Click Evidence in the sidebar
Select sources
Enter a clinical question
Example questions you can ask:
"What are the RCH guidelines for pediatric asthma management"
“What are the colonoscopy screening guidelines for a 50 yo male with a family history of colon cancer?”
“When should I order a head CT for a patient with a recent head injury?”
“Does the dosage of ramipril have to be adjusted for renal impairment?”

When you ask clinical questions, Heidi Evidence will automatically provide answers with inline citations with links to sources you can verify.

Using Evidence in Your Workflow
Evidence is designed to support clinical thinking without interrupting your workflow, giving you fast, citation-backed information whenever you need it. Available only on the web browser currently.
Common use cases include:
Pre-clinic preparation, such as refreshing diagnostic criteria or reviewing guideline-based management
Quick checks during the day, when you want to sense-check information in the moment
Post-session reflection, to clarify uncertainties or review evidence after seeing a patient
Teaching and supervision, including providing information for clinical reasoning or referencing guidelines
Staying up to date, by exploring evolving recommendations and best practices
Inline citations and chat history is available to all Evidence users, including those on the free version. Use inline citations to review and further investigate information from sources. Chat history allows you to:
Revisit previous Evidence questions and answers
Continue research over time without starting from scratch
Maintain continuity when exploring complex topics
Get Evidence Pro to control your sources
In the free experience, Evidence selects sources automatically. With Evidence Pro, you decide which sources are used. With Source Control, you can:
Choose which sources Evidence pulls information from
Control and refine the evidence base used in responses
Align answers with preferred guidelines or references
To control your sources, choose from presets such as Primary Evidence or region-specific guidelines. Alternatively, you can choose specific sources yourself to tailor the evidence base to your needs.
Access to full source content may depend on whether you hold a separate subscription to that publisher or database.
Frequently Asked Questions
What sources does Evidence use?
Evidence prioritises trusted, region‑aware sources such as clinical guidelines, peer-reviewed literature, and medical databases. Answers include citations so you can verify quickly.
Do I have to pay for Evidence?
You can access Evidence for free in the Heidi sidebar with unlimited queries. Free access includes inline citations so you can see the references behind each answer.
If you want to access Evidence Pro features, you can start a 14-day free trial.
What’s included in Evidence Pro?
Evidence Pro is a paid experience that includes source control, allowing you to choose which guidelines, sites, or sources Evidence uses.
Why can’t I open the full source I see cited?
Some sources require a separate subscription (e.g. publisher or database access). Evidence can reference these sources, but full access depends on your existing subscriptions.
Why is Evidence billed separately from Scribe?
Evidence and Scribe are separate products. If you subscribe to both, you may see two line items while billing is being streamlined. Evidence can be used with or without Scribe.
Will I be charged automatically after the Evidence Pro trial?
You won't be charged automatically after your trial ends unless you add a payment method. If you do, we'll notify you before processing any charges.
Does Evidence connect to my patient sessions?
When used from the sidebar, Evidence is separate from patient sessions and is not linked to patient data.
Some users may have early access to a limited in-session experience, where Evidence can interact with your session to provide evidence-backed information and insights.
How should I use Evidence safely?
Evidence provides you with evidence-backed insights for research and knowledge purposes:
Always verify important details using the cited sources
Follow your local clinical policies and guidelines
You are the clinician - Evidence supports you, but does not replace professional judgement
Is Evidence available on mobile or desktop apps?
Not yet, Evidence is currently only available on Web to those with access.
Do you take ad funding or sell data?
No. We do not take ad money, and we do not monetise your data.
