Math Formula Generator
Type LaTeX, see it rendered live, then copy as a high-resolution PNG image, SVG, or in multiple formats (MathML for Office, Python/SymPy, Unicode for plain text). Includes a handwriting recognition pad for drawing formulas.
LaTeX Preview
Full-featured LaTeX editor with live preview, symbol palette, document templates, command autocomplete, and export to PNG/SVG/PDF/HTML/Markdown. Supports sections, theorems, lists, math environments, and inline formatting.
Fancy Text Generator
Convert plain text into 20+ Unicode font styles (bold, italic, script, fraktur, double-struck, monospace, circled, and more). Click any style to copy. Works everywhere since the characters are real Unicode, not formatting.
Chess Coach
Play timed games (15+10 and more) against twenty characters from absolute beginner (200) all the way to raw Stockfish (3600+), each with their own personality, strengths, and weaknesses. A built-in coach hints at the right piece if you think too long, warns you in orange/red before you commit a mistake or blunder, estimates your rating as you play, and hands you a post-game grandmaster review. Tracks your progress and game history in your browser, with an optional online leaderboard. Powered by Stockfish running in your browser.
