{features}
The home of unconstrained, free scientific writing
Create complex, impeccably formatted documents with ease. Collaborate with anyone, without paying per collaborator seat.
⚡
Free and unlimited
Compile in the browser or on your own machine, with no subscription and no queue.
👥
Collaborate with no per-collaborator cost
Invite whoever you want: we do not charge per collaborator seat.
🔒
Your data, your repository
The project lives in your browser and your repository. The server neither stores nor logs the content.
What you find inside the editor
Compiling in the browser
pdfLaTeX, XeLaTeX and LuaLaTeX in WebAssembly: nothing to install and no server minutes to pay for.
Engines and local agent →Real Git
GitHub and Codeberg: commit, push, pull, reset, conflicts and Git Blame right in the editor.
Smart editor
The VS Code editor, with autocomplete that understands your project, global search and document structure.
Project map
See the paper as a mind map: sections as branches and figures as leaves, with a click to jump to the text.
Comments and history
Comment threads, named milestones and a revision history with restore, per file.
Reference search
Ten sources (Crossref, OpenAlex, arXiv, DBLP and more) and the \cite with the BibTeX in your .bib in one click.
Jupyter notebooks
Open and run .ipynb in the browser, with Python, pandas, matplotlib and formulas, with nothing to install.
Python, tables and diagrams
Run scripts, see CSV as a table, write in Markdown and draw Mermaid diagrams in the same window.
{why free compilation?}
Compilation on your own machine: why pay to wait in queues?
Other editors put you in a queue or kill your compilation after 60 seconds with a timeout error to push expensive subscriptions. On NeoLeaf, the processing power is yours:
⚡
WebAssembly (In Your Browser)
100% client-side compilation: runs TeX Live directly inside your browser tab using WebAssembly (texlive-wasm / BusyTeX).
- Absolute privacy: your text is never sent to a remote server for compilation.
- Zero setup: open NeoLeaf and start compiling right away.
- Ideal for conference papers, reports, and Beamer presentations.
- Doesn't burn server quotas and doesn't rely on fast internet.
Native Default · Zero Install
💻
Native Local Agent (Extreme Speed)
Want instant compilation for large theses? The neoleaf-agent links the web UI directly to compilers installed on your computer (TeX Live, TinyTeX, or Tectonic).
- No time limits: compile 400-page documents with zero fear of timeouts.
- Leverages all CPU cores and RAM of your own machine.
- Native support for XeLaTeX, LuaLaTeX, BibTeX, and custom packages.
- Runs in the background with a single install command.

{templates}
Start from a ready-made template
Create a new project with the structure already in place. Templates added to the catalog show up here and when you create a project.
Scientific Article
Article with title, sections, math and figures, ready to edit and compile.
Technical Report
Report with chapters and sections, for lab work, projects and longer documents.
Presentation (Beamer)
Beamer slides: outline, sections and frames ready for your content.
After hitting compile timeout limits and being billed in dollars every time we wanted to add another student to the same paper, we switched to NeoLeaf. Compiling directly in the browser with WebAssembly and saving commits straight to GitHub is true academic freedom.
{plans}
Academic freedom shouldn't come with a monthly invoice
Compare NeoLeaf with traditional platforms that lock essential features behind paid subscriptions.
The Open Standard
NeoLeaf
$0 / forever
Everything you and your team need to produce high-impact science without restrictions.
- ✓ Unlimited collaborators on all projects
- ✓ Zero-cost compilation (WASM or Local Agent)
- ✓ Zero wait queue and zero 60-second timeouts
- ✓ Your data in your GitHub or Codeberg (no lock-in)
- ✓ Full version history via native Git

- ✓ Absolute privacy: nothing retained on third-party servers
Other Platforms
"Free" Plan (with strings attached)
The traditional free tier with artificial limits crafted to push paid upgrades.
- ✕ Only 1 collaborator (add your advisor and pay up)
- ✕ Strict compile timeout (compile error: timed out)
- ✕ Sluggish compile queues during peak submission hours

- ✕ Charge you to unlock history that Git provides for free
- ✕ Charge you to unlock extra CPU processing seconds
- ✕ If research funding is delayed, you lose your access
- ✕ Your research data remains trapped in their database

Who is behind NeoLeaf.Science
Tássio Virgínio
Professor, Researcher and Advisor
NeoLeaf.Science is created and maintained by Tássio Virgínio, who uses it every day to supervise academic work, scientific papers and theses. It was born from real needs: having control over your own files, not depending on compilation time limits, not paying per collaborator, and having the features I always wanted in an editor. I hope it is as useful to you as it is to me. If something does not work, or you have questions about how your data is handled, talk to me.
Your projects are yoursEach project is a repository in your GitHub or Codeberg account. If NeoLeaf goes offline, your files stay with you.
The server does not store your projectYour files stay in your browser and in your repository (GitHub or Codeberg). The server keeps only what is needed for you to sign in.
Compilation on your machineLaTeX compiles in your browser (WebAssembly) or in the local agent, with no queue and no time limit imposed by us.
{support}
Support NeoLeaf.Science
NeoLeaf.Science is a non-profit project. There are no paid plans, ads or per-collaborator limits, and it is free to use.
Keeping the site online has server and domain costs, besides the development hours. If NeoLeaf helps your work and you would like to contribute financially, any amount is welcome. Supporting is entirely optional and changes nothing about what you can use.
Support is made through Ko-fi, outside NeoLeaf. We do not receive or store any payment data.
