Story

Hi HN — I built CursorLens, a free and open-source screen recorder/editor for product demos and walkthroughs.

It started as a fork of OpenScreen, but I reworked a lot of the capture/editing pipeline for a more native macOS workflow.

Current features:

full-screen or window recording native cursor hide/show behavior on macOS camera overlay + microphone recording timeline editing (trim/crop/zoom/cursor effects/annotations) subtitle generation + rough-cut workflow multi-aspect export (16:9, 9:16, 1:1) and batch export audio export controls (gain, loudness normalization, limiter) It’s still in beta, so stability can vary by machine.

I’d really appreciate feedback on:

recording reliability across setups editing UX (especially rough cut/subtitles) export speed/quality tradeoffs
