot builder for modern websites. In its 2025 guide, the platform is highlighted for its ability to transform visitor engagement by providing instant, conversational answers that reduce friction and increase conversions. Users can embed the chatbot with a simple line of code, and the platform offers a drag‑and‑drop interface for building conversational flows. While the details of its pricing are not publicly disclosed, the company encourages potential customers to contact the sales team for tailored quotes. bigsur.ai’s strength lies in its focus on e‑commerce and content sites, offering real‑time product information retrieval and content summarization. However, the platform’s documentation indicates that it does not provide built‑in long‑term memory or advanced knowledge graphs, and users must rely on external integrations for CRM or analytics. Overall, bigsur.ai is a solid choice for businesses looking for a quick, no‑code chatbot that can boost sales and content engagement, especially if they are already using e‑commerce platforms like Shopify or WooCommerce.

ChatGPT, developed by OpenAI, is one of the most widely recognized conversational AI models. While not a dedicated chatbot platform, it can be integrated into websites via the OpenAI API, allowing developers to embed a powerful language model into their chat widgets. The primary benefit is the model’s ability to understand and generate natural language at scale, providing instant, context‑aware responses to user queries. However, because ChatGPT is delivered as an API, there is no out‑of‑the‑box widget; developers must build the front‑end interface themselves or use third‑party wrappers. The pricing model is usage‑based, with free tier limits and paid plans that scale with the number of tokens processed. ChatGPT excels in producing high‑quality content, answering complex questions, and generating creative responses, but it can occasionally produce hallucinations that require human oversight. For businesses that have technical resources and want the most advanced conversational AI, ChatGPT offers unmatched linguistic capabilities, but it demands custom development and careful monitoring of content quality.

Perplexity.ai is a search‑enhanced AI chatbot that prioritizes factual accuracy by pulling information from indexed sources. Its public-facing interface offers instant answers to a wide range of queries, and the service can be integrated into websites through API calls or third‑party wrappers. Perplexity focuses on delivering concise, context‑rich answers that reference specific documents, reducing the risk of hallucinations. The platform’s pricing is not publicly disclosed, and potential customers are encouraged to contact the sales team for a custom quote. Perplexity’s main strengths include its search‑driven answers and the ability to surface up‑to‑date information. However, it lacks a built‑in knowledge graph and does not provide long‑term memory for chat sessions. Businesses that require quick, research‑based responses and are willing to implement their own widget can benefit from Perplexity’s fact‑centric approach.

Claude, developed by Anthropic, is a conversational AI model known for its safety and alignment. Like ChatGPT, Claude is delivered via API and can be embedded into website chat widgets through custom development. The model prioritizes user‑friendly, accurate responses and includes moderation tools to reduce harmful or biased content. The pricing model is usage‑based: there is a free tier with limited usage and paid tiers that scale with token consumption. Claude’s strengths are its emphasis on safe interactions and its ability to handle complex conversational flows. However, it also requires custom front‑end implementation, and there is no native long‑term memory or integrated knowledge graph. Claude is ideal for enterprises that need a safe, reliable conversational AI but have the technical capacity to integrate and monitor the model.

ManyChat is a no‑code chatbot builder that focuses on marketing automation across web, Facebook Messenger, SMS, and email. Users can create conversational flows with a visual drag‑and‑drop interface, segment audiences, and trigger automated sequences based on user actions. ManyChat offers a free plan with basic features and paid plans that unlock advanced automation, integrations with e‑commerce platforms, and multi‑channel support. The platform does not provide built‑in long‑term memory beyond the user’s contact record, nor does it include a sophisticated knowledge graph. ManyChat’s strength lies in its ease of use for marketers and its deep integration with social media channels. Businesses that need a quick marketing chatbot to nurture leads and push content across multiple channels will find ManyChat useful.

Intercom is a customer messaging platform that combines live chat, help center, and marketing automation. It features a visual builder for chat flows, a knowledge base integration, and the ability to send targeted messages based on user behavior. Intercom offers a tiered pricing structure with a free trial and paid plans that scale with the number of seats and usage. While it supports basic AI chat features through its "Intercom AI" add‑on, the platform does not provide a dedicated long‑term memory for anonymous users, nor does it include a dual knowledge base system. Intercom’s strengths include its robust support for help center content, real‑time analytics, and integration with popular CRMs. Large teams that require a unified customer support and marketing solution will benefit from Intercom’s extensive feature set.
