Duo AI
Duo AI is the intelligence layer built into the HR Duo platform. It answers HR questions, drafts compliant documents and guides procedures for HR teams, line managers and employees, drawing only on your account data, never the open web.
What is Duo AI?
Duo AI, also called simply Duo or the HR Duo AI Assistant, is presented by its publisher as the intelligence layer built into HR Duo that knows your organisation. It is not a standalone product. It lives inside the HR Duo platform, within the HR Intelligence and HR Assist module, and it opens only from an HR Duo account. HR Duo itself is an HRMS and workforce management platform covering time, scheduling, absence, payroll, recruitment, performance and compliance.
The assistant is organised around four capability blocks: Organisational Intelligence, HR Question and Answer, Intelligent Document Generation, and Process Guidance. It combines three kinds of material: the customer's live HR data, approved templates and policies, and employment guidance written by the publisher's in-house HR professionals. That grounding is the whole argument. Duo AI does not search the public internet and does not mix external data with the customer's records. Answers point back to the company's own policies and documents and are aligned with UK and Irish employment law, and the assistant escalates explicitly when a situation calls for human HR judgement.
Access follows role permissions, so each user only sees what they are entitled to see. HR teams get answers instead of tickets, line managers get a defensible position before acting, and employees can check their own leave, contract and training records without emailing anyone. Documents come back pre-filled from data already held in HR Duo, then get edited, saved, emailed or sent for electronic signature without leaving the platform.
There is nothing to deploy: no setup, no integrations to manage, no extra software. The same HR Duo credentials open the assistant, on desktop and mobile, around the clock, and the publisher announced in May 2026 that Duo is live for all HR Duo users.
Two boundaries matter. HR Duo positions Duo AI against general-purpose assistants, naming ChatGPT, Claude and Gemini as what it is not. And HR Duo separately ships three other AI features - a job description generator, CV anonymisation, and document translation into 30+ languages - which are not Duo AI. The 250+ UK and Irish policy templates the assistant draws on are likewise a platform asset, kept current with legal change.
What it does
- Ask an HR question in plain language and get an answer drawn from your own company data and policies
- Look up an employee record: start date, contract type, notice period, contracted hours, manager, site
- Check a leave balance or a sickness absence record
- Surface the internal policy that applies, from discipline and remote work to maternity and leave carry-over
- Draft a pre-filled employment contract from approved templates and recruitment data
- Generate a compliant HR letter such as a probation extension, a performance improvement plan or an invitation to a meeting
- Work through a disciplinary, grievance, absence or performance procedure step by step, with a warning when a required step is missed
When to use Duo AI / When not to
A quick filter to help you decide if Duo AI is the right fit.
When to use Duo AI
- Existing HR Duo subscribers, since Duo AI is only reachable from an HR Duo account and is not sold separately
- HR teams swamped by repetitive queries about leave balances, contracts and internal policies
- Line and frontline managers who need an immediate, policy-backed answer without queuing for HR
- Employees who want self-service access to their own records, leave balances, training history and policies
- Multi-site UK and Ireland employers with deskless, shift-based workforces in construction, healthcare, hospitality, retail, manufacturing or logistics, who need documents aligned with local employment law
When not to use Duo AI
- Organisations that are not HR Duo customers: Duo AI is neither sold nor usable on its own
- Anyone looking for a general-purpose assistant, since it stays strictly inside HR and never browses the web
- Employers outside the UK and Ireland, whose guidance and templates are explicitly calibrated to British and Irish employment law
- Buyers who want to trial an AI assistant before committing, as there is no free trial and the way in is a demo followed by a quote
- Payroll bureaus without software, companies under ten employees with no scheduling to manage, and complex multi-country payroll of the large-enterprise HRIS kind, all of which the publisher rules out for the HR Duo platform itself rather than for Duo AI
How to use Duo AI
A typical end-to-end flow, from setup to results.
- Check that your organisation subscribes to HR Duo: Duo AI only exists inside the platform and cannot be bought separately
- Sign in to HR Duo at my.hrduo.com with your usual credentials - there is no install, no integration to configure and no extra software to learn
- Open the assistant from desktop or mobile; it is available around the clock and already reflects your role permissions
- Ask a question in plain language, for example "How much annual leave does [Employee Name] have left this year?" or "What's the company policy on sick leave?"
