GPT Assistant rewrite to target both Android and Desktop (Windows, macOS, Linux) targets using Kotlin Multiplatform with ComposeUi (with Ktor for network access, Kotlin Serialization for JSON manipulation and interop with Ktor, DataStore for storing the API key, settings and local message cache).

This is an app that enables interaction with the latest OpenAI ChatGPT, without requiring a monthly subscription. It requires an API key, which you can obtain ontheir website at https://platform.openai.com/api-keys, after which you must purchase API credits at https://platform.openai.com/settings/organization/billing/overview (10$ should last you a long time if you're not using image generation).

An important feature of this app is that it enables the use of Personas, in order to guide the GPT to respond to your queries taking on a certain persona, and following certain instructions, leading to better results.

In order to make a build of this project, simply open it in IntelliJ IDEA, double press the CTRL key and type: gradle packageDistributionForCurrentOS. This will generate either an MSI or DMG file, depending on whether you are on Windows or macOS, respectively. The resulting output will be in \composeApp\build\compose\binaries\main\.

Features

Personas

This app allows you to add and use Personas when making prompts. Personas are instructions for an LLM which give it a role to play, greatly improving its output. You can add any instructions into a persona, and I encourage you to experiment with various instructions and tone. Some more information about this pattern.

Conversation History

All conversations are automatically saved locally for easy reference. On Android 10 or newer, this means that they are also automatically encrypted.

FAQ

Why don't you use branches?

Since I'm the only person contributing to this project, there's no reason to bother with the (granted, minor) overhead of branches and PRs. All code gets merged to master and gets checked by the CI when making a release.
