About

Quantu

Read full description

Quantu lets you create your own on chain AI agent simply by speaking. You describe what you want out loud, and the app instantly turns your words into a fully functional agent with its own identity, logic and presence on chain. This is creation in its most natural form. No typing, no building, no configuration. You speak, and your agent exists. Quantu is designed for crypto users who want real ownership and complete creative freedom. From the moment your agent is created, it belongs to you. It carries its own on chain identity, a reputation that grows through usage and a decentralized memory that your community can expand as they interact with it. Nothing is locked inside a platform. Everything the agent becomes stays in your hands. Sharing your agent is just as flexible. You can make it public, keep it for your holders, restrict it to your social circle or turn it into an exclusive experience within your ecosystem. Your agent becomes a living extension of your digital identity and an asset that can travel across environments as easily as any token or collectible. The decentralized memory system gives your agent long term continuity and makes every interaction meaningful. What your agent learns, remembers and builds over time belongs to you and to your community. Knowledge becomes a shared asset rather than a platform-owned resource. With Quantu, an agent can also become a micro-economy. You can enable token-gated access, unlock features through staking, monetize interactions through x402 services or distribute the agent as a resource to your audience. You can even choose to sell the agent later as a complete on chain asset with identity, memory and reputation already established. What begins as a spoken instruction can evolve into a valuable element of your ecosystem. Quantu is built for people who want to create freely, own what they build and bring their community into the experience. It is not another chatbot. It is your on chain agent, created with your voice, shaped by your vision, strengthened by your community and fully owned by you

Then ask PhiNote anything about them: "What did I write about SN2 reactions?" or "Summarize chapter 4."

Get scored, see exactly which questions you missed, and review before your next session. Why on-device matters: โ€ข Your notes and questions never touch a server โ€ข Works with zero internet connection โ€ข No accounts required to use the AI โ€ข Nothing to leak, nothing to subscribe to just to feel safe Built for iPhone and iPad, with a proper split-view layout on iPad so your notes and chat sit side by side. Free to write, organize, and read your notes. Unlock on-device AI โ€” chat and Quiz Me โ€” with a one-time purchase. Private by design. Smart by default.
