## Overview

PaletteBrain solves a very specific everyday friction: you constantly switch windows and copy-paste text back and forth just to use AI. PaletteBrain instead lives in the menu bar and responds to a keyboard shortcut, so you can highlight text in any Mac app and run an AI command on it in place.

Under the hood it connects to the OpenAI API (and can use Microsoft Azure OpenAI), so you get the latest models with pay-as-you-go pricing billed directly by OpenAI. You can define your own commands for the tasks you repeat — correcting grammar, translating, summarizing, refactoring code — and trigger them from anywhere.

The business model is a one-time purchase rather than a subscription, marketed as a cheaper alternative to stacking monthly tools like grammar checkers, translators, and AI writing assistants.

## Pricing & Plans

Paid, one-time purchase. PaletteBrain sells a lifetime license (promotional price around $29 at the time of writing) with no recurring subscription; you supply your own OpenAI API key and pay OpenAI directly for usage.

## Key Features & Capabilities

- **AI anywhere with a shortcut:** Select text in any macOS app or website, press a shortcut, and run an AI command without leaving the window you are working in.
- **Custom AI commands:** Create your own prompts and commands for the tasks you repeat most, from rewriting to refactoring code.
- **Bring your own OpenAI or Azure key:** Connect your own OpenAI key, or run Microsoft Azure OpenAI for faster, dedicated infrastructure and experimental models.
- **One-time purchase, no subscription:** One low one-time price instead of stacking subscriptions for grammar, translation, summarization, and AI writing tools.
- **Latest models, pay as you go:** Access the latest OpenAI models directly without needing a ChatGPT Plus subscription.

## Primary Use Cases

- **Polish text anywhere on your Mac (Writer / knowledge worker):** Fix grammar, rewrite, and translate text in place inside emails, docs, and chat without copy-pasting.
