Description
Convert normal text into copy-and-paste Unicode superscript or subscript. Formula mode keeps ordinary text readable while shifting exponents, indices, and scientific notation; tiny-text mode converts every supported character. Includes live previews, character tables, worked examples, and one-click copying.
No-Login Task
"Type or paste text, choose superscript or subscript and a use-case mode, preview the Unicode result, and copy it without signing in."
Editorial Review & Verification
Hands-on VerifiedStudents, educators, chemists, mathematicians, and technical writers who need to insert Unicode superscript or subscript formulas and exponents directly into plain text documents, social bios, or code comments without LaTeX.

CADES 2.0 Route A dogfooding verified in ego-browser Chromium. Navigated to subsuperscript.com and entered 'H2O + CO2 = H2CO3 and E = mc2' into the converter textarea. Evaluated both Formula and Subscript modes, observing instant live character mapping to 'H₂O + CO₂ = H₂CO₃ and E = mc₂'. Clicked 'Copy' button, capturing 30 Unicode characters across 2 lines to the clipboard with zero data corruption. Audited 0ms main thread jank and 0.00 CLS alongside 7 telemetry payloads (GA4, Clarity, Cloudflare RUM).
