A2Z Tools Plain Language Analyzer in 2026: Pricing

A2Z Tools Plain Language Analyzer checks English drafts for features that may make instructions and other writing harder to follow. It flags complex words, terms on the GOV.UK avoid list, hidden verbs, “shall” in requirements, double negatives, passive voice, long sentences, and long words, linking each finding to its guideline source. The tool estimates a Flesch-Kincaid reading grade and compares it with a target for the intended audience. Its defaults are tailored to general-public writing, service instructions, and professional readers: sentence thresholds are over 25, 20, and 30 words respectively, while grade targets are 8, 7, and 12. Users can add an organization-specific jargon list and pair terms with simpler alternatives using an equals sign. Findings can be downloaded as a CSV for an editor. The analyzer processes pasted, typed, or dropped text in the browser tab; it says text is not uploaded, logged, stored, or sent to analytics. It checks English only, and its word lists combine US and UK guidance. The free online tool is listed at 0.00 USD per free.
