TextKiller is an iPhone application developed by TelTech Systems Inc. It is a text-blocking app that eliminates 95% of spam text messages with its AI-powered Smart Blocking technology. Its filtering system uses machine learning to detect and filter out unwanted spam text messages. The app also offers automatic protection, so there is no need for any complicated setup or configuration.

TextKiller allows you to customize your protection with powerful block and allow lists for both numbers and keywords. You can filter all messages outside of your contacts and choose who can and can't text you. The app promises to never block iMessages or text messages from your contacts. If a text message isn't from a contact, TextKiller's advanced protection will filter out any spam messages to your Messages "Junk" folder and leave the legitimate ones in the inbox.

TextKiller is free and powered by RoboKiller, which has been featured on The New York Times, NBC, Wired, Engadget, Vice, and other publications. TextKiller is built by people who hate robocalls, spam texts, and respect your privacy. They promise to never sell your data, spam you, or waste your time. Their mission is to stop spam text messages forever, or die trying!
