Free browser-based grammar checker with detailed writing statistics
Slick Write is a free, browser-based grammar and style checker that analyses text for grammatical errors, writing style issues, and detailed writing statistics — including word frequency, sentence length distribution, and vocabulary diversity.

Slick Write is a strong fit if its core strengths match your workflow, budget, and support needs. Use the quick signals below before opening the full review.
Slick Write occupies the ultimate value position in the grammar checker market: completely free, no account required, no feature limits, no upsells. For writers who want basic grammar checking and statistical writing insights without any cost or commitment, Slick Write delivers a functional tool that covers the baseline.
Slick Write's statistics panel is its most distinctive feature relative to other free tools. Alongside grammar error counts, it displays: word frequency distribution (which words appear most often), sentence length distribution (showing whether the writing uses varied or monotonous sentence structures), transition word percentage (a proxy for logical flow), and vocabulary diversity (the ratio of unique words to total words). These statistics provide a quantitative snapshot of writing characteristics that Grammarly's free tier does not surface.
For writers working to develop diverse sentence structures or eliminate overused words, these statistics provide objective measurement of current writing patterns — a baseline for improvement.
Unlike most 'free' grammar tools that enforce word limits, conversion caps, or feature restrictions, Slick Write has no usage limits. Paste a 10,000-word document and receive full analysis. Submit multiple documents in the same session. No account means no tracking, no email marketing, and no upsell sequences. For writers who resent the monetisation patterns of freemium tools, Slick Write's purely free model is refreshing.
Slick Write's grammar detection quality is noticeably below the modern AI-powered tools. It catches clear grammatical errors reliably but misses many nuanced issues that Grammarly, LanguageTool, or ProWritingAid identify. As a free sanity check before publication, Slick Write is useful. As a primary writing improvement tool, its grammar detection gap is a real limitation.
Score: 6.7/10 — Best permanently-free grammar statistics tool; grammar detection quality below premium tools is the consistent honest limitation.
