Where they pull apart

Pangram

Stands out: Third-party-tested detector with a free daily cap, image scans, and a self-serve developer API.

Watch out: Individual is 300,000 words per month. API credits start at $0.05 per 100 words on Pangram 4, billed separately from the $20 seat.

Not the right fit for

Schools that need LMS-wide unlimited seats only
Teams that want a detector with no free cap

Polygraf AI

Stands out: Transcribes interviews and scores AI-coached answers in under 2 seconds, aimed at Cluely, Yoodli, InterviewCoder, and Pickle.

Watch out: The hiring detector is demo-sold. Retail AI-detector plans exist for writing, but those are a different SKU from interview fraud.

Not the right fit for

Teams that want a self-serve interview SKU with a rate card
Buyers who only need a cheap writing detector
