Yes, two. CTCAE by Burna AI is the app clinicians and research coordinators use while they work adverse events during a trial: capture a visit by voice or text, review the suggested CTCAE grade and attribution with the evidence behind it, and sign off or change each one. A site issues it to its own staff, so there is no self-service sign-up. Healthnotes is the app for trial participants, deployed by a sponsor through its sites: the participant opens an enrollment link from their study site, and that link is the sign-in. The full platform runs in the browser at app.burna.ai. Care Journal is a separate free consumer app, provided by the Counted Voice Foundation and built and operated by Burna AI, at carejournal.ai.
