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.
Cursor for email analogy is perfect! I love the focus on personalisation, we are actually building a personalised product ourselves, so I'm a believer that personalisation is king in this space. How does Lightfern handle the balance between using past thread context and the user’s global writing style? Does it prioritize recent interactions, or does it build a long-term tone of voice profile?

@valeriia_kuna Thanks Anna for the kind words! I agree - personalisation is important.
We have mechanisms to balance past thread context with the user’s global writing style. Both approaches are valid; what matters is having the most accurate, up-to-date version of the user’s style and feeding it to the AI at the right time. Context engineering is central to our product, and we’re focused on making it correct and reliable for our users.
Can't wait to see what you've been working on 👀 Fingers crossed for your product!
@gastlich Thanks for the insights, Jacek! (It’s Valeria, by the way, but no worries :) ). I love the term context engineering—it really captures the complexity of what we are all trying to achieve with personalization right now!
Fingers crossed for Lightfern's growth! Looking forward to seeing how you guys evolve this further!

@valeriia_kuna Sorry Valeriia for the mistake. It won't happen again :)
Congrats on the launch! Positioning this as Cursor for email with deep thread context and personal tone is compelling. How does Lightfern balance pulling in rich historical context with avoiding overreach, especially so suggestions feel helpful and accurate without surfacing details that might no longer be relevant or appropriate in a given conversation?

Interesting project. Why don’t you save the data? Is it because of GDPR?

@mykyta_semenov_ Great question! That's more of our philosophy on security and privacy: we don't want to have access to people's personal data more than we need to.
