Hi! We’re Lightfern.
We have a simple thesis: communication is about both conveying a message and building human connection between individuals. Most AI writing tools misunderstand this and solely optimise for the first point. The result is the erosion of people’s authentic voices across all platforms.
Lightfern adapts your voice for any situation, with two flagship features.
- Ultracomplete works using the world’s best autocomplete model, trained in-house.
- Inline Composer allows you to query, re-write, and edit from the comfort of your draft.
Both features nail greetings, sign-offs, nicknames, and even facts from three months ago, using context from previous emails to understand your needs and your voice. Together, they’re wrapped in a sleekly designed product with great UX.
Don’t take our word for it - users call Lightfern “the closest thing to telepathy I’ve experienced with an AI tool.” GTM teams at companies like ElevenLabs and leading founders rely on it daily. User retention is strong and we’re already building a cult following.
Email is just the beginning. Lightfern is redefining an entire category. We want to be in every communication layer, bridging contexts and amplifying people’s individuality and voice.
We have the team to do it – we come from OpenAI, Imperial College London, Attio, OakNorth Bank, ex-YC startups. Now we need a cracked person to spread awareness and get millions of people using us.
