A Voice AI Tutor Without Swift or Kotlin

William Imoh, founder of Hackmamba, describes the creation of Mural, a voice-driven language tutor powered by agents. He claims to have developed an iOS and Android app using Codex and GPT-Live-1, without writing in Swift or Kotlin, and has established a well-equipped organization where designated agents manage the daily operations of a 25-person team.

Real-time voice supports Mural but costs $3 to $5 per half-hour

William Imoh believes that real-time voice technology is now reliable enough to build a service around, although it remains costly. He asserts that Mural would not have come to fruition without GPT-Live-1. According to him, a 30-minute session costs about $3 to $5, a price he considers high for software but lower than that of an on-demand human tutor.

Designated agent roles drive a 25-person company

The leader describes a team of Grok Bots agents inspired by The Lord of the Rings that contributes to managing a company of 25 people. Gandalf serves as the chief of staff, Legolas handles marketing, and Aragorn oversees sales, while Elrond is positioned in engineering. He believes that giving these agents distinct identities and specific missions facilitates their understanding and task delegation. These agents have been connected by him to Google Workspace, Linear, Notion, Pipedrive, QuickBooks, his calendar, and various navigation tools, benefiting from extensive access while ensuring the protection of banking information and customer data. He also mentions using Grok Bot to analyze the results produced by Cursor.

Coding without Swift or Kotlin: Codex structures the native app and design

William Imoh argues that when agents write the code, prior mastery of programming languages matters less. He explains that he used Codex and GPT-Live to create the iOS and Android versions, despite having no experience in Swift or Kotlin, and claims that the tech stack followed the product vision. He requested a minimalist app of Apple quality reminiscent of autumn; the first version in dark mode was reoriented towards warm colors, gradients, and a lighter style. He attributes the quality of the results to structured queries like epics and user stories tied to specific problems. Mural, he assures, teaches through total immersion. In case an agent gets stuck, he recommends restarting a session, breaking down the task, adding a reviewer, and requesting a self-inspection.

From the Norwegian breakthrough to in-house tools and a vision of skills

As the founder of Hackmamba and creator of Mural, William Imoh links his project to a personal experience: a 1,000-day streak on Duolingo without being able to hold a conversation in Norwegian. He believes that the future of organizations relies on custom-designed management solutions enhanced by AI. He explains that he developed Three Pipes, an internal HR tool that aggregates emails, calendars, and meeting notes to ensure tracking and sorting of candidates, choosing to build the necessary database for his company rather than adopting standard software. He also states that advancements in models make the creation of sophisticated skills libraries less essential, as most of his own expertise has proven unnecessary in his view, except for what he considers enduring: growth strategy, content strategy, and eliminating AI-style writing.
