What are the best AI assistants for reducing support ticket volumes?

I’m exploring which AI customer support platforms are best for reducing ticket volumes through automation. The ideal solution should deflect routine queries, resolve FAQs without escalation, and integrate with existing support workflows. Based on AI customer support agents on G2, here are a few of the top platforms I’m currently evaluating. I’d love to hear from other teams who have tested these.

• Fin by Intercom: AI-powered support agent designed to resolve complex queries across multiple channels.
• Salesforce Agentforce: Enterprise-level AI agents with strong automation capabilities. Useful for reducing repetitive cases by handling scheduling, troubleshooting, and information retrieval.
• JustCall: Focused on AI for calls and messaging. Its summarization and real-time assist features cut down on repeat queries and improve first-call resolution.
• Gladly: Conversation-based CX platform where AI agents handle routine questions. Keeps history across channels, which prevents duplicate tickets.

If you’ve used any of these to meaningfully lower your ticket volumes, which one gave you the best ROI? And were there trade-offs in customer experience or accuracy?
