Frequently Asked Questions
How much of an AI tool do users actually use?
Only 3 features on average are used regularly, out of the full feature set (G2). 30% of AI tool features are never used at all (Productiv). Chat/conversation is universal (94% use it). Image generation, code interpreter, and plugins have adoption rates of 19–38% despite being headline features — suggesting discovery, not desire, is the barrier.
How do users discover AI tool features?
Social media is #1 at 41% (Twitter/X, LinkedIn, Reddit). YouTube tutorials are #2 at 28%. In-app onboarding is only #3 at 19% — suggesting most AI product teams are underinvesting in in-product feature education. Official documentation reaches just 12% of users.
What separates power users from casual users feature-wise?
Custom instructions (67% of power users vs. <10% of casual). System prompts, code interpreter, and plugin/GPT use are all power-user behaviors that correlate with significantly higher satisfaction and retention. The implication: helping users activate these features is one of the highest-ROI retention investments an AI company can make.
