Use it every day

Honestly didn't expect to like it this much. Integrations with Word, Google Docs, Gmail, and more is exactly what I needed, and works across many apps, browsers, and devices. I do wish advanced suggestions require a paid plan, but I reach for it almost every day now and it just clicks.

Does the job

Pretty happy overall. Clarity, conciseness, and tone suggestions just works and team and brand voice features for businesses. Primarily optimized for English can be annoying, but no dealbreakers — I'd recommend it to a friend without hesitating.

Years in this space

I've evaluated a lot of these over the years. What stands out here is aI-powered drafting and rewriting — handled better than most — and useful free tier for basic checks. Worth the time if this is your use case.

Solid for our team

We rolled this out across the team last quarter and works across many apps, browsers, and devices. Plagiarism detection (premium) fits neatly into how we already work, and aI-powered drafting and rewriting removed a step we used to do by hand. but it has held up under daily use.
