SMS filter checker

Tab.it is built around a privacy-first principle — non-financial messages never leave your device. Every SMS passes through multiple on-device filters before it can become an expense, so personal messages, OTPs and promotions are discarded on your phone and never reach our servers.

Test a message

Paste an SMS below and press Check to see how Tab.it's on-device filters would handle it. Nothing is uploaded — the check runs entirely in your browser.

29 keywords across 5 categories. If an SMS contains any of these (case-insensitive substring match), it is blocked on your device and never sent to Tab.it's servers.
