AI Spam filter for Apple Mail

AI spam filter for Apple Mail. Runs locally on your Mac. Private by design.

Top comment

Hi Product Hunt! I'm Nicolas, the maker of Klar.

I've 10+ years building messaging infrastructure and security systems. I want to build something obviously good. A force for good. I built Klar for Apple Mail users who want a modern filter without sending messages to a third party to filter spam.

In practice that means:
- A multilingual AI model that runs entirely on your Mac
- Works with any account you read in Apple Mail, no account limitations
- Flags or moves spam to Junk
- No account and no automatic telemetry. The Mail extension has no network access.
- Free on the Mac App Store
- The engine is open source (Github)

A paid extension app is coming too to allow the AI model to learn overnight from your inbox.

I value all feedback. These are early days and questions and suggestions are make-or-break for me.

I will be here to answer questions. Be warned that this is just me and I don't use AI for this so replies might take a while :)
