A/B Title Test Exporter
Open YouTube Studio → Content for each channel you want to export — one tab each — then come back here. Each scan runs in that channel's own tab, so it always uses the account you are already signed in as.
Multiple channels are scanned one after another, each saving its own CSV. They are never run in parallel: the request rate is what makes YouTube start throttling.
Everything comes from YouTube's own endpoints — titles, full descriptions, release dates, impressions, CTR, engagement, and each A/B test's variants, watch-time shares and winner. No video pages are opened, so a whole channel takes seconds.
The CSV saves itself to Downloads when a scan finishes, so you can start it and walk away. Results are kept on disk until the next scan — download or note them before scanning a second channel.
