Chrome addon to lookup selected text via ChatGPT using custom prompts
Made this (GPT-4 made this actually) for myself mainly to do quick lookups on selected text. Add your api key and then your own system prompts in options. Then from context menu send selected text to ChatGPT with one of your prompts. Result should appear on top of page. I haven't looked much into publishing this on store yet, might do that later. At the moment, you have to load this in Developer mode via Load Unpacked button on extensions page in chrome. Tip: if you have only one prompt enabled, context menu will not be nested.

In plain words
This Chrome extension allows users to quickly look up selected text by sending it to ChatGPT with custom prompts. After adding an API key and configuring system prompts in the options menu, users can right-click any selected text to query ChatGPT via the context menu, with results displayed at the top of the page. Currently requires manual installation in Chrome's developer mode. The tool is designed for users who frequently need to perform quick text lookups and customization.

Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
