Inside Capnot: explanation at the point of action
A recent Product Hunt discovery makes screen meaning visible through overlays, with a documented local speech path and a separate licence-validation service.
Listed on Product Hunt’s 7 November 2026 board. The product page showed #18 and 76 points when checked 8 November; this is a dated discovery signal, not a customer or adoption metric.
Documented components, not a complete production inventory.
- macOS Speech Recognition
- Provider-confirmed API for on-device Live Captions
- macOS Screen Recording permission
- Provider-confirmed permission for local magnification
- Polar.sh API
- Provider-confirmed remote licence-validation service
- Local preferences
- Provider-documented settings and licence-key storage; no independent security test
A recent discovery, not a first-release claim
Capnot appears on the 7 November 2026 Product Hunt archive. The product page showed day rank #18 and 76 points when checked 8 November. Official legal pages are dated March 2026, so this is described as a recent discovery and promotion rather than proof the app was first created in November.
Confirmed product components
Official documentation describes cursor-attached text, a subtitle bar, drawing annotations and pointer focus tools. Live Captions uses macOS Speech Recognition. These published interfaces are confirmed; the app’s complete internal architecture and UI framework are not disclosed by the sources used here. FreeStack has not installed or tested it.
Local speech and remote licensing are different paths
The privacy policy says speech processing stays on the device and magnification uses local screen content with macOS Screen Recording permission. It separately identifies Polar.sh API licence validation and local preference storage. These are provider claims, not a FreeStack security audit. “Local” should not be interpreted as proof that every operation has no network dependency.
A paid tool can still teach a useful design lesson
Official pricing offers a seven-day trial followed by a one-time $12.99 purchase for one Mac. Capnot is excluded from ongoing-free catalogue additions. Its terms describe a proprietary licence and system permissions. Readers should verify compatibility and permission needs before a purchase.
The smaller FreeStack learning route
Editorial lesson: put the explanation where the decision happens, then inspect the finished output without sound. The companion guide uses OBS Studio, GIMP and Kdenlive for one fictional recorded action. That toolkit is a smaller learning route, not Capnot’s production stack. Save it first and consider a paid overlay only when live presentation or repeated setup creates a specific need.
