Website visitors don't always think in keywords. They ask questions. Especially now thanks to AI search influence.
Someone comparing services might want to know which option fits a particular situation. A student may ask about deadlines, accommodation and financial aid in the same conversation. An association member may need guidance buried across a standard, webinar and policy document.
Conversational AI search is designed for these messier journeys. Instead of returning a page of links after every query, it can interpret natural language, maintain context across follow-up questions and answer from an approved body of content.
The platforms below take different approaches to that job. Rather than running through another generic feature checklist, this roundup looks at five visitor moments that reveal what each platform is actually built to do.
AddSearch is the strongest overall choice for organizations that want conversational discovery and full website search working from the same content.
AddSearch Experience brings keyword search, AI Answers and AI Conversations together in one platform. A visitor can search for a page, ask a direct question or continue with follow-ups without starting again. Responses are grounded in the organization's own indexed content and include source citations, giving the user a route back to the original material.
The platform also gives website teams control over what enters the index, how responses sound and which content areas should be excluded. Conversation logs expose unanswered questions and content gaps, while APIs and customization options give developers room to shape the experience.
Security is documented clearly. AddSearch is SOC 2 Type II certified and GDPR-compliant, supports WCAG 2.2 and doesn't use customer content to train AI models.
This balance is why it takes the first position. AddSearch works for content-rich public websites, including universities, government bodies, financial institutions, associations and manufacturers, without narrowing the product to one sector.
Raffle combines website search, conversational answers and audience insights. Its interface can let visitors move between a familiar search experience and an AI-guided conversation, which is useful when users don't all want to interact in the same way.
The platform can index website content, interpret varied phrasing and misspellings, and provide answers through a customizable interface. Teams can adjust tone, labels, branding and interface behavior. Raffle also tracks common questions and session trends, turning conversations into a source of content and customer intelligence.
Its positioning is especially relevant for commercial and service websites that want to understand what buyers ask before making a decision. Search and conversation data can reveal missing information that ordinary page analytics won't explain.
Raffle is less established than the large enterprise-search vendors, so buyers should examine its integrations, content-governance controls and support model against their exact requirements. But for teams wanting search and conversational assistance in one approachable layer, it's a credible name that often gets overlooked.
Betty is purpose-built for professional associations and societies. That narrow focus is its advantage.
Associations often hold valuable knowledge across standards, certification materials, research papers, event recordings, slide decks and member-only resources. Betty turns that library into conversational guidance for members, staff and volunteers. Responses are grounded in the association's vetted content and cite the source material.
The platform can provide different experiences for members and public visitors, helping organizations protect proprietary resources while keeping them searchable for authorized audiences. It also supports multiple languages and provides insight into recurring member interests and content gaps.
Betty makes far less sense for a general company website. Its workflows, terminology and service model are designed around membership organizations. For that audience, however, specialization can be more useful than a broader platform that needs extensive configuration before it understands association content.
Halda focuses on higher education and student enrollment. Its AI search uses institutional website content to answer questions about programs, applications, scholarships, campus life and other parts of the student journey.
The interesting part isn't simply producing an answer. Halda connects the conversation to enrollment actions and can identify questions the institution's existing content can't answer. Admissions and marketing teams can use those gaps to improve the website, clarify guidance and reduce uncertainty at important decision points.
That makes Halda well suited to colleges and universities that see conversational search as part of a wider recruitment journey. A prospective student can move from asking a question to understanding the next relevant action rather than being left with another set of pages to interpret.
The same specialization is also the limitation. Organizations outside education won't benefit from the enrollment workflows and sector knowledge that distinguish the platform.
SiteGPT is designed for businesses that want to train a conversational website assistant on their own pages, files and connected content sources without a long implementation.
Teams can scan a website, upload documents or connect sources such as Notion, Google Drive, GitHub and YouTube. The resulting experience can answer visitor questions in multiple languages, collect lead details and hand a conversation to a human when the request needs personal support.
SiteGPT also includes conversation history, feedback, analytics and content syncing. Integrations with support and messaging platforms make it useful for companies that want website questions to flow into an existing service workflow.
It's a more support-led product than a complete site-search platform. Organizations that need faceted results, extensive ranking management or formal public-sector governance may find it too narrow. For smaller businesses prioritizing quick setup, support deflection and human escalation, that narrower scope may be exactly the point.
A polished demonstration can make every platform look capable.
Use your own content and ask questions that expose how the system behaves when the answer isn't obvious:
AddSearch is the best overall option for organizations that want conversational answers, source citations and complete site search in one managed platform. It has the broadest fit across different types of content-rich websites.
The smaller alternatives become more compelling when the use case is specific.
Raffle suits teams combining search, guided conversations and visitor insights. Betty is the specialist choice for association knowledge. Halda is built around higher-education enrollment, while SiteGPT gives smaller companies a quicker route to automated website support.
The right choice depends on what should happen after the first answer. Good conversational search doesn't just respond naturally. It keeps the visitor oriented, shows where information came from and helps them take the next useful step.
