Arine vs FeelBetter (2026)
Both find the patients whose medication list has become the problem, and they sell that to different buyers with different economics behind it. Arine sells medication intelligence to health plans, working across a membership and reporting savings per engaged member, with a HITRUST risk based certification that is the most demanding tier of that programme and the strongest security posture in this part of the category. FeelBetter targets polypharmacy in older adults specifically, stratifying by risk of near term deterioration or hospitalisation, and has peer reviewed work behind it, though the published study measured something narrower than the company's marketing claims. If you are a plan, Arine is built for your data and your contracting. If you are a provider group or a pharmacy service managing complex elderly patients, FeelBetter is aimed at the clinical problem rather than at the medical loss ratio.
- The buyer and the workflow are payer side, ingesting clinical, socioeconomic and behavioural data across a plan's membership to find members at risk before an event rather than reviewing a hospital's inpatients.
- HITRUST risk based two year certification, attained in 2024, is the most demanding tier of that programme and the strongest security position in this part of the category.
- Results are named to real clients with quantified savings per engaged member, which is more commercial specificity than most vendors here provide even though it is self reported.
- The population is the sharper target: older adults on enough medications that the regimen itself is the hazard, stratified by risk of near term deterioration or hospitalisation rather than by generic medication burden.
- There is peer reviewed work behind it, and the useful part is the gap between what the study measured and what the company claims, which a buyer can read and judge for themselves.
- The oversight chain is conventional and sound, with recommendations reaching a clinical pharmacist and any change still requiring a prescriber.

Side by Side
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 Arine its top capability grade on AI Centrality. Set against FeelBetter, Arine grades higher on AI Safety and PHI Stewardship, HIPAA and BAA Posture and Security Certifications and Trust Center. Its thinnest published disclosure sits on several axes, including Model Supply Chain Disclosure, AI Governance and Bias Disclosure and AI Liability and Recourse. 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 Arine or FeelBetter?
On the axes where the AI Health Index separates them, Arine grades higher on AI Safety and PHI Stewardship, HIPAA and BAA Posture and Security Certifications and Trust Center, and FeelBetter grades higher on Clinical and Operational Evidence and AI Liability and Recourse. Arine 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 Arine and FeelBetter differ most?
The widest separation the AI Health Index records between Arine and FeelBetter is on HIPAA and BAA Posture, where Arine grades B and FeelBetter grades D. 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 Arine and FeelBetter grade the same?
The AI Health Index grades Arine and FeelBetter the same on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. 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 Arine and FeelBetter not disclosed?
At the last review, at least one of Arine and FeelBetter published thin or absent detail on several axes, including Model Supply Chain Disclosure, HIPAA and BAA Posture and Security Certifications and Trust Center. 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.

Both vendors sell outcomes that are measured by the party being paid for them. Arine's savings figures above a stated amount per engaged member are entirely self reported, and FeelBetter presents impact metrics as labelled categories rather than as a study, so ask both for the denominator, the comparison group and who computed the result.
FeelBetter publishes no located HIPAA statement, business associate terms, security attestation or trust centre, and no subgroup performance or bias assessment, which is a wide gap for a product stratifying an elderly population. Neither publishes pricing.
