One chat

One chat. Everything in it.

Other chat apps spread your life across a dozen threads. Stella is one ongoing conversation — ask, follow up, get results, come back tomorrow. It's all right here.

One place

Everything you ask lives in one place.

Most chatbots want a fresh thread for every question, so your history ends up scattered and the context goes with it. In Stella there's just one conversation. The trip you planned last week, the email from this morning, the thing you're about to ask — same place, same Stella.

No waiting

Work runs in the background. Your chat stays open.

Ask for something big and Stella gets going on it without freezing the conversation. Keep typing, ask something else, step away — she brings the result back into the same chat the moment it's ready.

Nothing lost

No threads. So nothing falls between them.

There's no hunting for the chat where you asked that thing. Follow-ups, results, reminders, and scheduled work all land in the one conversation you already have — with the context still intact.

Any brain you like

Nothing to set up — or bring your own.

Out of the box, Stella runs on her own models. No keys, no accounts, no setup — just open the app and go. Prefer something else? Plug in Claude, Codex, Cursor, or your own key and Stella runs on that instead.

Built in

Pictures, voice, and more — on Pro.

Ask Stella to make an image, a video, a song, or a spoken reading, and she just does it. It runs on the house models with nothing extra to wire up, and it comes with the Pro plan.

One conversation, start to finish

Ask once. Keep talking.

One ongoing chat, with the work happening behind it — on Stella's models or yours. Running several jobs at once in the background comes with Pro; other plans work through one at a time.

Free. No credit card, no trial.
