Overview

Ninja AI, built by NinjaTech AI, is a multi-agent AI assistant that routes a user's request to whichever underlying model or specialized agent fits the task best, rather than relying on one general-purpose chatbot. The company was founded in October 2022 by Babak Pahlavan, Sam Naghshineh, and Arash Sadrieh, former Google, Meta, and AWS engineers, and is based in Palo Alto, California.

Behind the single chat interface, Ninja AI dispatches tasks to more than 20 models from providers including OpenAI, Anthropic, Google, Meta, and Amazon, plus the company's own proprietary models, using specialized agents grouped by task complexity: straightforward lookups, multi-step research, and autonomous multi-tool work. A SuperAgent-R reasoning mode and a Deep Research product handle longer investigative tasks without the daily caps common on single-model chat products.

Ninja AI suits individuals and teams who want one subscription covering research, writing, coding, and image or video generation instead of paying for several model subscriptions separately, rather than developers needing direct API access to a specific model. Pricing starts free with six tasks per day, moving to Standard at $5 per month, Ultra at $15 per month, and a Pro tier from $19 per month for expanded model access and higher-quality generation.
