Evening browsers are your best candidates — don't let them leave.
Most clinical trial browsing happens in the evenings, when coordinators aren't available. Chatref captures that interest, answers the first wave of questions, and queues pre-screened leads for a morning follow-up — so you never lose an evening inquiry.

How sites use Chatref to capture the participant inquiries that used to vanish overnight.
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.

One widget handles Spanish and English inquiries across three concurrent studies. We stopped losing community-based candidates to language barriers.
Does Chatref actually work outside business hours?
Yes. It runs continuously with no human involvement needed. Any visitor at any hour receives the same quality of response as they would during office hours.
How does the coordinator know an after-hours lead came in?
Via the shared inbox — every lead captured after hours is queued and visible when the coordinator logs in the next morning, with the full conversation attached.
Can a candidate start the process at night and complete it the next day?
Yes. Chatref captures where the conversation paused and the coordinator can follow up to complete the pre-screening if the candidate didn't finish.
What if a candidate asks an urgent question after hours?
Chatref captures the question and flags the conversation for priority coordinator follow-up. It does not handle clinical or urgent situations and always directs those to appropriate channels.
How quickly can after-hours coverage go live?
Minutes. Add your study content, drop in the widget snippet, and after-hours coverage begins immediately.
