Native AI Chat Desktop App
A paid Mac app that wraps ChatGPT and Claude APIs with power-user features and optional local models.
In plain English
BoltAI is a Mac app for chatting with well-known AI services, with extra controls for people who want more say over the chat, plus an option to run an AI on the Mac itself. Users connect their own AI accounts, and they buy a license they pay for once. The chat is done by those AI services or by the copy running on the Mac, while the app handles licensing and updates with little hand work. The person who builds BoltAI still does a good amount of the work. That work is mainly building the app and marketing it.

Costs

Realistic income
Needs real Mac/Swift skill. The market has been crowded since official ChatGPT and Claude desktop apps launched.
Risks

- Platform competition from the model vendors themselves.
