Free Indonesian Grammar Checker: Check & Correct Online
Introduction
Looking for a reliable indonesian grammar checker to proofread essays, emails, or web copy? Rephrasely offers a free, AI-powered Indonesian grammar checker that identifies grammatical errors, punctuation mistakes, and style issues specific to Bahasa Indonesia.
The tool supports contextual suggestions (including affixation fixes like me-/di-), spacing for prepositions, and register adjustments for formal or informal text. You can try it instantly at Rephrasely.
How It Works
Using the Indonesian grammar checker is fast and straightforward. The engine combines linguistic rules for Indonesian with machine learning to provide accurate corrections and clear explanations.
- Paste or type your Indonesian text into the checker on Rephrasely.
- Select "Indonesian" as the language (the tool detects language automatically if you prefer).
- Click "Check" — the checker highlights errors and suggestions inline, grouped by type (grammar, punctuation, style).
- Review suggestions one by one or accept all changes. For longer documents, use the Composer to rewrite or adjust tone.
- Optionally run a plagiarism scan with the plagiarism checker or test originality with the AI detector.
Examples: Before and After (Bahasa Indonesia)
Below are common errors Indonesian learners and native speakers sometimes make, with corrected versions and short notes.
| Before | After | Note |
|---|---|---|
| Saya tinggaldirumah ibu karena sibuk. | Saya tinggal di rumah ibu karena sibuk. | Prepositions like "di" and "ke" must be separated from the noun. |
| Dia mebeli buku baru kemarin. | Dia membeli buku baru kemarin. | Common spelling error: correct affixation is "membeli". |
| Aku telah pergi ke pasar, dan aku membeli-beli sayuran. | Saya sudah pergi ke pasar, dan saya membeli sayuran. | Adjust register (aku → saya) and avoid unnecessary reduplication "membeli-beli". |

Tips: Indonesian-Specific Best Practices
- Watch "di/ke/dari" spacing: Always separate these prepositions from the following word (e.g., "di rumah", not "dirumah").
- Check affixation: Prefixes and suffixes (me-, ber-, ter-, -kan, -i) change root words; incorrect affixation is a frequent mistake for learners.
- Mind reduplication: Use reduplication (buku-buku, anak-anak) only when implying plurality or distribution; avoid unnecessary repetition created by literal translation.
- Choose the right register: Switch pronouns (aku vs saya) and verb particles for formal documents. Use the Composer to rewrite text into a consistent register.
- Relative clauses with "yang": Avoid stacking "yang" unnecessarily (e.g., "rumah yang mana yang kemarin" → "rumah yang kemarin").
- Check numeral and date formats: Indonesian uses specific formatting for dates and currency; the grammar checker flags inconsistent formatting.
- Keep context in mind: Some corrections are contextual; review suggestions rather than accepting blindly, especially for names, slang, or regional words.
