MessageCat

MessageCat uses AI to intercept spam texts with one-click activation. It automatically classifies messages into normal, spam, promotional, and transactional categories, and offers both real-time online protection and offline local filtering to protect your privacy.

You can customize rules with keywords and numbers, block all SMS or verification codes, and share feedback to improve accuracy. MessageCat emphasizes privacy, with local processing whenever possible, and easy ways to contact support.
