Voice AI for UK healthcare

Every patient called, before an appointment is missed.

HexAI’s agents confirm appointments, find out why patients can’t come, and rebook them in the same call.

Or book a demo for your pathway.

Hear a call, then try it yourself

The sample shows an appointment being rebooked and what is recorded for staff. Then talk to the agent in your browser, or have it ring your phone.

  • Introduces itself as an AI assistant
  • Records every answer for your staff to review
  • Follows up by text with a way to call back

Why we exist

England’s hospitals recorded 113.2 million outpatient attendances in 2024/25. Behind every one is a person, and many of them are waiting on a phone call. We started HexAI to help make sure that call comes.

    Our solution today

    Fewer missed appointments

    Our agents call patients ahead of their appointment, confirm they’re coming, ask why when they can’t, and rebook them in the same call. Anyone who misses the call gets a text with a way to call back.

  2. A pre-assessment nurse smiling at a completed record on her tablet

    On our roadmap

    Assessments by phone

    Pre-operative and airway assessments that a clinician writes once and the agent holds by phone, with the patient or with a parent for a child. The clinician reviews and decides.

    Further ahead

    Every specialty, every language

    One assessment engine any outpatient specialty can reuse, in more of the languages spoken in UK homes, so no patient is left out because of a form.

HexAI was founded in 2025 by an NHS anaesthetist and a cybersecurity engineer, to give clinical teams back the time routine calls take, and to reach patients that apps and web forms leave behind.

The calls that keep a pathway moving are the first to slip

Unreturned consent forms. Pre-op questionnaires chased for weeks. Reminders that never went out. HexAI has specialised agents across five care operations: one platform that follows the patient from first contact to follow-up, and records every step.

  1. Consent

    The first call any patient receives. It asks whether they’re happy to be contacted by an AI assistant and records their answer before any automated calls are scheduled.

  2. Appointments

    Pre-appointment triage, check-in and reminder calls that confirm, rebook or cancel — and follow up by text with a callback option when a patient can’t answer.

  3. Pre-operative

    The full pre-op questionnaire completed by phone, answers scored and flagged for clinicians, with follow-up and feedback calls after the visit.

  4. Airway assessment

    Specialist airway screening in conversation, with photo capture through the patient portal feeding the clinician’s review.

  5. Follow-up & clinician messages

    A clinician writes the message; the agent confirms the patient’s identity before reading it out, and never redials on its own.

Your pathway next

Agents are configuration, not code. New form-driven calls can be added to the platform without a software release.

A conversation patients stay in

The difference between a completed pre-op assessment and a hang-up is how the call feels. It’s where we spend most of our engineering effort.

From an appointment call (illustrative)
  1. AgentYour appointment is on Thursday at ten, at the—
  2. PatientSorry, can we make it the afternoon? I work mornings.Patient interrupts; the agent stops mid-sentence
  3. AgentOf course. I have 2:15 or 3:40 on Thursday. Which suits you?Offers the slots that are free
  4. PatientTwenty past three... no, 3:40 is fine.Hears the correction, keeps the final answer

  • Handles interruptions

    Patients can interrupt, hesitate or change their answer. The agent stops, listens and carries on from where the patient is.

  • Professional British voices

    A curated set of warm, professional UK voices. Choose per agent, preview before you commit, and keep one consistent voice for your service.

  • Knows who it’s talking to

    Speech recognition is primed with the patient’s, agent’s and hospital’s names, and the agent asks the patient to confirm who they are.

  • Speaks your patients’ languages

    English today. Hindi, Spanish and Bengali are built in and in testing; the agent switches to the patient’s language from their first sentence.

  • Grounded in the patient’s pathway

    Every reply draws on the patient’s appointment and pathway details, and every answer is saved, attributed and timestamped, for your staff to review.

  • Tested with simulated patients

    Response time, turn-taking and accuracy are measured with simulated patient calls as the agents are developed.

Who it’s for

    We’re designing calls a parent or carer can take part in, at a time that suits them.

  • A nurse reviewing a completed record on a tablet

    Nurses

    See the routine answers before the appointment begins.

  • A surgeon talking with an older patient on a ward

    Clinicians

    Review what the patient said, and make every clinical decision.

Governance built into the platform, not added afterwards

An AI that phones patients has to clear a higher bar than a chatbot. This is how the platform is built to meet it.

  • Data residency you choose

    Choose UK Regional or UK + EU Regional processing, or self-host inside your own estate, with calls on your own numbers. The model is set out on our deployment page.

    See deployment options

  • Patients asked first

    No automated call is scheduled until a patient’s agreement to AI calls is on record. Their answer is recorded, and they can withdraw at any time.

  • Auditable by design

    Every call transcribed and attributed. Subject-access export and right-to-erasure are built-in operations, not support tickets.

  • Humans hold the line

    Authorised staff can end any live call with one click, and test mode rings your team’s browsers, never a patient, while you evaluate.

  • Explainable risk scores

    Risk scores come with the reasoning behind them, so a clinician can inspect, challenge and overrule them.

  • Designed for UK GDPR

    Encryption in transit, role-based access, and subject-access and erasure built in. Your organisation stays the data controller, and we publish our assurance status as it progresses.

    Read the security overview

Runs where your governance says it should

Your estate, your numbers, your rules. The platform adapts to your governance, not the other way round.

Full residency and telephony details are on the deployment options page.

  • Self-hosted

    The full stack in your own infrastructure: media, models and data stay inside your estate.

  • Managed cloud

    We run the models and voices for you. Switch between managed and self-hosted models from the console at runtime, with no redeployment.

  • Your own numbers

    Bring your hospital’s Twilio or Telnyx account. Patients see the number they already know, per care pathway.

Questions we’re asked first

Does HexAI replace clinical staff?

No. The agents make the routine calls that teams struggle to get to. Anything clinical is flagged for a clinician to review, and authorised staff can end any live call with one click.

Where is patient data processed?

You choose UK Regional or UK + EU Regional processing, or self-host the full stack inside your own estate. The residency model is published on our deployment options page.

How is patient consent handled?

No automated call is scheduled until a patient’s agreement to AI calls is on record. Their answer is recorded, they can withdraw at any time, and your organisation remains the data controller.

Can calls come from our own hospital number?

Yes. Bring your organisation’s Twilio or Telnyx account and patients see the number they already know, set per care pathway.

Which languages can the agents speak?

English today. Hindi, Spanish and Bengali are built in and in testing. The agent switches to the patient’s language from their first sentence.

What happens when a patient doesn’t answer?

Appointment agents follow up by text with a callback option. Calls carrying a clinician’s message are never redialled automatically: a member of staff decides what happens next.

How can we try it without calling patients?

Test mode rings your team’s browsers instead of patients, so you can evaluate every agent end to end before going live. You can also ask our agent to call your own phone from this page.
