macOS overlay · $14 BYOK

The answer is on screen before the pause gets awkward.

Kalfi listens to your call from your own Mac, catches the question, and writes one line you can actually say out loud. BYOK is $14/mo with your OpenAI or OpenRouter key — or $19 if we host the models. Final Round lists around $150.

Length
Tone
01

Load the context once

Pick Interview, Client, or Chat. Fill only what that mode needs — JD and resume, project scope, or a chat topic. Length, tone, and meeting language stick to the session so you are not re-typing before every call.

  • Three modes, separate forms
  • Key stays in encrypted storage
  • Reuse the same thread next week
02

Listen the way the call runs

Mix system audio from Meet/Zoom with your mic, or pick one. The overlay floats above fullscreen so you never leave the call to “check the AI.”

  • System + mic mixing
  • Floats over fullscreen apps
  • Ask / Mic Ask when detection misses
03

Say one speakable line

Not a transcript dump. Kalfi writes a line you can actually say out loud — short enough for the pause, tuned to the tone you set, grounded in the session context.

  • Brief / balanced / detailed
  • Formal / neutral / casual
  • Force-answer any transcript line
04

Close the meeting properly

Generate a summary, browse history without hijacking the live session, then start the next meeting inside the same project thread — so meeting two already knows what you promised in meeting one.

  • Per-meeting summaries
  • Browse-only history
  • Thread continuity across calls
Stealth

Flip the switch and watch it leave the shared screen.

Same Google Meet call, same Kalfi overlay you actually run. Content protection keeps the panel off the shared screen — toggle stealth off to see what you would leak without it.

Honest caveat: screen-capture protection depends on the OS and the conferencing app. Test your exact setup before you rely on it, and follow the rules of the room you are in.

Personal stealth

Make it look like Notes — not like an AI copilot.

Competitors hide the dock icon and still appear in Activity Monitor under brand names like Cluely, Final Round, or Parakeet. Kalfi lets you set your own display name and logo, so the overlay and process title look like a boring Mac utility you chose — not a known AI brand.

  • Custom name in the overlay header
  • Your logo instead of the default mark
  • No Dock / Cmd+Tab icon on macOS
  • Panel window + content protection for share

Set this in desktop Settings → Stealth branding after install. Where macOS exposes the process title, Kalfi follows your name. Binary packaging still ships as Kalfi for updates — the point is what a glancing human sees on screen and in the process list.

Real monthly cost

Do the maths before you sign a $150 subscription.

Final Round markets around $150/mo for live help. Kalfi BYOK is $14 plus your own model spend — or $19 flat if we host the models. Move the sliders.

Questions

The things people ask before downloading.

Mac says “Kalfi is damaged and can’t be opened” — is my download broken?

No. That message is Apple’s Gatekeeper blocking an app that is not Apple-notarized yet. The file is fine. Follow Docs → Install → macOS: try System Settings → Privacy & Security → Open Anyway, or Control-click → Open. Only if those fail, use the one-line Terminal fix (xattr -cr /Applications/Kalfi.app).

How do I install and use Kalfi for the first time?

See the full guide in Documentation — install, first-time setup, and daily use. On Mac prefer kalfi-…-mac.dmg.

Does my API key ever touch your server?

No. On BYOK the key lives in encrypted storage on your machine and talks straight to OpenAI or OpenRouter. Our API only appears when you choose Hosted / Pro, and then the provider key is ours, not yours.

What actually runs where?

The app runs on your computer — audio capture, transcript, session history, all local. This page is static hosting. The Pro backend runs on a small VPS and only handles login, subscription state and the model proxy.

Is this allowed in my interview or meeting?

That depends on the room. Kalfi is built for calls where assistance is permitted — client work, internal meetings, sales, practice, language support. If an employer, school or client says no, respect it.

Which providers and models work?

Anything OpenAI-compatible: OpenAI directly, OpenRouter for model choice, or a custom base URL for your own gateway. Chat and transcription models are configurable per install.

Windows and Linux builds?

Yes. macOS, Windows, and Linux installers ship from the latest GitHub Release. The homepage download button detects your OS and downloads the matching file directly. See Docs → Install for SmartScreen and AppImage notes.

Install it, paste a key, join your next call.

One button detects your OS. Use the chevron to switch Mac, Windows, or Linux. On Mac, if you see “damaged”, follow Docs → Install (Open Anyway).
