Reviewers mostly praise R2 Copilot for one thing: it feels safer to use than other AI assistants. They repeatedly highlight privacy, secure handling of confidential prompts, and peace of mind for business use. Users also say it fits smoothly into daily work, especially in Outlook, Word, and office workflows, where it saves time, gives consistent responses, and is easy to pick up. The main caveat is polish: a few reviewers note that the interface is basic and the feature set is still developing, even if it already gets the job done.
