Seagull vs DeepL: Which Translation Tool Should You Use in 2026?

You've probably heard of DeepL. It's excellent. If you need to translate a paragraph of text, a PDF, or an email, DeepL is one of the best tools in the world for that job.

But if you've ever been on a Zoom call in Japanese, listened to a Korean podcast, or tried to follow a YouTube lecture in Spanish, you know that copying and pasting text into a translator doesn't cut it. The audio keeps going. You can't pause a live meeting. And even if you could, the workflow of transcribing, pasting, translating, and reading is painfully slow.

That's where Seagull comes in.

Seagull and DeepL are not really competitors. They solve fundamentally different problems. DeepL translates text. Seagull translates live audio. This post breaks down exactly where each tool shines so you can pick the right one (or use both).

DeepL at a Glance

DeepL launched in 2017 and quickly earned a reputation for producing translations that sound natural and fluid. For many language pairs, it consistently outperforms Google Translate in quality, especially for European languages.

Here's what DeepL does well:

• Text translation: Paste in text and get a high-quality translation. The core product is simple and effective.
• Document translation: Upload PDFs, Word files, and PowerPoint presentations. DeepL translates them while preserving formatting.
• Browser extension: Highlight text on any web page and translate it inline.
• API access: Developers can integrate DeepL's translation engine into their own products.
• Write feature: DeepL Write helps improve and rephrase text, even within the same language.

For professionals who work with written content, translators, writers, and international teams exchanging documents, DeepL is the gold standard. It deserves its reputation.

Seagull at a Glance

Seagull is a desktop app that translates audio in real time. It captures any audio playing on your computer and displays translated subtitles as a floating overlay on your screen.

Here's what makes Seagull different:

• System-level audio capture: Seagull listens to your computer's audio output directly. No browser extensions, no plugins, no copy-pasting. If you can hear it, Seagull can translate it.
• Floating subtitle overlay: Translations appear as always-on-top subtitles that sit over whatever app you're using. Watch a YouTube video, join a Zoom call, or listen to a podcast, and the subtitles just appear.
• Conversation Mode: Set your phone or laptop between two (or more) people speaking different languages. Seagull detects who's speaking, identifies the language, and shows each person the translation in real time. It supports up to 4 languages simultaneously.
• 60+ languages: Including Japanese, Korean, Chinese, Arabic, Hindi, Swahili, Tagalog, and many more.
• Works everywhere: Zoom, Google Meet, Teams, YouTube, Netflix, Spotify podcasts, games, lectures. Anything with audio.
• Mac, Windows, and Linux.

Feature Comparison

When to Use DeepL

Let's be straightforward. If your primary need is translating written content, DeepL is the better tool. Here's when it's the right choice:

• Translating documents: You have a contract in German, a research paper in French, or a slide deck in Portuguese. DeepL handles these beautifully and preserves the formatting.
• Emails and written communication: You're drafting an email to a colleague in another language, or you've received one you need to understand. DeepL's text translation is fast and accurate.
• Professional translation work: If you're a translator or localization professional, DeepL's quality and API make it a core tool in your workflow.
• Browsing foreign-language websites: The browser extension lets you translate text inline without leaving the page.
• Improving your writing: DeepL Write can help you rephrase and polish text, even if you're not translating between languages.

For text, DeepL's translation quality is arguably the best in the industry. If that's your use case, use DeepL. We mean it.

When to Use Seagull

Seagull wins when the content you need translated is audio. If someone is speaking and you need to understand them in real time, that's Seagull's job.

• Meetings and calls: You're on a Zoom call with teammates in Tokyo, a Google Meet with a client in Seoul, or a Teams standup with colleagues in Berlin. Seagull captures the audio and shows you translated subtitles as they speak.
• YouTube and online lectures: Watching a coding tutorial in Russian? A history lecture in Mandarin? Seagull gives you live subtitles in your language, overlaid right on the video.
• Podcasts and interviews: Listening to a podcast in Spanish or a recorded interview in Arabic? Seagull translates as you listen.
• Movies and streaming: Foreign films on Netflix, anime without subtitles, live streams on Twitch. Seagull works with all of them because it captures system audio directly.
• Gaming: Playing with teammates who speak a different language? Seagull can translate voice chat in real time.
• Face-to-face conversations: Traveling abroad, visiting a doctor who speaks a different language, or chatting with your partner's family. Conversation Mode turns Seagull into a live interpreter for up to 4 languages at once.

None of these use cases are possible with a text translator. You can't paste audio into DeepL. That's the gap Seagull fills.

Can You Use Both?

Absolutely. And many people do.

The two tools complement each other perfectly. Use DeepL when you're working with written text: documents, emails, web pages, and anything you can copy and paste. Use Seagull when the content is audio: meetings, calls, videos, podcasts, and live conversations.

If you're a language learner, having both is especially powerful. Use Seagull to watch content in your target language with real-time subtitles. Use DeepL to look up specific phrases or translate reading materials. They cover different parts of the learning experience.

If you work on a multilingual team, the combination is even more useful. DeepL handles your async communication (documents and messages). Seagull handles your sync communication (meetings and calls).

The Bottom Line

DeepL is the best text translator available. Seagull is a real-time audio translator. They solve different problems, and comparing them head-to-head isn't really fair to either tool.

If you need to translate a document, use DeepL. If you need to understand someone speaking in another language right now, use Seagull.

If you haven't tried Seagull yet, you can download it for free and get 1 hour of translation to test it out. It works on Mac, Windows, and Linux.
