MacGPT vs WriteMage

MacGPT

The cheapest way to stop alt-tabbing to a browser tab: a hotkey, a menu bar icon, and an inline mode that answers inside the text field you are already in. It costs nothing and you bring your own OpenAI key. It is also a 2023 indie utility that has since been renamed on Gumroad, so treat it as a working tool rather than a supported product.

Pros

• +Menu bar, global hotkey and inline text-field modes
• +Works either through the ChatGPT web session or your own OpenAI API key
• +Listed at zero cost on Gumroad, so no subscription of its own
• +Free iOS companion app, GeePeeTee
• +Named indie developer with a public press kit and privacy policy

Cons

• −Site copyright still reads 2023 and shows no sign of active development
• −The Gumroad product has been renamed MenuGPT, so branding no longer matches the site
• −API mode means you pay OpenAI separately for every token
• −No support commitment of any kind

WriteMage

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.

Pros

• +Overlay works across any macOS app without copy-paste
• +Native iOS keyboard extends the same access to the phone
• +Chat history stored locally, and the developer says the app ships no telemetry
• +A one-time lifetime licence is offered instead of a subscription

Cons

• −Still in beta years after the first build, with no visible release date
• −Most tiers require you to supply and fund your own OpenAI key
• −No company details, terms page or changelog reachable on the site
