ChatGPT + Chapeta's 9 Tools
Most AI apps let you chat. Chapeta lets ChatGPT actually do things on your Mac - run terminal commands, search the web, read and edit files, capture screenshots, and more.
What ChatGPT's Official App Can't Do
ChatGPT Plus costs $20/month for GPT access, even if you only use it a few times a week.
Locked to OpenAI models only - can't use Claude for analysis, Gemini for speed, or DeepSeek for cost savings.
Limited tool execution - ChatGPT can generate code but can't run it on your Mac, edit local files, or control applications.
No BYOK option - you must pay the subscription even if you'd prefer to use your own API key at per-token rates.
Cloud-only conversations - all history stored on OpenAI's servers with no local-only option.
Chapeta removes these limitations by giving you ChatGPT alongside the best models from every major provider and 9 executable tools in a single native Mac app.
