Shruti KaushikGrammarly is the stronger choice if you want correctness, tone help and AI assistance in everything you write, everywhere you write it. Klype AI is the stronger choice if your problem is LinkedIn posts specifically: drafts built from your product, buyer and measured voice, and a check for unsupported figures, invented stories and the patterns readers associate with AI writing. They overlap less than it looks.

What each tool is for
Grammarly fixes and improves writing wherever you type. The free plan covers mistakes, shows your tone and includes 100 AI prompts a month. Pro adds tone adjustment, a brand tone, a style guide, AI-text detection, plagiarism checks and 2,000 prompts a month.
Klype is built for one job: LinkedIn posts that sell for a B2B founder. It holds your product, buyer and measured voice in one record and drafts and checks against it.
Voice and checks
Grammarly's brand tone and style guide let you describe how you want to sound and apply rules. Its AI detector estimates whether text looks machine-written.
Klype measures how you already write from your own posts and holds drafts to those numbers. Its Check looks for problems specific to LinkedIn posts: figures with no source, stories that did not happen and machine-writing patterns such as flat rhythm and stock openers. A draft can be grammatically perfect and still fail these. Try it free at klype.ai/check.
Publishing and safety
Neither tool posts to LinkedIn for you. Grammarly works inside the editors you already use. Klype gives you a checked draft to publish yourself.
Price, trial and what you get
Grammarly Pro costs $12 a member a month billed yearly ($144), $60 a quarter or $30 billed monthly, with a free plan and a 7-day Pro trial.
Klype costs $39 a month, $99 a quarter or $299 a year, with a 7-day free trial and no card. Klype launched publicly on 1 October 2026, so its track record is short and you should weigh that honestly.
