Tensetti Plain Language Checker
Sweden
What it is
Tensetti Plain Language Checker, also called ClearSpec in its product description, checks technical documents for clarity problems that can make instructions difficult to understand or use. It runs 22 named checks across areas such as action clarity, sentence structure, terminology, safety language, and consistency. The maker says the checks are deterministic, so repeating the same input yields the same output. Its free web checker analyzes pasted text in the browser and accepts up to 1,000 words, showing the first ten findings without requiring an account. The checker reports findings and editing actions, but it does not rewrite text or determine whether safety content is safe. Pro costs €120 a year and adds larger local documents, all findings, a personal termbase, local TXT, Markdown, and DOCX opening, and PDF and CSV report exports. Team costs €349 a year and adds five users, shared termbase and style settings, approved exceptions, a batch queue, and review history. DOCX parsing does not interpret layout, images, tables, or cross-references.

The verdict
