Tolan is an AI companion app made by Portola, a team based primarily in San Francisco, that lets users talk with an animated alien character whose personality adapts through conversation. The app uses conversation logs to build memory, helping it refer to earlier discussions, and it supports voice conversations, photo sharing and a virtual planet users develop with their companion. Topics include everyday decisions, personal interests and goals. New users receive a limited trial, while full feature access requires a subscription, and a Family Plan offers shared billing and individual companions. Tolan is available as an iPhone app with English listed as supported language, and it is intended for companionship and reflection rather than professional care. Potential considerations include that conversations are logged for memory, AI responses can contain inaccuracies, subscriptions renew automatically unless canceled, and the app is unsuitable as a substitute for professional care. It received an overall verdict of 3.7/5 stars.
