Floating ChatGPT window and iOS keyboard that works inside any Mac or iPhone app
WriteMage puts a ChatGPT prompt box on top of whatever Mac app you are in, Spotlight-style, so you can draft or rewrite text without switching windows or pasting between apps. It keeps session memory, stores chat history locally with labels, and ships a GUI prompt editor for customising the instructions it sends. On iOS the same thing arrives as a system keyboard usable in any app from the store. It is an indie product from a single developer, still labelled beta on the site, and most tiers expect you to supply your own OpenAI API key.
Free to use while the app remains in beta. After release the site lists a lifetime licence discounted to $58.99 from $119.99, Basic at $10/month or $119.99/year (list $159.99), and Personal at $11.87/month or $142.49/year — the only tier where the vendor covers API usage, at 750,000 words a month. Other tiers require your own OpenAI API key, and unlocking bring-your-own-key on iOS is a separate $25 in-app purchase.
Use tool ↗The idea is right — an AI prompt floating over any app beats copying text into a browser tab — and the bring-your-own-key model makes it far cheaper than subscription assistants. The catch is maturity: the app has been in beta since its first build in late 2022, the site still advertises a launch sale for a final version that has not shipped, and there is no company behind it.
Watch out: The site's urgency copy — a launch sale 'available until the final version is released', which 'should be released this month' — has evidently been up for a long time. Treat the roadmap as stalled and buy the lifetime deal only if the current beta already does what you need.
