Where it fits. Proofreading blog posts, articles, and web copy before publishing; keeping emails and customer messages professional; checking ad and social copy for tone; and holding a consistent brand voice across written communication.
Pricing. A capable free tier covers grammar, spelling, and punctuation. Premium and Business tiers add style, tone, clarity, and plagiarism checks; Premium typically starts around $12/month billed annually. Confirm current pricing on the site.
Practical notes. Treat it as a safety net, not an oracle — apply judgment on stylistic suggestions rather than accepting all of them. The tone detector is genuinely useful for matching intent, and goal-setting tailors suggestions. The free tier is valuable; Premium meaningfully raises the ceiling for professional work. It pairs well with a readability editor like Hemingway, which targets different problems.
