What's Inside

Everything you loved,
nothing you didn't.

Circul is a built natively, per platform. — No Electron. No Chromium.

💬
Direct Messages
One-on-one conversations with glossy chat bubbles, read receipts, pinned messages, and full message history search.
👥
Group Chats
Create named groups, invite friends, rename at any time. Unread badges keep you on top of every thread.
🏛️
Panels & Channels
Familiar community spaces with named channels, categories, invite codes, and public/private visibility.
🟢
Live Presence
Online, Away, Busy, Offline — with a mood line under your name. Status updates propagate instantly over WebSocket.
🤝
Friend Requests
Send, accept, or deny friend requests the old-fashioned way. Your contacts list is curated, not algorithmic.
🖼️
Images & Avatars
Send inline images in any chat. Set a custom avatar and even a personal chat background that friends see when messaging you.
📌
Pinned Messages
Pin any message in a conversation or channel so important info never gets scrolled away. Unpin anytime.
✏️
Text Formatting
Bold, italic, underline — plus @mentions that notify the right people in group and channel messages.
🔄
Auto-Update
Always enjoy the latest features, without worrying about app updates.
Authentic Sound Design

You'll recognise
every single one.

Familiar and nostalgic sounds. You'll remember each one of them. Each action has its own sound.
