PaletteBrain
A macOS menu-bar app that runs your own OpenAI or Azure OpenAI prompts on selected text in any app with ⌥␣
At $29 for a one-time macOS license, PaletteBrain is an easy call if you already pay OpenAI for API usage and want prompt access inside the apps you actually type in. The ⌥␣ overlay plus paste-back is the whole product, and for grammar fixes, translations, bullet summaries, and custom rewrites that is enough. Two caveats. First, the vendor's own homepage says the lifetime license moves to $99/yr as later roadmap phases land, so treat $29 as the current entry price, not a forever price. Second, you carry your own OpenAI or Azure OpenAI key and pay usage directly — cheap for light use, unbounded for heavy use. If you want a broader Mac command bar with extensions, look at Raycast Pro, which

Skip PaletteBrain if you work primarily outside macOS, want a chat interface with saved conversation history, or need your team to share one API key and one bill rather than every person bringing their own OpenAI account.
Your OpenAI or Azure OpenAI usage is billed by the provider on top of the $29 license — the vendor's own comparison assumes under $2/mo of base usage, and heavy document work will run past that
A $29 one-time license plus pay-as-you-go OpenAI usage fits solo Mac users and freelancers who already hold an API key. Stacked against the subscriptions the vendor itself names — Grammarly Pro at $30+/mo, Jasper AI at $39+/mo, ChatGPT Plus at $20/mo, Notion AI at $10+/mo, Raycast Pro at $20+/mo — it is the cheapest entry point if your usage is moderate, and the most expensive if you push large documents through it constantly.
In short
PaletteBrain — A macOS menu-bar app that runs your own OpenAI or Azure OpenAI prompts on selected text in any app with ⌥␣. Best for Freelancers and writers who edit text inside many different apps, Developers who want prompt access in an IDE or terminal without leaving it, Mac power users consolidating Grammarly, DeepL and similar subscriptions.

What is PaletteBrain?
PaletteBrain — A macOS menu-bar app that runs your own OpenAI or Azure OpenAI prompts on selected text in any app with ⌥␣. Best for Freelancers and writers who edit text inside many different apps, Developers who want prompt access in an IDE or terminal without leaving it, Mac power users consolidating Grammarly, DeepL and similar subscriptions. Plans from $29 one-time.
PaletteBrain is a macOS app that puts AI commands one keystroke away inside the programs you already use. You select text — in Notion, Google Docs, Slack, Discord, Gmail, or a terminal — press ⌥␣, and a menu-bar overlay offers pre-built commands such as Fix Grammar & Spelling, Translate to English, Summarize to Bullet Points, and Convert to Blog Post, plus any custom commands you write yourself. Results paste back into the same app, so you never leave the window you were working in. You supply your own OpenAI API key, or swap in a Microsoft Azure OpenAI key to run models on Azure infrastructure, and you pay the provider directly on a pay-as-you-go basis with no middleman markup. The vendor sells a one-time lifetime license at $29 throughout its homepage, and states plainly on that page that the price will move to $99/yr as later roadmap phases arrive — so treat the $29 figure as the current entry price, not a permanent model. It is aimed at freelancers, writers, developers, and Mac power users who want prompt access everywhere without stacking yearly subscriptions to Grammarly, DeepL, Jasper, or ChatGPT Plus. It is not a chat client: there is no conversation history surface, and no Windows or Linux build.

Models under the hood
as of 2026-11-03
Limitations
- PaletteBrain is macOS-only and needs your own OpenAI or Microsoft Azure OpenAI API key, so your real cost is the license plus whatever the provider bills you — light editing stays cheap, heavy document processing does not.
- It has no chat window with browsable history and no image, voice, or audio features; output is text transformed in place.
- The vendor states on its own homepage that the $29 one-time lifetime license will move to $99/yr as later roadmap phases arrive, so treat the current price as a time-limited entry point rather than a permanent model.
- The homepage describes model access generically ('the latest models from OpenAI') without naming versions, so the exact model you get depends on what your own API key is entitled to.

GeneratedReal-world workflow fit
Concrete scenarios for the personas PaletteBrain actually fits — and what changes day-one when you adopt it.
You are drafting in Google Docs, select a clumsy paragraph, hit ⌥␣ and run Fix Grammar & Spelling, then paste the cleaned version back into the doc without leaving the tab.
Outcome: Editing stays inside the document you are already in, and you pay OpenAI for the tokens rather than a monthly grammar subscription.
You select an error message in a terminal or an IDE, press ⌥␣, and run a custom command that asks the model to explain the failure and suggest a fix.
Outcome: You get the explanation next to the code you are debugging instead of switching to a browser chat window and re-pasting the error.
You select a message before sending it, run Translate to English or Fix Grammar & Spelling from the menu-bar overlay, and send the corrected version.
Outcome: Messages go out clean in a second language without a separate translation app or a browser tab.
Use cases
- Fix grammar and spelling in any Mac text field without switching apps
- Translate selected text to English with one shortcut
- Summarize a long paragraph or article into bullet points in place
- Turn a short note into a full blog post using a custom command
- Rewrite selected text for tone, style, or clarity with a custom prompt
- Define a selected word or phrase using your own model key
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.
Roughly 10-15 minutes for a solo Mac user: download the app, paste in your OpenAI (or Azure OpenAI) API key, and try the ⌥␣ overlay once. Writing your first custom command adds a few more minutes. Teams have no shared setup path — each person configures their own key.
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: keep your existing drafts, install PaletteBrain, and rebind the grammar fix to a custom command so the ⌥␣ habit replaces the Grammarly popup
- →From DeepL: recreate your translation presets as custom commands and select text then press ⌥␣ instead of copying into the DeepL window
- →From ChatGPT Plus: cancel the subscription, paste your OpenAI API key into PaletteBrain, and pay per token instead of the flat monthly fee
- ↗To Raycast Pro: Raycast's AI commands plus extensions cover a broader Mac command-bar surface if you want more than text transformation
- ↗To ChatGPT Plus: if you mainly want a chat interface with saved history, the subscription is the more direct fit than a selection-based overlay
