Nutrimatic is a tool used for puzzle solving. It was created by Dan Egnor in 2009. The tool uses regular expressions and phrase searching on a database created from Wikipedia. Unlike other similar tools, Nutrimatic is unique in its weighting for known phrases, making it a very powerful tool for solving. The tool can be used to Wheel of Fortune answers in a puzzle with only a handful of letters.

The name Nutrimatic comes from The Hitchhiker's Guide to the Galaxy, where Nutrimatic is a type of tea. This itself is a reference to Tea, a now-defunct crossword helper tool that was used for word pattern matching.

The puzzle Nutraumatic from MIT Mystery Hunt 2021 notably involved a website called Nutraumatic, based on (and nearly identical in design to) Nutrimatic.
