What AI medical scribes actually do
An AI medical scribe — often called an ambient scribe — records the clinician-patient conversation (with consent), separates small talk from clinical substance, and drafts a structured note, usually straight into the EHR. The appeal is arithmetic: clinicians routinely report an hour or more of documentation handed back per day, and the tools have matured from novelty to standard-of-care purchases at large health systems.
The market splits cleanly in two. Individual and small-clinic tools (Freed, Heidi, Nabla, PatientNotes, Sully) can be bought with a credit card, often have a free tier or trial, and publish pricing. Enterprise platforms (Abridge, DeepScribe, Suki, Ambience, Corti) are sold to health systems, integrate deeply with the EHR, and add coding and compliance layers. Knowing which side of that line you shop on eliminates half the demos.
One honest note before the list: nearly every "best AI scribe" ranking on the web is published by one of the vendors. This one draws on our independent ambient clinical scribes directory — we sell nothing and hold no affiliate links.

The scribes in detail
1. Freed
Freed made its name with a simple promise: an AI scribe an individual clinician can buy without asking anyone's permission. It listens to the visit, drafts a SOAP note in the clinician's own style, and improves as edits are made. Pricing is published per clinician per month — rare in this market — and there is a free trial, which is why Freed keeps showing up in small practices that could never run an enterprise procurement. Visit Freed.
2. Heidi Health
Heidi is the most generous free option among serious scribes: a working free tier, structured notes, referral letters and specialty templates. It grew by letting clinicians try the product on real consultations at no cost and upgrading when volume demands it. A strong first stop if you want to feel what ambient documentation is like before spending anything. Visit Heidi.
3. Nabla
Nabla pairs an ambient assistant with specialty-aware templates and integrations into common record systems. Like Heidi it offers a free tier, and it has published peer-reviewed evaluations of its documentation quality — worth reading before any pilot, whatever tool you pick. Visit Nabla.
4. Abridge
Abridge is the name that comes up when a whole health system, not a single clinician, adopts ambient documentation. It integrates deeply with major EHRs, maps the conversation to structured, billable documentation, and is deployed across some of the largest hospital networks. Procurement, integration and rollout are measured in months — and that is the point: it is infrastructure, not an app. Visit Abridge.
5. DeepScribe
DeepScribe focuses on accuracy in specialty contexts — oncology and other fields where a generic note is not good enough — with customisation layers that let a department shape exactly how notes come out. Sold to organisations rather than individuals. Visit DeepScribe.
6. Suki
Suki started as a voice assistant and it shows: alongside ambient notes it takes dictation and voice commands, and files the result straight into the record system. Clinicians who already dictate tend to find it the most natural transition into ambient AI. Visit Suki.
7. Ambience Healthcare
Ambience writes the note and suggests the billing codes in the same pass, across a wide set of specialties. That coding angle is its wedge: documentation tools save time, but coding accuracy is where health-system finance teams see the return. Visit Ambience.
8. Corti
Corti approaches the space as a speech-and-reasoning platform for clinical encounters rather than a note-taking app — documentation, coding support and quality assurance, available as products and as an API for teams building their own clinical tooling on top. Visit Corti.
9. Sully.ai
Sully bundles the scribe with a broader clinical assistant: it answers questions, summarises charts and drafts notes. For a small practice that wants one AI helper rather than a documentation point-tool, that bundling is the draw. Visit Sully.
10. PatientNotes AI
PatientNotes is a lighter-weight option: capture the consultation context, produce structured notes and patient-facing summaries, keep the workflow simple. A fit for clinicians who found the bigger platforms more than they need. Visit PatientNotes.
How to choose
Three questions settle most decisions. Who signs the contract — you or your organisation? Where must the note land — copy-paste is fine for a solo practice, but EHR write-back is non-negotiable at scale? And what happens to the audio — the serious vendors delete it after processing and sign the agreements your privacy rules require. Then pilot on real consultations: ten visits, compare the draft to what you would have written, count the edits.
Solo or small clinic
Freed for published pricing and style learning; Heidi or Nabla to start free.
Health system
Abridge for scale and EHR depth; Ambience if coding accuracy is the business case; DeepScribe for specialty precision.
Special cases
Suki if your clinicians already dictate; Corti if you are building documentation into your own product.
The habit that matters more than the choice: the clinician signs the note, so the clinician reads the note — every draft, every time. For the wider category, including decision support and patient management, see the AI healthcare tools directory.
Frequently asked questions
The good ones produce a draft that needs light editing rather than a rewrite, and accuracy keeps improving — several vendors now publish peer-reviewed evaluations. But every tool on this page positions its output as a draft for clinician review, and that is how they should be used: the clinician who signs the note reads the note.
Individual tools run as monthly per-clinician subscriptions, and several publish prices or offer free tiers — Freed publishes its rate, Heidi and Nabla have working free plans. Enterprise platforms like Abridge, Suki and Ambience are quoted per organisation and typically bundled with EHR integration work.
The enterprise platforms integrate directly with major record systems and file notes automatically. Individual tools vary: some offer integrations, others produce a note you paste in. If EHR write-back matters to you, make it the first question of any demo.
With patient consent and a vendor that meets your jurisdiction's health-data rules, yes — that is the standard deployment model. Reputable vendors process audio securely, delete it after the note is produced, and sign the data-processing agreements your rules require. Confirm those three points before any pilot.
