Side-by-side comparison
Mena vs Keymaster
Psychology-specific AI vs multi-sector operational ERP
Keymaster is a Portuguese operational ERP used across roughly 19 sectors, from auto repair shops to hairdressers, with psychology and mental health as one vertical. Mena is built only for psychology practice: it records and transcribes the session, drafts the note, and recalls context across sessions. Keymaster's public pages state no AI features.
The short answer
Keymaster is the stronger choice if you run a business that happens to include psychology — it is a horizontal operational ERP with quotes, suppliers, purchases, inventory and stock, sold across roughly nineteen sectors, with fifteen users included in every plan. Mena is the stronger choice if you run a psychology practice, because Keymaster states no AI capability and no psychology-specific clinical documentation.
Choose Mena if
- You want the session documented for you. Keymaster states no transcription, no summaries and no AI across the pages checked.
- You want psychology-specific records. Keymaster's clinical record is the same object it calls a service order in nineteen other sectors.
- You want fiscal documents communicated to the Autoridade Tributária automatically, not routed to a separate invoicing product.
- You want to know the price before you talk to sales. Keymaster's three core plans publish placeholders, not figures.
Choose Keymaster if
- You need real back-office depth — quotes, credit notes, suppliers, purchases, inventory and stock control.
- You have reception staff and several clinicians: fifteen users are included in each plan, so seats cost nothing extra.
- You want a free branded patient app, included in every module.
- You want an established local vendor with a real legal footprint, phone support and named Portuguese case studies.

Comparison based on Keymaster's own public pages (keymaster.pt), read on 17 August 2026. "Not stated" means the capability is not documented publicly — it is not a claim that the capability is absent. Keymaster's three core plans show placeholder prices, so its price is recorded as not published. Please verify current details with each vendor.
Criterion by criterion
What each platform actually does
These two products are not really in the same category, and the table is more useful once that is said plainly. Keymaster runs a business; Mena runs a clinical practice.
| Criterion | Mena.ai | Keymaster |
|---|---|---|
| AI clinical documentationThe clearest difference, and the reason the two are bought for different jobs. | Records and transcribes the session, drafts the clinical note, and organises the themes and thinking patterns you confirm. Included in every paid plan. | Not stated. Verified across six Keymaster pages. Its 'Módulo Inteligência de Negócio' at €40 per month is business intelligence, not AI, and is marked 'Brevemente Disponível' — announced rather than shipped. |
| Clinical recordThis is the category question, not a feature gap. | Psychology-specific documentation: structured session themes, an optional vocabulary of thinking patterns, validated questionnaires, and clinical memory carried between sessions. | The 'Folha de Obra Digital / Ficha Clínica Digital' — the same record renamed per sector, with a photo, video and exam gallery per clinical process. No psychology-specific templates or psychometric instruments are stated. |
| Back office and ERPKeymaster wins this outright, and it is a real advantage for some practices. | Billing and invoicing for a clinical practice. Mena has no purchasing, supplier, inventory or stock management, and is not trying to. | Quotes, invoices, credit notes, suppliers, purchases, sales, inventory and stock, plus staff management with permissions and action logging, and physical-clinic workflows such as equipment and room management. |
| Video sessionsRead the mechanism carefully; the two are not equivalent. | Video sessions built into the platform, so the session and its documentation are the same workflow. | Generates links for Google Meet, Microsoft Teams and Zoom. This is third-party link generation rather than teleconsultation inside the product, and the recording and documentation of that call sit outside Keymaster. |
| Portuguese invoicing and SAF-TBoth route through a certified third party. The difference is filing. | Fiscal documents are generated through Cegid Vendus, an AT-certified provider, and communicated to the Autoridade Tributária portal automatically. Invoicing is a tiered add-on from €14.99 per month. | States 'Integra com Softwares de Faturação (Opcional)' — Sage One, Moloni Flex, Moloni Pro — and that SAF-T is available directly in the integrated invoicing software. Compliance is real and is delivered by that third party, not by Keymaster, and no AT-portal communication is claimed. |
| Users and teamA genuine cost advantage for a clinic with reception staff. | Priced per practice tier, with team tooling in the higher plans and Enterprise for larger organisations. | Fifteen users are included in each of the three main plans, so adding clinicians and reception seats does not change the bill. A free branded patient app is included in every module, letting patients book, pay and view invoices and clinical history. |
| Published pricing and commitmentsHeld against both sides on the same standard. | Plan prices, the invoicing add-on, the annual discount and the trial length are all published, and EU hosting is stated concretely. | The three core plans show literal '--.-- €/mês' placeholders, so core pricing is quote-based. A 'Teste Rápido Grátis' is offered with no stated duration. No data-residency, encryption or RGPD marketing claim was found; its privacy policy positions Keymaster as a processor acting on the clinic's instructions. |

What it costs
Pricing, both sides, in full
This comparison is asymmetric and the asymmetry is the point: Mena publishes its prices and Keymaster does not. Figures exclude VAT, as published on 17 August 2026.
