how it works

Four steps. That is the whole thing.

Username, password, model. Then send.

01

Make an account

Pick a username. That is also your starting display name. Both are editable later in Settings.

02

Pick a model

Aero Max for depth, Aero Mini for speed. Each chat locks in its own choice on the first send.

03

Ask anything

Text, code, a webpage, a chart, an essay. Drop in files, paste images. The model sees all of it.

04

Watch it render

Self-contained output opens in a side viewer. Switch tabs, switch devices. The reply persists either way.

faq

Quick answers.

A side viewer that opens when the model produces something self-contained. HTML renders, SVG paints, Mermaid draws, markdown typesets, math runs through KaTeX. Long code goes there too.
Aero Max for depth, Aero Mini for speed. Both live in the same picker. New Aero models drop in as they ship.
Yes. Paste a screenshot or drag a PNG, JPG, or text file. Images go in as vision inputs, text comes in as content.
Locked to your account. Nobody else reads them, me included. Delete a chat and its messages go with it.
Yes. The layout collapses cleanly. The composer's drag-drop and clipboard tricks work on mobile too.
