LogCastle for PalaceChat

Features

What LogCastle can do

Modern chat interface

Discord-style message cards with color-coded avatar bubbles, grouped consecutive messages, and inline timestamps for Chat, Whispers, and Admin.

Dual log view

Monitor two rooms or users side-by-side without switching tabs. Each pane scrolls independently with its own complete history.

Themes & color config

Full light and dark mode with OS sync, accent color swatch pickers, per-message-type color settings, gradient, glow, background image, and rainbow effects.

Real-time translation

Translate incoming chat messages on the fly via Microsoft AI Translation into 50+ languages — scoped to what’s actually used in PalaceChat.

Emoticons & GIFs

Discord-style docked emote panel with category tabs, full GIF playback via XamlAnimatedGif, and integrated Tenor search by keyword.

ChatGPT assistant

Type chatgpt: your question inline to get answers from GPT 4.1 mini right inside the log — no context switching needed.

Media cards

Image and GIF links render as inline expandable cards. Embedded AV player for Discord mp3, mp4, OGG, and WebM links with playback controls.

Admin tools

IP and geolocation lookup for active users in a dedicated Admin tab, backed by a fast two-tier SQLite and memory cache.

Smart notifications

Keyword notification cards with optional sounds, taskbar flashing for new whispers, and a “new messages” scroll banner when not tailed to the bottom.

Scrollable server tabs

Tab strip scrolls left and right with arrow controls. Tabs with new activity light up their chevron in your current accent color.

Full log history

Separate tabs for Chat, Whispers, Admin, and Pages — each with its own complete scrollable history per session and server connection.

Font & display options

Per-tab font family, size, and weight via a Material Design font dialog. CTRL + scroll wheel resizes font per-tab without affecting others.
