OpenEvidence has made its artificial-intelligence-integrated doctor dialer feature more widely available as it expands its reach into more clinical workflows.
The dialer communications tool enables HIPAA-secure, privacy-centric calling, messaging, faxing and straight-to-voicemail capabilities directly within the OpenEvidence app, according to the company. OpenEvidence announced the new dialer feature in early December and is now making it more widely available.
The OpenEvidence dialer includes unlimited daily minutes and is free for all verified U.S. healthcare professionals, the company said.
OpenEvidence developed an AI-powered medical search engine and a generative AI chatbot exclusively for doctors that summarizes and simplifies evidence-based medical information. The fast-growing health tech company is expanding from clinical search into other clinical workflows that puts it into more direct competition with other healthcare AI companies. In August, the company rolled out its Visits feature, a clinical AI assistant that transcribes patient visits. With the dialer feature, OpenEvidence is directly taking on Doximity's core business.
OpenEvidence says its AI-integrated doctor dialer feature is built on multistep AI that operates throughout the entire clinical workflow, from call documentation to real-time clinical decision support during the patient call, with evidence-based recommendations embedded directly within the patient notes generated from the call.
The tool unifies patient communication, clinical decision support and documentation into a single workflow, according to OpenEvidence, which makes it distinct from traditional standalone dialers and fragmented “communications add-ons."
“We developed the OpenEvidence AI-Integrated Doctor Dialer because clinicians faced an impossible choice between privacy and patient pickup rates, while juggling fragmented tools for every aspect of patient communication, documentation and clinical decision support," Daniel Nadler, Ph.D., founder and CEO of OpenEvidence, told Fierce Healthcare.
"We saw dialers across the industry that, because they were essentially still COVID-vintage telehealth products, couldn't deliver the type of clinical decision support enabled by modern tools like OpenEvidence. OpenEvidence AI-Integrated Doctor Dialer is the first communications platform, covering calling, messaging, faxing and voicemail, with clinical decision AI deeply integrated throughout the entire workflow, providing real-time decision support and automatically generating evidence-based clinical notes, all HIPAA-compliant and unified in one place," he said.
With the OpenEvidence dialer, clinicians can place calls with customizable caller ID name and number set to their hospital or practice—increasing patient pickup rates while maintaining personal privacy—make sure calls are answered with custom caller ID, connect with patients over telemedicine in one tap, switch between profiles and phone numbers across multiple hospitals or clinics and boost pickup rates by ensuring patients see the right caller ID name and send and receive secure text messages directly within the OpenEvidence app, with optional patient replies.
With the dialer tool, physicians can also send and receive faxes by uploading files or scanning documents in-app, deliver straight-to-voicemail messages without ringing the patient’s phone—ideal for appointment reminders, follow-ups and other nonurgent communications. And physicians can automatically create clinical notes using the Visits feature to transcribe patient calls into structured documentation with real-time evidence integration.
Since the limited release of the Visits feature in August, OpenEvidence says the tool has already been used to power 37 million minutes of doctor-patient care communications and interactions.
In late January, OpenEvidence banked $250 million in series D funding to invest heavily in the R&D and compute costs associated with its multi-AI agentic architecture. OpenEvidence will also use the funding to continue to build out its content licensing partnerships.
The series D round doubled its valuation to $12 billion, the company said. The company's valuation stood at $6 billion in October when it raised $200 million in series C funding—and that was just three months after it raised $210 million in a series B funding round in July.
OpenEvidence has raised roughly $700 million in the past year.
The company has seen breakneck growth, and, in December alone, it claims it supported about 18 million clinical consultations from verified physicians in the U.S., up from about 3 million consultations per month a year ago. OpenEvidence is now actively used daily, on average, by more than 40% of physicians in the U.S., spanning more than 10,000 hospitals and medical centers nationwide, according to the company.
The company asserts that 100 million Americans were treated by a doctor using OpenEvidence last year.
The company now has set its sights on building specialist AI models to evolve its platform, Nadler said at the 2026 J.P. Morgan Healthcare Conference, as he made the case for developing “medical super-intelligence” based on agentic AI that is multimodal and multicloud.
