Notification history

FilterBox saves every notification the moment it arrives, so you can come back to it later:

Search by app, keyword, notification type (media, chat, picture, persistent, silent), custom rule, AI result or how it was dismissed.
Scroll the timeline to jump to any hour or day.
Restore notifications you dismissed by accident, and read messages that the sender later deleted or recalled, as long as they appeared in a notification.
Export the history to CSV for Excel, Google Sheets or WPS.

The history is stored encrypted on the phone. Free users keep recent history; Pro keeps it for much longer.

Offline AI spam filter

An on-device machine-learning model gives each notification a spam score. Notifications at or above the threshold (80% by default) are filtered. Open any notification and tap It is spam or It is normal to teach it; FilterBox learns from your feedback while the phone is idle or charging. You can choose which apps the AI covers, and media controls, chats (other than SMS) and persistent notifications are left alone by default. The AI runs entirely offline. It requires Android 10 or later and, on newer installs, a phone with more than 6 GB of RAM.

Custom rules

A rule matches notifications by:

Apps — include or exclude specific apps
Keywords — contains any or all of some text, does not contain, “contains A but not B”, a regular expression, or an advanced JSON rule on any notification field
Time and date — time ranges, weekdays or weekends
Phone state — screen on or off, charging or on battery

…and then performs one or more actions:

Action	What it does
Dismiss	Removes the notification from the status bar (optionally after a delay, including persistent notifications on Android 8.0+)
Mute	Silences the notification
Snooze	Hides it until a time you choose
Replace	Rewrites the title and text with a template, to hide sensitive content
Change sound	Plays a custom ringtone (Android 10+)
Read out	Speaks the notification with text-to-speech
Call style notify	Re-posts it as a full-screen, ringing alert like an incoming call
Tap button	Taps an action button such as “Mark as read” or “Archive”
Open	Opens the notification automatically
Webhook	Sends the content as JSON to a URL (guide)

Rules can be tested against your history before saving, imported and exported as JSON, and shared. Recommended rules and community rules help you get started.

Enhancers

Dismissal Recall — shows an Undo button for 5 seconds after you swipe a notification away.
Smart Shh — mutes an app that sends too many notifications in a short time (for example, 3 within a minute while the phone is unlocked).
Verification code copy — adds a Copy button to verification codes in SMS and other apps, with optional auto-copy and hiding on the lock screen.
Webhook — forwards matching notifications to your own server, chat bot or automation.

Analytics and more

Recent and daily charts show which apps send the most notifications and how many were filtered. FilterBox also offers home screen widgets, fingerprint and face lock, themes that follow the system or the time of day, exclusions, and backup of rules.
