> About PixelSERP

PixelSERP is built by an SEO who's spent the better part of a decade in content and search, and got tired of eyeballing character counts and guessing how a title would actually render. So the tools measure real pixel width, the way Google actually truncates.

Every tool here runs entirely in your browser. Nothing you type is ever sent to a server, logged, or stored. Check the network tab if you don't believe it. Free means free, not a lead-gen funnel.

More tools are on the way: a ChatGPT citations simulator is next. Follow along on X for updates, or just bookmark this page.

Common questions

Yes, entirely. Among free SEO tools online, PixelSERP has no signup, no paywall, and no email capture. Everything runs client-side in your browser, so there's no server cost tying free access to a catch.
No. Every tool processes your input locally in the browser and never transmits it anywhere. Close the tab and it's gone.
If you're optimizing an existing page, start with the SERP Simulator to check your title and description truncation. If you're planning a ChatGPT ad campaign, use the Ad Simulator to mock up creative before you brief anything. The Capitalization Tool is the fastest way to get a consistently-styled title in seconds.
A ChatGPT citations simulator is next in the queue, showing how your brand appears as a cited source inside AI answers. After that, a keyword clustering tool and an AI visibility checker.
