PaletteBrain
AI shortcuts for every macOS app, one-time $29 license
PaletteBrain at $29 lifetime is a rare bargain for Mac users who already have an OpenAI API key. You avoid monthly subscriptions but manage your own usage costs. Windows and Linux users need not apply, and those wanting a full chat interface with history should stick with ChatGPT Plus. If you're a macOS power user who lives in multiple apps and wants AI on demand, the one-time cost is a no-brainer. Just be ready to monitor your API usage, as costs can add up with heavy use. Alternatives like Raycast Pro offer a wider feature set but at a recurring price.

Skip PaletteBrain if you're not on macOS, if you don't want to set up your own OpenAI API key and track usage costs, or if you need a full chat interface or non-text AI features.
You pay OpenAI separately for every AI command, so heavy use can rack up API charges far beyond the $29 license.
PaletteBrain's $29 one-time cost fits individual Mac users who already have an OpenAI key and want to avoid monthly subscriptions. Compared to Grammarly Pro ($30+/mo), DeepL ($10+/mo), Raycast Pro ($20+/mo), or ChatGPT Plus ($20/mo), it's dramatically cheaper upfront, but you'll pay your own API usage—so light users save big, heavy users may spend more.
In short
PaletteBrain — AI shortcuts for every macOS app, one-time $29 license. Best for Freelancers and writers who need quick AI editing without leaving their app, Developers needing AI in IDEs and terminals via shortcut, Mac power users replacing multiple AI subscriptions with one tool. Plans from $29.

About PaletteBrain
PaletteBrain is a macOS utility that brings ChatGPT-style AI assistance to every application you use. Instead of juggling windows and copy-pasting text, you select any text—in Slack, Notion, Gmail, Discord, a terminal, or any web app—and invoke a custom AI command with a global shortcut (⌥␣). A menu bar overlay shows pre-built commands like Fix Grammar, Summarize to Bullet Points, Translate to English, and Convert to Blog Post, plus any custom prompts you create. Results paste back with ⌘⇧↵, so you never leave your current app. PaletteBrain is a one-time purchase: $29 lifetime license, after which it's expected to move to $99/year as the roadmap expands. You bring your own OpenAI or Microsoft Azure OpenAI API key and pay usage fees directly to the provider—no hidden middleman. It's built for freelancers, writers, developers, and Mac power users who want AI everywhere without a recurring subscription. PaletteBrain 3, released January 2025, brings performance and stability improvements.
Behind the Verdict
PaletteBrain fills a specific niche: AI assistance that lives in your workflow rather than in a separate chat window. The core value is the global shortcut and menu bar overlay, which let you transform selected text in any app without switching context. For writers, the Fix Grammar and Summarize commands are immediate wins. For developers, being able to select code and run a custom prompt in a terminal or IDE is genuinely useful. The bring-your-own-key model means you pay only for what you use, which can be far cheaper than a $20/month ChatGPT Plus subscription—especially for light users. But that also means you're responsible for tracking API costs, and heavy use can get expensive. The lifetime license is a great deal, but the quoted $99/year future price is a signal that the vendor plans to evolve pricing. The tool is macOS-only, so Windows and Linux users are out. There's no chat history or browsing, so it's not a ChatGPT replacement—it's a complement. If you already rely on ChatGPT, PaletteBrain makes it faster to use; if you don't have an OpenAI key, you'll need to set one up, which is a small hurdle for some. The integrations are thin—really just OpenAI and Azure OpenAI—but that's by design. Overall, for macOS power users who value speed and one-time cost, PaletteBrain is an excellent deal.

Lifetime License
$29 one-time
Ideal for
Individual Mac users who want one-time payment and long-term ownership without recurring fees, especially those who already use or plan to use OpenAI API.
What this tier adds
This is the only tier offered, a one-time $29 payment for lifetime access, including all current features and free updates.
Where the pricing makes sense
The company stage and team size where PaletteBrain's pricing actually pencils out — and where peers do it cheaper.
PaletteBrain's $29 one-time cost fits individual Mac users who already have an OpenAI key and want to avoid monthly subscriptions. Compared to Grammarly Pro ($30+/mo), DeepL ($10+/mo), Raycast Pro ($20+/mo), or ChatGPT Plus ($20/mo), it's dramatically cheaper upfront, but you'll pay your own API usage—so light users save big, heavy users may spend more.
Setup time & first value
How long it actually takes to get something useful out of PaletteBrain — broken out by persona, not the marketing-page minute.
Most users go from download to first command in under 10 minutes: install the app, add your OpenAI API key in settings, and pick a shortcut. Creating custom commands takes a few minutes each—just name it and write a prompt.
Switching to or from PaletteBrain
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Grammarly: You can stop paying $30+/mo and use PaletteBrain's Fix Grammar command, but you'll need an OpenAI key and won't get Grammarly's style suggestions or plagiarism checks.
- →From Raycast Pro: If you primarily used Raycast for AI text actions, PaletteBrain offers a similar shortcut-driven experience without the recurring $20/mo fee, though you lose Raycast's broader launcher features.
- →From ChatGPT Plus: You can keep using ChatGPT via your own API key, and PaletteBrain adds the convenience of invoking it in any app—but you lose the web chat history and browsing.
- ↗To Raycast Pro: If you need a full launcher with built-in AI, Raycast Pro (about $20/mo) offers a wider set of tools, but you'll pay a recurring fee.
- ↗To a browser extension: For AI in web apps only, extensions like Scribe or various ChatGPT assistants might be free, but they don't cover native macOS apps.
