Break each screen into its components
Every screen is decomposed into its listed components, since a spec built around named elements is far easier for a developer to implement against than a full-screen description.

Your inputs
Generate a developer-ready screen specification
Enter one screen per line as Screen | components (semicolon-separated) | validation rules (semicolon-separated, blank if none) | responsive behavior. List each screen needing a written spec.

How it works
Attach validation rules to the spec
Any validation rules you provide are attached explicitly, turning implicit design assumptions into a written requirement.
State the responsive behavior per screen
Each screen carries its own note on what changes at the relevant breakpoint, so responsive behavior is not left to developer interpretation.
Frequently asked questions
Does SpecSnap extract actual pixel measurements from my design file?
No — this is a structuring tool for the specification text you provide, not a design-file measurement extractor. Pair it with your design tool's own inspect/measure feature for exact values.
What if a screen has no validation rules?
Leave that field blank — the generated spec will note "no validation required" rather than silently omitting the section.
How detailed should the components list be?
List every interactive or meaningfully distinct element (fields, buttons, cards) — the more complete the list, the more useful the generated spec.
Can I use this spec directly as a dev ticket?
Yes — copy the generated output into your ticketing tool, or use Screen2Ticket if you want it already formatted as an implementation ticket.
How we compare
| Capability | MVPHub | Writing specs manually in a doc | Zeplin or a full design-spec platform |
|---|---|---|---|
| Structured component + validation + responsive format | ✓ | — | ✓ |
| Consistent structure across every screen | ✓ | × | ✓ |
| Automatic pixel/measurement extraction from design files | × | × | ✓ |
| No account, paste and get a spec instantly | ✓ | ✓ | × |
MVPHub gives every screen spec the same reliable structure instantly. A full platform like Zeplin adds automatic measurement extraction directly from design files, which this tool does not do.