| Plan | Price | What it includes |
|---|---|---|
| Essential | €39.99/mo | Scheduling, video sessions, patient portal, billing, and the full clinical AI suite — recording, transcription, drafted notes, session themes and cross-session memory. |
| Intelligent | €79.99/mo | Everything in Essential, plus the advanced tooling for growing practices and small teams. |
| Enterprise | Custom | For clinics and organisations needing custom integrations, on request. |
| Plan | Price | What it includes |
|---|---|---|
| Three core plans | Not published | All three publish '--.-- €/mês' placeholders on the pricing page. Fifteen users are included in each. Pricing is obtained by quote. |
| Extra storage | €30 | A published add-on, and one of the few concrete figures on the pricing page. |
| Three further modules | €5 / €5 / €40 | Published prices, but all three are marked 'Brevemente Disponível' — announced, not yet available. The €40 one is business intelligence. |
- You cannot compare what is not published
- Keymaster's core plan prices are placeholders, so no honest per-month comparison against Mena's €39.99 is possible. That is a fact about the pricing page rather than a criticism of the product — quote-based pricing is normal for ERP — but it does mean the evaluation takes a sales call on one side and a page visit on the other.
- Fifteen users changes the arithmetic
- For a solo psychologist this is irrelevant. For a clinic with three clinicians and two reception staff it may well reverse the total cost of ownership, because those seats are included rather than billed. If you are a clinic, get the quote before assuming Mena is cheaper.
- Both charge separately for fiscal invoicing
- Mena's Portuguese fiscal invoicing is a tiered add-on: €14.99 per month for up to 170 documents, €49.99 per month for unlimited. Keymaster's route is an optional integration with Sage One or Moloni, which is a separate subscription with that vendor. Neither is included in the base price.
- Trial terms
- Mena offers a 14-day free trial that begins with a setup call. Keymaster offers a 'Teste Rápido Grátis' with no duration stated on its site, so we cannot tell you how long you get.
Mena prices from mena-ai.pt/pricing. Keymaster prices from keymaster.pt/precos, where the three core plans render literal placeholders rather than figures; IVA is added at checkout. We have not estimated the missing numbers, because an invented price is worse than an admitted gap.
Two approaches
A horizontal platform and a clinical one
Keymaster runs the operations of a business, and psychology is one of many sectors it configures itself for — its core record is a digital work order renamed as a clinical file. Mena does one job: the clinical record of a psychology session. If your bottleneck is stock, suppliers and quotes, Keymaster is the broader tool.
Keymaster strengths:
- Full back-office ERP: quotes, invoices, credit notes, suppliers, purchases, inventory and stock
- A free branded client app included in every module, where patients book, pay and view invoices and clinical history
- 15 users included in every plan, so reception and multi-clinician seats cost nothing extra
- A documented route to SAF-T through its integrated invoicing software (Sage One, Moloni Flex, Moloni Pro)
- Established Portuguese vendor with a published legal entity, phone support and named clinic case studies
- Operational depth: permissions, action logging, room and equipment management, printable service orders
Mena strengths:
- An AI clinical assistant that drafts your session note for review
- Automatic session recording with real-time transcription
- CBT session analysis that organizes the themes and thinking patterns you note
- Cross-session clinical memory that recalls your earlier notes as you prepare
- Built only for psychology, with psychology-specific templates and validated questionnaires
- Stated EU data residency, with GDPR and EU AI Act alignment
The honest part
When Keymaster is the better choice
Keymaster is an established Portuguese vendor with a real legal footprint and named local case studies. For several kinds of organisation it is the correct purchase and Mena is not.
