Know first, believe later

Don't let others control your thoughts.

Gujob is a calibrated manipulation detector for online text. Highlight a Reddit post or comment and we'll tell you whether it's ragebait, a scam, a concern troll — or whether the signal's just too weak to call. Every verdict comes with the evidence it's based on.

How it works

A staged pipeline, not a single black box.

We don't ask one model "is this manipulative?" and call it a verdict. Each analysis runs through five quiet stages designed to fail safely when the signal is weak.

01 / Heuristics

Cheap signals first

Lexical patterns, structural tells, and known-tactic templates run before any model call.

02 / Model

Structured-output classifier

A schema-validated call returns a verdict, tactic labels, and candidate evidence spans — never a free-form answer.

03 / Evidence verify

Spans must exist in the text

Quotes are checked against the source. Hallucinated evidence is dropped before you ever see it.

04 / Calibration

Confidence that means something

Raw scores are remapped against held-out labeled data so a "70% confident" verdict is right about 70% of the time.

05 / Abstain gate

"Unclear" is a feature

When confidence or evidence is weak, we return unclear instead of guessing. That's the point.

06 / Adjudicator

Second look on close calls

When two reviewers disagree, the disagreement surfaces in the card — so you know when to apply your own judgment.

What we don't do

Privacy is a feature, not a setting.

Read your feed in the background — Gujob only sees text you explicitly select and click Analyze.
Collect your username, votes, comments, the URL of the page, or your browsing history.
Use your text to train models unless you explicitly opt in — and you can revoke that any time.
Run cookies, fingerprints, advertising IDs, or third-party trackers on the page.
Sell data. Ever.

The full breakdown — what's stored where, for how long, and how to delete it — lives on the Privacy page.

Feeling overwhelmed by the noise? You're not imagining things.
