How sites use Chatref to ask eligibility questions before coordinators pick up the phone.
Chatref took over the after-hours inquiry calls and the eligibility pre-screening that used to fill our coordinator's mornings. Our team now spends their time on candidates who are actually likely to qualify — screening visit slots stopped going to waste.
Potential participants used to call, hit voicemail, and never follow up. Now Chatref captures their interest at midnight and delivers a pre-screened lead to the team by morning.
It answers participant FAQs from our own protocol docs, in plain language. Most candidates get everything they need to decide before they ever speak to a coordinator.

What happens when a candidate doesn't pass the pre-screening?
