Frequently asked questions
- Is my text stored when I use Letters Only Filter? — No. Letters Only Filter processes the text in the page itself. Nothing is transmitted or saved, which matters for unpublished or confidential writing.
- How much text can I paste in? — Tens of thousands of words is comfortable. The only real limit is how much your browser will hold.
- Does it handle languages other than English? — Yes — full Unicode support, so Cyrillic, Arabic, Chinese, Japanese, accented Latin and emoji are all handled properly.
- Will formatting be kept? — No. Pasted content is treated as plain text, so bold, colours and links are dropped.
