I built ReplyFast an AI powered tool to write faster and better emails

Hacker News

Hi Hacker News I’m a solo developer passionate about productivity. Over the past few months, I built ReplyFast, an AI powered email assistant that helps you draft replies, generate ideas, and improve your writing in seconds Unlike generic writing tools, ReplyFast focuses on speeding up email responses by suggesting concise and relevant answers tailored to your context. It supports multiple languages and lets you easily customize tone and style I created this tool because I often spent too much time stuck on email replies and wanted a simple yet powerful assistant to speed up the process without losing personalization I’d love your feedback on the tool — what works, what can be improved, or any feature ideas. Feel free to try it out and let me know what you think Thanks [Tom]
