Arc - Radial Menu

Arc - Radial Menu is a macOS menu bar application built by a single developer, Shubham Singh, as part of the OpenAI 2026 hackathon. The app presents a contextual radial menu based on the currently focused application, aiming to improve productivity by reducing the need to memorize keyboard shortcuts.

The description states that Arc supports actions such as opening URLs, launching apps, running shell commands, copying/pasting text, and combining multiple actions into workflows. It includes built-in profiles and allows customization per app context.

Key commercial due-diligence questions include:

• How does Arc determine which app is currently focused?
• What is the actual user base or adoption rate?
• Is there any evidence of monetization or revenue generation?
• How does the AI-generated profile feature work in practice?

The single most important open question is whether Arc has achieved meaningful traction or user engagement beyond its developer's personal use, as no evidence of customers, revenue, or market adoption exists.

The description states that Arc is a macOS menu bar app designed to show contextual radial menus with relevant actions based on the currently focused application. It can be activated via keyboard shortcut and displays actions in the center of the screen.

According to the author:

• Arc stays available alongside standard menu bar controls like Wi-Fi, sound, and battery
• Users activate it using a customizable keyboard shortcut
• The app shows a radial menu centered on screen with actions configured for the current app
• Actions include opening URLs, launching apps, running shell commands, copying/pasting text, and performing multiple actions together
• Built-in profiles and ready-to-use shortcuts are included to reduce setup time
• Each profile can contain up to eight actions and automatically appears based on currently focused app

The product is described as a native macOS menu bar application built using Swift and SwiftUI.

The author states that Arc was inspired by the need to avoid memorizing keyboard shortcuts, with the goal of making productivity tools more discoverable and accessible. The positioning evolved from a simple radial menu for triggering shortcuts into a "context-aware productivity app" capable of running shortcuts, macros, shell commands, launching apps, opening links, copying text, and combining actions.

The author claims that Arc started as a basic radial menu but grew into a system that can adapt to different applications automatically through profiles. The evolution shows an expansion from simple shortcut triggering to workflow automation capabilities.

The description states that the target user is someone who "relies heavily on keyboard shortcuts" and wants to stay productive without constantly switching between keyboard and mouse. It's implied that this includes people who have asked the developer how they remember so many shortcuts, suggesting a user base interested in productivity optimization.

The author notes that Arc aims to be useful even for people who don't know which shortcuts or automations they need, suggesting a broad target audience including both power users and those seeking productivity assistance.

Not evidenced. The description does not contain any information about pricing models, monetization strategies, revenue streams, or business model details beyond the self-reported development process.

The author states that Arc was built using Swift and SwiftUI as a native macOS menu bar app. Key technical capabilities mentioned include:

• Detection of currently focused application
• Global keyboard shortcut listening
• Ability to find installed apps and launch applications
• Running shell commands
• Execution of different types of actions
• Radial menu geometry and positioning
• Handling hover and selection states
• Natural interaction design

The author also mentions using Codex and GPT-5.6 Sol for planning and development, and GPT-5.6 Terra for refining UI/UX details.

Not evidenced. The description contains no information about user adoption, customer base, revenue, usage metrics, or market traction beyond the developer's personal experience and project completion status.

Not evidenced. The description does not mention any existing competitive products, market positioning relative to competitors, or competitive landscape analysis.

• Single-person development team with no evidence of additional contributors
• No revenue, customer base, or traction data provided
• Self-reported only - no independent verification of claims
• Product appears to be a hackathon submission rather than a commercial product
• Unclear how the AI-generated profile feature would work in practice
• No evidence of market validation or user feedback beyond personal experience
