Show HN: Structured LLM Output in iOS Shortcuts

1 TweedBeetle 0 5/13/2025, 10:27:25 AM

Hello all,

I recently built an app that allows you to ask Perplexity and OpenAI models for structured data in the form of Booleans, lists and dictionaries in iOS Shortcuts.

This was previously not easy to do despite structured outputs having been around for a while via API.

Here's an example of a shortcut that uses an "Ask GPT for a Dictionary" action to create a calendar event from a screenshot of a conversation discussing the event:

Shortcut: https://www.icloud.com/shortcuts/1e21117f68ba4afebf2d785ae2a...

Some use-cases of app-provided actions include:

* extracting structured output from text to populate calendar events (as shown above)

* smarter filtering in automations triggered by receiving emails or messages

* generating lists for Reminders

* invoking ChatGPT in iOS shortcuts without clogging up your conversation history

Personally, I like having the option of using my own API keys for things and so, the free tier of the app offers unlimited use of OpenAI-text-based actions indefinitely if you bring your own key. Without an API key, daily usage is limited.

The paid tier currently costs $3.99 a month and increases usage limits and unlocks Perplexity-based actions.

All functionality can also be replicated without an extra app by building and parsing requests from scratch. If anyone would like to share such a solution, please feel free.

The app is available on the app store: https://apps.apple.com/app/native-ai-actions/id6447460842

Interested in hearing your thoughts.
