Most posts about AI interview copilots avoid naming a number. These do the opposite: list prices, what each tool hides and what it does not, and the cases where Kalfi is the wrong purchase. Kalfi is a macOS overlay at $14/month on your own API key or $19/month hosted.
Final Round AI, ParakeetAI, Cluely, LazyJobSeeker and Kalfi scored on the four criteria that actually decide the purchase: monthly cost, how exposed you are, whether the answer is speakable, and what happens after the job search ends. Includes a section on where Kalfi loses.
Final Round AI lists at roughly $150 a month for a full job-search bundle. If what you need is the in-call overlay, here is the annual arithmetic against $14 BYOK, plus what you give up by leaving the suite behind.
ParakeetAI's list monthly subscription sits around $149.90. We break down what a real month of calls costs on your own OpenAI or OpenRouter key, and when the hosted plan at $19 is the more sensible answer.
A hidden Dock icon covers one of three exposure layers. The screen share, the glance and the process list are separate problems, and a recognizable product name in Activity Monitor is the one nobody else solves.
Job-search copilots have a built-in expiry date. This is how Kalfi's three modes and project threads keep a call assistant useful through client kickoffs, renewals and internal meetings after the offer is signed.
A macOS overlay that catches the question in your call and writes something you can say out loud. $14 a month on your own OpenAI or OpenRouter key, $19 a month hosted. No meeting bot, no Dock icon, and you pick what the app is called.
