Perspective API Alternative: When Toxicity Scoring Is Not Enough

Google's Perspective API is a free, well-known toxicity scorer, and a fine starting point. But it is text-only, has fixed attributes you cannot change, and does nothing for images, PII, or spam. Here is when you outgrow it and how Paxmod compares.

Content Moderation APIs

Perspective API, from Google's Jigsaw team, returns scores for a fixed set of toxicity attributes. It is genuinely useful for measuring how toxic a piece of text is, and it costs nothing. If all you need is a toxicity signal on English text, it may be enough.

The limits appear quickly in production. You cannot define your own rule, only the attributes Google ships. It does not moderate images. It has no concept of PII sharing or spam. And it is rate-limited in a way that suits research more than a live chat pipeline. Those gaps are where a policy-driven API earns its place.
