PaletteBrain

Select text in any Mac app, press a shortcut, and PaletteBrain sends it to ChatGPT and returns the result where you are working.

PaletteBrain is a macOS app that connects ChatGPT to other applications through keyboard shortcuts, so you do not need to copy text into a separate chat window.

Its palette commands cover the usual assistant jobs: rewriting and grammar fixes, summaries, translation, code help and prompt writing.

Conversations and messages are unlimited on every license.

Pricing is a one-time payment rather than a subscription.

The Personal License costs $29 for one computer.

The Family License costs $99 and covers five macOS devices, which suits a household or a small group sharing a purchase.

Both include lifetime auto-updates.

Teams, startups and larger companies can get a Team License with as many devices as they need, priced by contacting the seller.

Because it is macOS only, PaletteBrain is no use if you work on Windows or Linux.
