Product Copy A/B Test Planning Agent
A test plan with a testable hypothesis, enough traffic and no conflicts, and an honest readout
What it does
Copy tests often run with a weak hypothesis, too little traffic or a clash with another test. This agent reads the goal, the page traffic and the current tests. It writes a clear hypothesis, calculates the sample size and run time needed, and flags conflicts with other experiments. It proposes variants that differ on one idea. After the test reads out, it checks the result against the hypothesis and the sample size reached. The writer and product manager approve the test. Edge case: the page gets 800 visits a week, so the agent says a small lift cannot be detected and suggests a bigger change or a longer run.
How it works
Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.
Read the steps as a list
- Copy change proposed
- Read the goal metric, baseline and traffic
- Write a hypothesis with the expected change
- Calculate required sample size and duration
- Can the test reach the sample size within the allowed duration?If not: propose a bigger change, a broader audience or a longer run. Back to step 3.
- Check the test calendar for conflicts
- Does the test overlap another test on the same page or metric?If not: propose a new schedule or segment. Back to step 5.
- Draft variants with one idea each
- Writer and product manager approve the testThe agent waits here for your OK.
- Read the results after the test ends and compare them to the hypothesis
- Test plan and readout
How it decides
A test runs only when expected traffic can detect the minimum lift in a reasonable time and no other test affects the same metric.
- Plan for a minimum detectable lift stated up front
- Limit duration to 4 weeks
- Avoid overlapping tests on the same metric
- Change one idea per variant
Make it yours
Every agent is a starting point. You choose these settings for your own situation.
- Minimum detectable lift
- Maximum duration (default 4 weeks)
- Confidence level
- Pages and metrics covered
What keeps you in control
It always asks you first
- Launching the test
- Decision to ship a variant
Hard limits
- Never starts a test
- Never calls a winner before the planned sample
It stops when
- Done: test planned and read out
- Stop: traffic cannot support any test
