ViSpelling

ViSpelling is a focused spell-checking bot for three languages: Russian, Ukrainian and English, according to its own description. Rather than trying to rewrite or restructure your text, it does one specific, useful thing - it shows you where the mistakes are, highlighting misspelled words in bold so they're easy to spot at a glance rather than having to reread every word carefully. That highlighting approach is worth noting because it's a different, arguably more useful, output style than bots that silently auto-correct everything: seeing exactly which words were flagged lets you learn from your own mistakes over time and decide for yourself whether a flagged word is actually wrong (proper nouns and slang sometimes get incorrectly flagged by automated spell-checkers). For students, people writing in a second language, or anyone drafting something in Ukrainian where good spell-checking tools can be harder to find, this multi-language focus fills a specific need. It's a lightweight utility rather than a full writing assistant - for tone changes or full rewrites, pair it with a broader tool like FixMeBot.
