This is a Sigil plugin for generating image alt text, and it was created 100% using Antigravity. Antigravity (
https://antigravity.google/) is an AI development tool provided by Google that allows you to use Gemini and Claude.
My Python skills are basically at the "Hello World" level—I know absolutely nothing beyond that.
I was able to complete this plugin using the initial 1,000 credits provided with a Gemini Pro subscription. The core development, including drafting the requirements, took about an hour (the actual code generation took about 10 minutes), and it took roughly 3 to 4 days to reach the current version by refining it based on real-world usage. Any inconveniences I encountered were not the AI's fault, but rather because I hadn't included those specific needs in the requirements until I actually started using the tool.
Beyond this, I have also used AI to create several other plugins for my personal workflow, such as a Dictionary Linker, an ID Insertion plugin, an LOT plugin (a modified version of LOI), Thorium Reader (
https://www.edrlab.org/software/thorium-reader/, for accessibility checks), and Vivliostyle Viewer (