- Read the answer with its sources: the assistant points to the company policy or document it relied on, so you can open it
- Ask for a document when you need one, such as "Create a contract for [Name], starting as [Job Title] in [Month]." or "Draft a probation extension letter for [Employee Name]."
- Review and edit the draft, which arrives pre-filled with the employee data already held in HR Duo
- Save it, email it, or send it for electronic signature directly from HR Duo
- For a formal case - disciplinary, grievance, absence, performance - let the assistant walk you through it: it lists what has been done, what comes next, warns you if an important step has been missed, and links straight to the letters, policies, contracts and forms involved
- Point employees at it for self-service, and use the publisher's published set of 45 example prompts to widen usage across the team
Pros & Cons
Pros
- Grounded in the customer's real data: answers come from the HR Duo account rather than from the open web
- Answer scope is capped by role permissions, so information does not leak sideways between users
- Guidance and templates are written by the publisher's in-house HR professionals, not merely generated
- Claimed alignment with UK and Irish employment law, drawing on a template library the publisher maintains as the law changes
- Nothing to deploy: built into HR Duo, same login, no installation and no integrations to connect
- Covers the whole chain from question to document to procedure, including electronic signature, without switching tools
- Available 24/7 on desktop and mobile, employees included, with data hosted in the UK or the EU and a Data Processing Agreement for every client
Cons
- Inseparable from HR Duo: unusable without a platform subscription and not sold on its own
- No price of its own is published, and the platform it rides on is quote-only
- No free trial, which the publisher states explicitly; the only way in is a demo
- Compliance value is confined to UK and Irish employment law
- The publisher says nothing about whether customer data is used to train models, and documents no opt-out
- No underlying model or AI provider is named, and no list of sub-processors is published
- No API documentation exists for Duo AI, and no interface languages are declared for the assistant itself
Pricing & Plans
No price is published for Duo AI itself. The assistant is delivered inside the HR Intelligence and HR Assist module of the HR Duo platform, so any figure quoted is the platform's, not the feature's. HR Duo states: "Our pricing is designed to fit your business, not the other way around. Get in touch with our team to request a quote." A quote is built on two declared variables: the modules selected - Workforce Management, HR Assist, EmployPath, or a combination - and the number of active employees managed, since "You only pay for active users managed within the platform". No amount, currency or entry-level tier is disclosed, so no lowest price point can be stated. There is no free trial either: the publisher writes "We don't offer a free trial", and offers expert-led demonstrations instead. No free plan is mentioned anywhere on the site, and none is explicitly ruled out. Under the terms, subscriptions are billed in advance and are non-refundable except where law or contract provides otherwise, monthly or annual billing is contemplated, and a plan can be changed later through support.
Data, GDPR & hosting
A consolidated view of how Duo AI handles your data.
GDPR overview
Compliance is claimed explicitly rather than implied. The privacy policy states that "Our policy complies with the Data Protection Act 2018 (Act) accordingly incorporating the EU General Data Protection Regulation (GDPR)", and the security page adds UK GDPR and Data Protection Act 2018. HR Duo says "every client is protected by a Data Processing Agreement", and that third-party processors are bound by strict data protection agreements, although no list of those processors is published. The rights described are access, correction and deletion, exercised at privacy@hrduo.com after identity verification, with unsubscribe@hrduo.com for marketing opt-outs. Complaints are directed to Ireland's Data Protection Commissioner. Two gaps stand out: no Data Protection Officer is named, and no EU representative under Article 27 is designated anywhere on the site. The terms were last updated on 7 April 2026.
Who owns the data?
Duo AI adds no store of its own: it reads only what already sits in the customer's HR Duo account, so the employer stays in control of its workforce records. The publisher states that, apart from listed exceptions, it does not share, sell or disclose to a third party any information collected through its website, and does not sell or share personal data for commercial gain. Employees view and update their own details by signing in, and request a copy or a deletion at privacy@hrduo.com after an identity check. Internal access is restricted by permissions and two-factor authentication, and Duo AI answers only within each user's role permissions.
Reuse rights
The material Duo AI reads is the customer's own: contracts and digital documents, compliance policies and templates, profile and job data, and absence, working-time and employment history. HR Duo states that the assistant "only draws from the live data, templates, and policies stored in your HRMS" and that, "unlike generic AI tools, Duo does not search the public internet or mix external data with your records" - no browsing, no outdated results, no exposure of sensitive company or employee information. Role permissions cap what each user can surface, so the same question returns different scope depending on who asks. The legal bases displayed for processing are contractual necessity, consent for marketing and cookies, legitimate interest and legal obligation; transfers outside the EU for outsourced services are framed by approved contractual clauses or binding corporate rules. One silence is worth naming: the publisher never states whether customer data is used to train models, nor whether an opt-out exists.
