what is cue fr?

cue is a free, open-source app for Mac computers that acts like a personal AI assistant floating on top of your screen. It watches your screen, listens to your microphone, and listens to the audio from meetings, then uses an AI model you choose to help you in real time. It is built as an alternative to a paid product called Cluely, and instead of charging a subscription, it asks you to bring your own API key from a provider like OpenAI, Anthropic, or Google Gemini, so you only pay that provider for what you actually use. The app offers several features you trigger with keyboard shortcuts or buttons. One helps during live conversations by suggesting what to say next, using both what you hear and what the other person says. Another looks at your screen to solve a coding problem and gives you the code along with an explanation of its efficiency. There is also a recap feature that summarizes the whole conversation, and a follow up question generator. A toggle lets you switch between a faster, cheaper AI model and a smarter but slower one. A central design goal is staying hidden during screen shares, so the panel does not appear when you share your screen in tools like Zoom, Google Meet, or Microsoft Teams, though the README is upfront that this protection is best effort rather than guaranteed and depends on settings within each app. It notes that using a hidden assistant during things like exams or interviews may violate rules or laws, and puts responsibility on the user. Most people are expected to install cue by downloading a ready-made Mac app from the releases page, though developers can also run it from source code using Node.js. Under the hood it is built with Electron, and everything happens on your own computer except the actual calls made to your chosen AI provider. Your API key is stored only locally and is never sent anywhere except that provider.
