## Description

Lightfern is an AI-powered email writing assistant designed to help people communicate naturally and confidently. Its autocomplete model draws on the user’s writing style, previous conversations, and the context of the current email thread to suggest relevant replies and complete thoughts. Whether composing a brief response or handling a more difficult conversation, users can draft full replies, adjust tone, and ask questions about a thread without leaving their inbox.

Lightfern is available for Gmail, Outlook Web, and Superhuman Web, and is set up by installing its extension and connecting an email account. The service highlights inbox-wide context, helping users recall details about contacts and past discussions to make follow-ups more personal. Lightfern says emails are not used to train models by default; users must explicitly opt in for that use. The company also describes its technology as built in Europe. Lightfern serves a range of professionals, including founders, sales leaders, account executives, product managers, and investors, and offers free sign-up.
