How we score →Not Diamond is an intelligent AI assistant that automatically routes each prompt to the most suitable model from a curated set including GPT-4o, Claude, Gemini, and more. Instead of being locked into one AI, it selects the best model for your task—coding, creative writing, or factual queries—and adapts based on your feedback over time. This means you get higher quality responses without manually switching between chatbots. The system learns your preferences, continuously improving model selection to match your style. For power users and developers, Not Diamond offers an API for custom workflows and team workspaces. It supports multiple models, conversation history, privacy controls, and usage analytics. Currently in invite-only beta, it's designed for those who want a versatile, adaptive assistant that grows with them. The core differentiator is automatic model routing and real-time learning from feedback. Unlike traditional single-model chatbots, Not Diamond leverages the strengths of multiple top-tier models, routing each prompt to the best fit. This ensures more personalized and effective responses. Not Diamond emphasizes privacy and user control. Conversations are stored to improve learning, but users can manage their data. The platform is invite-only, with plans for broader access. It's ideal for early adopters willing to provide feedback in exchange for a cutting-edge experience.
Not Diamond solves a real pain: deciding which AI model to use for each task. Its automatic routing is clever—it picks the best model based on your prompt and learns from your feedback. In practice, this means you get better responses over time without switching tabs. The API is a plus for developers wanting to integrate multi-model intelligence into their apps. When to pick this: If you're a power user who regularly tests different models or a developer building a multi-model workflow, Not Diamond's routing and learning are valuable. Teams needing a shared adaptive assistant will also benefit. When to pass: If you prefer a simple, single-model chatbot like ChatGPT for consistency, the routing adds complexity. Privacy-conscious users may hesitate because data is used for learning (though controls exist). Also, as a beta invite-only product, availability and support are limited. Compared to Chatbot Arena or Poe, which let you manually choose models, Not Diamond automates the choice. It's more personalized but less transparent. We'd reach for this when we want the best response without micromanaging model selection. The main caveat: it's still evolving, and pricing is unclear. For now, it's a promising tool for early adopters.
