For people who read for a living
AI gives you answers.
SCL is your shortcut to understanding.
Your papers — hundreds or thousands of them — organised, searchable and explained in your first session, without moving a single file. Three million papers come already prepared. The AI runs locally, or anonymised. Nothing you own is uploaded. You keep your edge.

“My PDFs are a mess.”
Point SCL at your drive. It shows everything you already have in topic folders — organised automatically, by what the papers are about, not what their filenames happen to say.
Nothing moves. Not one file is relocated, renamed or touched.
- ▸ Condensed matter (412)
- ▸ Superconductivity (96)
- ▸ Topological phases (74)
- ▸ Machine learning (388)
- ▸ Methods & instrumentation (213)
- … your files, exactly where they were
“I can’t find anything inside them.”
One search box, across the full text of every publication you hold. Contents, not filenames. The paper you half-remember from 2019 is findable by the sentence you half-remember.
- 🔍 “flux pinning in layered” — 23 documents
- — ranked by relevance, opened at the matching passage
“I can’t possibly read it all.”
Every paper gets a faithful paraphrase at the depth you choose — expert, layman, or novice — and a question-and-answer panel for real interrogation: purpose, method, biases, what it actually claims. You stay the expert in the loop; the AI does the triage.
3,000,000 papers arrive already prepared. If a paper in your folder is one of the three million we have already processed — most of arXiv is — its paraphrases, links and analysis appear instantly, in your first session. Anything else, you select for processing and are told when it is ready. Your first ten minutes are discovery, not setup.
- Expert · Layman · Novice
- “The authors demonstrate that vortex lattices in …”
“I don’t know what I already have.”
SCL cross-links everything you hold. Open a paper and see the other papers on your own drive that bear on it — including the one you forgot you downloaded three years ago. A meaningful link between two ideas is evidence the AI actually understood the material, not just matched keywords.
- ↔ Kim 2021 — same phenomenon, different measurement
- ↔ Aoki 2017 — the theoretical framework this result tests
The arithmetic nobody says out loud
Publication volume grows every year. Your reading capacity does not. The gap between what your field produces and what any one person can read is not a personal failing — it is arithmetic. See yours:
Approximate volumes from arXiv’s public submission statistics (preprints only — journal-only publications are not counted, so the real number is higher).
“…but using AI means giving my work away.”
Every AI answer costs you something. What you have to hand over to get it is your Privacy Gap.
Your documents, your questions and your line of thinking — on someone else’s machine, under a policy that can change without you.
Content is stripped before anything goes out, so you can reach a frontier model when you need one. Less leaves — but something still leaves. We won’t pretend otherwise.
Your documents, your questions and your answers stay put. The only setting where the gap is actually zero — and the default we recommend. Check it yourself.
You are no longer choosing between a good answer and a private one. How the two modes work, and what we will not claim →
What it costs
Free keeps every feature. Paying buys speed and convenience — never access, never privacy. The whole price list fits on one screen →
Who it’s for
Researchers, engineers, graduate students, independent experts, inventors — people trained to read hard material and act on it. If your livelihood runs on actually knowing things, this was built for you.
Use the giants; don’t teach them your experience.
