Frequently asked questions
Does Braiv run live A/B tests on YouTube?
No. Braiv scores and compares thumbnail candidates before you publish, and generates replacements for videos already live. Live split-tests that rotate covers on YouTube are a different product category; Braiv is the pre-publish analyser and the back-catalogue replacement workflow.
What does thumbnail CTR scoring actually measure?
Braiv scores composition, contrast, text legibility at feed size, and how well the image matches the title. The result is pre-publish feedback you can act on — not a guarantee of a specific click-through rate once the video is live.
Can I test thumbnails on videos already published?
Yes. Connect a channel, identify covers that underperform, generate stronger candidates from the video frames and transcript, score them, and push the replacement. That is the A/B angle Braiv supports: decide, then replace.
How many scored thumbnails can I generate a month?
Business includes 5,400 AI credits a month covering 270 thumbnail generations, unlimited connected channels, and rollover to 16,200. Pro covers 135 generations and 10 channels; Starter covers 30 and 3. On Demand includes 10 thumbnail generations. Regional pricing is applied automatically.
