How is AI proofreading better than spell-check?

AI understands context. It catches wrong word usage (their/there/they're), awkward phrasing, tone inconsistencies, and punctuation errors that spell-check misses.

Does it change my writing style?

The default grammar command preserves your style while fixing errors. Use the Professional Tone command if you also want style improvements.

Can I proofread in languages other than English?

Yes! AI models support 100+ languages. The grammar correction works for any language your AI provider supports.

Best Practices & Tips

AI proofreading represents a fundamental leap beyond traditional spell-checking. While spell-checkers compare words against a dictionary, AI proofreading understands the meaning and context of your writing, catching errors that would otherwise slip through.

Traditional spell-checkers miss an entire category of errors: correctly spelled words used incorrectly. "Their" versus "there," "affect" versus "effect," "its" versus "it's" are all valid words that spell-check approves regardless of context. AI proofreading understands which word belongs in each sentence based on meaning, catching these contextual errors reliably.

Beyond individual word errors, AI proofreading identifies structural issues in your writing. Run-on sentences, comma splices, dangling modifiers, and subject-verb agreement errors across complex sentences are all detected. The AI also catches inconsistencies in tone within a single piece of writing, such as shifting between formal and casual language unintentionally.

Build proofreading into your writing workflow at natural breakpoints. After drafting each paragraph, select it and press your grammar shortcut. This real-time proofreading approach is more effective than saving all corrections for the end because you learn from mistakes as you go. Over weeks, you will notice yourself making fewer of the errors the AI keeps catching.

Create tiered proofreading commands for different situations. A "Quick Grammar" command should fix only clear errors while preserving your style completely. A "Deep Proofread" command should also improve sentence structure, word choice, and flow. A "Final Polish" command should perform thorough proofreading plus readability improvements for publication-ready text. Assign each to a different shortcut for quick access.

For non-English proofreading, AI models handle most major languages well. Google Gemini performs strongly across European and Asian languages. Specify the language in your command prompt if you frequently proofread in a specific language other than English to get more accurate corrections. For multilingual documents, the AI can proofread sections in different languages within the same document.

Pro Tips

Create tiered proofreading shortcuts: "Quick Grammar" for preserving your style with minimal fixes, "Deep Proofread" for structural improvements, and "Final Polish" for publication-ready text.

Proofread paragraph by paragraph as you write rather than at the end. You will learn from corrections in real time and write cleaner first drafts over time.

For critical documents, use the popup output mode to compare original and proofread versions side by side before accepting changes.

Specify the target language in your proofreading command prompt when working in languages other than English for more accurate corrections.
