AI that writes LaTeX
Draft a section, continue from the cursor, or rewrite, shorten, expand and fix a selection. Output is LaTeX that compiles, not markdown you have to convert.
An AI writing assistant, citations from 327 million OpenAlex works, and a real pdfLaTeX engine (TeX Live 2026) that runs on your machine, not in a queue.
No signup to start. You only sign in (email code, no password) when you compile, use the AI, or save.
What it does
No plugins, no local TeX install, no copying citations between three tools.
Draft a section, continue from the cursor, or rewrite, shorten, expand and fix a selection. Output is LaTeX that compiles, not markdown you have to convert.
An actual TeX Live 2026 engine compiled to WebAssembly produces your PDF locally. Real errors, real page breaks, real \ref numbers.
Search 327M scholarly works, press Cite, and the key lands at your cursor while the bibliography builds itself.
The assistant may only cite keys you added. Claims that need a source get a \todo{citation needed} instead of a made-up DOI.
Ask for a referee report on your draft: methodological, structural and citation problems listed before a real reviewer finds them.
Download the compiled PDF or the .tex source at any time. Drafts sync to your account and follow you across devices.
How it works
Type LaTeX with syntax highlighting, start from a template, or describe a section and let the assistant draft it.
Search OpenAlex from the sidebar. One click inserts \cite{…} and adds the reference.
Press Compile (or Ctrl+Enter). pdfLaTeX runs in your browser; the PDF appears beside your source, ready to download.
Where the data comes from
Scholarly works in OpenAlex, behind every citation search and paper page here.
Source: OpenAlex docs, read 21 Sep 2026.Articles on arXiv, whose identifiers resolve to readable pages on resea.org.
Source: arXiv statistics, read 21 Sep 2026.The pdfLaTeX distribution the editor compiles with, running as WebAssembly.
Engine: texlyre-busytex.Pricing
Writing, compiling and citing are free. The AI has a daily limit so the service stays up for everyone.
FAQ
No account is needed to start writing. You sign in with your email address only when you compile a PDF, use the AI assistant or save a draft to your account. We send a 6-digit code; there is no password and no payment step, and you can delete your account and drafts at any time.
It is a LaTeX editor with an AI assistant. It drafts, continues, rewrites, shortens, expands and proofreads sections, writes referee-style reviews, searches OpenAlex for sources, inserts citation keys, builds the bibliography, and compiles a real PDF.
Yes. Compilation runs an actual pdfLaTeX engine (TeX Live 2026) as WebAssembly in your browser. It is not an approximation and not a server queue. The first compile downloads the engine once; your browser caches it after that.
It covers the full loop: writing and revising with AI, citing from OpenAlex, and compiling a real PDF. You can also download the .tex source at any time and compile it anywhere else.
The assistant is instructed never to invent citation keys, DOIs or numeric results. Citation keys come only from papers you added from OpenAlex, and unsupported claims are flagged with a citation-needed marker for you to resolve.
The beta is free, with a daily AI request limit per account so the service stays available. A Pro plan is planned after launch, around $9 per month for heavier AI use.
Before you sign in, your draft is kept in your browser. After you sign in it is saved to your account, so it is there when you sign in from another device. Deleting your account removes your email and every draft immediately.
Open the editor and start typing. Sign in only when you want to compile, use the AI, or keep your drafts.
