Cedar vs Collectly (2026)
If your failure mode is picking a patient billing agent on headline collection lift, remember that a billing call is an emotionally charged conversation where a wrong answer can trigger an unwarranted payment or an avoidable trip to collections, so escalation design and incentive alignment matter more. Cedar builds for that directly: Kora uses sentiment and tone detection and escalates to a live agent with full context when human judgment is required, so a distressed caller reaches a person fast, and Cedar publishes unusual research on the uninsured patients its own category underserves. Collectly competes on breadth and attestation: its Billie agent works across more than 20 EHRs with a live bidirectional Epic integration, it holds the most complete security stack among these vendors including PCI DSS, and it prices as a subscription rather than a cut of collections.
- The strongest escalation design in this pair: Kora detects sentiment and tone and hands off to a live agent with full context when judgment is needed, so a distressed caller reaches a person quickly rather than restarting the conversation.
- An unusual equity disclosure: Cedar publishes research naming who its own category underserves, reporting that 40 percent of collectible dollars on its platform now come from uninsured patients, up 54 percent in three years.
- Checkable deployment evidence at named enterprise sites: nearly 400,000 Kora calls in year one across ten organizations, with Gastro Health alone past 60,000 since September 2025, against a 30 percent automation target published in advance.
- The most complete security stack among the patient financial vendors here: HIPAA, SOC 2 Type 2, PCI DSS, and HITRUST i1, and PCI DSS matters specifically because the product takes card payments, a separate risk surface from PHI.
- Integration breadth for billing that sits across every system a group runs: more than 20 EHRs via API or FHIR, plus a live bidirectional Epic integration listed on the Epic Showroom rather than a claimed capability.
- Incentive aligned pricing: a monthly subscription rather than a percentage of collections, which does not reward the vendor for pursuing more from patients, the structural question worth asking any collections vendor.

Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Cedar its top capability grade on Autonomy and Oversight Model and Setting and Specialty Coverage. Set against Collectly, Cedar grades higher on several axes, including Autonomy and Oversight Model, AI Safety and PHI Stewardship and AI Governance and Bias Disclosure. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Cedar or Collectly?
On the axes where the AI Health Index separates them, Cedar grades higher on several axes, including Autonomy and Oversight Model, AI Safety and PHI Stewardship and AI Governance and Bias Disclosure, and Collectly grades higher on HIPAA and BAA Posture, Security Certifications and Trust Center and EHR and Interoperability Depth. Cedar leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Cedar and Collectly differ most?
The widest separation the AI Health Index records between Cedar and Collectly is on Security Certifications and Trust Center, where Cedar grades C and Collectly grades A. That axis sits in the Regulatory and Compliance group, so it should carry the most weight for a buyer whose binding constraint is where regulatory exposure sits and who carries it.
Where do Cedar and Collectly grade the same?
The AI Health Index grades Cedar and Collectly the same on several axes, including AI Centrality, Model and Technology Transparency and Model Supply Chain Disclosure. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Cedar and Collectly not disclosed?
At the last review, at least one of Cedar and Collectly published thin or absent detail on AI Liability and Recourse. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.
Related comparisons
Other published head to head assessments involving these vendors or their closest peers. The full set for this category is on the Patient Voice Agents page.
Both are graded B on AI centrality because each layers a conversational agent over a payments platform that functions without it, and both leave a key number unpublished: Cedar does not report actual containment against its 30 percent target or resolution quality, and Collectly publishes no escalation threshold, which matters because a wrong billing answer carries financial consequence for the patient.
Collectly's collection lift figures of 75 to 300 percent are vendor and customer reported without baselines, and a range that wide suggests results depend heavily on the prior process. Cedar publishes no pricing and notes its cited metrics draw on 2024 to 2026 pilot data, so marketed figures may not reflect general availability. Cedar has not published a security attestation in retrieved materials.
