NyNeon is a growing collection of free online tools, plus a small blog. The idea is simple: we make useful things that are easy to use. Everything works in your browser, so you never need to sign up or install anything.
Because all content is in English, NyNeon works for anyone, wherever you’re from.
Who runs NyNeon
NyNeon is built and run by Noyon. It is a one-person project, not a company. The first tools came from everyday problems, like trying to compare Danish supermarket offers without reading eight different leaflets in Danish.
The goal is to build tools that save you from checking many websites to get one answer, and to keep them free.
Free tools
Some of the tools you can use today:
- Supermarket Offers Denmark: search current offers from eight Danish supermarkets in one place, in English.
- Recall Check: search US recalls for food, products and cars across official sources.
- Free VIN Checker: decode a US VIN and see open safety recalls.
- US No Tax on Tips & Overtime Calculator: estimate the deduction for your state.
- Image Background Remover, Image & PDF Tools and PDF to Markdown Converter: quick file jobs without extra software.
- QR Code Generator, What Is My IP and Typing Practice.
- AI Text Detector (beta): check whether a text may be AI-written.
You can find them all on the tools page. New tools are added over time, so check back now and then.
Where the data comes from
Each tool names its source. The supermarket tool shows current offers from Netto, Rema 1000, Føtex, Lidl, Bilka, 365discount, Spar and Meny. The offer data comes from ShelfAtlas, and our site updates it automatically every night. The recall and VIN tools use official US government data from NHTSA, CPSC, FDA and USDA.
Offer prices only last for a limited time and can vary between stores, so always check the price in store before you buy. For anything important, such as a recall or a tax amount, confirm the result with the official source.
NyNeon has no connection to any of these supermarkets or agencies, and they don’t endorse the site.
The blog
On the blog, we write practical guides around the tools and the problems they solve. We keep every post clear, so you get the useful part without the fluff.
How the site is funded
All tools are free. To cover hosting and data costs, the site may show ads. Ads never change what a tool shows you. See the Privacy Policy for how data and cookies are handled.
