Is this writing editor really free?

Yes, 100% free with no hidden costs, no freemium tiers, and no signup required. All features are available immediately — readability scoring, sentence highlighting, adverb detection, passive voice alerts, complex word suggestions, and export options.

Is my writing private?

Absolutely. Your text never leaves your browser. Everything is processed locally using JavaScript — no data is sent to any server. Your documents are saved in your browser's local storage, which only you can access.

How does the readability grade level work?

The editor uses the Automated Readability Index (ARI) to calculate a U.S. grade level for your text. A Grade 9 target (the default) means your writing is accessible to the average adult reader. You can adjust the target grade level up or down depending on your audience.

What do the highlight colors mean?

Yellow highlights hard-to-read sentences. Red highlights very hard-to-read sentences. Blue highlights adverbs, passive voice, and qualifiers/weakeners. Purple highlights complex words that have simpler alternatives — hover to see suggestions.

How is this different from other writing editors?

Most writing editors require paid subscriptions or accounts. This tool is 100% free with no paid tiers, no accounts, and no data leaves your browser. You get readability grading, all highlight categories, formatting tools, import/export, dark mode, and auto-save — all completely free and private.
