Measure text accurately. Eliminate layout thrashing. Stay 508 and WCAG 2.2 compliant — even in complex, dynamic interfaces.
Built for teams who can’t afford janky UIs or failed audits.
Traditional accessibility tools rely on DOM measurements that trigger expensive reflows and introduce jank.
ReadCheck changes that.
Using Pretext — the breakthrough text measurement engine from Cheng Lou (ex-React team) — ReadCheck performs fast, accurate multiline text analysis entirely in userland, without forcing browser layout recalculations.
No more layout thrashing during audits.
No more jank in production UIs.
Full support for WCAG success criteria around text resizing, readable line lengths, and cognitive load.
Zero Reflow Accessibility Testing
Run thousands of text measurements during audits without slowing down the page or triggering performance warnings.
Designed for High-Stakes Environments
Perfect for government systems, enterprise CRMs, and regulated platforms where layered consulting teams (primes, subs, and vendors) demand both performance and provable compliance.
Focus Areas
WCAG 1.4.4 Resize Text predictions at multiple zoom levels
Optimal line length and readability scoring (especially for elderly and low-literacy users)
Overflow and truncation risk detection in dynamic content
Zero-jank virtualized lists, feeds, and generative UIs that remain fully accessible
Built on the Pretext Revolution
Pretext lets developers escape the old CSS/DOM constraints. ReadCheck extends that power into accessibility tooling — combining blistering performance with real compliance value.
Who It’s For
Accessibility consultants and remediation teams working on Section 508 projects
Government contractors and enterprise developers modernizing CRMs and dashboards
Performance engineers who need smooth UIs that still pass rigorous audits
Agencies stacking multiple consulting layers who want a modern, defensible edge
The Pretext wave is here.
Don’t let accessibility become the bottleneck — or the performance killer.
