By the numbers

Recall is measurable. So is what slips.

Independent hygiene runs on the recall book, the rhythm that keeps patients coming back on schedule. Here's what a concierge that helps you keep that rhythm can hold.

How Fern works a busy day

Four quiet steps, every time.

Not a chatbot script. A disciplined front desk. Fern only ever does these four things, and never pretends to do a fifth.

01 · Answer

Catches the calls you miss

A visitor on your site, or a caller you couldn't pick up. Fern answers by chat and texts back the missed call in plain language. No forms, no login.

02 · Sort

Sorts what's next

A new client, a recall that's due, a family asking about a home visit? Fern sorts each by the rules you set, and routes it the right way.

03 · Book

Books or brings back

Grounded in your own facts (hours, services, CDCP direct-billing, your service area), Fern captures a booking or nudges a lapsed client back, only where consent is on file. Never a guess.

04 · Hand off

Delivers it ready

Every request lands ready to confirm: a structured text or a tidy email, straight to the inbox you already watch. No new software, nothing to learn.

Meet Fern

Watch her answer. And watch her refuse.

The hard part of a concierge in a practice isn't answering. It's knowing when not to. Pick a question and watch how Fern draws the line: booking what she can, routing anything clinical to you.

Live · Not a Script

That tour was scripted. The real Fern is live.

The walkthrough above follows a set path. The real Fern runs on our engine. Ask her anything in your own words, and watch her stay grounded, refuse by name, and route a true emergency to 911 the same way, every time.

Talk to the real Fern

Sample practice, sample facts. Behaviour is the real thing. Fern is intake, booking and routing only; she is never a clinician and never diagnoses. Emergencies bypass the model entirely and fire a deterministic script.

Honest by architecture

Safe isn't a promise. It's the build.

A concierge in a practice can do real harm if it bluffs, and most “AI chat” does, then gets quietly retired after it invents an answer in front of a client. So Fern is engineered (to OWASP's LLM Top-10) so that the honest thing is the only thing she can do.

Closed to the open web

No live internet, no wandering. Fern can only reach the vetted knowledge vault your practice approves, and nothing else.

Refuse by default

If the answer isn't in her vault, she says so and routes to you. A clean “I'll check and confirm” beats a plausible guess.

Emergencies bypass the model

Airway, bleeding, trauma: deterministic tripwires fire a fixed 911/ER script. The language model is never in that loop.

Scope-locked to intake

Fern answers, books, and routes. She never diagnoses, never prescribes, never plays clinician. By construction, not by reminder.

Data minimisation

She gathers only what the hand-off needs, never writes to your chart, and holds it no longer than needed, so there's simply less to breach.

Provable & improvable

Every conversation is logged and reviewable, so you can audit exactly what Fern said, and tighten her over time.

The law, right

PHIPA and PIPEDA govern here, not HIPAA. HIPAA is US law and doesn't apply to an Ontario practice. A vendor who leads with “HIPAA-compliant” is telling you they haven't read the room. As an independent hygienist you're the health-information custodian; Fern works as your agent, data minimised, never pooled, and never fed into a public AI tool.

Your College, too: the CDHO, not the RCDSO. Fern is built to the CDHO's AI guidance: she discloses she's AI, offers a human alternative for anyone who'd rather not use it, and logs that consent. And because recall and reactivation are commercial messages under CASL, every nudge carries consent, sender identification, and a working unsubscribe, with lapsed clients held back until express consent is on file.

Proof, not promises

24 / 7

Always on

When the phone rings and your hands are full, Fern is on: webchat around the clock, and a text back to the calls you miss.

No new tools

New apps, logins, or dashboards to run. It lands in the inbox you already watch.

100%

Yours to export

Your content, approved knowledge, and conversation logs are yours to keep and export, never held hostage. The service runs Fern; the data stays yours.

Top-10

Secure by design

Engineered against OWASP's LLM Top-10 and Canadian privacy law: security in the foundation, not an afterthought.

Not the usual AI widget

The Holkin way vs. the widget trap.

Most “AI chat” for a practice keeps your clients' words on someone else's server and hands them back only while you keep paying. Fern is month-to-month too, but what she's built on stays yours: your content, your conversations, your site, exportable and never held hostage.

	The usual AI widget	Fern, by Holkin
Your data	Your clients' words sit on their cloud; stop paying and they vanish with it.	Your site, content, and approved knowledge are yours, exportable and never held hostage.
Client data	Pooled on a shared vendor cloud, terms subject to change.	Minimised and kept separate for each practice, never pooled with anyone else's.
When unsure	Guesses confidently to keep the chat going.	Refuses and hands to a human. By design.
Your desk	A new dashboard to monitor and learn.	Nothing new: requests land in the inbox you use today.
Lock-in	Multi-year contracts and auto-renew, with fees to leave.	No multi-year contract, no exit fee. Month-to-month, cancel anytime; your data and site stay yours.
The law	Often “HIPAA-compliant.” Wrong country.	PHIPA + PIPEDA + CDHO, the law that binds an Ontario hygienist.

We study your practice first

No two practices get the same Fern.

She's only as honest as the facts behind her. So before a single line ships, we build her knowledge from your practice, read back and approved by you.

