Unkwn42 is a research terminal for climate science. You enter a research idea and it returns a claim-level verdict: whether a specific paper already asserts your claim (it names the paper), or exactly how your claim differs from the nearest prior work, stated as a delta. It also surfaces the prior work it rests on (including papers filed under renamed terminology), how the terminology has drifted over time, the key researchers and institutions, and the publication trend. Every paper cited is a real retrieved record, never generated.

How does Unkwn42 help researchers?

Before committing months to an idea, a researcher can check in seconds whether it has already been done, and surface prior work that earlier searches missed because it was filed under different terminology. It maps the frontier around an idea so you can decide with full context instead of guessing.

Unkwn42 is for anyone in climate research checking a claim before committing months to it, defending a contribution to a reviewer or funder, entering an unfamiliar subfield, or making sure a known result has not already been done in the place they plan to do it.

Does Unkwn42 reject ideas that overlap with prior work?

No. It is not a pass or fail uniqueness test. Replication, extension, and doing a known study in a new place are legitimate research. The verdict has three states: Claimed (a specific paper already asserts the claim), Adjacent (the nearest work is distinguishable, with the delta stated), and Open (no paper asserts it). Even a Claimed result is information for a decision: what to match if replicating, or what to differentiate against if extending.

Will Unkwn42 invent or hallucinate citations?

No. Every paper cited is a real record retrieved from the literature, not generated. If the system cannot point to a specific paper, it does not make the claim. Grounding is verified in code before anything reaches you, and every result links to the source so you can check it yourself.

Reviewer 2 plays a hostile referee before you submit. Paste an abstract or a rough idea and it finds the papers someone could cite against your claim, ranks them by threat, states the attack a reviewer would make, and drafts a citation-grounded defence of how your work differs.

Why not use a general AI research assistant or Google Scholar?

General research agents answer across all of science; Unkwn42 does one question in one field and goes deep. Keyword search also fails silently when you do not know the words: a paper that already did your work can sit fully indexed under a term your subfield stopped using, and no search you would think to run will surface it. Unkwn42 expands your idea across renamed and drifted terminology to retrieve exactly that prior work.

There is a free plan with 3 checks a month across the Terminal and Reviewer 2, and Scoop Radar is included. Pro gives more usage for $9 a month or $79 a year. See https://www.unkwn42.com/pricing.

Finding out that your idea has already been done should take days, not months, and never a year in.

Key findings

Finding the prior work for an idea can take months, and some researchers only learn a year in that it had already been done.
Climate science sits where oceanography, ecology, hydrology, atmospheric physics and economics meet, so the same finding can live in two literatures under two names.
unkwn42 finds the closest existing work to an idea, including papers that use other words, says how yours differs, and tells you when our coverage of your area is thin.

I'm building unkwn42 because of my own dissertation.

During my data science degree, my supervisor gave me a topic that, it turned out, had more or less been done before. I spent an awful lot of time just finding the papers, and very little on the part that mattered: doing the research and writing it up.

Since then I've heard versions of the same story from other researchers, and theirs are worse. They find out that the idea, claim or angle they have been working on was already done, and they find out a year in.

I want what took me months to take days. I want people to find out on day one, not a year in, so that people with good ideas spend their time on what matters: the research itself.

A familiar feeling

You have an idea you're fairly sure nobody has had. Scholar says nothing obvious. Your supervisor shrugged in a good way. And there's still a small voice asking: is this new, or did I just not search the right words?

Why the worry is right

That voice is usually right to worry. Climate science is a crossroads of oceanography, ecology, hydrology, atmospheric physics and economics, and every field names things its own way. Take marine heatwaves. In the 438,284 papers we hold, no paper uses the phrase before 2016. It came into use that year and became the main term by 2019. Before then, the same events were often written up as warm anomalies. A finding can live in two literatures for years under two names, with neither citing the other. Keyword search can't find what you don't know to type.

What unkwn42 does

That gap is what unkwn42 is for. You describe your idea the way you would over coffee, and it comes back with the closest existing work, including papers that say the same thing in other words, a line on how the closest ones differ from yours, and a note on how well we cover your area, so you know when we're thin. If you're already writing up, Reviewer 2 reads your abstract like a hostile referee and lists the papers that could be cited against you.

What it gets wrong

It isn't finished, and it will miss things. When it does, there's a box under every result for the paper that should have appeared. Each one is traced back to where the search lost it, and the confirmed ones become tests the next version has to pass.

What I'll write here

Notes from the climate literature as we see it from the inside: ideas that have gone by different names, how much of the field we cover and where we're weak, what researchers tell me about checking prior work, and what unkwn42 gets wrong. The first is Renamed: before they were marine heatwaves.
