# Posh AI vs interface.ai: which conversational AI fits a community institution?

> Posh AI and interface.ai publish comparable integration lists and security attestations, so the choice turns on two things: Posh's customer alignment, with thirteen credit unions invested through a CUSO round, and interface.ai's authentication design, which is the better answer where voice fraud is the objection blocking the project.

## Choose Posh AI when

- Your digital banking platform is Q2, Alkami, Apiture, Lumin Digital or NCR and you want it on the vendor's published list
- You want the assistant to complete transactions on authenticated account data
- Vendor alignment with credit unions matters to your board
- You want employee-facing training and call scoring on the same contract

## Choose interface.ai when

- Voice fraud or deepfake risk is the objection stalling the project
- Your vendor diligence starts with ISO 27001 and SOC 2 Type II certification
- You want conversational AI and contact centre routing from one vendor, which interface.ai's Nexus launch targets
- Authentication design inside the AI channel is a board-level question at your institution

## Verdict

These two are closer than any other pair on this site, and both are credible for an institution under $10 billion. On the evidence a buyer can check before signing they are nearly level: both publish core and digital banking integrations, both state SOC 2 attestation, both sell collections and employee-facing products, and neither publishes pricing. Posh's edge is ownership, with thirteen credit unions holding capital in the business, plus a longer list of named digital banking platforms. interface.ai wins on the design question that stops these projects, which is what happens when a caller who might be a synthetic voice asks to move money. If your risk committee has already raised voice fraud, that argument will carry the room; if your problem is call volume and a legacy phone tree, either will do the job and the reference calls should decide it. Run both through the same quote cycle rather than assuming one is cheaper.

## Common questions

### Do both handle voice as well as chat?

Yes. Posh sells a Voice Assistant and a Digital Assistant, and interface.ai sells Agentic Voice AI and Agentic Chat AI. Voice carries its own integration work into the telephony stack in both cases.

### Which one is easier to verify before buying?

Both publish what a buyer needs for a first pass: integration lists, security attestations and named institutions on their own sites. Posh adds the CUSO round, with the thirteen investing credit unions named; interface.ai's case studies name the institutions and the results they reported. Neither publishes pricing.
