From hypothesis to implementation
Move the approved brief into implementation.
For recurring client tests: keep the brief, page context, revisions, and editable code together in Chrome.
02
Describe the change
Describe the layout change and what must stay intact: approved copy, offers, CTA behavior, and tracking. Add a visual reference if useful.
03
Preview and refine
The copilot inspects the page and proposes code. Review the preview, then ask for a revision or edit the code yourself.
04
Review and own the code
Inspect and copy the JavaScript and CSS. A qualified implementer reviews and tests the code in your experimentation platform.
Live-page preview
Turn product facts into reasons to buy.
The test idea: make product quality easier to judge at the buying decision. Supply your approved USP list. VibeVariant turns it into benefit-led copy and a responsive block with icons beneath the purchase button. Compare the control, refine the design, and review the code.

A tighter experiment loop
Build for the page. Refine for the brief.
For the layout changes and revisions that take more than a quick visual-editor tweak. Use live-page context and keep control of the code.
Work from the real page, not an abstract prompt.
Select the client’s actual section. The copilot can inspect its DOM, styles, and layout, so you can work from the existing site instead of rebuilding page context in a separate prompt.
Keep revisions with the variant.
Move from the approved brief to a browser preview. Ask for changes in the same conversation and refine the implementation as you review.
A preview you can inspect.
Checks apply to the page attached to your conversation. Review responsive layouts, dynamic states, and behavior in your testing platform before launch.
Inspect, edit, save, and copy every line.
Inspect, adjust, and copy the JavaScript and CSS. Keep your existing deployment and measurement workflow, with a qualified reviewer owning the handoff.
Target a page, a URL family, or a full journey.
Use exact, simple, or starts-with rules, plus named aliases for variants that span several pages.
Approved briefs, concrete changes
The next client variant, made concrete.
Start with bounded presentation changes. Preserve approved offers, destinations, and purchase behavior while you review the experience.

Understanding credits
Pay for the work your request needs.
Credits reflect AI usage across inspection, clarification, generation, and verification. There is no fixed credit price per variant.
- A focused copy editA smaller scope usually needs less work than a layout change.
- A layout or styling changeMore page context and review can increase usage.
- A multi-page variantEach page adds context and verification work. Usage varies with complexity.
Start with the 7-day trial and check your usage in Plan & credits to choose an allowance based on your own work.
Paid plans renew monthly until cancelled. Cancel before renewal to prevent the next charge. Payment refunds are separate from technical credit refunds; see the billing terms. Start a request while you have credits. We’ll finish that request even if it uses your remaining balance. Credits reflect actual AI usage. Technical failures are refunded. Monthly credits expire without rollover; each new allowance starts in full. Extra credit packs are available to active paid subscribers: 100 for $10, 250 for $25, or 500 for $50, USD before tax. Purchased credits never expire.
