A Rulebook lets you define structured rules to review documents systematically and flag discrepancies.
Once you set a rule, Zeno will check the document and highlight:
If the rule is passed
If the document needs to be reviewed
If the information is missing
Zeno reviews with visible reasoning and detailed citations, so you see not only the outcome but the rationale behind it.
Create your own Rulebook:
From the home page, click Rulebooks.
Click Add Rule.
Enter a title and a requirement for your rule. The requirement is a prompt that tells Zeno what to look for.
Click Save. The rule will save, so you an apply it to your document. You will see your saved list of rules on the left side of your screen.
To add more rules, click Add Rule in the top left and repeat the process.
Click Select Document to choose an existing file or to upload a new one to run the Rulebook on.
After confirming to run the Rulebook on the document Zeno shows:
Which rules passed.
Which require review.
Which were not found.
Results include Zeno’s reasoning and citations to specific pages in the document.
To run the same rulebook on another file, click Change Document in the top right and select or upload a new document.
