Thirty Math Symbols and Twelve Decoration Patterns
Find a math symbol or Greek letter and copy it with one click, or decorate your text with math symbols. Search thirty curated math symbols and Greek letters, copy an exact character, or compare twelve fixed text-decoration patterns. The picker includes operators, selected Greek letters and set symbols. It is not a complete Greek alphabet, an equation editor, a fraction formatter or a calculator. The decoration inserts symbols around source clusters; it does not translate prose into mathematical notation.
Finding and copying a symbol
- Search symbols by collection name, literal character or U+ code point. Every query word matches the combined name/code-point metadata; outer whitespace is ignored and metadata ignores case.
- Use a named Copy symbol button and inspect Selected symbol. Wait for confirmation; if access fails, select the complete character manually.
- Enter Source text to compare twelve patterns. Each readonly result shows its complete value, local UTF-16 unit count and a permanent named Copy button.
- Clear text empties source only. Reset restores Mathematical Beauty and clears Search, selection and feedback. Search changes clear selection and invalidate pending Copy feedback.
How Math Text Decoration Works
The browser segmentation API groups source text into extended grapheme clusters before insertion. Between patterns add fixed symbols only between adjacent non-whitespace clusters. After patterns append a cyclic symbol after each non-whitespace cluster, including the last. Original whitespace does not advance cycles. Frames wrap the entire source with literal prefix/suffix strings.
Spaces, tabs, CRLF, CR and LF remain unchanged and in order. This replaces the old code-unit splitting and whitespace collapse. Combined accents, emoji sequences and Indic clusters stay whole before decoration. Empty or whitespace-only input creates no results; twelve slots are not a promise of twelve unique strings.
Input limits are 25,000 UTF-16 units and 5,000 grapheme clusters. Exact insertion sizes are checked before allocation against 100,000 units per result and 500,000 total. Unsupported controls, incomplete Unicode or a missing segmentation API show an editable error rather than silently shortening the source. Counts are not visible width or destination limits.

Lookup, identity checks and heading drafts
Known character lookup
Find Integral at U+222B or Sum at U+2211 when your notation already calls for that character.
Identity inspection
Compare N-ARY SUMMATION U+2211 with GREEK CAPITAL LETTER SIGMA U+03A3. They are different characters.
Short heading drafts
Try a decorative border while keeping meaning in ordinary words. The inserted operators do not make a valid equation.
Multiline notes
Retain existing line breaks during decoration and check actual font coverage and wrapping in your editor.
Delta, Omega and other coverage gaps
The picker label Delta identifies INCREMENT U+2206, not GREEK CAPITAL LETTER DELTA U+0394. Neither Greek capital delta nor Omega is in this thirty-entry picker. Do not infer coverage from a pattern name or a similar-looking glyph. Greek Cycle uses eight fixed letters, not the full alphabet. Pi Border replaces the misleading Scientific Notation label: it adds a frame and does not express powers of ten.
Code points identify text; fonts, speech and receiving-field permission are separate. Copy confirmation only confirms the clipboard write. A copied operator is not guaranteed to be a valid programming-language identifier, expression or equation. If Copy fails, select the complete readonly value and inspect the pasted draft.
Confirming what was copied
Use U+ searches to disambiguate lookalikes. Start with a short phrase when comparing Between and After placement. Avoid applying decorative cycles to formulas that need their original meaning preserved. The tool performs no evaluation, normalization, LaTeX parsing or equation layout.
