Lightfern Ai Email

Working directly in your inbox as a browser extension,
Lightfern nails the details that make emails feel like you - nicknames, sign-offs, your tone of
voice - and pulls context from past threads to finish sentences the way you would. All with Zero
Data Retention by default.

Build stronger relationships. Lightfern keeps you thoughtful, whether it's remembering your VC's ski
trip to Switzerland or a long-forgotten invoice number. Pull information without the deep-dive.

Redraft and edit without leaving the page. Lightfern sees what you see, so you can edit and redraft
without leaving your inbox.

Code-switch between private and professional inboxes. Add multiple emails to a single Lightfern
account and still enjoy full personalisation, based on your current context.

=== How to use Lightfern ===

Press tab to accept whole Ultracomplete suggestions or → to accept a single word. Keep typing to

Ctrl+Cmd+L.

=== Privacy and security ===

Lightfern is built with security at its centre. This means Zero Data Retention by default.

Unless you explicitly opt-in to sharing your data with us for training, your email data is only used
for transient processing to provide AI suggestions; we do not retain any copies on disk and do not
train on your data. By default, processing data is only held in volatile memory and automatically
purged within minutes.

Access tokens (such as your Google login) also stay only on your machine and Lightfern's servers
cannot fetch them.
