Hear the question. See the answer.
Fosfor listens to the other side of your call and puts a ready answer in a floating panel on your screen — in about a second. No bot joins the meeting.

How it works
Three things. That’s the whole app.
No setup calls, no browser tabs, no plugins to install in your meeting.
Read the answer
The question appears as a transcript, and a usable draft follows in about a second — short, structured, the way you would actually say it.
Say it in your words
Skim the panel, pick the parts you like, keep your eyes on the camera. Close it when the call ends.
Features
Built for the silence before you answer.
Small app, few opinions, nothing to manage during a call.
Around one second
The draft is on screen before the pause gets awkward. Streaming text, not a spinner.
No bot in the room
Nothing joins the participant list. Participants never see a “Fosfor” tile or a recording notice.
Always on top
The panel floats above your call window and never steals focus while you are talking.
UA · RU · EN, mixed
Switch language mid-sentence if the call does. Answers come back in the language of the question.
Native, not a wrapper
Written for macOS, runs on Apple Silicon and Intel, about 40 MB on disk and light on battery.
Private by default
No meeting recording is written to disk, and you can wipe the session history with one click.
Privacy
Nothing joins your call. Nothing sticks around.
Fosfor is a helper on your side of the screen, not a participant. It is designed to leave no trace in the meeting and as little as possible on your Mac.
- No bot, no invite link, no calendar access.
- Meetings are never recorded or stored as audio files.
- Transcripts stay for the session — clear them whenever you like.
- Sign in once; no profile, feed or notifications.
FAQ
Fair questions.
Does a bot join my Zoom or Google Meet?
No. Fosfor runs as a local macOS app and listens to the audio your Mac is already playing. There is no participant, no invite and no meeting link shared with anyone.
Which apps does it work with?
Anything that plays the other person’s voice through your Mac: Zoom, Google Meet, Microsoft Teams, Discord, Webex, Slack huddles and plain phone calls over the browser.
Which languages are supported?
Ukrainian, Russian and English today. You can switch mid-call, and the answer follows the language the question was asked in.
What do I need to run it?
macOS 13 or newer on Apple Silicon or Intel, about 40 MB of disk space, and headphones so the app hears the call and not the room.
How much does it cost?
Fosfor is free while it is in beta. Download it, use it in your next call, and tell us what felt wrong.
