How was this comparison written?
From each company's own website, and nothing else.
Everything stated here about Johnni was read off johnni.ai, first on 19 August 2026 and again on 13 October 2026, and the pages are linked in the sources at the bottom. Nothing is inferred from what a competitor “probably” does, and where we could not verify something, the page says so rather than filling the gap.
We sell a competing product, so read it with that in mind. Every claim below is one we can show you on their own website, which is more than most comparison pages will offer you in either direction.
What is Johnni AI?
Johnni is an Australian AI receptionist, built and run from Brisbane, for trade and service businesses. Their own description is that it answers 24/7 and “books the job straight into ServiceM8, Simpro, your CRM or calendar while the caller is still on the line.”
Their homepage names ServiceM8, Simpro, ServiceTitan, HubSpot, Pipedrive, Zoho and Google Calendar. Google Calendar comes on every plan; the job-software and CRM connections are custom integrations, quoted to your setup, according to their pricing page.
We work the same way. You keep ServiceM8 or whatever you run, we connect to it, and we confirm any cost for that before you pay. Bookings drop straight into your jobs and the review text goes out when you close the job off.
Also named on their site: after-hours and overflow handling, warm transfer to a human, a service-area check, memory across calls, outbound AI calls and callbacks to new leads, voice and text chat on your website, appointment reminders, call recordings and transcripts, and their own CRM included if you do not run one. SMS notifications are an add-on.
What is OP Digital?
A Perth-based agency that builds and runs the front end of service businesses across Australia. The managed system handles enquiries from the first response through to booking and follow-up, with AI reception and Google review automation, for one monthly price, and a website is included if you need one. Not everyone does. If a website is all you need, we build that on its own as a one-off.
We sell the loop rather than the parts, and that is deliberate. A website with nothing behind it is a brochure. Call handling pointed at a site that does not convert is money into a hole. Reviews nobody asks for do not arrive. Those three things are one job, and buying them from one person who owns the whole outcome is the difference between a system and a pile of subscriptions you have to make talk to each other.
Prices are published on the site: from A$499 a month for the managed system after a 14-day free trial, no setup fee, month to month, with unlimited inbound calls. Card required; billing starts on day 15 unless cancelled. A website on its own is a A$997 one-off build, live in 7 business days or it's free.
How do they compare side by side?
Johnni covers the calls; we cover the calls, the reviews and the website.
| Johnni AI | OP Digital | |
|---|---|---|
| What it is | An AI receptionist for Australian trade businesses. | The front end: call handling and review automation on a monthly plan, with a website included if you need one. |
| Builds your website | No. It talks to visitors on the site you already have. | Yes. Included in the monthly plan if you need one, or A$997 one-off for a website on its own, live in 7 business days or it's free. |
| Job-management integrations | ServiceM8, Simpro, ServiceTitan, HubSpot, Pipedrive and Zoho, as custom integrations quoted per business. Google Calendar on every plan. | We connect to job software with an open API, like ServiceM8, Fergus and simPRO, and confirm any cost before you pay. Google and Outlook calendars as standard. |
| Google review automation | Not listed on their site. | Included in the monthly plan. |
| Published pricing | Published. From A$44/month + GST paid annually (A$49 billed monthly), sized by call minutes, with a per-minute rate after that. | Published. From A$499/month for the managed system, website included if you need one. A$997 one-off for a website on its own. |
| Try before you talk to anyone | A demo number listed on their site, plus demo videos. | Our own AI receptionist, on a number you can ring without giving anyone your details. |
| Outbound lead callbacks | Yes, listed on their site. | Not in the standard plans. |
| Focus | AI call handling only, which is where all their development goes. | The whole loop, which means less depth in any one part. |
| Who you deal with | An Australian company with a team. | Sam, in Perth. One person, which cuts both ways. |
| Commitment | Month to month, no lock-in, 7-day free trial. | Month to month, no lock-in, 14-day free trial. |
Which one should you buy?
OP Digital, if you want the calls, the reviews and the website handled on one plan by one person who owns the result.
These are different products for different stages. Johnni adds a receptionist to a front end that already works. We build the front end. For a business owner who wants the whole thing handled by one person, that is the entire decision.
How do you decide?
Start from what is actually broken, then check which job software you run.
- Write down what is broken. If the answer is only “the phone”, buy a phone product. If it is the phone, the website and the fact that you have eleven Google reviews from 2023, that is the whole front end, which is what we build.
- Check your job-management system. If ServiceM8 or Simpro runs your business, ask both of us what connecting it costs, and get the answer in writing.
- Ring both. You can ring our own AI receptionist right now without giving anyone your details, and Johnni lists a demo number on their site. Two minutes each will tell you more than any comparison table.
- Ask both for the price in writing. Both of us publish a starting price. Get the full monthly figure for your call volume, plus any connection cost, written down before you commit either way.
- Ask what happens when you leave. With us, a website bought on its own is yours from day one, one built on the managed plan is yours from your second paid month, and the automations switch off. Ask them the same question about your data and your call recordings.
If it turns out you do not need a receptionist at all, the text-back or receptionist comparison is here and it is the cheaper conversation to have first.
