Chat
Talk to AI agents, message real people, and go hands-free with voice — all in one conversation.
Chat
One Place to Talk to Anything
CubDen brings AI agents, real people, and your voice into a single chat. Mention an agent, drop into a live voice conversation, fire off a slash command, or message a teammate — all without switching tools.
AI
Chat with Agents
Talk to Cub and any agent you've built or saved from the marketplace. Each agent brings its own persona, tools, and system prompt — switch between them in a single conversation.
Mention agents inline
Type @ to pull any agent into the thread mid-conversation. Autocomplete suggests matching agents as you type.
Browse the agent carousel
Start a new chat by picking from your available agents, each with its own description and capabilities.
Pick your model
Choose which underlying model answers — available models load dynamically so you always see what's live.
Watch responses stream
Replies arrive token by token with a live thinking indicator, so you see Cub working in real time.
People
Chat with Users
CubDen is more than AI. Message other people one on one or spin up group conversations, all in the same interface as your agent chats.
Direct and group messages
Search for users, start a one-on-one thread, or create a group conversation with multiple members.
React with emoji
Tap any message to react. Quick reactions keep group chats lively without adding noise.
Send audio messages
Record and send voice notes that play back inline, right inside the conversation.
Manage participants
View who's in a conversation, add or remove members, and block users when you need to.
Voice
Voice Mode, TTS & STT
Speak instead of type, and let Cub speak back. A full real-time voice loop turns any chat into a hands-free conversation.
Real-time Voice Mode
Hold a live, spoken conversation with an agent. An audio visualizer and live transcript show the dialogue as it happens.
Dictation (speech to text)
Dictate messages instead of typing. Your speech is transcribed straight into the input box.
Read aloud (text to speech)
Play any AI message as audio with a tap. A volume animation shows what's currently speaking.
Choose a voice
Pick from multiple voice personas so Cub sounds the way you want it to.
Commands
Slash Commands
Type / in any AI chat to run commands without leaving the keyboard — manage the conversation, generate images, or wire up integrations on the spot.
Control the conversation
Clear, compact, rename, or start fresh, and regenerate the last response — all from the input box.
Generate images
Run /imagine with a prompt to create images from text without switching tools.
Set up integrations
Connect web search, email, Coinbase, Instacart, and Slack or Teams messaging through guided setup commands.
Content
Attachments & Image Generation
Bring files, images, and AI-generated artwork into the conversation. Everything renders inline so the thread stays readable.
Send images and files
Attach images and documents to a message. Images render inline; audio plays where it lands.
Generate images in chat
Turn a text prompt into an image with /imagine and watch it appear as the generation completes.
Markdown formatting
Messages support markdown — links, tables, and emphasis all render cleanly in the thread.
Organization
Conversation Management
Keep every thread organized and easy to find. Rename, group into projects, search your history, and act on individual messages.
Group chats into projects
Organize related conversations into project workspaces and assign threads as you go.
Search and filter
Find any conversation by name, with unread counts and last-message previews in the list.
Persistent history
Every message is saved with timestamps and tied to your account, so nothing is lost between sessions.
Act on any message
Copy, edit, delete, retry, or rate a response with thumbs up or down — full control over every bubble.
Every reply gets better
Rate AI responses with thumbs up or down and retry anything that misses. Your feedback shapes the conversations that follow.
Requires a CubDen account
Your conversations, voice settings, and history are tied to your account so everything stays private and in sync.
