What is available in the UK and EU
Evidence (outside sessions) is fully available in the UK and EU on all plans. You can use Evidence from the Heidi sidebar for unlimited clinical queries with inline citations, follow-up questions, chat history, copy and export, patient-friendly summaries, clinical calculators, and CPD/CME tracking.
Paid Evidence features are also available on eligible plans. These include Source Control (presets, domain filtering, blacklisting), premium sources such as NICE, NICE CKS, BNF, and BMJ Best Practice, and the personal or organisational Library for uploading documents and protocols.
What is not available in the UK and EU
In-session Evidence
In-session Evidence is not available in the UK or EU. You cannot access Evidence within Ask Heidi during an active patient session. This applies to all plans, including Clinician, Practice, and Enterprise.
Features that require in-session Evidence and are therefore not available in the UK or EU include:
Live clinical considerations (patient-context-aware evidence surfaced during a consult)
In-consult Evidence queries via the Ask Heidi bar
Patient-context-aware answers that reference the current session transcript
Patient and session linking
Patient and session linking is not available in Evidence for UK and EU accounts. You cannot attach a patient record or an active session to an Evidence conversation from the sidebar.
Why these restrictions exist
Heidi Evidence operates in the UK and EU as a non-medical-device product. It is classified for informational, research, and educational use only.
In-session Evidence with patient context would constitute clinical decision support, which requires medical device classification under UK MDR 2002 (as amended).
What this means for your plan
UK and EU clinicians on paid Scribe plans (Clinician, Practice, Enterprise) still receive all paid Scribe features. This includes unlimited Ask Heidi for documentation workflows, unlimited advanced templates, EHR integrations, team management, and all other Scribe functionality. The restriction applies only to the in-session Evidence component.
Out-of-session Evidence with Source Control, premium sources, and Library access is fully available on eligible paid Evidence plans (Evidence Plus, Clinician, Evidence Team, Practice, Enterprise).
Intended use in the UK and EU
Because Evidence operates as a non-medical-device in the UK and EU, it is intended to:
Support informational, research, and educational purposes
Enable discovery, review, and understanding of published clinical evidence, guidelines, and scientific literature
Provide non-patient-specific summaries of evidence with appropriate citations
Evidence in the UK and EU is not intended to:
Diagnose, treat, prevent, monitor, or manage any disease or health condition
Provide clinical decision support, treatment recommendations, dosing guidance, or triage
Generate patient-specific assessments or treatment plans
Replace or substitute the clinical judgement of a qualified healthcare professional
Multi-region organisations
If your organisation has clinicians in both the UK/EU and other regions (for example, a UK organisation with US-based offices), in-session Evidence can be enabled at a team or office level for users in supported regions. UK and EU users within the same organisation will remain on out-of-session Evidence only.
Contact your account manager or sales team to configure this.

FAQ
What is Out-of-Session Evidence?
Out-of-session Evidence is accessed via the sidebar panel. You open it from the Heidi sidebar at any time, independent of a patient consultation. You type a clinical question, get a citation-backed answer, and can follow up. It has no awareness of any patient or session. Think of it as a standalone clinical reference tool. This is what UK and EU users have access to, and it's unlimited on all plans.
What is In-Session Evidence?
In-session Evidence lives inside Ask Heidi during an active patient consult. Because it runs within a session, it can read the session context (the transcript, linked patient details) and factor that into its responses. This is where features like live clinical considerations come from: Evidence notices what's happening in the consult and proactively surfaces relevant guidelines or research based on the patient's presentation. On Clinician and above, this is unlimited. On Free, it's capped at 10 uses per month.
The practical difference is patient context. Out-of-session is generic ("What does NICE say about eczema management in adults?"). In-session has context from the note, and transcript ("Given this patient's history and current presentation, what does the evidence suggest?").
I am in the UK/EU and cannot see "Use in Session Evidence" prompts. Is this a bug?
No. In-session Evidence prompts are intentionally hidden for UK and EU accounts. This is expected behaviour.
Can I switch my Evidence region to access in-session features?
You can change your Evidence guidelines region in Settings to access different regional guidelines for out-of-session queries. However, this does not enable in-session Evidence. In-session availability is determined by your account region, not your guideline preference.
I am on a Clinician trial and expected to have in-session Evidence. Why is it missing?
If your account is registered in the UK or the EU, in-session Evidence is not included in any plan, including Clinician trials. All other Clinician features (unlimited Scribe, unlimited Ask Heidi for documentation, advanced templates) remain available.
Does this affect Heidi Scribe?
No. Heidi Scribe functionality is identical across all regions. The UK/EU restriction applies only to in-session Evidence and patient/session linking in Evidence.
I'm using an NHS (UK) email. Why don't I have Evidence or the new trials?
NHS UK accounts are excluded from Heidi Evidence and free trials that include Heidi Evidence. If you're using an NHS (UK) email address, you will remain on your current plan.
