MacGPT vs PaletteBrain

MacGPT

The cheapest way to stop alt-tabbing to a browser tab: a hotkey, a menu bar icon, and an inline mode that answers inside the text field you are already in. It costs nothing and you bring your own OpenAI key. It is also a 2023 indie utility that has since been renamed on Gumroad, so treat it as a working tool rather than a supported product.

Pros

• +Menu bar, global hotkey and inline text-field modes
• +Works either through the ChatGPT web session or your own OpenAI API key
• +Listed at zero cost on Gumroad, so no subscription of its own
• +Free iOS companion app, GeePeeTee
• +Named indie developer with a public press kit and privacy policy

Cons

• −Site copyright still reads 2023 and shows no sign of active development
• −The Gumroad product has been renamed MenuGPT, so branding no longer matches the site
• −API mode means you pay OpenAI separately for every token
• −No support commitment of any kind

PaletteBrain

A cheap, honest deal: one payment puts GPT into every Mac text field, and because you bring your own key there is no markup on model usage. The catch is scope — it is a thin OpenAI/Azure wrapper from a small indie vendor, with no Windows version and no support for Anthropic, Google or local models mentioned.

Pros

• +One-time $29 license instead of a recurring fee
• +Works on selected text in any macOS app or website
• +Custom command library with per-command shortcuts
• +Text goes only to OpenAI/Azure — no middleman server

Cons

• −Useless without a separately billed OpenAI or Azure key
• −Locked to OpenAI-family models; no Claude, Gemini or local options stated
• −Single-developer product, so long-term maintenance is a bet
