How to use Earwig

A screen-by-screen tour of Earwig: what every control does and how to get subtitles you can actually read. The guide is written for the Mac, with a note wherever iPhone and iPad work differently.

macOS iPhone & iPad notesUpdated 18 September 2026

01Quick start: subtitles in under a minute

Earwig listens to sound, writes down what it hears and translates it, live. There is nothing to import and no file to prepare: you point it at a source of audio, tell it which two languages are involved, and read.

  1. Open Earwig. A single dark subtitle window appears. If this is your first run, a How to Use Earwig card explains the icons; read it and click Continue.
  2. Look at the icon in the bottom-left corner. It shows what Earwig is listening to. Click it and choose System Audio to subtitle whatever your Mac is playing, or pick a microphone to subtitle the room.
  3. Set From to the language being spoken and To to the language you want to read. Click either one to get a list.
  4. Play the video, join the call, or start talking. Text appears as it is recognised, and the translation appears with it.
  5. Drag the bottom-right corner to resize the window, and drag anywhere else to move it. Park it under whatever you are watching.
The Earwig subtitle window: a dark rounded panel with traffic lights, a Trial badge, a settings gear, the ear indicator, and From and To language pickers along the bottom
The subtitle window. Everything lives on this one panel: source at the bottom-left, languages along the bottom, window controls along the top.

02The subtitle window, part by part

Earwig has no ordinary title bar and no main menu to speak of. The whole app is this one floating panel, and its controls fade away when you stop using them so that only the text remains.

Along the top

Close, minimise, zoom
The usual three buttons. The green one snaps the window to fill the screen; click it again to go back. Double-clicking anywhere on the top bar does the same thing.
Trial / Pro
Your current plan. Click it to open the store. If a trial session has run out, an EXPIRED badge appears next to it.
Settings (gear)
Opens the settings window. Keyboard: Command ,
Adjustments (sliders)
A small popover with font size and the four margins, applied to this window only. Handy when one window needs to be bigger than the rest.
New window (plus)
Opens another subtitle window, so you can translate the same audio into a second language at the same time. Keyboard: Command S

Along the bottom

Audio source
The icon on the far left. A microphone means Earwig is listening to a microphone; a computer means it is listening to the Mac's own audio. Click it to switch.
From
The language being spoken. Click for a list of every language your Mac can both recognise and translate.
To
The language you want to read.
Resize handle
The small corner mark on the far right. Drag it to resize; drag anywhere else on the panel to move the window.
The top control bar of the Earwig window: traffic lights, the Trial badge and settings gear on the left, the ear indicator centred, the adjustments and new-window buttons on the right
The top bar, with the ear centred. The ear is both a status light and a button: it animates while Earwig is listening but hearing nothing, and sits still when sound is coming in.

Click the ear to mute Earwig. Muting stops it listening, and it also makes the subtitle text selectable, which is the way to pick out and copy a single line with the mouse. Click it again to carry on listening.

Move the pointer away from the window and, after a moment, the two bars fade out and the panel returns to whatever Transparency you have set. Move back over it, or click it, and they come back. If you would rather they never hid themselves, turn Auto hide controls off in settings.

03Choosing what Earwig listens to

There are two kinds of source: the audio your Mac is playing, and a microphone. The icon in the bottom-left corner tells you which is in use, and clicking it lets you change.

The audio source menu open, showing System Audio at the top followed by the available microphones
System Audio is always the first entry. Below it is every microphone your Mac can see, including USB and Bluetooth ones.

System Audio

Choose System Audio when the sound is coming from your Mac: a video, a conference call, a podcast, a lecture recording. Earwig captures the audio your Mac is playing and ignores its own output, so the subtitles never feed back on themselves.

A microphone

Choose a microphone when the sound is in the room: a person in front of you, a meeting, a talk. Earwig asks for Microphone permission the first time. If you decline, the window tells you and offers the same shortcut into System Settings.

  • Pick the microphone closest to whoever is speaking. Recognition quality follows microphone quality more than anything else.
  • Background music and several people talking at once are the two things that hurt accuracy most.
  • Switching source restarts listening immediately. Any text already on screen stays until new speech replaces it.

04Setting the From and To languages

From is the language being spoken. To is the language you want to read. Both are ordinary lists: click one, pick a language, and Earwig restarts with the new pair.

The From language list open as a popover, showing languages with a checkmark against the current one
Languages are listed by name in whatever language the app is using, with a checkmark against the current one.

The two lists are not the same length. From can only offer languages your Mac can both recognise from speech and translate, while To can offer anything it can translate. That is why a language sometimes appears in one list and not the other.

Earwig does not guess the spoken language for you, so From does need to be right. If the subtitles come out as nonsense words that look vaguely like the right sounds, that is almost always a From set to the wrong language.

The small indicator beside each language

A spinner
The model for that language is being checked or downloaded. Click it to see the progress card.
A red warning triangle
Something went wrong loading that language. Click it to try again.
Nothing at all
Ready. This is the normal state.

