Monitoring a busy account without filters quickly turns into noise. Tweet Catcher lets you decide which posts deserve an alert and which should be ignored.

Use simple keyword rules to include or exclude certain terms, or switch to regex when you need to match a pattern such as a contract address. Filters are set per account, so each monitor can follow a different set of rules.

Follow alerts can be filtered too, making it possible to focus on accounts that fit the size or activity you care about.

## Capabilities

Full regex (regular expression) support for complex patterns

Keyword inclusion and exclusion filters

Case-sensitive and case-insensitive matching

## Frequently Asked Questions

### Can I use regex to match contract addresses?

### Can I use keywords and regex on the same task?

No. Each task uses either keyword filters or regex.

### Can I filter follow alerts?

Yes. You can filter them by the followed account's follower, following, and post counts.

### Do filters work with Telegram alerts?

Yes. Keywords can decide which Telegram alerts make a sound and which posts are left out entirely.
