Low carb calculator?

There exists a mfp user who wrote and offers a downloadable chrome extension which tracks net carbs. I'm trying to remember his name. Maybe if you do a search in the forums for "chrome extension" you can find it. I downloaded it a few weeks ago and you can look at my food diary to see how it displays carbs and (net carbs).

Here's one, but it's not the one I'm looking for. https://github.com/Surye/mfp-keto-userscript

Actually, many people have asked myfitnesspal to display net carbs, and mfp has not done so, not on the free side, not on the premium side.
