Install Extension →SpinCheck is built to help people think clearly about what they read — not to push them toward a conclusion. It scores bias on a 0–10 scale, surfaces specific evidence, and always steel-mans the opposing side. Use it on left-leaning articles, right-leaning articles, and everything in between.
