AI Meeting Notes & Transcripts
Record conversations, generate summaries and action items, then send follow-ups without rewriting the meeting.
Advanced Grammar Correction
The AI flags subject-verb agreement, wrong tense shifts, dangling modifiers, article use, and preposition slips that autocorrect often ignores. Each suggestion targets the sentence you wrote, not a generic rule list, so academic paragraphs and technical memos both get sensible fixes.
Spelling & Punctuation Checker
Catch homophones (their/there), inconsistent capitalization in headings, missing Oxford commas where style matters, and stray apostrophes before you attach a file or hit send. Helpful when you are finishing a resume, a newsletter, or a contract summary under time pressure.
Improve Clarity & Readability
Long sentences and repeated words make even correct grammar hard to read. The checker suggests tighter phrasing and smoother flow while keeping your meaning — ideal for blog intros, executive summaries, and cover letters where the first impression is the wording.

FAQ
AI Grammar Checker FAQs
Answers about free use, essays, emails, business writing, accuracy, and how this tool fits with Knowant Writer.
An AI grammar checker analyzes your writing for grammar, spelling, punctuation, and often clarity problems, then suggests corrections. Knowant’s version runs online so you can check a paragraph or a multi-page draft without installing software. It is a editing aid: you review each change before using the text in school, work, or publication.
Yes. You can run grammar and spelling checks on this page without paying to start. Free access is meant for everyday proofreading — essays due tonight, emails before a meeting, a quick pass on a report. If you need ongoing projects, saved drafts, and more Writer tools, you can sign up and explore Knowant Writer separately.
Many students use it for essays, research summaries, and discussion posts to catch errors before submission. Follow your institution’s rules on AI assistance: some courses allow grammar help but not generative rewriting. Use suggestions to improve your own sentences, and always cite sources you quote — the checker does not replace academic integrity policies.
Yes. It helps with client emails, project updates, HR policies, proposals, and slide deck copy where typos undermine credibility. Business writing often needs a consistent tone; accept suggestions that match your brand voice and leave informal fixes for internal chat only.
Good suggestions preserve intent while fixing errors or tightening wording. You choose what to apply, so legal disclaimers, product names, and deliberate casual tone stay intact. If a rewrite feels off, reject it or rephrase manually — or use Knowant Writer for controlled tone and length changes.
Built-in checkers excel at obvious typos. AI grammar tools also weigh sentence structure, agreement, punctuation patterns, and sometimes readability across longer passages. Use both: your editor’s spell check for quick typing, and Knowant when the draft is important or dense.
This page is optimized for a fast, free grammar pass. Knowant Writer (https://www.knowant.com/product/write-with-ai) is the fuller workspace for drafting, paraphrasing, summarizing, and refining longer content. Many users check grammar here, then move the polished text into Writer when they need to develop ideas or collaborate on a document.
Treat sensitive data (passwords, personal IDs, unreleased financials) like any cloud tool: avoid pasting secrets. For routine essays and business copy, paste what you would normally send to an editor. Check Knowant’s privacy policy for how data is handled, and use your organization’s guidelines for confidential material.
