Public alpha

A multiplayer LaTeX & Typst editor with a research knowledge base built in.

Read your sources, write claims in your own words, link them into a graph you understand, and turn that graph into a draft — without switching between a reference manager, a note-taking app, and a typesetting tool.

Write in LaTeX, or in Typst (new, in alpha) — both run on the same fast in-process compile loop with a live preview. The compiler keeps up as you type, multiple people can edit at once, and it's free.

From reading a paper to writing one

Each stage seeds the next, so you're never staring at a blank page.

Editor, references, and knowledge base

  • Incremental compile — about 4x faster than a full rebuild

    An incremental engine recompiles only what you changed. On real arXiv papers an edit reaches the preview in about 0.6 s, where a full rebuild of the same paper takes 2-3 s. Measured numbers and method on the comparison page.

  • Live preview as you type

    Editor beside a live PDF preview that updates on each edit, with compiler diagnostics reported inline.

  • Real-time multiplayer editing

    Multiple people edit the same project live over a collaborative (operational-transform) session — no per-seat cap on a project.

  • Knowledge graph of papers & claims

    One graph underneath everything: papers you import and claims you write in your own words, with typed relations between them.

  • Typst drafts

    Author drafts in Typst alongside LaTeX — the same fast in-process compile loop, live preview, and bibliography injection. Alpha: source-replace + preview works; structured block editing and \cite{} integration are pending.

Your references, where you write

Import papers from arXiv, Crossref, PubMed, and OpenAlex — or bring an existing Zotero library — and cite them by key straight from the editor. No separate reference manager, and no .bib file to keep in step by hand.

How reference management works →

Compiles about 4x faster than a full rebuild

KL studio recompiles only what you changed, so the preview keeps up with your typing instead of queueing a full pdflatex run. On real arXiv papers an edit reaches the preview in about 0.6 s, where rebuilding the same paper from scratch takes 2–3 s. The method and the numbers are published, and the baseline is one you can re-run yourself.
