Adds six columns to every row: intent (informational / commercial / transactional / navigational / unclear), intent_confidence (0-1), intent_runner_up and intent_runner_up_probability (the strongest other class — so an "unclear" at 0.63 also tells you what it leaned toward), intent_note and intent_rubric_version. Free — this option adds no charge and no billing event; a run costs exactly the same with it on or off. EXPERIMENTAL, accuracy not yet published: a keyword the classifier is not confident about comes back as "unclear" rather than as a guess, and if classification is unavailable the row carries intent null with a machine-readable reason in intent_note. Your search volume, CPC, competition and trend data are never affected by this option and the run never fails because of it. Default false — with it off, rows carry exactly the columns they always had. With this option on, each keyword text plus the country and language you selected is sent to an external classification service to determine intent; no volume, CPC, competition or account data leaves this run for that purpose. With it off, nothing is sent.
