From the link sent to the patient, to the summary the doctor reads
Previza slots in before the consultation as a digital anamnesis step. Below is every stage of the process in detail — from the moment the patient receives the conversation to what the doctor sees in the exam room.
The patient receives and completes the conversation before the appointment
Right after the appointment is confirmed, the patient receives a link to the Previza conversation — by SMS, WhatsApp, or email, depending on the channel the clinic already uses. No account or app to install: the link opens the conversation directly in a regular browser, on a phone, tablet, or computer.
The conversation can be completed by three types of users: the patient themselves, a family member or caregiver (a parent, an adult child, or another relative) on their behalf, or — if the patient arrives at the clinic without having completed anything at home — on a tablet in the waiting room, guided by a member of clinical staff.
The conversation takes 5–8 minutes on average and can be paused and resumed without losing any answers already given. Questions that don't apply to the patient's situation are skipped automatically, and the tone stays simple and direct, with no complicated medical terminology.
The AI structures the answers into a consistent medical history
As the patient answers, Previza organizes the information into the categories relevant to the clinic's specialty: reason for visit, symptom history, current medication, and personal and family background. The structure is the same for every patient — no matter how detailed or brief their answers were.
This consistency is the main difference from a traditional intake, where what gets asked depends on how much time is available that day. With Previza, a patient who completes the conversation on Monday morning gets exactly the same categories of questions as one who completes it on a busy Friday evening.
The field structure is configured per specialty — a cardiology practice, for example, will have fields dedicated to cardiovascular risk factors, while a pediatric practice will have fields for vaccination and developmental history.
The doctor receives the summary, well ahead of the consultation
The summary is available to the doctor well ahead of the appointment — enough time to read it in 30–40 seconds, between consultations or even before the day starts. Each section maps directly to the structure the doctor would fill in the chart anyway, which removes the need to reread or reinterpret a raw transcript.
With the summary already read, the consultation can start straight into the clinical part: examination, interpreting symptoms, and treatment decisions — not the introductory questions the patient has already answered.
The summary stays prep material. The clinical decision, diagnosis, and final notes in the medical record remain entirely the doctor's responsibility and under their control.
Adds to your current process, doesn't require a new one
Clinics don't need to change how they schedule patients or the IT system they already use. Previza connects to the existing process at three simple points.
The link to the conversation goes out by SMS, WhatsApp, or email — whatever channel the clinic already uses to confirm appointments. No new app required for the patient.
For patients who arrive without completing the conversation at home, a tablet at the front desk or in the waiting room lets them complete it — guided by clinic staff — before they go in.
The summary reaches the doctor linked to that specific appointment, with no manual searching. The clinic's medical record and scheduling system stay unchanged.
What happens to the information, from the moment the patient answers
At the start of the conversation, the patient explicitly confirms they agree to their data being used to generate the summary.
Answers are encrypted in transit, between the patient's device and Previza's infrastructure, and at rest while they're being processed.
Structuring the answers into the summary happens entirely on infrastructure hosted in the European Union.
The summary is visible only to the doctor or clinic authorized for that appointment — it isn't shared or reused for any other purpose.
Previza applies a zero-retention policy: data doesn't stay stored on Previza's servers. The summary is delivered to the clinic, and Previza keeps no access to it, doesn't share it, and doesn't use it to train AI models. Full details are on the dedicated data security page.

Usually the clinic's front desk, right after the appointment is confirmed, through whatever channel is already in use (SMS, WhatsApp, email). The process can be automated if the scheduling system allows it.
