Developer builds menu bar AI with note-taking, trading, and task automation

A developer posting on Hacker News describes an AI tool they have built that operates from the menu bar—the system toolbar area at the top of a computer screen—rather than as a traditional chat box application. The tool is designed to stay accessible and out of the way while offering multiple distinct modes of operation.

The note-taking capability supports up to three hours of recording, likely allowing extended audio or text capture. A stock trading mode incorporates 16 indicators, enabling the tool to assist with financial analysis and trading decisions. A stealth mode is included specifically for use during tests or by college students, implying the tool can operate quietly without drawing attention. An observing agent explains content that appears on the user's screen, functioning as a real-time information assistant. A separate red agent performs actions in the background—specifically mentioned are sending emails and completing homework—without requiring the user to interact with a chat interface each time.

The developer is explicitly uncertain whether this design and feature combination represents a sound product direction. They posted to solicit community feedback on the core viability of the menu bar approach and the assembled feature set. The post has received minimal engagement (1 point and 1 comment) as of the posting date, indicating it is in an early-stage testing phase within the developer community.

The developer's approach reflects a shift in how AI interfaces might integrate into daily workflows. Rather than requiring users to open a dedicated application or chat window, menu bar placement makes the tool persistently available yet out of the way—a design pattern common in system utilities, weather apps, and notification managers. The feature set spans productivity (note-taking, observing/explaining), finance (stock trading), and academic/professional assistance, suggesting an attempt to serve multiple use cases from one tool.

The mention of stealth and background execution modes indicates the developer is thinking about contexts where discrete AI operation matters—exams, for instance. However, these same capabilities (background email sending, homework completion without user interaction) introduce questions about transparency and intended use that the developer may need to address as the tool matures. At present, with 1 point and 1 comment on the developer community forum where it was posted, the tool is in very early stages of public exposure and feedback collection.
