No second phone. Ever.
Customers ring the number they always have — on your van, your invoices, in their phone. Tirza picks up when you can't. No new SIM, no new carrier, nothing in your pocket changes.
What Tirza does for you
In plain English.
No tech talk.
Tirza answers when you can't. If she's not sure, she takes a message. You stay in control. Below: every part of the product, in normal language, so you know exactly what you're signing up for.
The thing that makes Tirza different
Keep your own number
One short code — same as turning on voicemail
Dial **61# once and Tirza answers when you miss the call. Or **21# and she answers everything. Turn it back off any time with ##002#. Works on EE, O2, Vodafone, Three, Eir — same code on every UK and Irish network.
You set this up yourself
From your phone, in under five minutes. No developer, no consultant, no appointment. The setup is the same dial codes you already know — just a different number to forward to.
What Tirza does every day
Picking up and booking
Answers 24 hours a day
Evenings, weekends, bank holidays. Tirza starts every call with your business name.
Books straight into your calendar
Got Google Calendar? Tirza only ever offers a time the calendar shows as free, then drops the booking in. She won't double-book your own diary.
Works even without a calendar link
No Google Calendar? Tirza notes who called and why, then sends you a message. You book it in yourself.
Smart callback note when unsure
Something Tirza doesn't quite understand? She doesn't guess — she takes a note with a priority tag: urgent · price · other service · other. You get a text right away for urgent cases.
No more 'what time was it again?' calls
Confirming clients
Client gets a text and email after booking
Date, time, service, your business name — both sent. No client forgets an appointment anymore.
Self-cancel with one tap
Every message has a cancel link. Client taps, the slot opens back up. You get a notification.
You get a text after every call
Who called, what they wanted, what Tirza arranged. One message on your phone. Done.
Built for owners who don't open dashboards
Run the whole thing from your phone
Reply OK · WRONG · PAUSE · LIVE to any text
After every call you get a short summary by SMS. Reply OK if it was right. Reply WRONG and we look at the call within a working day. PAUSE stops Tirza right now; LIVE switches her back on. Tap something by mistake? Nothing harmful happens — PAUSE you can undo in one text. No app, no login.
One summary text at 6pm every day
"Today: 4 calls, 2 appointments, 1 callback. Reply LIVE/PAUSE." That's it. You always know what happened today, even if you never logged in.
Add a partner — both phones get updates
Working with someone who handles your admin? Add their number once during setup. Both phones get the same call summaries and daily total. Optional, only one extra field.
Trained the way a good receptionist would be
CalmHow Tirza talks to your callers
One question at a time
Tirza never fires three questions at someone in a row. She asks, listens, answers. Just like you'd want.
Never pretends to be human
She'll never say "I'm sorry, as an AI…" or play-act being a person. She's clear about what she is — that's why callers trust her.
Wraps up gracefully within 5 minutes
No endless calls. If something gets complicated, Tirza takes a callback note politely and you call back. Never argued, never upsold.
Anyone can ask for you and get you
Words like 'human', 'person', 'someone else', 'manager', 'owner', 'call me back' — Tirza stops and turns it into a callback request. No client is ever stuck on the line.
What we built so you never get a nasty surprise
CalmWe catch problems before you do
If a call doesn't go right, you know within 10 minutes
Caller hung up confused, line dropped, anything unusual? You get a text: caller's number saved, we're already looking at it. You ring them back, problem fixed. No silent gaps.
Voice quality — we keep it sounding right
We watch every call for early hang-ups. If callers start dropping off in the first 10 seconds, we switch to a backup voice automatically and email you so you know. You never lose calls quietly.
Google Calendar — checked every day
Google sometimes signs you out. We check daily; if your link breaks, you get a one-tap re-connect email and Tirza takes callback notes until it's back. Never a missed appointment from a logged-out calendar.
Test call required before going live
You have to call Tirza yourself once before she goes live. Prevents the "oops, call forwarding wasn't set up right" moment.
When in doubt, callback note — never a wrong booking
Two failed attempts to understand? Tirza stops trying and takes a callback note. Better a friendly 'I'll have someone ring you back' than a wrong appointment in your calendar.
Five guardrails on costs and quality
CalmSafe — no surprise bills, no abuse
Spam list: robocalls blocked
International spam and known robot numbers are blocked before Tirza picks up.
Country whitelist
Only callers from your countries get through (UK + Ireland in Phase 1; we add markets as we open them). Spam from outside your zone never reaches Tirza, never costs you a penny.
Max 5 minutes per call · max 3 calls/day per caller
No endless calls. Same caller can't call back-to-back to run up your bill — limit is 3 in 24 hours.
Hard cap £15 / €15 a month — callers never hear silence
Tirza warns you at 80% of your plan, again at 100%. At the cap, Tirza takes callback requests instead — your callers still hear 'we'll ring you back', never silence. Need extras? Buy a 5-pack (£4.45 / €4.45) or 10-pack (£8.90 / €8.90) of extra appointments any time.
Built in Europe — core data in EU
Your business profile, calendar bookings, transcripts and the audit log live in Frankfurt (EU). Live voice + AI processing transits SCC-protected US partners (Retell, ElevenLabs, Anthropic) — full breakdown on /subprocessors. Recordings auto-deleted after 30 days (Solo) or 90 days (Pro).
Solo handles callbacks too — Plus does it differently
What's only on Plus
120 appointments per month (instead of 40)
Three times the volume. For owners whose phone genuinely doesn't stop.
Connect 2 calendars
Two services with different schedules? Two team members? Two locations? Connect both Google Calendars, Tirza books in the right one.
Urgent caller? Phone within 60 seconds, not the daily summary
Solo gets every callback in the daily summary. Plus detects when a caller signals urgency ("emergency", "leak", "please ring back today") and texts your mobile inside a minute. Solo will still pass on every callback — Plus just sorts the urgent ones to the top.
Expanded business FAQ
Tirza can answer more of your common questions before falling back to a callback. Fewer calls land on your plate.
Priority email support — 24h response
Email us on Plus, you get an answer inside a working day. (Solo support is best-effort, usually within two working days.)
