A misplaced comma looks harmless — its consequences aren't. LinkedIn's own data suggests professionals with two or fewer typos/grammar errors on their profile advance noticeably faster than those with many. A job application, a thesis, a client email, a final paper — the moment a reader thinks 'this person is careless,' the message is lost on form, not content. In Turkish, the usual traps are well known: whether 'de/da' is written separately or joined, the 'ki' conjunction versus the '-ki' suffix, 'herkes/herkez,' apostrophes on proper nouns. In English, Turkish writers most often trip on articles (a/the), tense agreement, and homophones like 'their/there/they're.'

Ryna AI does this differently from a red-squiggle tool: it doesn't just flag the error, it explains why it's wrong and which rule applies — so you don't repeat it next time. You paste the text, Ryna lists errors one by one with a 'wrong → right → why' triad for each, and on request produces a clean corrected version separately. Unlike classic checkers that judge sentences in isolation, it weighs the whole text, its tone, and its audience: it won't edit a formal petition and an Instagram caption by the same yardstick. Being built Turkish-first, it catches Turkish-specific rules like 'de/da' and 'ki' exactly where most foreign tools miss them.

Remember: Ryna is a correction assistant, not a replacement for a human proofreader. The output is a draft — especially for proper nouns, technical terms, and deliberate stylistic choices, the final call is yours. On the free plan, near-unlimited daily messages let you check as much text as you want, from a short email to a long report. If you want to upload a full Word/PDF document to check as a whole, or verify the spelling of text inside an image (say, a scanned page), Plus (399.99 TRY/mo) unlocks file and image analysis. For the bulk of everyday writing, the free plan is more than enough.

Why use Ryna AI for this

Doesn't just fix — teaches: for each error a 'wrong → right → why' triad, so you don't repeat the same pattern.

Catches Turkish-specific traps: 'de/da' separate vs joined, the 'ki' conjunction vs '-ki' suffix, apostrophes, 'herkes/herkez' — spots most foreign tools miss.

Reads context: it judges the whole text's tone and audience, not isolated sentences; it won't edit a formal petition like a social caption.

Two outputs: an annotated error list plus, on request, a clean corrected version you can copy straight out.

Not just grammar but naturalness: especially in English, it flags 'technically correct but sounds off to a native' phrasings.

Near-unlimited checking on free: from a short email to a long report, review as much text as you want daily.

>Check this text. Flag each error one by one, give the correction, and briefly explain why it's wrong. At the end, provide a clean corrected version separately: [text]
>In the text below, look only at comma splices, apostrophes, and subject-verb agreement. Don't touch anything else or change my style: [text]
>Check this English email. Flag both grammar errors and phrasings that sound unnatural to a native speaker, and explain each change: [text]
>Are there spelling or punctuation errors in this formal letter? Keep the formal tone, only fix errors, don't rewrite the content: [text]
>Which is correct and why: 'Me and my friend went' or 'My friend and I went'? Explain the rule with examples.
>Give the errors in this paragraph as a table with columns 'Wrong | Correct | Rule'. Text: [text]

How it works — step by step

  1. 1

    Paste the text and state the language

    Go to chat.rynaai.com and paste the text you want checked. Say briefly what it is: 'formal Turkish email' or 'English CV summary'. Once the language and type are clear, Ryna knows which rule set to apply.

  2. 2

    Say what you want: fix + explain

    Don't just say 'check it'; say 'flag each error, give the correction, and explain why it's wrong'. Want to learn? Ask for explanations. Want only clean text? Say 'give me only the corrected version'.

  3. 3

    Set boundaries: what to touch, what not to

    To preserve your voice, say 'don't change meaning or tone, only grammar and spelling'. To focus, narrow it: 'punctuation only' or 'only subject-verb agreement' — that way no unwanted rewrites creep in.

Example: input → output

You ask

Check this text, explain each error, then give the clean version: 'Dear Sir, I am writing to enquire about my application. Me and my colleague has submitted the same form last week, and I attached it in the mail. Thank you in advance for you’re help.'

