Norwegian grammar checked with the reason attached
Paste Norwegian and every issue is underlined where it happens, labelled spelling, grammar, punctuation or style, with the reason attached. Norwegian is written in the Latin alphabet, and three genders, compounds, og and å are what a checker has to get right in it. This one shows the rule each time, not just the change, so you can accept the fix, ignore it, or learn from it.
How to check Norwegian grammar
Three steps. The third is the one most checkers leave out.
1
Paste or upload the Norwegian
Type, paste or drop in a document. Norwegian is already selected as the language on this page; the menu above the editor also offers the variants described below. If the text turns out to be something else, the detector says so and you can change it.
2
Read the flags
Every flag is underlined in the text and listed beside it. Spelling and grammar flags are errors; punctuation and style flags are judgements, and the label tells you which is which before you decide.
3
Accept, ignore or read why
Click a flag to see the fix and the rule behind it, then accept it or ignore it. Norwegian has rules that speech does not reveal, and the reason is there so the same error is not made twice.
What the checker looks at in Norwegian
The parts of Norwegian grammar and spelling where a checker has to know the language, not just the words.
AgreementBokmål has three genders (en bil, ei bok or en bok, et hus) with a feminine that may be written as common gender, and adjectives agree: et stort hus, den store bilen. The definite article is a suffix, doubled with an adjective (det store huset).
VerbsNo person endings. The present takes -r (hun skriver), the infinitive after å does not (å skrive), and the verb stands second in a main clause. Past-tense forms have accepted alternatives (kastet or kasta), and the checker keeps the one the text uses.
Spelling and diacriticsæ, ø and å are letters of the alphabet. The acute is used in a few loanwords and to mark stress (én, allé, idé).
PunctuationA comma comes after a subordinate clause that opens the sentence and before men; before at, som and fordi it is not used. Decimals take a comma.
Capital lettersDays, months, languages and nationalities are lower case (mandag, januar, norsk). De as a formal you is capitalised but rarely used today.
Common mistakes in Norwegian writing
Five errors Norwegian readers notice at once, and what the checker does with each.
og or å
Og is and; å marks the infinitive (jeg liker å lese). They sound the same in most dialects, and jeg liker og lese is the classic error.
Compounds written as two words
Lammekoteletter is lamb chops; lamme koteletter are paralysed chops. Bokmål writes compounds as one word.
da and når
Da for a single event in the past (da jeg var liten), når for repeated events and the future (når jeg kommer hjem). The rule of thumb: den gang da, hver gang når.
ennå and enda
Ennå means still or yet in time (han er ennå ikke kommet); enda intensifies (enda bedre) or means even so. The distinction is kept in writing.
Verb-second after a fronted phrase
I morgen reiser vi, not i morgen vi reiser. Whatever opens the sentence, the verb comes next.
Formal and informal Norwegian
Norwegian uses du with almost everyone in writing, including officials; De is archaic outside a few ceremonial contexts. Formality is carried by vocabulary and sentence shape, not by a pronoun.
The checker flags a mixed register as style rather than as an error, so the decision stays yours. If a whole text needs to move from one register to the other, the tone changer rewrites it in one pass.
Who checks Norwegian here

Pupils and students in Norway, and Norwegians who write English all day and Norwegian rarely.
2
Businesses answering Norwegian customers, where og/å and a split compound are noticed at once.
3
Adult learners preparing for the norskprøven who want each correction explained.
Norwegian grammar checker FAQs
Is the Norwegian grammar checker free?
Yes. Check Norwegian without an account, within the per-check and daily word allowances shown beside the editor. Signing in raises them, and Pro removes the guest limits and the ads. The pricing page lists what each plan includes.
Which Norwegian does it check?
The checker targets Bokmål, the written standard used by the large majority of Norwegians. Nynorsk has its own forms and is not converted; if the text is Nynorsk, set the language to Auto and the checker leaves the Nynorsk forms alone. Norwegian is preselected on this page; change the language menu above the editor if the text is a different variant.
Does it correct Norwegian spelling as well as grammar?
Yes, and in Norwegian the two overlap. The everyday errors are og/å (and/to), the split compound (særskriving), and the pairs da/når, enda/ennå, ovenfor/overfor. Bokmål allows many optional forms (boka/boken, kastet/kasta), and consistency within a text is what matters. Each of these is underlined where it happens, labelled spelling or grammar, with the standard form and the rule beside it.
Will it rewrite my Norwegian?
Not unless you ask it to. A check corrects what is wrong and leaves your sentences as you wrote them; every change is a separate flag you accept or ignore. The Improve and Rewrite passes, which do change wording, are separate buttons, and the paraphraser is a separate tool.
Can I check a whole Norwegian document?
Yes. Paste the text or drop in a .docx, .pdf or .txt file; the document is checked paragraph by paragraph and the corrected version can be copied or exported. Long documents are checked within the per-check allowance and continue as you scroll.
Is it useful if I am learning Norwegian?
That is where the reason attached to each flag earns its keep. Bokmål has three genders (en bil, ei bok or en bok, et hus) with a feminine that may be written as common gender, and adjectives agree: et stort hus, den store bilen. A learner sees which rule was broken, not just the corrected word, and can accept the fix or read why it was raised before deciding.
After the check
Translate the corrected Norwegian, change its tone, or shorten it. One plan covers every tool.
Each page opens the checker with that language already selected and explains what it looks for in it. The picker above the editor covers more than seventy languages in all.
