Why practices switch

The difference that shows up in your week.

Phone is one channel, not the product

Arini does phone well. Riley does phone, plus reviews, plus AEO, plus recall, because dental front-office work isn't just calls.

Slack as command surface

Arini's results show up in Arini's dashboard. Riley's results show up in your Slack, the place your team already lives.

Outcome ledger, not call metrics

Arini reports 'X% of calls answered'. Riley reports 'X recovered appointments worth $Y', written to a per-tenant ledger you can take with you.

Same vertical depth, broader surface

Both ship dental packs. Riley's covers more of the practice: same level of care, more channels.

When to choose which

Not a fit for everyone. Honest take.

Choose Riley if

You want one AI handling phone + reviews + AEO + recall in Slack: fewer vendors, fewer logins.

Choose Arini if

You only need an after-hours phone agent and don't want a tool doing anything else. Arini's narrow focus is the feature.
