Lightfern is an AI-powered email tool that provides blazing fast autocomplete functionality designed to write emails in your personal style. It operates as a browser extension that works directly within your email inbox, requiring no additional configuration after installation.
Lightfern nails greetings, signoffs, nicknames, and tone to ensure emails feel authentic to your voice. The tool pulls context from past email threads to finish sentences the way you would naturally write them. It features Ultracomplete, which is described as the world's best autocomplete model in terms of context awareness and speed.
The product uses world-class technology proudly built in Europe and offers zero data retention by default, meaning your emails are never used for model training unless you explicitly opt in. Lightfern sees what you see in your email interface, allowing you to redraft and edit content without having to copy-paste across different tabs and language models.
Lightfern helps build stronger relationships by keeping you thoughtful and remembering important details from previous communications, whether it's recalling someone's vacation plans or specific reference numbers. This enables more personalized and effective email communication.
The tool is designed for professionals who want to streamline their email workflow while maintaining their authentic voice. It integrates directly with email platforms through a browser extension and focuses on enhancing productivity for users who rely heavily on email communication.
