A better way to work on the web
The extension follows the way web work actually happens: understand the page, make a change, then create something useful from it.
Open the extension on the page you are already viewing and get a focused read on its structure, search visibility and user-facing quality.
Check titles, descriptions, headings, canonicals, links and social metadata.
Measure key performance signals such as TTFB, FCP, LCP and CLS.
Spot contrast, missing labels, alt text and other accessibility issues.
Pick a colour, inspect a typeface or edit CSS live. The Style Editor and layout tools make the invisible parts of a page visible while you work.
Inject and test CSS on any page, then copy the rule when it is right.
Reveal Grid and Flexbox containers, spacing and horizontal overflow.
Hide cookie banners, popups and other distracting elements with reusable rules.
Review how a page travels beyond its tab. Inspect Open Graph and Twitter Card data, collect images and prepare a clean visual for a handoff or presentation.
See the social preview before a link goes live.
Capture the full page, visible area or a selected element.
Annotate, redact sensitive details and export a PNG or multi-page PDF.
Screenshot & editor
Open the built-in editor after a capture and turn a raw screen into a polished visual. Choose a realistic device frame, tune the scene, add frames and export an animation when a still image is not enough.
Place your work in iPhone, Pixel or Galaxy frames and switch finishes in the editor.
Use scenes and keyframes to show a flow, a before-and-after or a product walkthrough.
Export a clean image, animated GIF or MP4/WebM video from the same workspace.

One extension, many small wins
ReadyTools Web Assistant brings the useful middle layer between browsing and DevTools into one calm, searchable toolkit.
Get the page facts that matter for search, speed and accessibility.
See the structure, style and colour decisions behind the page.
Keep sensitive details private and remove friction from the page in front of you.
Privacy by design
The extension is built for practical web work without turning your browsing into a data source. Page analysis, screenshots and editor work happen in the browser whenever the feature allows it.
Screenshots and most page checks are processed directly in your browser.
The extension follows the Chrome Manifest V3 model and ships its own code.
ReadyTools does not sell your browsing history or use the extension as an ad profile.
There is no separate Web Assistant subscription. Your existing ReadyTools Plus or Max plan includes the Pro editor features, so the extension can stay a useful part of the plan you already have.
01
Install the extension from the Chrome Web Store.
02
Connect your ReadyTools account in the extension settings.
03
Use the Pro tools your Plus or Max plan already covers.
No separate checkout, upgrade path or Web Assistant subscription exists. Account connection is used to verify your existing ReadyTools access.
Made for real web work
Whether you are building, reviewing or presenting, the extension gives you context and control without making you open another tool for every small task.
Debug responsive layouts, test CSS, inspect network-facing signals and check the page before opening a full DevTools panel.
Sample colours, inspect typography and create polished device mockups from the sites you are designing around.
Review on-page SEO, social cards, content length, images, links and performance while you research or publish.
Start in a minute
Keep the setup simple and put the useful tools where the work already happens.

Link your ReadyTools account once to use the Pro mockup, animation and export features already included in your plan.
