The short answer
Choose Zanda if you want a broad practice system on a budget: client portal, e-signed forms, two-way SMS, session packs and Xero, from £15 a month. Its built-in AI scribe is limited to 4 sessions per practitioner a month unless you add AI Pro at £19.
Choose NoteSono if notes are the job you want taken off your plate. Every paid plan includes unlimited AI notes in 20 therapy formats, plus CORE-10, PHQ-9 and GAD-7, from £14.99 a month, with a free plan to start.

Where Zanda is better
For a single practitioner, Zanda gives you a lot of practice-management machinery for the money. NoteSono does not yet match it on these:
- Client portal. Clients can book, cancel within your notice window, pay invoices, complete forms and download documents.
- E-signatures on forms and consent documents.
- Two-way SMS at £0.09 a message, with free replies.
- Payments. Deposits at booking, stored cards and session packs.
- Xero integration and automated reminders for unpaid invoices.
- Note history. Previous versions of a note can be restored for 30 days.
- Certification. Zanda publishes an ISO 27001 certificate and a data processing agreement with UK transfer wording.
Zanda also offers a 12-month money-back guarantee, which is unusual.
Where NoteSono is better for talking therapists
AI notes without a monthly cap
Zanda's included AI covers 4 scribe sessions per practitioner per month. A therapist seeing 15 clients a week would need AI Pro, which adds £19 a month per user. NoteSono's paid plans include unlimited AI notes.
No recording needed
Zanda's scribe records the session. Some clients will not consent to being recorded, and some therapists do not want to ask. NoteSono works from the summary you give after the client has left, so nothing in the room is recorded.
Therapy formats and measures ready to use
Zanda's feature pages mention SOAP only in testimonials and do not name DAP or BIRP. Its scored assessments are generic forms you build. NoteSono comes with 20 therapy formats and scores CORE-10, PHQ-9 and GAD-7 for you, with charts on the client record.
Built for one kind of practice
Zanda serves many professions, so menus and settings cover physiotherapy, dietetics and more. NoteSono's screens, wording and templates are written for counselling and psychotherapy.
What each costs with unlimited AI notes
| Per month, one practitioner | Zanda | NoteSono |
|---|---|---|
| Practice software | £15 (Starter) | £24.99 (Pro, with calendar, booking and invoices) |
| Unlimited AI notes | +£19 (AI Pro) | Included |
| Total | £34 | £24.99 |
| Notes only, no diary or invoices | Not sold separately | £14.99 (Essentials) |

Common questions
Is Zanda the same as Power Diary?
Yes. Power Diary rebranded as Zanda. Some review sites still list it under the old name.
How many AI notes does Zanda include?
Zanda's AI Core, included in its plans, covers 4 AI scribe sessions per practitioner per month. Unlimited scribing needs AI Pro, listed at £19 per user per month in October 2026.
Does Zanda host data in the UK?
Zanda's security page says data is hosted in the UK in line with UK GDPR. Its sub-processor list describes its AWS hosting as multi-region, selected by the customer. NoteSono stores data in the EU.
Does Zanda have a mobile app?
Not a native one, as of October 2026. Zanda works in a mobile browser. NoteSono is an installable web app that works the same way on phones.
Can NoteSono replace Zanda completely?
Not for everyone yet. NoteSono has no client portal, e-signatures, SMS or Xero integration. If you rely on those, keep Zanda for admin and consider NoteSono for notes only.
