Does Grammarly support Indonesian?
Yes, with limits. Grammarly added Indonesian on 11 March 2026 among 17 more languages, as red-underline corrections for spelling and basic grammar, labelled as a beta. Its official language page says that clarity, fluency and tone suggestions, which are paid blue underlines, are available for English, Spanish, French, German, Portuguese and Italian, and that paragraph rewrites are limited to the same languages. One support article words the beta more broadly, so Grammarly's own pages are not fully consistent. We checked all of this on 1 November 2026.
In a signed-out test on that date, Grammarly underlined every non-standard word we planted in a short Indonesian paragraph. So the accurate statement is not "Grammarly cannot do Indonesian". It is "Grammarly flags Indonesian spelling, but explains it in English and offers no style coaching".
Why Indonesian needs its own authority
Indonesian spelling is set by the language agency, Badan Pengembangan dan Pembinaan Bahasa. Its official rules are EYD Edisi V (2022) and its dictionary is the KBBI, now in its sixth edition. Many everyday spellings that people type are non-standard (tidak baku) in those sources: praktek instead of praktik, apotik instead of apotek, resiko instead of risiko, silahkan instead of silakan, and dimana written as one word instead of di mana. A writer who sends a thesis, a government letter or a job application needs to know which form the authority prescribes, and why.
What AdeptWrite does for Indonesian writers
The Indonesian site lives at /id/. Its Cek Ejaan checker follows EYD V and its Cek KBBI tool looks up whether a word is standard. Both use an open Indonesian word list plus AdeptWrite's own verified pairs of standard and non-standard words, and each fix shows the reason, so you learn the rule rather than just accept a change. AdeptWrite does not copy the KBBI: it links to the official dictionary for definitions, and it only claims what its data covers.
Beyond spelling, the Indonesian site offers the paraphraser, grammar checker, summarizer, translator and plagiarism checker, with Indonesian-language pages and rupiah prices for paid plans.
Who should use which
| Your situation | Better fit |
|---|---|
| Writing English emails and reports | Grammarly, for live clarity and tone suggestions |
| Writing a thesis, official letter or CV in Indonesian | AdeptWrite, for EYD V and KBBI-based spelling with reasons |
| Switching between English and Indonesian in one day | Use both: Grammarly for English, AdeptWrite for Indonesian |
| Learning Indonesian as a second language | AdeptWrite, because each fix explains the rule |
| Paying in rupiah | AdeptWrite, whose Indonesian site shows rupiah prices; Grammarly's site prices are in USD |
What AdeptWrite does not do
AdeptWrite does not offer live as-you-type suggestions inside every app, and its Indonesian grammar help is lighter than its English. The AI tools can be wrong, and no accuracy figure is claimed. The spelling data covers a verified set of word pairs and a word list, not every case in the KBBI, so for official documents confirm unusual words in the KBBI itself.
