Our take

Connecting Captions delivers a privacy‑centric, low‑latency captioning solution that excels in controlled environments like meetings and presentations. Its on‑device architecture is a strong selling point, though the macOS‑only scope and limited language support beyond 25 languages may restrict broader adoption. Overall, it’s a solid tool for privacy‑conscious users who need reliable live captions on a Mac.
