NppOpenAI — OpenAI (aka. ChatGPT) plugin for Notepad++

A simple Notepad++ plugin to communicate with OpenAI directly from your favorite code editor.

How it works?

Simply select your text in Notepad++, press Ctrl + Shift + O, and you'll see the AI generated response in seconds. (Additional settings required.) Two examples: "Please create a Fibonacci function in PHP"; "Mi az árvíztűrő tükörfúrógép?" (Hungarian Unicode test). This plugin requires an active internet connection and an OpenAI registration / API key (handles it confidentially).

How to configure?

To remove your original question/request, please uncheck Plugins » NppOpenAI » Keep my question option.

For additional settings, please open the configuration file (NppOpenAI.ini) from Plugins » NppOpenAI » Edit Config, and edit the [API] section. For available plugin settings, see OpenAI API Reference. You can track your token usage via the total_tokens_used setting in [PLUGIN] section.

To send a system message (I call this “instructions”) along with your question, please open the instructions file (NppOpenAI_instructions) from Plugins » NppOpenAI » Edit Instructions. How to use? For example:

• Click Plugins » NppOpenAI » Edit Instructions
• Enter any instruction, like: Please translate the received text into English.
• Save the file
• Click Plugins » NppOpenAI » Load Config
• Open an empty file and enter e.g. Kérlek, mondd, hogy ez egy teszt
• Select the text and press Ctrl + Shift + O
• You should get the following result: “Please, say that this is a test”, instead of “Ez egy teszt” (“This is a test”).

If you don't want to use “instructions”, please leave the NppOpenAI_instructions file empty.

After editing and saving NppOpenAI.ini and/or NppOpenAI_instructions, please always load your settings: Plugins menu » NppOpenAI » Load Config.

To enable chat, please click Plugins » NppOpenAI » Chat: off menu item, and check in the Use chat. You may also increase/decrease chat limit for optimal token usage. To turn off chat, please click Plugins » NppOpenAI » Chat limit: [numeric limit] and turn off Use chat.

The chat can even be used in conjunction with the “instructions”. However, the chat history to be displayed is not (yet) available.
