Best fit
A real product improvement is difficult to judge because its screenshots use different states, sizes, crops, or unsupported captions instead of a credible comparison.

Package requirements: PNG, JPEG, WebP, or other supplied screenshots that the active environment can inspect. Agensi, Gumroad, Product Hunt, and owned product-page dimensions when current specifications are supplied or verified. Agents that can inspect images and create SVG or supported raster output.

What problem does Before/After Proof Pack solve?
A real product improvement is difficult to judge because its screenshots use different states, sizes, crops, or unsupported captions instead of a credible comparison.
Use it to
- Normalize real before-and-after screenshots to a comparable viewport, state, and crop
- Create Agensi, Gumroad, Product Hunt, or owned-site comparison layouts
- Write observable captions and alt text tied to the supplied evidence
- Flag conversion, accessibility, speed, sales, or preference claims that the screenshots do not support
What it returns
- Normalized before-and-after screenshot pairs
- Annotated comparison board and marketplace gallery layouts
- Truthful captions, alt text, and claim-evidence mapping
- Unsupported-claim and comparability warnings
A representative input and result
input Before: dashboard-old.png
After: dashboard-new.png
Claim: missing states are now visible and actionable
Evidence: fixture includes loading, empty, and error routes
Target: 1600x900 gallery image and square thumbnail
result Comparability: PASS after matching the 1440x900 content viewport and using the same empty-project fixture.
Observable changes: empty state now names the condition, offers one primary action, and preserves navigation context.
Unsupported claim: remove 'increases activation' because no activation data was supplied.
Assets: paired 1600x900 board, square detail crop, caption, alt text, and claim-evidence table.
Access and approval boundaries
- Read access to supplied screenshots, evidence, brand constraints, and marketplace specifications.
- Write access only to the selected local output directory.
- Uploading, publishing, or replacing marketplace media requires separate approval.
Known limitations
- Pairs with different content, viewport, authentication state, or test data may not support a direct comparison.
- The workflow can normalize framing and annotation but must not materially alter the underlying product result.
- A visible interface improvement does not establish higher sales, conversion, accessibility, or performance without separate evidence.

Questions
Does it create fake before-and-after results?
No. It works from supplied real states, preserves the underlying result, and flags unsupported or non-comparable claims.
What makes two screenshots comparable?
They should show the same product, content or fixture, state, viewport, zoom, and relevant crop unless a difference is explicitly disclosed.
Can it resize images for marketplaces?
Yes. It can create layouts for verified target dimensions while keeping the important evidence readable and crop-safe.
Does it write captions and alt text?
Yes. Captions and alt text describe observable differences and avoid turning unmeasured outcomes into claims.
How is it different from Product Image Creator?
It specializes in proof integrity and comparable before-and-after evidence rather than general product imagery.
Can it publish the assets for me?
Publishing or replacing marketplace media remains a separate approval step.
Before/After Proof Pack keeps proof and approval boundaries visible.
The listing includes the tested package, realistic samples, declared permissions, and known limitations.
