In short

WriteMage is a native macOS and iOS overlay that brings ChatGPT to any text field via a Spotlight-style panel. It eliminates copy-pasting by sending context directly to the model.

Best for

Pick WriteMage if you live in macOS apps and want a Spotlight-style ChatGPT panel over every text field without copy-pasting into a browser.

Skip if

Skip it if you're on Windows or Linux, need Claude/Gemini/local model support, or want team-shared prompts and chat history.

WriteMage is a native macOS and iOS utility that bolts ChatGPT onto every text field on your system. Instead of switching to a browser tab, you summon a floating panel (think Apple Spotlight) over whatever app you're in, send the surrounding context to the model, and paste the result back without leaving the document. It keeps per-session context and stores chat history locally with labels for retrieval.

It is aimed at writers, knowledge workers, and Mac power users who already pay for ChatGPT (or hold an OpenAI API key) and resent the constant alt-tab dance. Pricing is unusually founder-friendly: a one-time $58.99 lifetime deal covering both platforms, or subscriptions at $10-$11.87/month. The Personal plan bundles a managed API key, while the Basic plan expects you to bring your own.

This is a thin-but-useful native shell rather than a model lab: you're paying for the OS integration, the prompt editor, and the keyboard-driven workflow, not for a proprietary AI. There is no Windows or Linux version, no team/collab tier, and capability depends entirely on whichever OpenAI model you point it at.

Editor's take

A focused, well-priced native wrapper that does one thing: put ChatGPT exactly where your cursor already is. The lifetime tier is genuinely attractive if you'd otherwise pay a SaaS in perpetuity. Just understand you're buying integration, not intelligence; the model behind it is whatever OpenAI ships next.
