THE PROBLEM
Here's What This
Feature Solves
Save hours of manual reading and drafting. Calendax helps your team move from protocol to ready-to-use questionnaire in minutes, not days.
01
Protocols are Long and Dense
Study protocols can run dozens of pages, and CRCs have to read every section by hand to find the inclusion and exclusion criteria buried inside.
02
One Missed Requirement Risks Everything
A single missed or misread eligibility requirement means the questionnaire no longer reflects the actual study criteria, and inaccurate screening decisions can follow.
03
Amendments Mean Starting All Over
Every protocol amendment means manually comparing the changes and updating the questionnaire by hand, or risking a screening call built on outdated requirements.
THE SOLUTION
See the Difference
Calendax Actually Makes
All three bottlenecks share the same root cause: manual work standing between a protocol and a usable questionnaire. Here’s what happens once that’s gone.
Instant Protocol Reading
Calendax reads the entire protocol the moment you upload it, pulling out every inclusion and exclusion criterion without anyone having to read a single page.
Protocol-Matched Every Time
Every generated question comes directly from your protocol’s actual criteria, and CRCs still review and approve each one before it’s used for screening.
Regenerate in Seconds
When a protocol gets amended, regenerate the questionnaire in seconds instead of manually comparing changes and rewriting questions from an outdated version.

Let’s Get Started
BETTER TOGETHER
These Features Work Even Better Together
Automated Call Intelligence
Once your questionnaire is approved, the AI screening agent uses those exact questions to run every call, without any extra setup.
Live Calling
That approved questionnaire stays visible on screen during live calling, guiding coordinators through every question when they call a patient directly.
Match Point
DeepMatch AI uses the same protocol criteria to scan your existing database, surfacing candidates who might already qualify for this study.

Can I edit the questions Calendax generates?
Yes. CRCs can edit, add, remove, or reorder every question before approving the questionnaire, so the final version matches your exact study requirements.
What happens if my protocol gets amended later?
You can regenerate the questionnaire from the updated protocol in seconds, instead of manually comparing changes and rewriting questions by hand.
How long does it take to generate a questionnaire?
Calendax reads the protocol and drafts the full questionnaire within minutes of upload, ready for your team to review and approve.
Does the AI understand complex eligibility criteria?
Yes. Calendax identifies both inclusion and exclusion criteria directly from the protocol, including detailed or multi-part requirements, and turns them into structured questions.
Who has to approve the questionnaire before it's used?
A CRC reviews and approves every generated questionnaire before it’s used by the AI screening agent or during live calling.
Can I upload any type of study protocol?
Yes. Calendax accepts your uploaded protocol document and analyzes it directly, regardless of the therapeutic area, to extract the relevant screening criteria.
