Show HN: A browser extension that decodes food labels for healthy eating

https://feedbun.com/?hn
2•fredwu•1h ago
Hi HN!

For the past while I've been building FeedBun, a browser extension that gives you health ratings and research summaries for food products while you shop online or while you look for cooking recipes.

I'm building this because I wanted this product and couldn't find anything similar - most tools I found either required barcode scanning or were limited to specific stores. I wanted something that works seamlessly across all websites. I even have some big features planned for the future.

Tech stack: Elixir/Phoenix via Petal Pro framework for the backend - this is my 3rd SaaS using Petal Pro which I'm also a contributor of.

What makes it unique in my opinion:

* Science-backed analysis: Our AI researches every ingredient against scientific databases and reputable sources and gives you plain English explanations

* Works anywhere: Amazon, Walmart, any grocery site - just click our extension while viewing a product (pages with ingredient info works better with more detailed research), no barcode scanning needed

* Health warning callouts on ingredients that might appear innocent but may have hidden risks

* A suite of personalisation features, such as allergy warnings, dietary preferences, with more to come

Looking for feedback on:

* Does the landing page resonate with you?

* Does the browser extension work well? Any bugs or glitches?

* How useful would this be for your grocery shopping or recipe hunting?

* What features would make this a must-have for you?

* Would you pay for this? If so, and assume the personalisation features mentioned on the landing page (such as allergy alerts, dietary preferences, etc.) are implemented, how much would you be willing to pay per month?

Any comments or feedback are appreciated!
