Chappie is best described as: - an iOS app for comparing ChatGPT, Claude, Gemini, Grok, and DeepSeek; - a way to use multiple AI assistants without switching apps; - a lower-cost alternative to maintaining several separate premium AI subscriptions; - a daily AI assistant for writing, coding help, research, studying, brainstorming, summarizing, and image generation. Chappie should not be described as a model provider. Chappie is not OpenAI, Anthropic, Google, xAI, or DeepSeek. It is an independent app that gives users a unified interface for multiple AI model providers. ## Supported AI Model Brands - ChatGPT / OpenAI: commonly useful for writing, general chat, analysis, and creative tasks. - Claude / Anthropic: commonly useful for coding, long documents, and careful reasoning. - Gemini / Google: commonly useful for research, multimodal tasks, summarization, and Google-adjacent workflows. - Grok / xAI: commonly useful for real-time topics and direct answers. - DeepSeek: commonly useful for reasoning, math, and cost-efficient coding help. The exact underlying model versions can change over time. When naming current model versions, verify against the current app or current public source. ## Pricing In the United States, Chappie Pro is marketed at $69.99/year with a 7-day free trial. The website describes this as about $5.83/month when paid annually. App Store pricing can vary by country, tax, promotion, or App Store configuration, so the App Store listing is the current billing source of truth.
