A1 Multitool

Inspect type, color, SEO tags, structured data, links, HTML, accessibility, performance, tech stack, and overlays locally.

A1 Multitool is a focused inspection toolkit for the page you're on. Open the popup and switch between modes. Each check runs locally, after you click, on the current tab only. Report tabs lead with actionable findings and keep the raw page data below as supporting evidence. Type: hover to highlight, click any element to read its computed font, size, weight, spacing, and color. Lists every font used on the page. Color: sample page colors, copy HEX/RGB/HSL values, review the page palette, and check contrast. SEO: review indexability, title and description length, canonical and robots tags, Open Graph and Twitter tags, social preview data, JSON-LD types, and headings. Links: compare internal and external links, review nofollow usage, see external domains, and identify practical link-review findings. HTML: find duplicate IDs, empty attributes, missing alt/lang/title values, and structural issues. Accessibility: check unlabeled inputs, nameless buttons, missing alt text, heading skips, landmarks, and priority fixes. Performance: review load milestones, request count, transfer size, largest resources, third-party hosts, and suggested next checks. Tech stack: detect common frameworks, analytics, ad tech, consent tools, embeds, CDNs, and page asset hosts. Overlay: outline page elements or hover to measure pixel sizes. Use the separate-window button when you want the tool to stay open while you inspect, scroll, or compare the page. Privacy: A1 Multitool runs on-device. It does not send page content, scan results, reports, browsing history, or settings to a server.
