Preview, not live

The window you will get, browser or desktop

This is the Harness shell, drawn at real size: the same left column, the same model menu and effort setting, the same inspector rail. The conversation on this page is written into the page, not generated. When the hosted window opens, the free cloud models answer behind it with no account and no key, and nothing you type needs the desktop app to work.

Sample. The layout is real; the conversation is scripted. The hosted window is not online yet, so nothing here can answer you.

Ask me anything, or hand me a job. This window is the cloud session: it works on a phone or a work laptop with no install, and the desktop app is what adds local models, your own folders and plugins.

Summarise these release notes in three bullets and save it next to the file.
Rosalena

Done. Three bullets, written to notes-summary.md in the same folder:

  • The download page lists every planned file, and says when one is not built.
  • The update check reads one small file, six hours apart at most, and installs nothing.
  • The Rosalena model answers as Rosalena, with its system prompt kept out of the transcript.

What is real on this page, and what is not

The layout is the layout the app draws. The words in the conversation were written by hand. No request leaves your browser when you load this page.

Part of the windowStatus
Left column, top bar, model and effort menu, inspector railReal layout, same measurements and colours as the app
The conversation and the run steps under itWritten by hand and labelled sample. A real answer arrives only when the hosted window opens
Pinned chats, subagent and job counters, account rowFixed examples. They do not update and nothing is running
Sending your own messageIt appears in the log and is answered by a scripted line. No model is called
The hosted window itselfNot online. When it is, it answers on the free cloud models with no account and no key, and it will take the place of this page
