Papago ended its trial phase and officially launched on July 19, 2017, with translation options for Korean, Japanese, Chinese, English, Spanish, and French. It was only available as a smartphone app but it has since launched its own website and has expanded to other languages.

From November 2019, Papago was changed to be available without Internet service.

In 2020, the image translation function was introduced, and text in photos can be translated directly. It supports a total of six languages, including Korean, English, Japanese, Chinese, Vietnamese, and Thai.
