EyeSift vs Originality.ai
Both stand on ai detection software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Choose EyeSift if you want browser-based screening and writing tools on a free plan without signup. Its broad checks and local processing may suit quick reviews, but high-stakes decisions call for draft and source checks with human judgment. Look elsewhere if you need full C2PA signature verification or SynthID decoding.
