How it works
From idea to winner in four steps
No scripts. No spreadsheets. Just a clean workflow that turns your thumbnail intuition into measurable wins.
Pick a published video
Search by title or choose from recent uploads. EnhanceTube only lists videos owned by the connected channel.
Add 2–4 variants
Swap the thumbnail, the title, or both. Keep your current live version as the control to compare against.
Set rotation & schedule
Choose how often variants rotate, how long the test runs, and optionally restrict to specific Pacific Time hours.
Launch and watch live
EnhanceTube auto-rotates variants, tracks performance, and surfaces the winner once confidence is reached.
Built for serious creators
Everything you need to test like a pro
The same rigor used by data teams—wrapped in a workflow built for YouTube creators.
Confidence-backed winners
Bayesian estimation tells you when a variant truly wins—no more eyeballing a noisy CTR chart.
Per-variant analytics
Impressions, click-through rate, and watch time tracked separately for every variant you ship.
Fully automatic rotation
Set your interval once. EnhanceTube swaps variants on schedule and logs every change for review.
Pause, stop, or extend anytime
See an early signal? Stop the test and ship the winner. Need more data? Extend the duration with one click.
Full rotation history
Every swap, every metric snapshot, every winner—archived per test so you can learn across experiments.
Safe for your channel
We only rotate the variants you provide. Your video, description, and tags stay exactly as you set them.

Schedule on your terms
Rotate variants on the schedule that fits your audience
Pick a rotation interval that matches your video's traffic pattern. Optionally restrict tests to peak Pacific Time hours so each variant gets a fair shot at the same kind of viewer.
- Rotation intervals from hours to days
- Active-hour windows (Pacific Time) for fair comparisons
- Auto-stop at the duration you choose
Decide with confidence
A real winner—not a hunch
EnhanceTube uses Bayesian estimation to calculate the probability that a variant is actually better. When confidence is high, we surface the winner. When it isn't, we tell you honestly.
- Bayesian probability per variant—not just raw averages
- Configurable confidence threshold to match your risk tolerance
- One-click apply winning thumbnail or title to YouTube

FAQs
Questions, answered
Everything you might want to know before running your first test.
Will an A/B test hurt my video's performance?
No. We only rotate between the variants you provide—the underlying video, description, and tags are never touched. If anything, finding a stronger thumbnail tends to lift performance.
How many variants can I test at once?
You can run between 2 and 4 variants per test. Each variant can change the thumbnail, the title, or both. We recommend keeping one variant as your current live control.
When does EnhanceTube call a winner?
We use Bayesian estimation to track probability that a given variant is the best performer. Once confidence crosses your configured threshold, we surface the winner. If the test ends below threshold, the leading variant is suggested as low-confidence.
Can I run tests on YouTube Shorts?
A/B testing is currently supported for long-form videos. Shorts support is on the roadmap.
What happens to the previous variants?
Everything is archived. You can open any past test and see every rotation, every metric snapshot, and the exact thumbnail/title pair that was live at each point in time.
Do I need a paid plan?
You can get started for free. Concurrent A/B tests are capped per workspace and the limit depends on your plan—see the pricing page for current allowances.
