Is this really private?
Yes. Writing Help is built on top of Private Processing technology, which allows you to leverage Meta AI to generate a response without Meta or WhatsApp ever reading your message or the suggested re-writes.
For those interested in learning more about the technical details behind Private Processing, we invite you to read our engineering blog and technical white paper that explains how this and other features we’re building work. From the start, we worked with our peers in the security community to stress-test and validate the architecture of Private Processing to help us continue to harden it. Today, independent researchers at NCC Group and Trail of Bits published their audit reports on the steps we’ve taken to evolve this privacy-preserving technology.
As always, we believe that you should be in control of your experience on WhatsApp. That's why using Private Processing features like Writing Help and Message Summaries are optional and are off by default.
Writing Help is rolling out in the English language, starting with the United States and several other countries. We hope to bring it to other languages and countries later this year.
