"Proton Docs looks a lot like Google Docs: the whole deal. Proton has promised to never sell or otherwise use your user data, which may appeal to more people now that there are so many questions about how your documents are used to train AI models."

"The move to add encrypted documents to Proton is a shot at the data-hungry approaches of Google and Microsoft, which both don’t encrypt files and can collect vast amounts of data about people. It also makes Proton one of only a handful of businesses providing encrypted documents and editing online."

"Unlike Google, which is adding its Gemini AI across its Google Drive, Docs, Sheets, and Slides as a sidebar to review all your data to help answer questions and generate text and graphics, Proton isn't trying to add invasive AI to its products."

Secure collaboration for teams

For small teams, growing enterprises, and everything in between. Introduce Proton Docs and Sheets to your business to boost privacy and productivity with ease.
