It arms itself
Open Zoom and Plainly is already listening. No bot joins the meeting and no one else sees it.

Plainly puts live captions on top of your call and, underneath every sentence, the same thing said plainly — or in your language. It turns itself on when a call starts and disappears when it ends.
Two lines.Always.
A native speaker on a client call talks fast and idiomatically, and if you are listening in a second language you lose the thread — not because the words are hard, but because the idioms are. Asking them to repeat it costs you the room. Plainly listens to the call audio, shows what was said, and directly under it a plain-English rewrite of the same sentence, so you recover the meaning without ever leaving the call.
How it works
01
Open Zoom and Plainly is already listening. No bot joins the meeting and no one else sees it.
02
What they said, and underneath it the plain version. Idioms get a dotted underline you can tap for the meaning.
03
Pinned phrases go to a list you can review after the call. Everything else is gone when you hang up.
Three placements
Placement 01
The primary direction. The live line is boosted in size and given the accent rule; older lines fade back. Scrolling up detaches from live and reveals a “jump to live” pill.
Keeps two lines of history. Covers a corner of the video grid.
Placement 02
One line, minimal footprint. Covers no faces and carries the largest type of the three, so it is the one to use when the call is the whole screen.
Trade-off: no history at all — catching up means opening the panel.
Placement 03
Docked, for reading along. Best for long calls where you want to scan back over what was said earlier.
Trade-off: costs horizontal space, so the video grid shrinks.
What you get
What they said, and underneath it the same thing said plainly.
Tap the dotted underline for what it actually means
Plain English, Spanish, Korean or Portuguese — switched mid-call.
Keep only what you pin. Everything else is gone when you hang up.
The second line
The bottom line defaults to plain English. The same slot can hold any language you read faster than you listen — switch it mid-call from the menu bar.
Privacy
Audio is transcribed in the moment and discarded. There is no file to leak.
Nothing joins the call and no participant list shows an extra name.
The overlay is drawn on your screen only — it does not appear in a shared screen.
Pinned phrases stay on your machine unless you export them yourself.

All downloads
Plainly is not yet signed with an Apple Developer certificate, so macOS shows “Apple could not verify Plainly is free of malware.” That is Gatekeeper doing its job on any unsigned app, not a problem with the download.
On macOS 15 and later, right-click → Open no longer works. Apple removed that bypass; System Settings is the only route.
Prefer the Terminal? This clears the quarantine flag on the app so it opens straight away:
