# Chat overview

Ethen Chat is the live conversational workspace at `https://chat.upcube.ai`. Sign in, pick a model, and start a conversation — with files, artifacts, tools, memory, and voice sessions where enabled.

## What you get

| Capability | Where | Notes |
|---|---|---|
| Conversations | `/chat` | Streaming chat with history and continuations |
| Model selector | Composer | Switch models per conversation |
| Files | Composer attachments | Uploaded through `/api/attachments/upload` |
| Artifacts | Artifact panel | Durable outputs via `/api/artifacts` |
| Tools | Composer | Tool calls run through the tool runtime |
| Memory | Automatic | Conversation memory store per user |
| Voice sessions | Voice entry point | Realtime speech; see [Voice in Chat](/docs/chat/voice) |
| Deep Research | `/research` | Limited research lane inside Chat |
| Connected Apps | Settings | App connections; see [Connected Apps](/docs/connected-apps/overview) |

## Sign-in and settings

Chat requires sign-in. Account, usage, privacy, sessions, and connected-app settings live under `/settings`. Billing and plan upgrades live under `/upgrade` and `/settings/billing`.

## What Chat is not

- The full Research workspace is a separate, coming product; Chat carries only the limited Deep Research lane.
- The full design builder is coming; Chat carries lightweight design generation.
- Voice in Chat is conversational speech — realtime sessions and transcripts — not a standalone voice product.
