On price, the gap is real. Cluely's paid plan sits in the $20 per month range for the basic tier and climbs higher for the premium one. Whisply Pro is $19.99 monthly or $11.99 on annual billing, with models included, so there is no separate OpenAI or Anthropic bill on top. The Free tier is enough for most students and individual contributors to get real work done without paying anything.
On privacy, Whisply ships with system-level content protection on by default. The overlay window is excluded from screen recording APIs, which means it does not appear when you share your screen on Zoom, Google Meet, Teams, Slack huddles, Discord, or in a QuickTime recording. Cluely has had public incidents where the overlay surfaced on shared screens. That is the kind of thing that matters more the higher the stakes of your call.
On scope, Cluely is a meeting assistant first. Whisply is an overlay first. That sounds like a small difference and it changes everything. The overlay model means Whisply is just as useful while you are reading a contract, debugging a stack trace, drafting an email, or sitting in a live exam, as it is during a call. It does not need a meeting to justify itself.
