Show HN: Howler, a macOS menu bar AI that burns the chat after reading (github.com)

Howler, a newly launched macOS menu bar application, allows users to ask questions in a unique format reminiscent of a sealed letter, with answers generated by AI and displayed in an engaging, animated manner. Users can initiate the experience by pressing ⌥H, which opens a virtual parchment where their questions are written and answered by a quill that mimics handwriting. Crucially, once users finish reading or dismiss the letter, it "burns," meaning the conversation is not saved, enhancing privacy and ensuring no chat history exists. This application is significant for the AI/ML community as it emphasizes user privacy and simplicity while leveraging AI's capabilities for natural language processing. Howler supports multiple model services and simplifies configuration, requiring no API key input during chats, as the key is securely stored in the Keychain. With its focus on ephemeral interactions and elegant design—powered by Swift and Xcode—Howler sets a precedent for future applications to prioritize user experience and data security, while promoting a blend of functionality and aesthetics in the realm of conversational AI tools.
