Threadline

Welcome to Threadline

Threadline is a secure, modern web-based messaging platform. Here's how to use its features:

Access & Profile

• Passcode: Your access is guarded by a local passcode. This protects your device session.
• Unique Code: Share your uppercase Unique Search Code (e.g., ALEX99) with others so they can message you.
• Profile: Update your Display Name, Avatar, and Code anytime via the top-left profile button.

Messaging & Media

• Chats: Use the Global Chat for public discussion, or search codes for 1-to-1 private messaging.
• Groups: Click the New Group icon to create a custom room with multiple members.
• Attachments: Click the paperclip to send images. All media is client-side encrypted before upload.
• Voice Notes: Hold the microphone icon to record. You can play back at 1x, 1.5x, or 2x speed.
• Reactions: Right-click or long-press a message to add an emoji reaction.
• Forwarding: Right-click or long-press a message to forward it to another chat.

Privacy & Security

• Disappearing Messages: Use the top-right menu in a chat to set messages to auto-expire.
• Encryption: Message content is encrypted in the browser using CryptoJS before being sent to Firebase.
• Limitations: Passcodes are local application gates. API keys for AI and encryption shared secrets are present in browser memory. This is not a replacement for Signal-grade E2EE.

AI Assistant

• Click the Robot icon to open your personal persistent AI chat.
• Powered by Gemini/Groq (depending on configuration).
