Why I built Wandpen
I used to use ChatGPT a lot to fix my emails and articles.
I would copy my writing and paste it into ChatGPT and ask it to improve it, rewrite it, or fix grammar errors and so.It worked.
But I am constantly changing tabs and disturbing my workflow.
I wanted something that does this natively where I write just like Grammarly but without constant red squiggly lines and popups.
So I built Wandpen. A tool that combines the power of ChatGPT & Grammarly directly into wherever I'm writing.
I loved building it. I loved using it.
I hope you enjoy using it as well.
Cheers,
