Join a call
Open Zoom, Meet or anything else that plays through your Mac. Fosfor listens to the other side — the bot never joins and there is no invite link.
Native macOS app for interviews and calls
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.

Ready
Interviewer Question
“Two deadlines land on the same day. How do you decide what goes first?”
I start with whichever one blocks other people. Then I tell both owners early, agree on a new date for the second task, and ship the smaller piece first so nobody waits on me.

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.
Meet Fosfor
One glance tells you what it’s doing.
The orb in the corner of the panel is Fosfor’s face. You never have to read a status line in the middle of a sentence.
Listening
A dim core under the dot grid. Fosfor is following the conversation.
Heard a question
The core lights up and the eyes turn to the panel. A draft is on its way.
Answering
The colour fills the whole sphere while the answer streams in.
Paused
Sleepy eyes, quiet core. Nothing is being heard until you resume.
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. No extra tile, no invite link, nothing for the host to approve.
Always on top
The panel floats above your call window and never steals focus while you are talking.
Українська first
Ukrainian, Russian and English. Pick the language of the call once, and answers come back in it.
Native, not a wrapper
A real Mac app that lives in the menu bar. Show or hide the panel in one keystroke, and resize it however you like.
Private by default
Call audio and transcripts are never saved to your Mac. Close the panel and the conversation is gone.
Who it’s for
For the calls where the next answer counts.
Tell Fosfor who you are in one line during setup. It shapes every answer around you and never makes up facts about you.
Students
Oral exams, thesis defences, internship interviews.
“Explain the difference between a process and a thread.”
Job seekers
Screening calls, HR rounds, technical interviews.
“Why do you want to join our team?”
Career switchers
Calls in a field where the vocabulary is still new.
“How would you measure the success of this feature?”
Already working
Client calls and meetings in a second language.
“Can you walk us through the timeline once more?”
Privacy
Nothing joins your call. Nothing sticks around.
Fosfor is a helper on your side of the screen, not a participant. It hears only what your Mac plays, sends it for speech recognition and the answer, and keeps nothing afterwards.
- No bot, no invite link, no calendar access.
- Your microphone is never used. Fosfor hears the other side only.
- No audio files and no saved transcripts.
- No account, no profile, no keys to paste.
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?
Fosfor listens to your Mac’s system sound, so it works with Zoom, Google Meet in the browser and other call apps that play the other person through your Mac.
Which languages are supported?
Ukrainian, Russian and English. Ukrainian is the default; choose the language of the call during setup or in settings.
What do I need to run it?
A Mac with macOS 13 or newer and an internet connection. On first launch macOS asks for permission to capture system audio; that is the only access Fosfor needs.
Can the other side see the panel if I share my screen?
Fosfor asks macOS to keep the panel out of screen sharing, but some apps capture the whole screen anyway. Before an important call, share a single window instead of the full screen, or keep the panel on a second display.
