About this extension

🌐 Aar318's Live Chat Translator: Real-Time Chat Translation

Translate Twitch, Kick, and YouTube Live chat into your chosen language as messages arrive. The extension works directly inside each site's chat, preserves original message nodes, formatting, and emotes, and keeps the original text available when you need it.

🚀 Getting Started

Install the extension, then refresh an open Twitch, Kick, or YouTube Live page.
Left-click the in-chat globe or extension icon to enable incoming translation.
Right-click either in-chat translation control—or long-press it on touch devices—to choose languages, translation mode, profiles, and filters.
To translate an unsent reply, choose an outbound language and click the compact ⇄ button. Optional automatic outbound translation can handle a draft after typing pauses. The extension never sends the message for you.

✨ New Features (v1.8.0.0)

Per-Channel Profiles: Automatically restore inbound language, outbound language, translation mode, automatic-outbound preference, and filters when returning to a Twitch, Kick, or YouTube Live channel.
Automatic Outbound Typing: An optional default-off mode translates an unsent draft after typing pauses, immediately handles a draft already present when enabled, and cancels stale work when the text changes.
Clear Outbound State: The outbound icon turns green while automatic translation is active; left-click pauses it and clears the setting, while a second click resumes it and handles the current draft.
Message Filters: Skip bots, commands, link-only or emote-only messages, repeated spam, selected users, and messages outside configurable lengths.
Translation Health: Settings show queued work, translating, temporary throttling, bounded retries, disabled state, and errors without adding another toolbar control.
Expanded Language Menu: Common choices appear first, with dozens of additional supported languages under a clean expandable section.
Cleaner Responsive Settings: Rebuilt menus use consistent typography, grouped sections, viewport-safe placement, and focused tooltips for non-obvious controls.
Stronger Long-Session Reliability: Bounded caches, queues, fragments, and spam fingerprints prevent memory growth, while editor-specific safeguards prevent duplicated or layered draft text.

⭐ Key Features

Real-Time Translation: Translates visible chat history and newly arriving Twitch, Kick, and YouTube Live messages through Google Translate's public endpoint.
Automatic, Click, and Hover Modes: Choose continuous translation, translate only clicked messages, or temporarily translate messages while hovering.
Broad Language Support: Twelve common target languages remain immediately visible, with dozens of additional Google Translate languages under More languages.
Per-Channel Profiles: Restore languages, mode, automatic outbound behavior, and filters independently for each channel.
Outbound Draft Translation: Translate an unsent reply independently from incoming chat—even when incoming translation is disabled—using a fixed language or the most recently detected incoming source language.
Optional Automatic Outbound Translation: Waits for a typing pause, cancels stale drafts, and safely replaces only the draft that still matches the queued text.
Message Filtering: Optionally skip bots, commands, links, emote-only messages, repeats, selected users, or messages outside chosen length limits.
Translation Health and Retries: View Ready, Queued, Translating, Throttled, Disabled, or Error state; temporary provider failures use bounded retries.
Original Text Preserved: Translations retain original message nodes, emotes, spacing, and formatting; translated text can be restored or inspected through its original-text tooltip.
Translate Selected Text: Select text on a supported page, right-click it, and choose Translate selected text for a compact original/translation result.
Easy Controls: Left-click toggles incoming translation; right-click or mobile long-press on either control opens its language and settings menu.
Safe Draft Replacement: Twitch Slate, Kick Lexical, and YouTube Polymer editors use platform-specific, reconciliation-aware replacement paths that never activate Send.
Mobile-Friendly Menus: Touch gestures use stable long-press handling, scrollable choices, viewport clamping, and safe placement around native mobile overlays.
Optional Page Controls: Hide or restore injected controls from the extension menu. Controls stay out of the way during fullscreen and supported native overlays.
Efficient Processing: Skips very short messages, batches requests, caps translation caches and queues, and protects against stale results after settings changes.
Navigation Resilience: Reconnects observers and controls after Twitch, Kick, or YouTube replaces chat containers or navigates without a full reload.

🔐 Permissions & Privacy

Storage: Saves inbound/outbound language choices, automatic-outbound preference, translation mode, channel profiles, filters, last detected incoming language, and injected-button visibility.
Context Menus: Adds extension-icon controls and the user-invoked Translate selected text command.
Host Permissions: Runs only on supported Twitch, Kick, and YouTube pages and allows requests to translate.googleapis.com.
Translation Data: Only eligible chat text or explicitly selected text, together with the target-language code, is sent to Google Translate. Requests omit browser credentials.
Local Data: Chat messages, selected text, translations, and usernames are not written to browser storage. Translation caches exist only in memory for the page session.
No Tracking: No analytics, advertising tracking, or streaming-platform account is required.

ℹ Notes

Incoming translation starts disabled and runs only when the user enables it.
Automatic outbound translation is off by default. Outbound translation replaces an unsent draft but never sends a chat message automatically.
