Screenity is a free open-source Chrome extension that records screen, camera, microphone, and system audio at up to 4K with a basic editor (trim, crop, blur, highlight). There's no transcription, no auto-layouts, no cloud hosting, no analytics, no team features, and no native apps.

Tella records at 4K with AI auto-cut, auto-zoom, auto-layouts, cloud hosting with analytics, embedded players, CTAs, and team collaboration — everything Screenity does locally plus the full video workflow around it.