01 · Recon

We read your practice

Your services, hours, service area, CDCP direct-billing, how you take bookings, mapped exactly as your clients meet them today. We arrive already knowing whether you need the concierge alone or the whole owned front door.

02 · Vault

You approve every fact

Fern's knowledge is verified line by line with you and marked verified, draft, or needs-review. Nothing goes live unread. Your advertising is your responsibility under the CDHO, and Fern stays inside it.

03 · Sign-off

You sign the protocol

Your scope, your emergency routing, your consent and unsubscribe rules get your signature before Fern ever takes real traffic. That's the gate.

And she's never finished. Fern starts as the front desk you couldn't hire; because the build is shaped around your practice, she grows on your terms: deeper booking, new intake flows, more of the recall book automated, added only when each earns its place. Never a fixed menu you're locked into.

The careful clinician's questions

Asked and answered.

Could Fern give a client clinical advice?+

No, and not because we asked it nicely. Fern is scope-locked to answering, booking, and routing. She never diagnoses, never assesses, never prescribes. Anything clinical is handed to you, and true emergencies fire a fixed 911/ER script the model can't override.

If Fern gets something wrong, who's liable, and does this keep me onside with the CDHO?+

You stay the accountable clinician and custodian. The CDHO expects that, and nothing here changes it. What changes is your exposure: Fern never diagnoses, speaks only from facts you approved, refuses when she's unsure, and logs every exchange, so she's engineered to reduce the risk of a misstep, not add one. She's built to the CDHO's AI guidance, and everything she says stays inside advertising you've approved.

Can Fern message my lapsed clients to bring them back. Is that CASL-legal?+

Yes, correctly. Recall and reactivation are commercial messages under CASL, so Fern only messages where consent is on file: she captures express, timestamped consent at intake, puts sender identification and a working unsubscribe on every message, and holds back clients outside the two-year implied-consent window until you have express consent for them. The reactivation that's legal to send, sent. The rest flagged, not fired.

Is this HIPAA-compliant?+

HIPAA is US law and doesn't apply to an Ontario practice. That's the giveaway question for a vendor who hasn't done their homework. Fern is built to PHIPA (Ontario) and PIPEDA: data minimised, never sold or pooled, never fed into a public AI tool, and auditable line by line. Your data is US-hosted on infrastructure we control, which PHIPA and PIPEDA permit for an Ontario practice with the safeguards in place. You're the custodian; Fern is your agent.

How does Fern handle a genuine emergency?+

Deterministically. The language model is never in that loop. Airway trouble, facial swelling, uncontrolled bleeding, trauma: hard-coded tripwires fire a fixed “call 911 or go to the ER now” script. Fern can't decide to handle an emergency in conversation, because the model never gets the chance.

What happens when she doesn't know something, and can I edit what she says?+

She says so. Fern is closed-book: if an answer isn't in the knowledge you approved, she doesn't improvise. She tells the client she'll have you confirm and logs it for follow-up. And that knowledge is yours to edit, line by line; nothing goes live until you've read and signed off. A clean hand-off beats a confident guess, every time.

Do I need a specific website, a PMS, or new software to run this?+

No. If you run Jane, Open Dental, or just a calendar, Fern works alongside it. She hands you a fully-formed booking and, where the tools allow, reads your free/busy; she never writes to your chart. Already have a website you like? On most platforms Fern layers right onto it, with nothing to tear out and no need to change who builds or hosts it. Run nothing but a phone and paper? Fern handles booking and recall outright. And if you have no website (or only a Facebook page), the owned site is a module we build as one system with the concierge. Hand-offs land in the inbox you already watch: no new dashboard, nothing to learn.

Can Fern actually book, and what if I need something you haven't listed?+

Today Fern hands you a fully-formed booking request (name, reason, contact, preferred times, and for a home visit the resident and facility details a family member gives on their behalf), deliberately without writing to your chart, so there's less to secure. Want deeper booking, recall automation, or a specific integration? That's the advantage of owning the build rather than renting a fixed product: we scope it to your practice and add it when it earns its place. Full voice is on the roadmap, held until it can be as honest as the rest of Fern. Never a recorded guess.

Does Fern speak French, or other languages?+

Yes. Fern answers in your client's language, with the same approved facts and the same honest refusals in each one. She works in English, French, and Spanish today: the regulated disclosures are written and approved in each language and shown word-for-word, and every answer draws from the same facts you've approved, so a French- or Spanish-speaking client gets the same grounded, refuse-by-default concierge, never a loose guess. Need another language your community speaks? Because you own the build, we add it deliberately, held to the same review.

What do my clients see, and do they know it's AI?+

A concierge that matches your practice, not a generic chatbot dropped on top. Fern introduces herself in plain language as your practice's concierge and never impersonates a person or a clinician, so clients always know what she is, and anyone who'd rather not use AI is offered a human path instead. That's exactly what the CDHO's AI guidance asks: disclose the AI, offer an alternative, log the consent. Fern does, by default.

Do I own it, or am I renting?+

The asset is yours; the service is a subscription. Fern runs month-to-month, cancel anytime, no lock-in, and what she's built on stays yours: your content, your approved knowledge, your conversation logs, and, if we build you one, your site, all portable and exportable, never held hostage. What you pay for is the service that runs her, not a perpetual licence that evaporates the day you stop.

The phone you can't answer, answered.

Your hands are full. The phone still rings.
