OmniGrid

Native multi-view AI workspace — a frameless multi-browser desktop app that shows several AI chat sessions (ChatGPT, Claude, Perplexity, Gemini, local WebUIs, …) side by side in resizable split/grid layouts.

Built with C++20 / Qt 6 (Widgets + QtWebEngineWidgets) and CMake.

Features

• Frameless window with custom titlebar (40 px): app icon, centered workspace title, quick-add + button, layout preset menu, and minimize / maximize / close controls (close turns red on hover, all with animated hover states). Dragging the titlebar moves the window, double-click toggles maximize, all window edges/corners resize with proper cursors.
• Layout engine — nested QSplitter grids: 1×1, 1×2, 2×1, 2×2 and an auto-fit mode; every row/column is freely resizable by dragging the splitter handles (flex ratios are preserved across relayouts).
• View tiles — each tile is a card with a slim 26 px header: favicon + title, back / forward / reload / mute / unload(zZ) / close buttons, and a 1.5 px cyan accent border marking the active tile. Unloading suspends the page (frees CPU) and dims it with an overlay; any navigation wakes it.
• Session & cookie isolation — per tile: Shared (one persistent profile), Isolated (per-tile persistent cookie/cache storage) or Private (in-memory only). Chosen per session from the launcher.
• Workspace persistence — open tiles, their session modes, the layout and splitter ratios are saved on quit (and on every change) to workspace.json. On the next start the same AI sessions are restored, each loading its provider's home page. Isolated profiles keep their storage keys stable, so logins survive restarts.
• Configurable providers — gear button in the titlebar (or Ctrl+,) opens the provider manager: rename/re-point/hide the built-ins and add your own (name, URL, accent color), e.g. local WebUIs. Everything is persisted to providers.json and immediately available in the quick launcher.
• Quick launcher (Ctrl+K) — type to filter all configured AI services (ChatGPT, Claude, Perplexity, Gemini, Grok, DeepSeek, Le Chat, HuggingChat, Copilot, plus your own) or enter any URL; choose target tile and session mode; layout presets included.
• Keyboard-first: Ctrl+1..4 focus tile, Ctrl+T add tile, Ctrl+W close tile, Ctrl+R reload, F11 fullscreen, Ctrl+, provider settings, Ctrl+Q quit.

Build

./build.sh            # configure + build (Release) into build/
./build/omnigrid      # run

Requirements: Qt 6.6+ with qt6-base, qt6-tools, qt6-webengine, qt6-webchannel (on Arch: pacman -S qt6-base qt6-tools qt6-webengine), CMake ≥ 3.21 and a C++20 compiler.

Notes

• Web session data lives under ~/.local/share/OmniGrid/OmniGrid/profiles/ (shared/, isolated-tN/); workspace state in workspace.json, provider configuration in providers.json (same directory). Private sessions never touch the disk.
• A desktop file is provided in packaging/omnigrid.desktop.
• If your desktop environment binds Ctrl+K globally (some KDE setups do), use the + button or Ctrl+T to open the same launcher.
