Does it support multi-line text?
Yes. Each line is processed independently. Import from TXT file or paste directly.
Is my text uploaded to a server?
No. All text processing happens entirely in your browser. Data never leaves your device.
Are there preset templates available?
Yes. Built-in presets include HTML tags, quotes, brackets, Markdown symbols, and more.
Will it lag with large amounts of text?
