Made for the live moment

Live should not mean waiting for subtitles.

StreamLingo works beside the content you already watch. No uploads, copy-pasting, or creator integration required.

01

Works across apps

Translate system audio from browsers, streaming apps, podcasts, meetings, and videos.

02

Private by default

Speech recognition and translation run locally. Your audio does not need to leave your Mac.

03

Subtitles that fit

Move the subtitle window and adjust its text size and color while translation is running.

Three simple steps

From spoken audio to your language.

1

Choose your languages

Select what is being spoken and the language you want to read.

2

Start any stream

Play live or recorded content from any app on your Mac.

3

Read along live

Translated subtitles appear in a floating window you control.

On-device by design

Your stream stays your stream.

Everything happens directly on your Mac, so what you watch and hear stays private. After a quick setup, enjoy live subtitles without uploading audio or sharing your conversations.

Set up StreamLingo on your Mac.

Download StreamLingo 0.1.0 beta
1

Open the DMG

Double-click the downloaded StreamLingo-0.1.0-beta.dmg file.

2

Move to Applications

Drag StreamLingo into the Applications folder shown in the window.

3

Confirm the first launch

Why the extra confirmation? Apple has not verified this early version yet, so macOS asks you to approve it manually. Only install StreamLingo from this official download page. Read Apple’s instructions.
