How to Use This Tool
Turn four explicit decisions into a reviewable pre-launch brief without AI-generated claims. Generate a deterministic campaign experiment brief from a hypothesis, primary metric, audience and planned duration, entirely in the browser.
The exact task
A campaign test can launch with several creative ideas but no declared primary metric, audience split or review horizon, making the result easy to reinterpret afterward. This page transforms only hypothesis, primary decision metric, audience and allocation, planned duration in days. It does not fetch a remote resource, inspect an account, guess an omitted schema or claim that syntactically tidy output is operationally safe.
Transformation rule
Require four explicit inputs and place them in a fixed hypothesis, metric, audience/allocation, duration and decision-rule structure without generating missing facts. The default fixture is executable, so a future change that alters punctuation, ordering, escaping or validation will fail before publication. Try a small representative sample first and compare every generated token with the source.
How to interpret the output
Add sample-size reasoning, guardrails, exclusions and a stopping rule appropriate to the platform before treating the brief as ready for launch. The supporting outputs—required fields completed, earliest planned review—make the transformation auditable rather than presenting one opaque block to copy.
Assumptions
- One primary decision metric is named.
- Audience allocation is written before launch.
- Duration is a planning commitment, not an automatic significance threshold.
Keep the original text unchanged until the result has been tested in the destination system. Browser processing protects against an upload by this calculator, but it does not make sensitive material appropriate to paste into an untrusted device or extension.
Limitations and safety boundary
It does not calculate statistical power, access campaign data, recommend a hypothesis, prevent interference or determine whether a result is causal. This is a preparation and review tool, not a standards-complete parser, security assessment, legal determination or production deployment system.
Source and verification
The transformation rule was checked against U.S. Small Business Administration — Manage your finances on 2026-08-26. Recheck the destination specification when its grammar can change. All processing here runs in the current browser tab; ecech receives no input through a calculation API.
