Spelling Checker

The checker analyzes input text to locate orthographic errors and propose corrections based on a reference lexicon and language models. It accepts a single block of text or larger documents, and returns a structured result that highlights misspellings, provides suggested replacements, and assigns a confidence score for each item. It can operate in strict or lenient modes.
Conceptually, the tool performs tokenization, normalizes tokens, and checks each token against the lexicon. For each candidate correction, it computes an edit-distance score and evaluates contextual fit using n-gram statistics. It also flags likely keyboard mistakes, repeated typos, and words outside the vocabulary, with configurable allowances for proper nouns and technical terms.
Audience and value: writers, students, editors, and QA teams gain faster proofreading, higher consistency, and clearer communication. The tool differentiates itself through live feedback, customizable dictionaries, language packs for multiple locales, batch processing, and export options that integrate into publishing pipelines or learning management systems.
Core features include per-token corrections, optional explanation notes, punctuation handling, capitalization guidance, and safeguards to minimize false positives for proper nouns and domain terms. Typical use cases include academic drafting, professional reports, content creation, and educational material preparation.
