Worked examples for technical screenshots

Published product examples

These screenshots are served from DevSnap's current US App Store listing, checked on September 28, 2026. They show the product UI, not a customer case study, a benchmark, or a promise that every source image will have the same result.

A whiteboard handoff becomes a Mermaid draft

This published App Store screenshot shows a handwritten system design as the input, then a diagram and Mermaid source in DevSnap. The screen identifies the structured path as AI Transform.

What a human checks

• Compare every node label, arrow direction, and relationship with the source image.
• Treat the Mermaid as a draft before adding it to a design note or runbook.
• AI Transform is optional and uses an online cloud and AI processing path.

A stack trace stays tied to its context

This published App Store screenshot pairs a stack trace with a result view that keeps nearby code context visible, plus Copy and Export Markdown actions.

What a human checks

• Verify paths, line and column numbers, error text, and surrounding code against the original image.
• Keep the command or event that produced the failure with the excerpt you share.
• Choose Text Scan for on-device cleanup; choose optional AI Transform only when you want its online structured-output path.

Copyable handoff references

These are harmless, original technical samples written for this page. They are not captured DevSnap output or accuracy measurements. Put a sample in an editor, capture it at a readable size, and compare the recognized text with this source before copying or exporting it.

Text Scan is the on-device cleanup option. Optional AI Transform uses online cloud and AI services for structured Markdown, summaries, and Mermaid diagrams. Small text, cropping, contrast, and the source image can change what needs review.

Choose the processing mode for your own input

Text Scan

Use Text Scan for local, on-device cleanup when you need recognized technical text to stay off the DevSnap transform service. Review it before reusing it in an issue, handoff, or runbook.

Optional AI Transform

Use AI Transform when you want structured Markdown, summaries, or a Mermaid draft and are comfortable with the online processing path. Check its result against the source before treating it as a record.
