Check this text: 'Our product is 50% faster and always works.'

The scan found issues: '50%' lacks a citation, 'faster' lacks a benchmark, and 'always' lacks a qualifier.

Is this claim substantiated: '9 out of 10 users prefer us.'

No, the numeric claim '9 out of 10' is missing a source or citation marker.

Analyze this for comparative claims: 'Our software is more efficient than the industry standard.'

The claim 'more efficient' was flagged because it does not specify which industry standard is being used as a benchmark.

It identifies unsupported numeric claims, comparative statements without benchmarks, and absolute promises lacking qualifiers using tools like `unsupported_numerics_check`.
