Grammar & Spelling Checker
Paste your text to catch spelling, grammar, punctuation, and style issues. Get a corrected version alongside a clear explanation of every change. Recent checks remain stored locally in this browser.
Grammar & Spelling Checker
- Your text is transmitted to our server and analyzed via an AI provider. We do not intentionally retain submitted text in application database storage.
- AI suggestions can occasionally misinterpret context or alter tone—always review proposed edits before publishing.
- Free usage is shared: up to 20 checks per IP per hour and 500 checks per day across all users. You may optionally supply your own API key if server quotas are exhausted.
How It Works
Paste, analyze, and review — a fast workflow for cleaner writing.

Paste up to 5,000 characters and choose your language.
Analyze
The AI scans for spelling, grammar, punctuation, and style issues.

Before You Publish
AI proofreading provides a secondary check, not an infallible editorial guarantee.
Voice
The AI may rephrase sentences for clarity. Read the corrected text aloud to ensure it still sounds like you.
Context
Industry jargon, creative phrasing, or deliberate stylistic choices can be flagged as errors. Trust your domain knowledge.
Critical docs
For legal, academic, or medical documents, always have a qualified human review the final text.

Troubleshooting
Quick fixes for common issues.
AI changed my meaning
Style suggestions occasionally rephrase sentences. Compare the corrected text to your original and reject any change that alters your intent.
"Quota" or "limit" error
Free server quota (20 checks/IP/hour, 500 checks/day global) is exhausted. You can wait for the reset or continue using your own Gemini or OpenRouter key via the popup.
Non-English output feels awkward
Model fluency varies by language. Treat Hindi, Gujarati, Spanish, French, and German output as drafts to polish.
History disappeared
History lives in this browser's localStorage. Private windows, cleared site data, or a different device will show an empty list.
Frequently Asked Questions
Common questions about the Grammar & Spelling Checker.
How do the explanations work?
The AI returns a bulleted list categorizing each change as [Spelling], [Grammar], [Punctuation], or [Style], showing the original phrase, the corrected phrase, and a short reason. Treat these as suggestions — the AI can occasionally misinterpret context or intent.
Is my text sent to a server?
Yes. Your text is sent to the AllInOneTools server and then to an AI provider for analysis. This tool does not intentionally save submitted text in application database storage, though standard infrastructure and provider transit logging may apply. Recent history is saved only in this browser's localStorage.
How accurate is the grammar checker?
The tool is designed to catch common spelling, grammar, and punctuation mistakes, but it can miss subtle context issues or suggest changes that alter your tone. Always conduct a final human review for critical documents.
Does the tool rewrite my text?
The AI attempts to preserve your meaning and voice while fixing errors, but 'Style' suggestions may occasionally rephrase sentences for clarity. Review the corrected text to ensure it still sounds like you.
What happens if I hit the free limit?
The free quota is 20 checks per IP per hour and 500 checks per day across all users. If these quotas are exhausted, you can continue immediately by entering your own Gemini or OpenRouter API key, which communicates directly from your browser.
Can I check text in languages other than English?
The tool supports English, Spanish, French, German, Hindi, and Gujarati. Accuracy varies by language — non-English output should be reviewed carefully by a fluent speaker.
