Caught three bot accounts spamming the same AI-written reply across multiple threads yesterday. The badge made it obvious — all scored under 20.

What MogSignal does

Six signals. One score.
Instant clarity.

Every username gets a trust score computed locally from six signals — no server round-trip, no account needed.

Inline trust badges

Color-coded score next to every username — green for trusted, amber for uncertain, red for bot risk. Works on new Reddit, old Reddit, and mobile web.

Bot & AI detection

Detects AI-generated prose (phrase density, entropy), fake usernames (random strings, number-spam), and bot posting patterns (velocity, burstiness).

Deleted comment recovery

Comments cached passively as you browse. When a mod removes or a user deletes, MogSignal restores the text with a clear "mod-removed" label.

Under 1ms per comment

All scoring runs locally in your browser. No network requests, no latency, no rate limits. Even threads with 500 comments score in milliseconds.

Community flags

Sign in with Google to flag accounts that slip past the local heuristics. Flags feed a shared bloom filter — your catch helps everyone.

Privacy by design

Phase 1 scoring touches zero external servers. No browsing history sent anywhere. Community features are strictly opt-in.

How it works

Three seconds to trust.

No account needed. Works the moment you open Reddit.

Install the extension

One click from the Chrome Web Store. No permissions beyond Reddit, no sign-in required to start.

Open any Reddit thread

Badges appear automatically next to every username. Green = trusted, red = bot risk. No button to click.

Hover for full breakdown

See each signal bar — username entropy, AI phrase density, account age, karma, posting velocity.

Under the hood

What goes into a score?

Username entropy

Random-string names, number-spam suffixes, and excessive special characters are red flags.

AI phrase density

2,000+ phrases from LLM output — "it's important to note", "delve into", "at the end of the day".

Account age

New accounts (under 30 days) with high activity are weighted differently from established accounts.

Karma velocity

Unusual karma-to-age ratios signal either vote manipulation or genuine viral content.

Posting burstiness

Humans post in bursts then go quiet. Bots post at mechanically consistent intervals.

Community flags

Accounts flagged by multiple community members get an additional penalty via bloom filter lookup.
