    AI images for Reddit — bypass subreddit AI bots and Hive moderation.

    Many subreddits run automod bots and Hive Moderation to auto-remove AI content. SynthGuard humanizes images so they pass both.

    How Reddit moderates AI

    Reddit's biggest art and photo subreddits use Hive Moderation or community-built bots that score uploads with publicly available AI detectors. Detection results in auto-removal.

    Recommended workflow

    1. 1Generate your image
    2. 2Humanize at /humanizer with the "Strict" profile
    3. 3Upload to Reddit

    Reddit's AI-content situation is decentralized. There's no platform-wide AI policy — instead, individual subreddits set rules and many enforce them with bots. r/Art, r/photography, r/EarthPorn and dozens of others auto-remove anything their bot flags.

    The most common bot stack is Hive Moderation's API plus a community-curated phrase blacklist. Hive's image classifier targets the standard signals: frequency-domain fingerprints, PRNU absence, EXIF anomalies.

    SynthGuard's image humanizer beats Hive in our testing when run with the strict profile. Use strict on Reddit because the bots are unforgiving — even a borderline score triggers removal.

    For long-form Reddit posts with embedded images, humanize each image separately. The /detector page is also useful: paste your humanized image there to verify it scores as human before posting.

    Browser-only means there's no service that could log your generation history if a moderator subpoenaed it. Your image lives only in your browser tab until you upload.

    Frequently asked questions

    Which subreddits use Hive Moderation?+

    Reddit doesn't publish the list. Assume any large art or photo subreddit does.

    Can community bots detect humanized images?+

    Most can't — they wrap public APIs which SynthGuard targets directly.

    Will my karma drop?+

    Removal doesn't reduce karma, but downvotes do. Quality posts get upvoted regardless.

    Is this against Reddit's TOS?+

    Reddit allows AI content site-wide. Subreddit rules are independent.
