Show HN: Nerdulator – put something in, get everything out (no AI)
Nerdulator is a web-based tool that analyzes user input to identify its type and generate comprehensive data without using artificial intelligence. It employs deterministic parsers and lookup tables to calculate conversions, encodings, and mathematical properties for various data formats. The platform ensures consistent and verifiable results by computing all figures at request time rather than relying on machine learning models.
- ▪Nerdulator uses a deterministic parser with regular expressions and lookup tables to identify input types such as numbers, dates, and IP addresses.
- ▪The tool features 22 distinct engines that handle tasks ranging from unit conversions and color analysis to algebraic solving and chemical equation balancing.
- ▪All calculations are performed at request time using exact arithmetic, ensuring that the same input always produces the same output without AI intervention.
- ▪The platform supports a wide variety of data types including IPv4/IPv6 addresses, UUIDs, musical pitches, and geometric shapes.
- ▪Derived values from the analysis are linked to new pages, allowing users to explore related data such as color complements or date navigation with a single click.
