Frequently asked questions
- Is AI matching slower than keyword matching?
- Each post takes a moment longer to judge, but alerts still arrive shortly after posting, and you skip reading the false positives yourself.
- Can BuzzGlean do exact keyword matching too?
- Yes. Keywords narrow the stream first; the AI description then filters by meaning. Use a broad description if you mostly want keyword hits.
