Fix grammar, rewrite tone, translate, and summarize without leaving your app. Penna is a Mac menu bar AI writing tool triggered by a single keyboard shortcut.
I was tired of constantly opening ChatGPT for every small sentence during my workday just to fix grammar or tweak the tone. So I built Penna to solve that right where I’m typing.
The idea is simple: fix your grammar easily in any app or ask AI anything, instantly. I kept the focus on speed and making it feel effortless.
You can try the free plan, and it would be amazing to hear your feedback 🙌
