Introduction
If your blog has comments, you have a moderation problem. Spam, toxic language, and promotional links can quickly overwhelm your inbox. Manually reviewing every comment takes time away from writing.
AI moderation tools can automatically filter spam, flag toxic comments, and approve genuine discussions so you barely have to think about it.
Step 1: Use Akismet for Spam Detection (Most Popular)
Akismet is the industry standard for blog comment spam filtering. It powers moderation for millions of WordPress sites.
- How it works: When a comment is submitted, Akismet checks it against a global spam database. It automatically catches 99% of spam comments before you even see them.
- Best for: WordPress users who get more than 10 spam comments per day.
- Free tier: Available for personal blogs. Paid plans for commercial sites.
Step 2: Try Perspective API for Toxicity Detection
Perspective API by Jigsaw (part of Google) uses AI to detect toxic language, harassment, and hate speech in comments.
- How it works: You connect the API to your commenting system. It scores each comment on toxicity level. Comments above a certain threshold can be automatically held for review or rejected.
- Best for: Sites with active community discussions that need to stay civil.
- Free tier: Generous free usage limits for small to medium blogs.
Step 3: Use ChatGPT for Manual Moderation (Zero Cost)
If you do not want to install plugins, you can use ChatGPT to help you review comments in batches.

FAQ
Can AI moderation replace human review?
Not entirely. AI sometimes flags genuine comments as spam (false positives). It is best to use AI as a first-pass filter and review the "flagged" queue manually once a week.
How do I keep the comment section civil without over-moderating?
Set clear community guidelines and publish them above the comment box. Use AI only for spam and toxicity. Let respectful disagreements through—they often generate the most valuable discussions.
