It runs in any modern browser—Chrome, Safari, Edge, Firefox, Brave, Opera, Arc—and records the four tracks you actually need, in full quality and perfectly synced:

🎤 Mic (your voice)
📷 Camera (your face)
🖥️ Screen (what you’re reacting to)
🔊 System audio (the YouTube/TikTok/stream audio)

All four are captured locally and auto-synced, so brief Wi-Fi hiccups don’t ruin a take—and your exports stay clean.

Why browser-based is better

Downloading software is slow and heavy. Installs, updates, drivers, and complex setups waste time and bog down your computer. A browser workflow is fast, lightweight, and consistent across Mac, Windows, and Chromebook—no learning curve, just open a tab and record in high quality. Local capture also means your internet connection doesn’t dictate quality.

Why do most browser recorders miss the sound (system audio) coming from a YouTube video?

Tools like Canva, Riverside, Descript, Loom often capture your mic and webcam but skip system audio. Browsers lock this down for privacy, and keeping mic + camera + screen + system audio in sync is harder than it looks—so most products avoid it. Podsplice solved that puzzle without clunky workarounds.
