A paid, ad-free search engine that answers to its users
Subscriptions replace advertising, so there are no sponsored results, affiliate links, or data sales influencing what you see.
Rank any website up or down, pin favorites, or block domains entirely so your results match your own standards.
Append a question mark to get an AI answer above the results, or chat with the Assistant for deeper tasks with sources included.
Restrict searches to categories like forums or news, or jump straight into a specific site's own search with shortcuts.
AI agents that answer, qualify, book and follow up across every channel
AI agents handle inbound calls and run proactive outbound campaigns across voice, SMS, email and chat, 24/7, without adding headcount.
Agents qualify, answer, transfer, schedule, escalate and route each conversation based on intent, context and your business rules.
Book appointments, schedule callbacks, execute live transfers to human reps, trigger workflows and capture documents and signatures automatically.
Conversations are dispositioned automatically, CRM records are updated, and customer data syncs back into your existing tools and workflows.
