AI Search and Enterprise Search Agents
Agents that understand questions, search the web or company systems, and return direct answers with sources instead of lists of links.
Also called Enterprise Search Agents
What is AI Search Agents?
AI search agents answer questions by searching and synthesising information. Web-focused AI search agents query the internet and summarise results with citations; enterprise search agents search across company apps and documents while respecting permissions, and can act on what they find.

How to choose AI Search Agents.
Use these criteria to build a shortlist, then test the finalists with your own data and workflows.
Essential features
Distinguish web AI search from enterprise search; test on your own questions.
Pricing models
Per-user subscriptions or usage pricing.
Integrations
Check connectors, identity and permissions.
Scalability
Consider content volume and users. Ask what changes, and what it costs, at twice your current volume.
Security and compliance
Review data indexing, residency and training policies.
Implementation
Connect high-value sources first. Plan who owns AI search agents day to day after go-live.
Support
Check enterprise support. For AI search agents, ask how quickly the vendor responds when something breaks and whether onboarding help is included.
Customisation
Look for API access. The more AI search agents must fit your own processes, the more this matters.
