What is Stella?
Stella is an emotional wellness AI from StellaLabs, offered as an iOS app and as a text-based chat in your messaging app. It is built for everyday emotional support rather than clinical care, and it is explicitly not a replacement for therapy or emergency help.
You start by saying what happened, out loud or in writing, including what you are afraid it means. Stella reflects your words back in plain language, gives a direct but kind take, and can help you choose what to say next, such as rewording a difficult text. It remembers details you mention, like an upcoming birthday, and you can set how blunt you want it to be. Each conversation ends with a one-line summary of where you landed, and past topics are tagged so you can review them.
