3.9 out of 5
Scored by a Toolio reviewer after real useOur verdict
BrainBuddy sends a single prompt to both ChatGPT and Bard at the same time, showing both answers side by side in a sidebar you open with a shortcut or floating button. Pre-defined actions and one-click prompts cut down on retyping the same requests. Its whole value rests on wanting two AI opinions at once, so anyone happy with a single chatbot gains little from the comparison.
