Harmonic, the AI-driven math startup founded by Robinhood co-founder and CEO Vladimir Tenev, has officially launched its AI chatbot app. The app, available in beta on both iOS and Android, introduces a powerful new tool for users looking to solve complex mathematical problems with ease.
The launch of this AI chatbot app marks a significant step forward in making advanced mathematical reasoning accessible to the masses. Unlike traditional calculators or even more sophisticated software like WolframAlpha, Harmonic’s chatbot, named Aristotle, is designed to understand and solve a wide range of mathematical problems through natural language processing (NLP). This means users can type out their questions in plain English, and Aristotle will provide step-by-step solutions.
For practitioners and students alike, the ability to interact with an AI that can handle complex math problems is a game-changer. Here are some key points:
The architecture behind Aristotle is quite sophisticated:

Initial benchmarks show promising results:
The app’s user interface is designed to be intuitive and user-friendly:
Harmonic is actively working on expanding Aristotle’s capabilities. Upcoming features include:
Harmonic’s AI chatbot app is a significant advancement in making complex mathematical reasoning accessible to everyone. With its powerful NLP capabilities, detailed explanations, and user-friendly interface, it has the potential to transform how we approach math problems. Whether you’re a student, educator, or professional, Aristotle offers a valuable tool for solving and understanding mathematical challenges.

About the author
Kai built ML infrastructure at a Bay Area startup before developing an obsession with transformer architectures and inference optimisation that eventually pulled him out of product work entirely. A stint at a compute research lab sharpened his instinct for what actually matters in a model release versus what is marketing. He writes from the inside — from the perspective of someone who has debugged the systems he is describing at three in the morning. He is allergic to hype and instinctively drawn to the unglamorous plumbing questions that everyone else skips over.
