A free spam-filtering app for Mac
Klar is a free AI-powered spam filter for Apple Mail that helps users identify unwanted emails. This tool runs directly on a Mac without uploading email content to the cloud and detects phishing attempts, scams, and junk messages that the built-in mail filter may miss.
Flexible spam detection
With Klar, you can check incoming emails through a mail extension. During the first 30 days, it flags suspected spam in red without moving messages out of the inbox. After that, it can automatically move spam to junk. You can change this setting whenever you prefer.
More importantly, the app processes emails locally without internet access, an account, or automatic data collection. It supports multiple languages, an optional contacts whitelist, and a dashboard for tracking detected spam. You can also review an editable usage report before sending it. However, it is limited to Apple Mail on Mac.
Privacy-focused email protection
Klar offers a practical way to manage unwanted emails while keeping personal data on your Mac. The spam detection, multilingual support, and privacy-focused design make it useful for Apple Mail users. However, its limited compatibility means users of other email apps or operating systems need another solution.
