What is Klar?
Apple Mail's junk filter misses a lot, especially AI-written scams and phishing. The filters that don't miss (Gmail, cloud gateways) read every message you receive on somebody else's server.
Klar is the third option. It runs a real multilingual model (XLM-RoBERTa, 550M parameters) on your Mac: every message is classified in 13 to 44 ms on Apple Silicon, across 100+ languages, and spam is moved to Junk automatically. The part of Klar that reads your inbox has no network entitlement, so by construction it cannot send your mail anywhere. No account, no cloud, no telemetry.
Turn on Trust my contacts to keep verified mail from people you know in your Inbox, and choose among three sensitivity profiles (Cautious, Standard, Aggressive) to set the balance between catching spam and protecting real mail.
Free on the Mac App Store. macOS 14+, Apple Silicon. Built in the EU.
