BiasChecker.ai

See through the spin in any article or video

A Chrome extension that reads along with you. One click, and a panel beside the article or YouTube video you are on gives you an expert reading of it: the slant and what is left out, whether the argument and the science hold up, the legal and moral angles, the background, and a synthesis of it all. Nothing to copy or paste.

The extension analyses the article or YouTube video you are on, in one click, nothing to copy. The website works with text of your own. One account, plan and credit balance covers both.

How it works

1 · One click, any page

Click the extension icon on any article or YouTube video — news sites, blogs, anywhere. No copy-pasting, no new tabs.

2 · Pick your lens

Results appear in a side panel with thirteen analysis tabs — from bias and persuasion to synthesis, an analyst's report built from the other analyses.

3 · Read side by side

Every finding about the writing cites the exact passage it comes from, so you can check the analysis against the article as you read.

Want to check your own writing, a transcript or a PDF, or not reading in Chrome on a computer? Paste the text on the analyse page. Every analysis runs there too, and what you paste stays private to your account.

Thirteen expert lenses

Ever wish you could get an expert opinion on that article you just read? Now you can. Uncover hidden assumptions. See what the evidence actually supports and where the science gets speculative. Get a legal take, a moral perspective, or discover if history has seen this before — and how it played out.

Spot the slant

Is it slanted, and how is it working on you?

Intent Analysis

What the text says, and what it wants you to conclude

Exposes the gap between what a text literally says and what it steers you to conclude — and includes a concise summary of the piece. Cuts through spin to show the real message.

Persuasion

The persuasion techniques the writing uses, named

A focused lens on 8 persuasion techniques, named only where the writing clearly performs them — a deliberately narrower view than the full Bias Analysis.

Bias Analysis

Which way the writing leans, with the lines that show it

Scans for 29 categories of bias including political, gender, racial, framing, and selection bias. Each finding includes evidence from the text.

Omissions

The facts and viewpoints the article leaves out

Surfaces the facts, context, perspectives, and counterpoints a well-informed reader would expect — but the article leaves out. A second model checks the claims against the article before you see them.

Check the substance

Does it hold up?

Critique

Whether the argument holds up, and where it fails

Tests whether the article’s argument, or a plan it reports, holds up: what it argues, where it fails, and a better approach. Straight reporting simply passes.

Legal Risk

Where the actions reported could raise legal questions

Flags where the actions or proposals described could raise legal questions, and under which law, without passing judgement on anyone.

Moral Lens

How the actions reported measure against shared moral principles

Assesses content against 16 widely shared moral principles including dignity, honesty, equality, justice, and freedom.

Scientific Assessment

Whether the scientific claims stand up

Detects factual errors, pseudoscience, cherry-picked data, misrepresented evidence, and causal fallacies in scientific claims.

Get the context & extras

What is the fuller picture?

Background

What the story is about and how it got here

Builds the context around a topic: what it is, how it developed over time, and where things stand now — orientation for a reader new to the story.

Historical Parallels

When this has happened before, and how it ended

Finds historical precedents for current events. Understand patterns, draw parallels, and learn from how similar situations played out.

Neutral Rewrite

The article rewritten neutrally, and shorter

The article rewritten neutrally and more briefly. It only removes, never adds a fact, so you can check the shorter version against the source.

Roast

A comedian’s take on the article

A warm, witty comedian’s take on the article — a punchy verdict and a few standalone jokes about its most roastable details. Pure entertainment.

Then let it all come together

Synthesis

Built from your other analyses

An analyst’s report, built from your other analyses

Writes an analyst’s report from your other analyses instead of reading the article again: a one-sentence verdict on what the piece is doing to its reader, the findings connected into one story, what checks out, and what to verify. It always rests on Bias, Persuasion, Intent and Omissions. Analyses you already have are reused free, any that are missing are listed with their cost before anything runs, and the report itself is billed like any other analysis.

Don't trust one AI

Consensus

Several AIs, one verdict

Every model has its own blind spots — agreement between rival models is the strongest signal an analysis can give.

Press Consensus beside the model picker and models from at least three different makers each analyse the article. A separate model merges what two or more of them found into one result, and what only one model saw is shown separately with its name. If they agree on nothing, the result says so. Offered on Bias, Persuasion, Legal, Moral and Science. You pay only for the models that actually run; ones already cached for the article join free.
