Mine what people actually search
Keyword Tool uses Google Autocomplete to generate hundreds of long-tail keyword suggestions for any term, pulling from the real queries people type into search.

Reliable by design
The '99.99% of the time' framing reflects a focus on dependability — it consistently returns useful suggestions, which matters when keyword research is a routine part of your workflow.
