No. Heidi Evidence is now part of Heidi and can’t be turned off. It’s included in your plan at no extra cost.

If you’re currently on a time-limited Clinician or Practice plan trial, you may have access to premium Evidence features such as Source Control, premium research sources, and Evidence in Ask Heidi (where available).

When the trial ends, you’ll still keep Heidi Evidence at no extra cost. To retain premium features, you’ll need to stay on the Clinician or Practice plan. If you return to your previous plan, you’ll keep Evidence, just without those premium features.

Access to Heidi Evidence on Practice and Enterprise plans is managed at the organisation level.

If you’ve lost access, this is usually related to your organisation’s rollout stage or plan settings. Please contact your Heidi account admin or internal lead for the most up-to-date information on access and timing.

Ask Heidi hasn’t been removed; it’s just shifted slightly to the right. The layout may look different, but functionality remains the same. Ask Heidi still supports in-session prompting and workflow assistance as before.

What’s new is Heidi Evidence, which expands access to citation-backed clinical answers. Evidence is available in the sidebar for clinical lookups outside a session. In supported regions, Evidence can also be accessed within Ask Heidi during a session.

No. Evidence is designed to support clinical decision-making with checkable summaries and citations. Always use your professional judgement and follow local policies and governance requirements.

Availability may depend on your region, plan, or organisation settings. If you’re part of a team, your admin may need to enable Evidence for your workspace. If you’re unsure who your admin is, check with your practice or team lead.

Team trials require an admin to log in to Heidi to start/enable the trial for the workspace. This can be any admin (not just the team owner).

Yes. If you’re eligible but an admin can’t log in (or missed the opt‑in), Support can manually enable the Evidence trial. What to send Support: your team name, the admin email address, and your team/workspace identifier (if available).

In-session access depends on your plan, usage limits, region, and organisation settings. If you’re in a team workspace, your admin may not yet have enabled in-session Evidence.

Yes, Heidi Evidence is available on web, desktop, iOS and Android.

Some sources require licensing, are region-specific, or sit behind paywalls. Access to these sources varies by plan and location.

Yes. Go to Settings → Evidence, then toggle off Clinical Considerations.

Evidence is grounded in curated clinical sources, such as clinical guidelines, medicines references, and primary research. Source availability varies by region, plan, and licensing.

Open the inline citations attached to key statements to review the original source material. Where available, excerpts are provided to support transparency.

The guideline may not be included in your region’s source set, may require separate licensing, or may exist in multiple editions. Adding details such as region, specialty, setting, and patient population can help refine results.

Citations can differ based on region, plan, configured source set (for example, Source Control presets), and timing of source updates.

In regions outside of the UK and the EU, you can access Evidence within Ask Heidi during a consult. Usage limits vary by tier.

If you are using Heidi in the UK or EU, Evidence is only available when launched from the side panel, separate to your session note.

Premium Evidence features are included in Clinician, Practice, and Enterprise plans. These may include unlimited in-session usage, access to premium sources (where available), and Source Control.

Practice and Enterprise plans also include team-level functionality, such as organisation-wide Source Control.

Yes. Source Control allows teams to shape which sources are prioritised in responses.

Where available, Source Control supports adding organisational documents and protocols via a shared Library.

Evidence is designed to be transparent and checkable. Citations are provided so you can review the original sources. Always apply professional judgement and follow local governance requirements.

Some sources may be behind paywalls, require separate institutional subscriptions, or be blocked by network settings. If a link fails, try another network or confirm your institutional access.

Check the publication date and version in the citation. If needed, refine your question to reference the latest guidance and compare multiple sources.

Evidence aims to prioritise sources aligned to your region. If local guidance is unavailable, it may surface broader international sources.

Use follow-up questions to narrow the population, setting, or decision context. Compare citations and prioritise the most authoritative and up-to-date guidance for your setting.

Add region, specialty, and setting details to refine your search. If it still doesn’t appear, it may not be available in your region’s licensed source set.

Yes. Evidence supports copy and export workflows to help you save or share outputs.

No. You will not be charged automatically when the trial ends. You would only be charged if you actively choose to change to the higher-tier plan.

You can confirm your active subscription at any time by visiting your Billing page. You should only see one active paid subscription.

Check your sources first: Confirm the right sources are selected. Try reducing the number of sources, as search can fail if there are too many.

If it still fails: Send us the Session ID from the affected run so we can review the logs and investigate what happened.

If you are using Heidi in the UK or EU, Evidence is only available when launched from the side panel, separate to your session note.

NHS UK accounts are excluded from Heidi Evidence. If you're using an NHS (UK) email address, you will remain on your current plan and will not be enrolled on Evidence.

This source is not currently available in Sources. UpToDate integration is in progress. If enabled, it is expected to appear as a selectable source within Evidence’s source control experience.

Yes, with one limitation. You can open Evidence in the sidebar while transcribing a session to look up clinical questions and references. This works in the UK and EU.

The feature that isn't available in the UK or EU is In-Session Evidence, which automatically appends Evidence content to the clinical note. That's restricted to other regions.
