About
Hi, I’m Jacek - Founding Engineer at Lightfern 👋 We’re building AI-powered email writing that keeps you in control. Lightfern learns how you write from real email context and helps you respond faster, without losing nuance, tone, or authenticity. My favourite part? It’s always there when you’re stuck - whether that’s wording something delicately, simplifying an over-complicated sentence, or just getting unstuck and moving on with your day. We care deeply about privacy, human creativity, and building tools that support people rather than replace them. Happy to answer any technical questions - fire away!
