Toxic Post Blocker for Gravity Forms
Block toxic content in Gravity Forms post fields by running AI moderation directly in the visitor's browser before submission.
What it does
When you use Gravity Forms to let visitors submit posts, you risk receiving harmful or abusive content. Toxic Post Blocker checks Post Title and Post Body fields for toxic language before the form is ever submitted, keeping your site cleaner without manual review.
The add-on runs a BERT-based AI model entirely inside the visitor's browser using Transformers.js. No form content is sent to an external API, so there are no per-request fees and no third-party moderation service to sign up for. The form stays locked until every protected field passes the check.
You can adjust the toxicity threshold in Gravity Forms settings to match how strict you want moderation to be. If the model cannot complete a check for any reason, the form stays locked rather than letting potentially toxic content through.

Does this send form content to an external server?
No. The AI model runs entirely in the visitor's browser, so form content is never sent to an external moderation API.
Do I need an API key or pay per moderation request?
No. There is no moderation API key required and no per-request fee.
What happens if the AI model fails to load or complete a check?
The form stays locked and the submission is blocked until the check can be completed successfully.
