OnePrompt is an AI chat enhancement application optimally made for iOS. It significantly improves AI chat interactions by offering an effortless means to switch between chat prompts via the chat screen menu, thereby eliminating manual copying and pasting from a web browser.

The application also supports chat log storage, hence allowing users to save and export chat logs as text to the Files.app. Among its powerful features are plugins that utilize 'function calling,' a feature of the OpenAI API.

This ensures a smooth integration with iOS functions such as Weather, Contacts, and Calendar. In order to further personalize the app according to the user's needs, OnePrompt also provides user-generated custom plugins and default prompts set to initialize when a chat starts.

The application underscores its capabilities not just as a chat interaction tool but also as a strong personal assistant. Safety being a priority, OnePrompt only operates using the user's OpenAI API key and is strictly based on user consent.

It guarantees that the user's information is not employed for machine learning activities or disclosed, emphasizing data protection.
