What it is

Tensetti Plain Language Checker is a web tool for finding clarity problems in technical documents. The product description calls it ClearSpec and lists 22 checks spanning action clarity, sentence structure, terminology, safety language, and consistency. The maker says its rules are deterministic, so identical inputs produce identical results. The free checker analyzes pasted text locally in a browser Web Worker and says it does not send text to servers, analytics, or logs. It accepts up to 1,000 words and displays the first ten findings, without requiring an account. The tool reports findings and editing actions but does not rewrite text or decide whether safety content is safe. Pro costs €120 a year and adds larger local documents, all findings, a personal termbase, and local TXT, Markdown, and DOCX opening. DOCX parsing does not interpret layout, images, tables, or cross-references. Pro also exports PDF and CSV reports, though PDF input is not offered. Team costs €349 a year and adds five users, shared termbase and style profile, approved exceptions, batch queue, and review history. The maker says Jonatan Tensetti builds and maintains the tool in Sweden.
