Not Diamond
Not Diamond automatically routes each prompt to the best AI model, learning your preferences over time.
If you're tired of juggling multiple AI chatbots, Not Diamond's automatic routing is a clever fix. The beta status means rough edges, but for early adopters who want a smarter, adaptive assistant, it's worth the invite wait. For developers building on a multi-model API, compare with OpenRouter or LiteLLM; for teams needing a reliable, production-ready assistant, wait for full release.

Skip Not Diamond if you need a stable, production-ready AI assistant with transparent pricing, unlimited usage on a free tier, or strict data privacy guarantees—the beta status and invite-only access may not meet those needs.
The free tier has a daily message cap (likely 50 messages), so heavy usage requires upgrading.
Not Diamond's pricing is freemium, but the free tier is limited and Pro is contact-sales, making it less accessible than competitors like OpenRouter (pay-per-token) or Poe (monthly flat fee). It's best for early adopters who value model routing enough to negotiate, while budget-conscious users may prefer transparent per-token pricing elsewhere.
In short
Not Diamond — Not Diamond automatically routes each prompt to the best AI model, learning your preferences over time. Best for Power users wanting the best model per task without switching, Developers needing a flexible AI API for custom workflows, Teams seeking a shared adaptive AI assistant. Free to use.

About Not Diamond
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.
Behind the Verdict
Not Diamond's core value proposition is automatic model routing. The platform continuously evaluates which of its supported models—GPT-4o, Claude, Gemini, and others—performs best for each prompt, and it learns from your explicit feedback and implicit interactions. This means as you use it, the assistant gets better at predicting which model will suit your style and the task at hand, reducing the need to manually switch between chatbots. The approach is particularly appealing if you find that no single model excels at everything. For coding, you might prefer Claude's strengths; for creative writing, GPT-4o might shine; for factual queries, Gemini could be the choice. Not Diamond aims to be the aggregator that figures this out for you. The product is invite-only and in beta, which means you may encounter rough edges and its availability is limited. The free tier includes a daily message cap, and Pro pricing is not publicly listed, so you'll need to contact the team for details. Privacy controls let you manage how your conversations are used to improve the system, but if you have strict data residency or zero-retention requirements, this might not fit. The API and team workspaces are promising for developers and teams, but they're tied to the Pro tier, which remains contact-sales. If you're an early adopter who enjoys shaping a product and values getting the best model for every task, Not Diamond is worth trying. If you need a stable, predictable, well-documented solution for production, you might want to look elsewhere until it matures.