05Language packs

The models that do the recognising and the translating are supplied by macOS, not by Earwig, and they download on demand. Settings ▸ GeneralTranslation Languages shows you what is installed.

The Translation Languages window with Translation and Speech recognition sections, each language showing its download state
Two separate lists, because two different things have to be installed: one model to hear a language, another to translate it.

What the two sections mean

Translation
Needed for the language your subtitles are shown in, that is, your To language.
Speech recognition
Needed for the language being spoken, that is, your From language.

What each row can say

Downloaded
Installed and ready to use offline.
Not downloaded
Available, but not on this Mac yet. Use Download.
Downloading…
In progress. Translation packs show a Show progress button that brings back the system's download panel; speech packs can be stopped with Cancel.
Not supported
Your Mac cannot do this language at all, so it will not appear in the pickers.
Failed
The download did not finish. Try again, and check you have a network connection.
The Translation Languages window scrolled to languages that are not installed, each with a Download button, above the footer note and the Open System Settings button
Anything not installed yet shows Not downloaded and a Download button.

Downloads are handled by macOS, which is also why Earwig cannot delete a pack for you. To reclaim the space, use the Open System Settings button at the bottom of the window and remove the language there.

06Reading the subtitles

Speech recognition changes its mind as it goes: it commits to a word, then revises it when the next word makes the sentence clearer. How much of that churn you see on screen is up to you, and it is the single most useful thing to tune in Earwig.

Live Text: how much of the guesswork to show

Settings ▸ SubtitlesLive Text has five settings. They trade immediacy against steadiness.

Live
Every revision appears the moment it happens. The fastest and the twitchiest. This is the default.
Finals Only
Nothing appears until a sentence is finished. Completely steady, but always a beat behind. A pulsing dot shows that speech is being heard.
Committed Words
A word appears once the recogniser has stuck with it three times running. A good middle ground: nearly as quick as Live, with most of the flicker gone.
Slower Updates
Revisions are collected up and drawn on a timer, which you set with Update Interval.
Source Live, Translation Final
The in-progress line is shown dimmed in the original language, and only finished sentences get translated. Useful when you follow the spoken language a little and want the translation as a safety net.

Update Interval only appears when Slower Updates is selected, and runs from half a second to three seconds.

One line, or a transcript

Out of the box Earwig shows only the current line, replacing it as each new sentence finishes. That keeps the window small and the eye in one place, which is what you want when the subtitles are sitting under a video.

The subtitle window with Rolling Text off, showing only the sentence currently being spoken
Rolling Text off, the default. Only the current line is on screen, and each finished sentence replaces the one before it.

Turn Rolling Text on and finished lines stay instead, building up a scrolling transcript you can read back through. That suits a talk or a meeting, where you want to catch up on a sentence you missed.

The subtitle window with Rolling Text on, showing several finished lines above the line currently being spoken
Rolling Text on. Finished lines stay put, and the line being spoken sits at the bottom.

With a transcript on screen, scrolling up pauses the follow-along so the text stops moving under you. A Live button appears in the bottom-right; click it to jump back to the newest line and start following again. Scrolling back down to the bottom does the same thing on its own.

Stopping the text from jumping

As a live line grows it pushes everything above it, which is tiring to read. Pinned Live Text fixes that: it reserves a fixed block at the bottom of the panel for the line in progress, so finished text above it never moves. Pinned Lines sets how tall that block is, from one to four lines.

Showing the original alongside

Turn on Show Original Language and the panel splits in half: the translation on top, what was actually said underneath, with a hairline between them. It costs you half your reading area, so it suits a wide, short window.

The subtitle window split horizontally, translated text above a thin rule and original-language text below
Show Original Language on. Each half gets its own copy button.

Getting the text out

The small copy button in the top-right of each pane puts that pane's whole conversation on the clipboard, history and current line together. With Show Original Language on there are two of them, one per language.

To copy just part of it, click the ear to mute first. Muted text can be selected with the mouse and copied with Command C as normal.

When nothing is being said

After about ten seconds of silence, Earwig writes No Sound in the panel so you know it is still listening and simply has nothing to work with. If you find that distracting, turn off Show silence message; to stop it watching for silence at all, turn off Detect silence.

07Making the subtitles readable

Subtitles are only useful if they are comfortable to read from wherever you are sitting. Earwig gives you a font size, a colour and four margins, and lets you set them per window as well as globally.

Settings ▸ Subtitles

Font Size
8 to 200. The default of 50 suits a window a few hundred pixels tall; go much larger for a window across the room.
Font Color
White by default. A colour picker, so you can match the subtitles to whatever is behind them.
Center Justified
On by default, which reads best for short lines. Turn it off for left-aligned text, which is easier to scan in a tall transcript.
Margin Top / Bottom / Left / Right
Insets as a percentage of the window, 0 to 80. Top and bottom together are capped at 80, as are left and right.
The adjustments popover showing a Size slider under a Font Size heading, and Top, Bottom, Left and Right sliders under Margins
The sliders icon in the top bar opens the same controls for one window only, which is how you make a second window smaller than the first.

