OppenheimerGPT: two AI brains, one app!
OppenheimerGPT: Compare ChatGPT & Bard Side-by-Side on Mac
A handy macOS menubar app that lets you fire one prompt into both ChatGPT and Google Bard simultaneously, so you can compare answers instantly without juggling browser tabs.
Overview
OppenheimerGPT is a lightweight macOS utility built for anyone who wants the best of both AI worlds without the hassle of switching tabs. Living quietly in your menubar, it mirrors every prompt you type into both ChatGPT and Google Bard (Gemini) at once, displaying their responses side-by-side so you can instantly compare tone, accuracy, and creativity between the two leading chatbots. It even extends the same side-by-side philosophy to search, letting you run Bing and Google queries in parallel.
Beyond quick menubar access, the app supports standalone windows, making it easy to research multiple topics at the same time without losing your place. Since it essentially mirrors browser-based sessions, there's no backend server storing your logins or prompts—everything happens locally on your machine, which is a reassuring touch for privacy-conscious users. With a free Basic tier and an affordable one-time Pro upgrade, OppenheimerGPT positions itself as a scrappy, indie-built productivity tool for the age of multi-model AI.
Whether you're a developer sanity-checking code suggestions, a student comparing explanations, or a content creator hunting for the punchier draft, OppenheimerGPT removes the friction of flipping between tabs and turns AI comparison into a single, streamlined workflow.
