4.7 out of 5
Scored by a Toolio reviewer after real useOur verdict
BrainyAI runs chat, multi-engine search and text explanations from a single sidebar, so selected text can be explained, translated or rephrased with one click. Data collection is opt-in, which is a reasonable privacy stance for a browser extension. Custom prompt management is still listed as an upcoming feature, so anyone wanting that today will have to wait.