- Your business is more than a psychology practice
- If you run a multidisciplinary centre, or psychology sits alongside other services under one company, Keymaster is built for exactly that. It sells into roughly nineteen sectors from one platform, so a single system covers the whole operation. Mena covers psychology and stops there — which is a limitation as well as a focus.
- Your bottleneck is the back office
- Suppliers, purchase orders, inventory, stock control, credit notes and printable service orders are things Keymaster does and Mena simply does not have. If you are managing materials, equipment or a supply chain alongside clinical work, no amount of AI note-taking substitutes for that, and Mena would leave you running a second system.
- You have a team and reception staff
- Fifteen users included in each plan, with permissions and action logging, is a meaningfully different commercial shape from per-tier pricing. A clinic with several clinicians and administrative staff should price both properly before deciding, because included seats can outweigh a lower headline subscription.
- You want an established local vendor
- Keymaster is Acordo Certo 2, Unipessoal Lda, with a published address in Cascais, a NIF, phone support and named Portuguese case studies including Oficina de Psicologia. If institutional solidity and a phone number matter more to you than clinical AI, that is a legitimate basis for the decision.
The dividing line is category, not quality. Keymaster runs the business around the clinical work; Mena runs the clinical work itself. If your hours disappear into notes rather than into stock and suppliers, that is the case for Mena — and if it is the other way round, Keymaster is the better buy.
When Mena fits
When Mena is the right fit
Keymaster suits a clinic that wants one system for its whole operation, including stock, suppliers and invoicing across several business lines. Mena suits a psychology practice whose costliest hour is the one spent writing notes.
- A clinical record, not a renamed work order
- Keymaster's clinical file is the same digital work order it gives auto shops and salons, relabelled per sector. Mena's record is designed around a therapy session from the start.
- The note is drafted for you
- Mena captures the session and prepares a summary you review and approve, so writing up takes minutes instead of evenings. You remain the author of every clinical judgement.
- Built for one profession
- Psychology-specific templates, validated questionnaires such as PHQ-9 and GAD-7, and cross-session clinical memory. Keymaster's public pages state no session notes, note templates or psychometric instruments.
- EU data residency, stated
- Mena stores data in the European Union and is aligned with GDPR and the EU AI Act, with transparent AI usage and audit logs. Keymaster's marketing makes no GDPR claim; its privacy policy positions it as a processor acting on the clinic's instructions.
Questions
Frequently Asked Questions
- What is Keymaster and who is it for?
- Keymaster is a Portuguese modular operational ERP from Acordo Certo 2, Unipessoal Lda in Cascais. It serves roughly 19 sectors, including auto repair shops, salons, veterinary clinics and equestrian centres, with psychology and mental health added as a vertical in July 2024. It covers scheduling, clinical files, invoicing, stock and a free client app.
- Does Keymaster include AI clinical notes or transcription?
- Keymaster's public pages state no AI features. Its "Módulo Inteligência de Negócio" is business intelligence, priced at €40 per month and marked as coming soon rather than available. Mena records and transcribes the session, drafts the note for your review, and recalls context from earlier sessions. Clinical decisions always remain yours.
- Is Keymaster built specifically for psychologists?
- Not exclusively. Psychology is one sector page over a shared platform, and Keymaster's own homepage calls the core record a "Folha de Obra Digital/Ficha Clínica Digital" — a digital work order that is renamed per sector. We found no psychology note templates or psychometric instruments stated on its site.
- How does invoicing compare?
- Both route Portuguese fiscal compliance through certified third-party software: Mena through Cegid Vendus, Keymaster through Sage One, Moloni Flex or Moloni Pro. Neither is more compliant than the other. What differs is automation, because Mena generates the fiscal document and communicates it to the AT portal without a manual step.
- How much does Keymaster cost?
- Keymaster does not publish its core plan prices. On its pricing page, all three main plans show placeholder dashes rather than figures, so a quote is required, and no trial length is stated. Mena's paid plans start at €39.99 per month with a 14-day free trial and no credit card required.
- Does Keymaster include built-in video sessions?
- Not natively. Keymaster describes the option of generating video calls through Google Meet, Microsoft Teams or Zoom, so the session runs in a third-party tool. Mena includes video sessions inside the clinical workflow, with recording and transcription attached to the session record.
