MacGPT — Mac download

The Global feature is a centred text field that appears with a keyboard shortcut, ready for a ChatGPT prompt. It never leaves the app you are working in.

Check the system requirements

The app requires macOS 12 Monterey or newer and runs on Intel and Apple Silicon Macs.

Add your OpenAI credentials

A copywriter's morning, start to finish

A freelance copywriter opens a brief from a client selling outdoor gear. Three product descriptions are due by noon. She keeps Safari, Notes and MacGPT running. The menu bar stays quiet until she highlights a technical term in the brief — "hydrostatic head" — and triggers Inline. The answer appears inside her Notes draft without switching windows. She tweaks the tone, summons Global for a variant headline list, and pastes the best one. By 10:30 the batch is done. No tabs piled up, no login screen, no context lost.

Draft in Bear, Refine with a Keystroke

1. Click the menu bar icon and choose Web Mode to sign in with OpenAI credentials. The ChatGPT interface loads in a compact window.
2. Draft a rough paragraph in Bear, then highlight a sentence that feels flat. Press the assigned keyboard shortcut for Inline and type rewrite for a product page, warmer tone, keep under 40 words.
3. Watch MacGPT replace the original text inside Bear. No copy-paste, no window juggling.
4. Open Global with a second shortcut. A centred overlay appears. Type five SEO-friendly subheadings for a waterproof jacket roundup. Pick two, close the overlay, keep writing.
5. Check the menu bar. A small badge shows the session is still active. Right-click to switch to API mode when you need faster, token-counted replies during a batch task.

Multimodal Prompts Now Feel Snappier

The update added gpt-4o support. In daily use, that means the model picker now includes the newer option alongside earlier GPT-4 variants. Switching models takes two clicks from the menu bar dropdown. Responses feel snappier for image-heavy or multimodal prompts, and the Global overlay handles longer back-and-forth threads without the window stalling — a noticeable difference on an M1 MacBook Air during a research session.

Error messaging also improved. Earlier versions would silently fail when the API key was missing. Now a short, readable alert tells you exactly what to fix. That cuts setup friction when moving between web mode and API mode on a shared machine.

The Inline feature lets you invoke ChatGPT directly inside another app's text box. Select the command and the AI responds in place.
