Why use this tool for Polish?

How It Works — Step by Step for Polish
- Paste or type your Polish text. The checker accepts plain text, documents, or clipboard input. Make sure your keyboard uses Polish diacritics (ą, ć, ę, ł, ń, ó, ś, ź, ż) for best results.
- Select Polish (Polski). Choosing the language ensures the AI applies Polish grammar rules, not generic Slavic checks.
- Choose correction modes. Toggle grammar, spelling, punctuation, and style. You can also select register (formal vs. informal) to adapt suggestions—helpful for letters, emails, or social posts.
- Review suggested edits. Each suggestion includes a short explanation (case, agreement, verb aspect, etc.). Accept or reject individual edits to keep control of nuance and tone.
- Use extra tools if needed. Run a plagiarism scan via Plagiarism Checker, check AI-likeness with the AI Detector, or generate rewritten options with the paraphraser and composer in the AI writer.
- Export or copy corrected text. Save as text or paste back into your document. The tool keeps sentence-level explanations so you can learn from recurring mistakes.

Practical Tips — Polish-Specific Best Practices
- Always check noun endings after numerals: numbers often change the required case (e.g., "5 osób" vs. "2 samochody"). Use the checker to confirm correct case forms.
- Watch agreement between adjectives and nouns. Adjectives must match gender, number, and case (e.g., "nowy dom" vs. "nowa książka").
- Pay attention to verb aspect. Use the imperfective for ongoing or habitual actions and perfective for completed actions; the checker flags mismatches in context.
- Keep diacritics. Missing accents can alter meaning (e.g., "macha" vs. "machać"). Enable diacritics restoration if you often type without Polish layout.
- Use non-breaking spaces between numbers and units (e.g., "10 km") to prevent line breaks. The tool can suggest such formatting fixes.
- When correcting, read the suggestion’s explanation—automatic fixes are helpful, but some stylistic choices (dialect, regional forms) require manual judgment.
How to Make the Most of the Tool
For transactional use—writing emails, product descriptions, or applications—set the checker to "formal" and run a final pass with the plagiarism checker if reusing common phrases. Use the paraphraser to generate alternate phrasing for marketing copy, then verify originality with the plagiarism scanner and naturalness with the AI Detector.
