TextSieve vs Sift

TextSieve helps you filter spam, scam, and unwanted text messages with private, customizable rules that run on your iPhone. Your messages stay on your device. TextSieve does not collect personal information, does not upload SMS content, does not require an account, does not show ads, and does not use advertising or tracking SDKs. Built for common U.S. text spam and scam patterns, TextSieve includes local rules for package delivery scams, unpaid toll notices, bank phishing alerts, verification-code phishing, utility shutoff scams, suspicious links, investment scams, adult spam, political texts, and marketing messages. Customize your protection: - Turn filtering categories on or off - Add trusted senders to an allow list - Block unwanted senders - Add keywords that should always be allowed - Add keywords that should be filtered - Test sample messages locally before changing your setup - Import and export your rules as a local JSON backup - Reset to the built-in rule set at any time TextSieve is designed for people who want control without giving up privacy. Rules are stored locally, filtering happens locally, and your message content is not sent to a server. To enable SMS filtering, install TextSieve, then open iPhone Settings > Apps > Messages > Unknown & Spam. Turn on Filter Unknown Senders and select TextSieve as your SMS filter. Filtering depends on your rules and iOS message filtering behavior. Always review important messages carefully before taking action.

Sift is a privacy-first SMS filtering app for iPhone, built to make your inbox quieter and easier to control. Sift uses the iOS message filtering extension to classify junk, promotions, and important notifications directly on your device. By default, filtering does not send message contents to a server. Your custom rules, local statistics, and on-device personalization stay on the device. Key features - On-device SMS classification for spam, promotions, verification codes, delivery updates, banking notices, travel alerts, and more - Custom sender or message-body rules - Category mapping that redirects selected categories to Promotions or Junk - Private statistics that count categories without storing message text - Optional sample contribution with an on-device redaction preview, export, and deletion controls - Sift Premium: a one-time purchase that unlocks an on-demand multilingual Transformer model Sift is not a fraud-prevention guarantee. SMS classification is probabilistic and can make mistakes. For payments, accounts, verification codes, or other important messages, always verify the original message and official channels.