08Transparency, corners and staying on top

Earwig is designed to sit over the thing you are watching rather than beside it, and these settings decide how politely it does that.

Settings ▸ General

Transparency
How see-through the panel becomes once the controls have faded. The names run Full, High, Medium, Low, Off, where Full is the most transparent and Off means solid. Hovering the window always makes it solid again so you can read it properly.
Subtitles window always on top
Keeps the panel above other windows, including a full-screen video. Changing this asks to restart the window.
Rounded corners
On by default. Turn it off for square corners, which line up better against the edge of a video.
Auto hide controls
On by default: the top and bottom bars fade out after a few seconds of no interaction. They will not hide while a menu is open or while a language is still loading.
Always show listening ear
Keeps the ear indicator visible even when sound is coming through. Off by default.
Show initialization progress
Shows the model setup card while languages are being checked or fetched. Worth leaving on: it is the only thing that explains a long first start.

09Translating into more than one language at once

The plus button in the top bar opens another subtitle window. Each window has its own From and To, its own font size and its own margins, but they all listen to the same audio.

  1. Click the plus button in the top-right of the window, or press Command S.
  2. Set the new window's To language to the second language you want.
  3. Size and place the two windows side by side, or stack them under the video.
Two Earwig subtitle windows stacked beneath a video, each translating the same audio into a different language
Two windows, one source of audio, two languages. Each keeps its own settings.

This is the quiet trick that makes Earwig good for language learning: put the language you are learning in one window and the one you already know in the other, and read across when you lose the thread.

10Every setting, in order

Open settings with the gear in the top bar or Command ,. The window has five sections, in this order.

The Store section at the top of settings. The price shown is your own App Store region's.

The trial is not a cut-down version: every feature is unlocked, and the only limit is how long a stretch of translation can run. The clock starts at the first translated line, not when you open the app.

Once a trial session reaches the limit, Earwig keeps listening but hides most of each word behind asterisks, and an EXPIRED badge appears next to the plan badge. To lift the limit, click the badge and then Upgrade to Pro.

12iPhone and iPad differences

Earwig is the same app on every device, but a phone is not a floating window, and iOS handles device audio differently. Here is everything that is not the same.

Subtitling the device's own audio
There is no Screen Recording permission on iOS. Instead you start a Broadcast: Control Centre, press and hold Screen Record, choose EarwigTranslator, then Start Broadcasting. Earwig walks you through it on screen.
Using the microphone
While the microphone is live, other apps cannot play audio. That is an iOS rule, not an Earwig one, and it is why subtitling another app needs the Broadcast route.
Several windows
iPad can open more than one subtitle window. iPhone shows a single full-screen view.
Window settings
Transparency, Rounded corners and Subtitles window always on top are Mac-only, since there is no floating window to apply them to.
Narrow screens
Below a certain width the From and To controls stack instead of sitting in a row.

13When something is not working

Most problems come down to one of four things: the wrong source, the wrong From language, a missing model, or a permission that was declined.

No text appears at all

  • Check the ear indicator. If it is struck through, Earwig is muted; click it.
  • Check the source icon in the bottom-left. Listening to a microphone when the sound is coming from a video will get you nothing.
  • If the window is showing a permission message, follow its settings button and grant what it asks for. On a Mac, system audio needs Screen Recording.
  • If it says No Sound, Earwig is listening and hearing silence. Turn the volume up, or move closer to the microphone.
  • Check the volume itself. Earwig hears what your Mac plays, so muted output means no subtitles.

The words are wrong, or look like nonsense

  • Nine times in ten, From is set to the wrong language. Recognition will gamely produce English-shaped words from French audio.
  • Background music and several overlapping voices both hurt badly. There is no fix beyond a cleaner source.
  • A distant or built-in microphone in a large room will struggle. A closer microphone is the single biggest improvement available.

It sits there loading, or offers to try again

  • First use of a language pair needs a download, which macOS handles. Leave it a minute on a slow connection.
  • If it keeps failing, open Settings ▸ Translation Languages and download the pack from there, where you can see exactly which of the two is missing.
  • Downloading a pack needs a network connection. Using one, once installed, does not.

The text is too jumpy to read

  • Set Live Text to Committed Words, which is the best compromise for most people.
  • Turn on Pinned Live Text so finished lines stop being pushed around by the line in progress.
  • Finals Only removes the churn completely, at the cost of always being a sentence behind.

The window is in the way, or will not stay put

  • Turn on Subtitles window always on top to keep it above a full-screen video.
  • Raise Transparency so the panel fades back once you stop hovering over it.
  • Drag the bottom-right corner to resize, and anywhere else on the panel to move. If dragging selects text instead, the app is muted; click the ear.
