About Chappie
One place for the AI models you already use.
Chappie is an iPhone AI chat app that brings ChatGPT, Claude, Gemini, Grok, and DeepSeek into one conversation experience. It is built for people who want to choose the right model for each question without scattering their work across separate apps and histories.
What Chappie is
Different AI models are useful for different kinds of work. Chappie puts several leading models in one native iOS app so people can use them for writing, coding help, research, studying, brainstorming, summarizing, and image generation without rebuilding context every time they switch tools.
You can compare answers to the same prompt side by side, change models during a conversation, and keep a unified chat history. The goal is straightforward: spend less time managing AI products and more time using the answer that best fits the task in front of you.
How we approach the product
Choice over lock-in
No single model is best at everything. Chappie keeps model choice visible so you can match the tool to the job.
Continuity over switching
Conversations and context should remain useful when you change models, rather than being trapped in separate app histories.
Clear boundaries
Chappie is independent. It is not owned by, endorsed by, or affiliated with OpenAI, Anthropic, Google, xAI, or DeepSeek.
Company and people
Chappie is developed and operated by Mitissa, LLC, an independent software company. Jason Safaiyeh is the developer identified on the App Store and the editor behind Chappie’s public comparison guides.
