Frequently asked questions
How accurate is MyToolsBag's grammar checker?
It combines a rule-based grammar engine with modern language models to catch typos, punctuation, agreement and style issues at high accuracy.
Is my writing sent to a server?
Yes, text is sent to the language model to produce corrections. It is not stored by MyToolsBag.
Do I need to sign up?
No. MyToolsBag's Grammar Checker is completely free and requires no account.
Which English variants are supported?
US, UK and Australian English. Pick your target variant so the checker applies the right spelling (color vs colour) and punctuation conventions.
Does it explain each correction?
Yes. Hover any highlighted issue to see a short explanation — subject-verb agreement, comma splice, redundant word — so you learn while you edit.
How does it compare to Grammarly?
MyToolsBag covers the same core categories — grammar, spelling, punctuation and style — with no signup, no browser extension and no upsell. Grammarly's premium adds team features and plagiarism, which are out of scope here.
Is there a length limit?
About 20,000 characters per check. For longer documents, break your text into chapters or sections.
Can I use it for academic writing?
Yes. Pick the Formal tone and the checker becomes stricter with contractions, first-person voice and hedging language, matching typical journal and thesis expectations.
