Most chat-AI shortcuts make you paste in an API key, sign up for something, or watch them break the moment a backend disappears. Pro AI used to have that problem too. After almost a year of being broken it got a full rewrite, and the version you install now talks to a hosted API that the developer pays for, so you just run it and start typing.
What it does
Pro AI is a conversational assistant you run straight from the Shortcuts app. Ask it a question, get an answer, keep the thread going. The current build runs on a GPT-5.4-Nano model behind a custom API, and the chat keeps context across turns until you clear it. It’s deliberately lighter than the old version: the menu, vCards, and a few other extras were cut so the shortcut builds faster and lags less while running.
What you need
- Shortcuts app — the only requirement. There’s no second app to install and no key to generate; the developer covers the API cost.
How to install
- Tap Add Shortcut on this page to open Pro AI in the Shortcuts app.
- Review the actions if you like, then scroll the preview to the bottom and tap Add Shortcut again.
- Run it from your shortcut list, a Home Screen icon, or by asking Siri.
First run
There’s nothing to configure before your first chat. Open the shortcut and type a message. One thing to keep in mind from the start: each request caps at 1,000 characters, so break a long prompt into a couple of messages rather than pasting an essay. The rate limits are light too, 10 requests a minute and 1,000 an hour, which you’d only hit by hammering it.
How to use it
Day to day you just type and read replies. A few text commands change what happens:
- Type
voice(exactly that, nothing else) to switch into voice chat. - Type
/resetto wipe the conversation history and start clean. - Type
/doneto exit the shortcut.
There’s also a built-in weather lookup, so a quick question about the forecast gets answered inline without leaving the chat. When a reply starts drifting off an earlier tangent, /reset is the fastest way to give it a blank slate.
Tips
The character cap is the thing people bump into first, so it helps to ask one focused question at a time instead of stacking three into one message. If you want Pro AI reachable in a hurry, drop it on the Home Screen or wire it to a Back Tap, and voice mode covers the moments your hands are busy. Because the whole thing leans on a hosted API, it needs an internet connection to answer anything.
FAQ
Wait, do I actually need to pay or add a key?
No card, no key. The developer hosts the API and pays for it, which is why there are rate limits in place to stop spam from burning through credits.
Why does it tell me my message is too long?
Single requests are capped at 1,000 characters. Trim the prompt or split it across two messages and it’ll go through.
How do I get out of voice chat or end the session?
Typing /done exits the shortcut. To keep chatting but clear what it remembers, use /reset instead.
