Key features	Access to Claude, ChatGPT, Gemini and Grok from one app A 4.7 out of 5 App Store rating from 1,500-plus ratings Updated as recently as December 2025 Free to download	Unified access to GPT-5, Claude, Gemini, Grok, and Perplexity under one login Library of 50-plus specialized writing tools beyond general chat Image and short-form music generation bundled into the same subscription PDF and document analysis with no separate add-on fee Flashcard and mind-map generation for study and planning use cases
Pros	A single app instead of switching between four provider apps A solid, verifiable App Store rating and review count	Flat $11/month fee undercuts paying for several individual frontier-model subscriptions Access to multiple leading models means switching between them costs no extra Broad tool library covers writing, image, music, and document tasks without extra add-ons
Cons	A third-party wrapper, not an official app from any model provider iPhone only, with no web or Android version The marketing site itself gives almost no detail beyond the App Store listing	No ongoing free tier; the $1 trial still requires a card and converts to a paid plan Monthly word, image, and generation caps mean heavy users can still hit limits Aggregating several models under one product can lag behind each model's own native app in feature rollout speed
Company	Andrew Lee Ventures LLC	NinjaChat AI, founded 2023
