Lemma runs your draft past a panel of AI reviewers — surfacing the weak claims, citation gaps and LaTeX errors a referee will pounce on — inside a real editor that compiles to PDF. Fix what they’ll attack while you still can.

The obvious baseline is missing. You never benchmark against a top-k mixture-of-experts. Every reviewer expects it — it will be the first question asked.
Strong idea, thin evidence. §3 reports a single seed. Add variance over ≥5 seeds and a significance test before this can clear review.
Undefined reference. \ref{fig:results}doesn’t exist — you likely meant \ref{fig:arch}. Lemma fixes it in one click.
Everything happens in one workspace — no copy-pasting into a chatbot, no switching tabs to compile.
A real CodeMirror 6 editor with syntax highlighting, autocomplete and a live document outline — or flip to Rich Text and edit the rendered paper directly.
Summon the AI companion: simulated peer review, a weaknesses pass, citation checks, related-work finding, and one-click LaTeX fixes — all grounded in your actual document.
Compile to a polished PDF in the cloud — no TeX install, no setup, no waiting on a build server. Your paper, render-ready in seconds.
Not a generic chatbot bolted on the side — a panel of focused tools that read your whole project and act on it.
Four simulated reviewers debate your draft and return a verdict, scores, and specific objections.
The harshest read of your argument — gaps, overclaims, and the holes a reviewer will jump on.
Detects broken refs, missing packages and syntax errors — and applies the fix with one click.
Concrete suggestions to sharpen framing, strengthen experiments and tighten the narrative.
Surfaces the papers you should be citing — and the ones a reviewer will ask why you didn’t.
Flags uncited claims, unused references and mismatched keys between your text and .bib.
Paste the reviews you got back. It drafts a structured, point-by-point rebuttal plan with you.
A streaming chat that already has your full document in context. Ask anything, get grounded answers.
CodeMirror 6 under the hood — plus a Rich Text mode that renders headings, math, images and citations inline, so you can edit the paper as it reads.
You’re trusting Lemma with research nobody has seen yet. We treat it that way — your drafts are never training data, and Lemma reviews your paper without ever writing it for you.
Your manuscripts are not used to train any model. Reviews run on your text and are not retained beyond your project.
Projects are visible only to you and the collaborators you explicitly invite — no public listing, no indexing.
Remove a project and its entire review history permanently, whenever you want. It’s your work to take back.
Lemma critiques, finds holes and checks citations — it won’t author your paper. The ideas and the prose stay yours to defend.
Every tool unlocked from the first minute of your trial — the full reviewer panel, all 8 analyses, the editor and cloud compile. Pick monthly, or save with annual.
Full access, billed month to month.
Billed $108 yearly. Best for regular writers.
For groups and departments writing together.
Open a project, paste your draft, and let the companion tear it apart — kindly — while there’s still time to fix it.
