HidaChat

HidaChat is a modern, lightweight, and 100% portable Windows desktop client (.NET 9 / WPF) designed to run multiple WhatsApp Web and Telegram Web accounts simultaneously in organized horizontal tabs. Unlike heavy Electron-based wrappers, HidaChat leverages the native Windows Edge WebView2 runtime and .NET 9 to deliver low memory usage, reduced CPU overhead, and instant tab switching with zero reload delay.

Key Features:

• Multi-Account & Multi-Platform: Run multiple WhatsApp and Telegram accounts concurrently with fully isolated session sandboxes and profiles.
• Instant Startup & Preloading: The active account loads with top priority while background tabs pre-warm transparently, eliminating switching lag.
• Built-In Message Translation: Hover over any incoming or outgoing message to translate it instantly, or translate entire chat threads with a single click.
• 100% Portable (Zero Installation): All session data, settings, and cache remain self-contained inside the local data folder—ideal for USB flash drives.
• Native Notifications & Overlay Popups: Rich interactive toast notifications and visual corner popups with platform badges (WhatsApp / Telegram) that route clicks directly to the source conversation.
• Dark & Light Themes: Automatic synchronization with Windows system theme and custom injected styling for both WhatsApp and Telegram.
• Window Management: Custom borderless window with taskbar-aware maximize (Win32 hook), fluid restore dragging, and corner resize grip.
