AI search-term hygiene for Google Ads
Keep the grain.
Cut the chaff.
Chaff reads your account, learns what you actually sell, and negates the search terms quietly draining your budget — so every pound chases a real customer.

Built for performance teams who hate wasted spend
How it works
Winnowing, on autopilot
Three quiet steps between you and a leaner account.
Learn your business
Chaff reads your account, landing pages and offering to understand what you actually sell — and who you sell it to.
Score every term
Each search term is judged on intent and relevance to your business, not just clicks and cost. The chaff rises to the top.
Negate the waste
Irrelevant terms are added as negative keywords — automatically, or with one click. Quality Score climbs, spend falls.

“We were bleeding budget on job-seekers and freebie hunters. Chaff caught it in an afternoon and cut our wasted spend by a third — without us lifting a finger.”