Ryna AI returns

I found 4 issues. Here they are one by one: 1) 'Me and my colleague' → 'My colleague and I' Why: As the subject of the sentence you need the subject pronoun 'I', not 'me'. Convention also puts the other person first: 'My colleague and I'. Test it by removing the other person — you'd say 'I submitted', not 'me submitted'. 2) 'has submitted' → 'submitted' (and agreement) Why: The subject is plural ('My colleague and I'), so the verb would be 'have', not 'has'. But since you have a specific past time ('last week'), simple past 'submitted' is the natural choice, not present perfect. 3) 'in the mail' → 'to this email' / 'in the attachment' Why: 'in the mail' suggests postal mail. For an email attachment, 'I have attached it to this email' or 'please find it attached' reads naturally to a native. 4) 'you’re help' → 'your help' Why: 'you’re' = 'you are'. Here you need the possessive 'your'. A classic homophone slip. Clean corrected version: 'Dear Sir or Madam, I am writing to enquire about my application. My colleague and I submitted the same form last week, and I have attached it to this email. Thank you in advance for your help.' Note: I kept the formal tone. I also changed 'Dear Sir' to 'Dear Sir or Madam' since you don't know the recipient's gender — revert if you know it's a man.

Pro tips

  • Don't paste a long text all at once; tell Ryna 'go paragraph by paragraph, show each paragraph's errors separately'. No error gets lost between blocks and you approve fixes in order.
  • Ask for errors as a table: 'Wrong | Correct | Rule' three columns. You'll see how many times you break the same rule and spot the root habit.
  • Interrogate tone, not just grammar: add 'this sentence is correct, but is it too formal/casual?'. Ryna goes past the error to assess register fit.
  • For a recurring mistake, ask for a 'mini rule card': 'summarize the comma-splice rule in 3 examples'. You won't fall into the same trap next time.
  • Preserve deliberate style: for poetry, slogans, or social copy, add 'don't apply rules strictly, don't break the voice' — otherwise it 'fixes' creative inversions.
  • For English, say 'flag not just errors but unnatural-to-native phrasings'. Most issues aren't technical — they're 'thinking in Turkish, writing in English' naturalness problems.

Common mistakes to avoid

  • Saying only 'check it' without asking for explanations — it fixes the error but you don't learn why, so you repeat it in the next text.
  • Publishing the clean version without a final read. Ryna may treat a proper noun, brand name, or technical term as an 'error' and change it; the output is a draft, review it.
  • Pasting a long text without boundaries: if you don't say 'preserve meaning, grammar only', Ryna may rewrite sentences and your voice disappears.
  • Letting it 'fix' deliberate style (poetry, slogans, inversions) as errors. In creative text, if you don't say 'don't apply rules strictly', the voice flattens.
  • Treating Ryna as the single authority: for disputed punctuation or newly coined words, confirm with a trusted reference — it can occasionally be wrong.

FAQ

Does it really catch Turkish 'de/da' and 'ki' errors?

Yes — these are among Ryna's strongest areas. Being built Turkish-first, it distinguishes the separate-written 'de/da' from the joined '-de/-da' suffix, and the 'ki' conjunction from the '-ki' suffix, explaining the rule behind each. For very disputed cases, confirming with the official authority (TDK) is still wise.

How is it different from Grammarly?

Grammarly flags fast and inline; Ryna is contextual and explanatory. Grammarly judges each sentence in isolation, while Ryna weighs the text's tone and audience, explains why each fix applies, and is far stronger in Turkish. Grammarly is more practical for instant, in-line checking.

Can I trust the output 100% and send it directly?

No — Ryna is a correction assistant, not a replacement for a human editor. The output is a reliable draft, but for proper nouns, technical terms, and deliberate stylistic choices you should do the final read. Review once before publishing.

Is it ethical to use for academic homework/theses?

Spelling and grammar correction is accepted at most institutions; but having Ryna write the content can count as plagiarism. Check your institution's AI and editing policy, and mind the line between fixing the language of your own sentences and generating the text. The responsibility is yours.

Can I check a long document (Word/PDF) as a whole?

You can check short texts by pasting them on the free plan. To upload a whole file (Word/PDF), or verify the spelling of text inside an image, Plus (399.99 TRY/mo) unlocks file and image analysis.
