From sound to bilingual captions

GlossOne lives in your menu bar with no Dock icon. Three steps from a live voice to readable, translated captions.

Pick a source

Choose your microphone, the audio playing on your Mac, or a specific app such as Zoom or a browser. Then hit start.

Speak or play

GlossOne recognizes speech on-device in real time and detects the language on its own, so there is nothing to configure mid-conversation.

Read both languages

See the original and its translation line by line, in a window or a floating overlay over your meeting, then export the whole session.

Everything in the menu bar

No main window, no Dock icon. GlossOne lives quietly in your menu bar and is one shortcut away.

Microphone or system audio

Transcribe what you say through the microphone, or capture the audio from your Mac or a single app, handy for meetings, videos and calls where you can't reach the speaker.

Live bilingual captions

As people speak, GlossOne transcribes and translates line by line, showing the original and the translation together so you can follow a conversation in two languages at once.

Floating subtitles

Pin captions in an always-on-top overlay over Zoom, Teams, or any video, sized and styled the way you like. They stay readable while you keep working.

On-device by default

Speech is recognized locally with WhisperKit and can be translated on-device too, so your audio never has to leave your Mac, even in a confidential meeting.

Transcribe files too

Drop in an audio or video file and GlossOne transcribes and translates it the same way, then lets you export the result. Great for recordings you already have.

History & export

Every session is saved and searchable. Export a transcript or subtitles as SRT, VTT, TXT or Markdown, ready to drop into a video editor, doc or notes.

Recognition local, translation your choice

Speech recognition runs on-device with WhisperKit. For the translation, keep everything on your Mac with Apple's on-device translator, or pick from 14 engines, each connected directly with your own keys.

Private by design

On-device by default

Recognition runs locally with WhisperKit, and translation can run on Apple's on-device translator. With those, your audio and text are processed on your Mac and never leave it.

No servers, no account

GlossOne has no backend of its own. When you choose a cloud engine, text goes straight from your Mac to that provider, with no relay in between and nothing to sign up for.

Keys in the Keychain

Bring your own keys for cloud engines. API keys, tokens and secrets are stored in the macOS Keychain, never in plain files, never sent anywhere except the engine they belong to.

Sandboxed, no analytics

GlossOne always runs in the App Sandbox and leans on Apple system frameworks. No analytics, no advertising, no third-party tracking. Your transcripts and history stay on your device.
