How to Translate Slack in Real Time: Setup Guide
Slack calls and screen shares often involve speakers from different language backgrounds. Seagull captures your desktop audio and delivers real-time subtitles, letting you follow Slack conversations in your preferred language without interrupting workflow.
What to Look for in a Slack Translation Tool
A good Slack translation tool must capture audio directly from your desktop without requiring plugins, browser extensions, or complex integrations. Look for a solution that detects speech in real-time and displays subtitles in a floating overlay that stays visible above any window, including Slack itself. This means you can read translations without switching tabs or losing focus on the conversation.
Language breadth matters for global teams. You need support for 50+ languages to handle diverse team members, plus the ability to switch languages on the fly if multiple speakers join a call. Low latency is critical, because delays of more than a few seconds make real-time conversations frustrating rather than functional.
Setting Up Seagull for Slack Conversations
Install Seagull on your Mac, Windows, or Linux machine, then launch the app and grant system audio permissions when prompted. Open Slack and join a voice or video call normally, then activate Seagull's translation mode by selecting your target language from the dropdown menu. The floating subtitle overlay will appear immediately and begin translating detected speech as it happens.
If you are having trouble seeing subtitles, confirm that Seagull is running in the foreground and that your system audio is being routed correctly through your speakers or headphones. For better accuracy in noisy calls, position your microphone closer to your monitor or ask other speakers to do the same. If you need to translate both directions in a Slack conversation, switch to Conversation Mode and designate speakers by language so Seagull can alternate translations.
Platform Considerations and Common Pitfalls
Seagull runs natively on Mac, Windows, and Linux, so you are not locked into one ecosystem if your team uses mixed operating systems. However, the person speaking in Slack must have clear audio output from your system, meaning Seagull cannot translate incoming Slack messages or chat text, only spoken audio from calls and screen shares. If your Slack calls go through a third-party VOIP provider, test audio capture before committing to a critical meeting.
Many users forget to enable system audio permissions on first launch, which prevents Seagull from capturing any sound. Double-check your operating system's privacy settings and allow Seagull full microphone or audio input access. Language selection is per-session, so if you switch between calls with different language speakers, change your target language in Seagull's settings each time rather than assuming it carries over from your last meeting.

Frequently Asked Questions
Can Seagull translate Slack messages and chat text?
No. Seagull translates only spoken audio from Slack voice calls, video calls, and screen shares. For text translation within Slack, use Slack's native translation features or a dedicated text translation tool.
Do I need to install a Slack plugin or extension to use Seagull?
No. Seagull captures system audio directly from your desktop, so it works with Slack without any plugins, extensions, or special integrations. Install Seagull once and it works across all your apps.
How do I translate both sides of a Slack conversation?
Switch Seagull to Conversation Mode before your call starts, then assign each speaker a language. Seagull will alternate between translations so you can follow the full exchange.