Data retention & training
Hosting summary
HR Duo states that all its data, biometric data included, is stored either in the Microsoft Azure UK South region or in the Amazon AWS EU-West-1 data centre, "keeping your data within UK and EU regions", under a UK and EU data residency banner and a regional data centres only commitment. The websites themselves are described as hosted in the European Union. Storage sits on a private cluster, with encryption at rest and in transit, two-factor authentication on access, and sensitive data segregated and tokenised. Hosting partners are described as aligned with standards such as ISO 27001, though the publisher claims no certification of its own. Two qualifications apply. Outsourced services supporting other parts of the business may involve transfers outside the EU, framed by approved contractual clauses or internal group rules. And the domain's public IP resolves to a Cloudflare anycast node in the United States, which is the marketing site's CDN and not the location of HR records. No hosting arrangement specific to Duo AI is published: the assistant runs on the platform's infrastructure.
Things to keep in mind
Risks and trade-offs to weigh before adopting Duo AI.
- Access is locked to an HR Duo subscription, with no published price and no free trial, so the commitment has to be made before the assistant can really be tested
- Guidance and templates are calibrated to UK and Irish employment law; used elsewhere, an answer that sounds authoritative may carry very little compliance value
- Step-by-step process guidance is convenient enough to become a substitute for judgement: it is easy to follow a checklist through a disciplinary or grievance case without reconsidering the case itself, and while the assistant escalates when it recognises the need, that recognition is the assistant's rather than yours
- No underlying model and no AI provider are named, so users cannot reason about known failure modes or about where their prompts are processed
- Nothing is said about whether customer data is used to train models, nor about any opt-out; that is a silence rather than a denial, and it belongs in the Data Processing Agreement conversation
- No sub-processor list is published even though Azure and AWS are named as storage locations, and the cookie inventory is not a substitute for one
- Two easy confusions to avoid: the marketing site's IP resolves to a Cloudflare anycast node in the United States, which says nothing about where HR records are stored, and HR Duo's three other AI features - job description generation, CV anonymisation and translation into 30+ languages - are not Duo AI. The publisher is also a three-entity group across the UK, Ireland and Romania, so the contracting party depends on the contract
Setup & Integrations
Technical difficulty
None for Duo AI itself. The publisher states there is "no extra setup, no integrations to manage, and no additional software to learn": the assistant works from day one with an existing HR Duo login, and using it takes no technical skill, since you simply type a question. It is described as fully integrated across the HR modules rather than a bolt-on. The real effort sits one level up, with the HR Duo platform, whose implementation path involves a named implementer, super-users, data migration, configuration and training. That is the platform's cost of entry, not Duo AI's.

Should you pick Duo AI?
Duo AI is a deliberately narrow HR assistant, and the narrowness is the argument. It does not try to be a general chatbot: it reads the customer's own HR Duo records, the approved templates and policies stored alongside them, and employment guidance written for UK and Irish law by the publisher's in-house HR team. Because it never browses the web, it answers about your organisation rather than about employment law in the abstract, and because role permissions bound it, it answers differently depending on who is asking.
The absence of any deployment step matters more than it sounds. HR teams without technical resources get the assistant on day one with existing credentials, on desktop and mobile, and the chain from question to document to electronic signature stays inside a single tool.
The trade-offs are just as plain. Duo AI cannot be bought on its own, carries no price of its own, and the platform that hosts it is quote-only with no free trial, so the first step is always a demo and a sales conversation. Its compliance value falls away outside the UK and Ireland. And there are silences to accept: HR Duo names no underlying model and no AI provider, publishes no list of sub-processors, and says nothing about whether customer data is used to train models or whether an opt-out exists. None of that is an accusation, it is simply undisclosed, and it belongs on the agenda before signing.
For a multi-site, shift-based employer in the UK or Ireland already running HR Duo, or seriously considering it, Duo AI is a credible way to absorb repetitive HR queries and to produce documents that follow local law. For everyone else, the entry ticket is the platform itself, and that is the decision to make first.
