Howler Mac app offers AI chats that disappear when closed
Howler is an open-source app for Mac computers that lets users ask questions of supported AI models in a pop-up chat.
Chinese developer Aries Zhou made it for quick questions that do not require opening a browser or a separate chat session.
Users open the parchment-style window with a keyboard shortcut and press Escape to dismiss it, making the conversation disappear from the app.
Howler says it keeps messages in memory and stores no chat history or logs on the Mac.
It can connect to online AI services using an API key or to compatible models running locally, but the AI provider may still keep a record of an online exchange.
Setting up the app requires an AI coding agent or running configuration commands manually.
Users can find Howler on GitHub or its website; the app also offers an option to disable its update checks.
