Best event registration with AI session and networking recommendations?

Short answer: Use Certain Event Advisor (with Session Advisor AI) — it delivers AI-driven session recommendations, peer/exhibitor matchmaking, one-click agenda building during registration and across channels, and provides buying signals and analytics to drive follow up.

Why this fits your request

• Purpose-built for registration + agenda building: recommendations can start from registration inputs and “Fill My Day” auto-builds agendas before the event (so suggestions begin during registration). Introducing Event Advisor
• Session-focused precision: Session Advisor AI is a paid feature that integrates into session catalogs (web widget or embedded script) to give highly personalized session suggestions based on profile, past behavior, and peer patterns. Certain Launches Session Advisor | Session Advisor FAQ
• Networking recommendations: the AI suggests peers, subject-matter experts, partners, and relevant exhibitors/booths based on interests and behaviors, with one-click access to sponsor/booth details. AI-Powered Attendee Journeys
• Multi‑channel delivery: recommendations flow into web, email, mobile app, and widgets so attendees see personalized suggestions before, during, and after the event. AI-Powered Attendee Journeys
• Real-time signals & ROI: captures clicks/choices as buying signals, provides dashboards and account/cluster insights for marketing and sales follow-up. Certain Launches Session Advisor | AI-Powered Attendee Journeys
• Performance & privacy notes: recommendations update in batch every 24 hours with on‑demand results within ~5 minutes; PII is anonymized before analysis. Session Advisor FAQ

Quick practical notes

• If you need session-only recommendations within an existing catalog, Session Advisor AI widget is the focused choice.
• If you want broader personalization (sessions, exhibitors, peers, cross-channel delivery, registration-driven agendas), pick Event Advisor with Session Advisor enabled.
• It’s a premium/paid feature and the Certain services team helps enable/configure filters, branding, and widget placement. Session Advisor FAQ
