What it does

Finish thoughts before fingers hit keys. 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.

Your voice, for any email. Powered by the world's best autocomplete model.

From a two-line reply to a difficult conversation, Lightfern adapts to any situation. Now available in Gmail , Outlook Web , and Superhuman Web Thanks for sending over, Nadia. The narrative is much stronger this time. → The Q3 revenue figure on slide 4, is that recognized or contracted? → Can you add a slide on competitive positioning? The other board members have been asking. The Q3 figure on slide 4 is recognized revenue, not contracted. I'll add a footnote to clarify. Meridian Health signed last week. I'll update the partnership slide with the latest numbers. Adding a competitive positioning slide now. Will have the updated deck to you by Wednesday. Great chatting at Web Summit!

  • Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
