Chat

Chat is your everyday assistant surface: threaded conversations, long-term memory, inspectable tools, and model choice per thread.

What it is for

• Daily questions, drafting, and follow-ups in one place
• Memory retrieval across threads — the assistant can recall what you saved before
• Web search, Gen UI in-thread, and streaming replies you can read aloud
• The same thread spine shared with specialized chat experiences (see below)

Chat experiences (variants today)

Arcadia and Noesis live on separate rail segments for now. They use the same underlying thread model but tune the composer and reply style for different jobs:

• Arcadia — fast, tool-forward answers when you want to move quickly
• Noesis — topic exploration with sparks and suggested replies

We plan to collapse these variants into one Chat surface soon. Until then, treat them as subcategories under Chat — switch from the sidebar rail without losing your thread history.

When to use Chat

Reach for main Chat when you want the full assistant: memory, search, tools, and a general-purpose composer. Use Arcadia or Noesis when the job fits their narrower focus; you can always return here.
