About Benchcraft
JB Codex publishes Benchcraft, a collection of tools for field operators, shop owners and office teams. Each tool takes a specific job from sample inputs to a result you can check and use.
How an answer is made
Each worked guide uses the same inputs and rules as its calculator. The examples are fictional. Each guide links to the video that inspired the application and explains what Benchcraft adapted.

On the site library, we count tool-finder uses, tool links opened and checkout clicks by broad source, such as search or ChatGPT. The counts contain no names, visitor IDs, queries, referring URLs or calculator inputs. A visit with no identifiable referrer is counted as direct. A click is separate from a confirmed payment. The counter respects Global Privacy Control and Do Not Track.
