Version Lab
Stop filming the version you happened to write last.
Paste the hooks, openings, CTAs, or scripts you are torn between and Retensis compares them directly: which one is predicted to hold attention best, how well each fits your style, and what the strongest version is doing that the others are not. You get a reason, not just a ranking, so the lesson carries into the next video instead of ending with this one.

The Real Decision
Choosing between your own versions is the hardest call.
By the time you have written three hooks you have lost the ability to judge any of them. You know what comes next, you remember why you wrote each one, and you like the one you finished most recently. Version Lab reads each version without any of that history and compares them on what a first-time viewer would actually hear.
Choosing between your own versions is the hardest call.
Ranked With Reasons
A ranking you can argue with, because it shows its work.
Each version is scored and placed, and every placement comes with the reason behind it. That matters more than the order, because the reason is the part you can reuse.
- Which version is predicted to hold attention best, and why
- A predicted-retention score for each version
- How well each fits your Creative DNA, when you have one
- What the strongest version does that the others do not
Strong performance
Improve hook and audio for an A.
One Change at a Time
Learn something the comparison can actually teach.
If two versions differ in six ways, a winner tells you nothing. Version Lab is most useful when versions differ in one deliberate way: a different hook, a tighter open, a different first line. Then the result is a lesson rather than a coin toss, and it applies to every video after this one.
Opening 3 seconds lack a pattern interrupt.
Current hook
“So here's my morning routine…”
Suggested hook
“Stop waking up tired. This changed everything.”
Before, Not After
Decide before you film, not after it underperforms.
Publishing to find out is the slowest and most expensive test there is, and the platform only shows you the result once. Comparing first means the version you film is the one predicted to hold attention best, and the versions that lost still taught you something. To compare two finished edits, use Before and After.

FAQ
Common questions
Two to five versions of the same element: a hook, an opening, a call to action, or a full script. Comparisons are clearest when the versions differ in one deliberate way, because then the result tells you which change worked rather than which bundle of changes happened to land.
Not in Version Lab. It compares written versions before you film. To compare two finished edits, analyze both and put them side by side in Before and After, which shows the score changes and what measurably changed in the edit.
Version Lab works before there is a video. It reads your written versions against each other and answers the question you actually have, which is which one to film and what the winner is doing differently.
Version Lab is part of Growth, alongside the rest of the Create Studio.
