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
Read between the lines
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
Spot the techniques that steer you
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
See what the text wants you to believe
Scans for 29 categories of bias including political, gender, racial, framing, and selection bias. Each finding includes evidence from the text.
Omissions
Notice what was left 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
Think deeper about what you read
Puts the article’s own argument or proposal to the test: its goals, feasibility, assumptions and alternatives. Straight reporting simply passes.
Legal Risk
Check legal soundness
Flags where the actions or proposals described could raise legal questions, and under which law, without passing judgement on anyone.
Moral Lens
Evaluate ethical implications
Assesses content against 16 widely shared moral principles including dignity, honesty, equality, justice, and freedom.
Scientific Assessment
Separate science from pseudoscience
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
Get up to speed fast
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
Learn from the past
Finds historical precedents for current events. Understand patterns, draw parallels, and learn from how similar situations played out.
Neutral Rewrite
Read it de-spun
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
The fun one
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 analysesAn 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 verdictEvery 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 Scientific. You pay only for the models that actually run; ones already cached for the article join free.
