Warden reads the comments on a page and rewrites the hostile ones, so the argument survives and the abuse does not. It runs as you scroll, in place, with no separate dashboard to check.
Free tier: 10 rewrites a day, no card required.
What it actually does
"the housing shortage is a policy failure, though these parasites flooding in have made it worse"
"the housing shortage is a policy failure"
The complaint about housing is kept. The claim about a group of people is removed rather than reworded — that distinction is the whole design, and the thing most of the models we tested got wrong.
"nobody wants you here, do everyone a favour and end it already"
"I've got nothing useful to say to you"
When there is no argument underneath, Warden does not invent a polite version of the same wish. It refuses.
How it works
When a page loads, Warden collects the comment text you can see on it. Nothing from other tabs, nothing from your history, and no images.
Ordinary text is discarded before any judgement is made — on a normal page that is roughly two thirds of it. Only what survives that filter counts against your daily allowance.
What remains is sent to a large language model with a prompt written and tested for this one task. Anything it flags is rewritten in place, next to the comment that triggered it.
Three settings: attacks on people only, all hostility, or anything negative at all. You can change it at any time, and the page updates without re-reading anything.
What it is, plainly
Comment text is sent to DeepSeek, whose servers are in China, to be judged. It is not processed on your machine. We do not store the text of the comments we judge, and we never sell data. Read the privacy policy.
Warden runs on a general-purpose language model. What is ours is the prompt, the guard rails around it, and the test suite that keeps it honest — not the model weights.
It sometimes rewrites something that did not need it, and it can miss things. It is a filter you control, not a moderator, and the original text is always one click away.
Measured, not claimed
Those figures come from a 43-case internal test set, run repeatedly. It is a small set that we wrote ourselves, so treat it as evidence that the thing works rather than an industry benchmark. We publish the numbers we have rather than adjectives we cannot support.
Ten rewrites a day, no card. If you want more, Guard is £24.99 a month for 100 a day and Pro is £39.99 for 300.
