Why I built Wandpen
I used to use ChatGPT a lot to fix my emails and articles.
I will copy my writing and paste it into ChatGPT and ask it to improve it or fix grammar errors and so.
But I noticed something: I was constantly copy-pasting between sites.
It worked — but it was clunky.
So I built Wandpen. A tool that brings the power of ChatGPT directly into wherever I’m writing.
I loved building it. I loved using it.
I hope you enjoy using it.
Cheers,
