Frequently Asked Questions
Brain or chip icon for an AI feature?
A circuit-brain hybrid signals AI most clearly. A plain anatomical brain leans medical, and a bare chip leans hardware. If your product is a general AI assistant, the sparkle icon has also become a common convention.
Are these appropriate for mental health apps?
Yes, but soft rounded outline styles test better in wellness contexts than clinical anatomical drawings. Pair them with calm colors and avoid red, which reads as an emergency indicator.
