Spam Rule AI
Read full descriptionHide full description
Spam Rule AI checks a suspicious text or voicemail for scams, then helps you block the number. Paste the message or a voicemail transcript. Spam Rule AI tells you if it looks like a scam, what kind, and which phone numbers are in it. The check runs on your iPhone. Your text doesn't leave it. WHAT YOU GET - Scam check. Paste a text or a voicemail transcript. It names the type: fake toll bill, fake delivery notice, fake bank alert, tech support, prize, car warranty, family emergency, code theft and more. - You approve every number. Bad-looking numbers are pre-selected. Untick any of them. Nothing is blocked until you tap Block. - Call blocking. Spam Rule AI blocks the numbers on your list through iPhone's Call Blocking & Identification. Label Only mode lets the call ring and labels it "Possible spam" with your note. - Text filtering. Texts from unknown senders go to the Junk folder in Messages when the sender is a number you blocked, the text has one of your junk words, or it's high risk with a hard sign: an odd link, a gift card or wire ask, or a request for private details. Nothing is deleted. - Block list tools. Search, edit a label or note, add numbers by hand, import from a file, export as CSV. Undo an add, import or removal for 6 seconds. - On-device AI. It uses Apple's on-device model on iPhones that support it, and built-in rules on the rest. FREE AND PRO Free gets 3 AI checks a day and 10 blocked numbers. Rule checks and text filtering are always free. Spam Rule AI Pro is a monthly subscription with no limit on AI checks or blocked numbers. Billed through your Apple ID. It renews automatically until you cancel in your Apple ID settings. WHAT IT DOESN'T DO - It isn't perfect. It can miss a scam or flag a real message. Treat the result as a second opinion. - It can't block a number you haven't added. - You turn on call blocking and text filtering yourself in iPhone Settings. The app shows you where. iPhone doesn't tell apps whether text filtering is on, so check Messages if you're not sure.
