Smart edits and annotations
Only for Mac

Mac
InSpec is a CSS editor annotator for any web page. Click an element on the page, dial in the styles with visual editors, and your edits stay put through reload, navigation, even quit and relaunch. Each edit is keyed to the page's URL. You can also add annotations and notes to any element on the page.
When you're done, copy your edits out as actual CSS rules, or even save them directly to your local CSS files. The "now translate this cascade fight back into my source CSS by hand" tax is just gone. InSpec is perfect for a designer-developer workflow, stakeholder presentations, or vibe coding sessions. In addition to InSpec providing CSS, you can also easily save your edits and annotations as images in a variety of viewport widths with a single click.
WHY THIS EXISTS
• Edits that survive a reload. DevTools forgets every change the moment you reload. InSpec keys overrides to the page's URL and reapplies them on every load.
• Built for the handoff. Every edit captures which stylesheet, selector, and original value it overrode. The Source view rewrites your changes as ready-to-paste CSS rules, grouped by the file you'd commit them in.
• An interface for editing, not debugging. Real macOS color picker. Visual builders for box-shadow, gradients, border-radius, flex, cubic-bezier. One-click eye toggles to A/B compare. The panel is shaped around changing styles, not just reading them.
• Spacious, not stuffed in a sidebar. InSpec is its own window. Responsive viewport presets, inspect mode, alignment guides, and the page-overrides badge all live in the top bar, always one click away.
• Breakpoint-aware overrides. Edit a property whose source rule sat inside an @media block and the override scopes to the same query — no leak to other breakpoints, no leak to the base style. Per-property picker for any edit's applies-to set.
• One click to A/B compare overrides against the original without losing them. Per-property eye toggles for finer pauses.
• DOM nav built for editing. Right-click any element to walk ancestors and children inline.
• Local files too. Open any local .html with relative resources resolving correctly — review designer mockups before they're deployed, and save changes directly to file.
• Annotations let you record stakeholder feedback or provide feedback to coding agents in one pass.
InSpec is featherweight and native. SwiftUI + WebKit + a small injected JS inspector. No telemetry, no servers, no remote dependencies.
