Don’t just take it from us

We understand that using our technology to promise privacy to your clients means that you’re putting your reputation into our hands, and we take that responsibility incredibly seriously. But don’t take our word for it – here’s what our partners have to say about us and our technology:

Curai - Senior Software Engineer, Full Stack (Remote)

Private AI scored best on our hybrid patient / provider PII test sets, and offers advanced features that we can customize to our needs.  We quickly got state-of-the-art performance on challenging de-identification tasks critical to our business, at a fraction of the cost of doing it in-house.

François Huet, Head of ML, Curai



Speech Analytics Software for Physical Retail

“I’m the CEO of a speech analytics startup. Our product analyzes conversations customers have with store associates in physical stores. As you can imagine, for us, being ahead of the privacy curve is not a nice to have, it’s a necessity. Especially because we have customers in California and the EU. From all of the PII redaction products we’ve seen out there (and believe me, we’ve seen all of them), Private AI is the best one by far in terms of accuracy, types of data that can be redacted, and flexibility of their models. After doing a side by side comparison it quickly became clear to us that we couldn’t go back to using something like AWS comprehend.”

— Sebastian Jimenez, Founder, Rilla Voice


“Private AI’s de-identification solution was extremely easy to integrate with our current pipeline, requiring only a few lines of code to ensure GDPR-compliant data handling for our users’ sensitive information. As a data anonymizer it was accurate and highly performant, allowing us to offer superior privacy protection without affecting our rates of service. Importantly, it enabled us to meet the rigorous data privacy requirements of the financial services sector without having to break the bank.”

— Damian Tran, CTO Minerva AI


“The docker image was really easy to integrate into our data workflows and we had it up and running in just a few hours. Our data involves mental health chat transcripts, so we were very happy to see that we were hitting impressive accuracy numbers out-of-the-box on a wide range of entity types that matter to our customers, saving us an enormous amount of time compared to building it ourselves. Plus their team was great to work with.”

— Quinn Underwood, CEO Autumn AI

“We provide a speech-to-text transcription API and needed to bring our redaction of credit cards, SSNs, and other personal financial and health information up to the highest accuracy level possible. Private AI made that quick and easy – now our accuracy numbers are through the roof and our clients are happy, which has been amazing. Plus they were remarkably easy to integrate into our existing workflows, which saved us a lot of time & effort compared to building something in-house, without our data ever having to leave our servers since we can run Private AI’s models on-premise.”

— Dylan Fox, CEO Assembly AI
