Loved by writers everywhere
“Rendraft has completely changed how I write prompts. My ChatGPT outputs improved overnight. The floating button is so unobtrusive I forget it's there until I need it.”
“The grammar fixer catches all my typos without making my writing sound robotic. Works perfectly on Slack, GitHub comments, anywhere.”
“Works seamlessly on every AI platform I use. No more switching tabs to fix my prompts. The custom rewrite feature is incredibly flexible.”
“I use it in Gmail every single day. Drafting emails used to take me 10 minutes. Now I jot down the key points and Rendraft formats it professionally in seconds.”
“The diff view is brilliant — you can see exactly what changed before accepting. That level of transparency is rare in AI tools.”
“Finally a tool that doesn't get in the way. It sits quietly beside every text field and appears exactly when I need it.”
