What these tools cover
Writing comes with small, fiddly checks. An essay has a word limit, a social post has a character limit that counts emoji differently, a list pasted from a spreadsheet is full of duplicates, and two drafts of a contract need to be compared line by line. The text tools handle those jobs as you type or paste.
They fall into six groups: counting and checking (word counts, character limits, readability scores), transforming (case conversion, sorting and de-duplicating, comparing texts, full-width and half-width characters, numbers in words), alphabets and scripts (Uzbek Cyrillic and Latin, transliteration, Simplified and Traditional Chinese, Japanese to romaji), generating (placeholder text, stylised Unicode text, usernames), reference (citations and symbols) and writing with AI.
Alphabets, scripts and local formats
Many forms only accept one script. Japanese to romaji spells names the way a Japanese passport does, with long vowels dropped and the 37-character limit counted. The full-width converter fixes the 全角 and 半角 characters that Japanese forms reject, including the half-width katakana banks require for transfer names. The Uzbek converter switches between Cyrillic, today's Latin alphabet and the 2026 spelling, and the Chinese converter maps Simplified and Traditional characters with regional vocabulary. The keyboard layout converter fixes text typed on the wrong layout (ghbdtn → привет) across 16 layouts.
Number to words writes numbers and money amounts out in 23 languages with the grammar each country's documents expect: US checks with 56/100, Indian lakh and crore ending in "Only", Russian сумма прописью, Chinese 人民币大写, Arabic tafqeet and Thai BAHTTEXT, with pages for invoice amounts and cheques.
Accuracy you can rely on
Counts are Unicode-aware, so accented letters, emoji and non-Latin scripts are counted the way people expect. Readability scores follow the published formulas, such as Flesch Reading Ease and Flesch-Kincaid Grade Level. Where a platform publishes its own rules, such as how X counts links, the counter follows those rules rather than a simple character count.
Private by default
Drafts, essays and unpublished work are the kind of text people do not want stored on someone else's server. Apart from the Write with AI group, these tools run in your browser; where a tool remembers your last text so it survives a refresh, it saves it in your browser's local storage, and a Clear button removes it. The citation tool also goes online: when you look up a DOI, ISBN or URL, that identifier is sent to look up the details, and the tool says so.
Writing with AI
The Write with AI group adds a paraphraser, a summarizer, a grammar checker and writers for essays, paragraphs, emails, Instagram captions, headlines, meta descriptions and short stories. Unlike the rest of the category, these tools send your text to our server and on to Anthropic's Claude model to write the result; nothing is stored, and they share a free allowance of 20 requests a day. Check facts before you use a draft.
