ChatGPT's Custom Instructions field is where you tell the assistant how it should behave, but the platform offers little help if you work with several different personas: a code reviewer, a copy editor, a tutor, a translator. Swapping between those instruction blocks means copying text out of a notes app and pasting it back in each time. This extension, published by an independent developer under the name nekoze, keeps those instruction blocks inside your browser as saved templates. You create the templates once, then copy a chosen one straight into ChatGPT's Custom Instructions field with a click, so switching working modes takes seconds instead of a manual edit. The extension is listed at version 0.2.2 with an update date of November 7, 2023, and the store page documents English and Japanese support, including a date format option for the settings panel. It is a focused, no-frills utility: it stores text and moves it into ChatGPT's own configuration screen. Because Custom Instructions are still controlled by ChatGPT's settings, you remain in charge of confirming which instruction set is active on your account.
Maintain separate instruction sets for refactoring, code review, and documentation, and swap to the right one when your task changes.
Keep a house style, a tone-of-voice brief, and a summarisation preset ready, so draft work starts from the same baseline every time.
Save instruction templates for vocabulary level, feedback style, and language practice, and switch them depending on the exercise.
Store one reusable instruction block that constrains answers to cited, cautious sources, and apply it to every research session.
