Its nen v2.0 model aims to respond directly, take a reasoned position, acknowledge uncertainty, and revise its view when given new information. Users can also choose nen-1, a briefer, more question-led dialogue option. The models are available on the web, iOS, and macOS, and are free to use, with a Pro subscription offered for $13 per month or $129 per year.

Alongside the model, nenspace provides a focused workspace for capturing and organizing thoughts without requiring a complex system. Its working memory lets people quickly record unfinished ideas, while notes, tasks, projects, folders, and a logbook help preserve and revisit useful information. Suggested destinations never take action without the user’s approval, and changes can be undone. The service is designed to keep both conversation and personal organization simple, emphasizing useful answers and practical space for drafts, decisions, and thoughts.
