Using the workspace

The workspace is the app behind the Open workspace button. This page walks through the parts you will use most.

Chatting

Type in the box at the bottom and press Enter. Shift + Enter adds a new line. You can reverse this under Settings so that Enter adds a line and Ctrl or Cmd + Enter sends.

While a reply is streaming, the send button becomes a stop button. Stopping keeps the text written so far. Pressing Esc does the same.

Under each reply you will find:

• Copy for the whole reply. Code blocks have their own Copy and Download buttons.
• Regenerate to replace the reply, and the arrow next to it to regenerate with a different model.
• Usage: tokens in and out, and a cost estimate when a price is known.

Hover over one of your own messages to edit it. Saving an edit replaces the message and removes everything after it, then asks the model again.

Switching models

The button in the top bar shows the current model and provider. Click it to pick another. The change applies from your next message, and earlier replies keep the label of the model that wrote them.

Comparing models

Click the two-column button next to the message box and choose two to four models. Your next message goes to all of them and the answers appear side by side. Press Continue with this answer on the one you prefer. The conversation then carries on with that answer and that model.

Comparison sends one request per model, so it costs as much as asking each model separately. Tools are not used during a comparison.

Generation settings

The sliders button opens settings for the current conversation: instructions, temperature, top-p, maximum output tokens and reasoning effort. Empty fields are left to the provider. This matters because several current models, including recent Claude models, reject temperature and top-p outright.

Projects

A project is a folder with shared instructions. Create one under Projects, write the background you would otherwise repeat, and start chats from the project. Its instructions are added to every conversation inside it. Move an existing chat with Move to project in the chat menu.

Assistants

An assistant saves a set of instructions, an optional preferred model and default settings. Start a chat from Assistants, or pick one on the empty chat screen.

Finding things

• Pin important chats from the chat menu to keep them at the top.
• Press Ctrl or Cmd + K to open search. It matches conversation titles as you type and searches message text on the server.

Install as an app

In Chrome or Edge, use the install icon in the address bar. On iPhone and iPad, use Share, then Add to Home Screen. The app opens in its own window. It still needs a connection, because every reply comes from your server and your provider.
