Tools for Book & Technical Content Writer
Word counts, grammar checks, and text tools built for people writing something longer than a tweet.
Long-form writing — a book manuscript, technical documentation, anything longer than a social post — has different needs than everyday writing: consistent formatting across a much longer document, word counts that actually matter for a contract or submission requirement, and grammar checking that holds up across dozens of pages, not just a paragraph. This collection is built around that specific scale, not shorter, quicker writing tasks.
