Research writing workspace

Write your paper, compile it, and polish it — all in one place.

PaperX is an online workspace for academic writing. Choose full LaTeX with live PDF compilation, or a familiar Word-style editor when you'd rather not write code. Start from a publisher template, work with your co-authors, and call on AI review right where you're writing.

Writing, compiling and exporting are free No subscription — AI is pay-per-use Nothing to install
One workspace

Two ways to write. Same project, same output.

Some papers want LaTeX. Some want a page you can just type on. PaperX gives you both, and either one ends in a properly typeset PDF.

LaTeX editor

A real project — main.tex, refs.bib, figures, class and style files — compiled with a full TeX Live installation.

  • Live compile with the PDF beside your source
  • Click a line in the PDF to jump to the source that produced it, and back
  • Real compiler errors pointing at real line numbers
  • Citation and reference autocomplete from your own .bib
  • Import an existing project as a ZIP and keep working

Word-style editor

A rich text editor for when the deadline matters more than the markup. What you see is what gets typeset.

  • Headings, lists, tables, figures and equations without syntax
  • Same publisher templates, same compiled PDF
  • Export to DOCX when a co-author or journal asks for Word
  • Built-in spell-check as you type — free, no AI charge
  • The same AI actions, on any passage you select
What's included

Everything a paper needs between blank page and submission.

Not a demo of one clever feature — the whole path, from template to the file you upload to the conference site.

Publisher templates

Start on IEEE conference or journal, ACM, Elsevier, Springer, arXiv or MDPI — the real document classes, already installed, already compiling.

Compile and preview

Full LaTeX builds with bibliography passes, rendered in seconds. The PDF sits next to your text, not behind a download button.

Co-authors, safely

Invite collaborators as editors or viewers. If two people save the same file, PaperX tells you instead of quietly discarding a version.

Version history

Every save is snapshotted. Read any earlier state, compare it with today's, and restore it — the restore is itself a version, so nothing is ever lost.

Project-wide search

Search and replace across every file at once, plus an outline that lets you jump — or send a whole section to AI review — in a click.

Export without lock-in

PDF, DOCX, Markdown, HTML, or the complete project as a ZIP you can compile anywhere. Your work leaves as easily as it arrived.

AI assistance

A reviewer's read, before a reviewer reads it.

Select a sentence, a section, or the whole document. The feedback comes back in the editor, next to the text it's about — not in a separate report you have to reconcile by hand.

Review

Structured critique on clarity, rigour, structure and evidence — for a passage or the full paper.

Enhance & rephrase

Tighten an argument or rewrite an awkward paragraph, with the academic register kept intact.

Integrity checks

AI-detection and plagiarism screening, plus a reference check that verifies your citations.

Bring an existing paper

Upload a finished PDF and get an editable, reviewable project back — no retyping.

You choose the engine per action — Standard, Premium or Pro. Run a cheap pass while you draft, spend more on the section that decides the review. The price is shown before you spend anything.
Getting started

Three steps to a compiled paper.

1

Create a project

Pick your publisher template and your editor — LaTeX or Word-style. Or drop in a ZIP, or a PDF of a paper you've already written.

2

Write and compile

Type, cite, add figures, and watch the PDF update beside you. Invite your co-authors whenever you're ready for them.

3

Review and submit

Run AI review over the sections you're unsure about, apply what's useful, and export the submission-ready file.

Pricing

The editor is free. You pay only for AI.

No seats, no monthly fee, no trial that expires. Add balance when you want AI, and spend it a few cents at a time.

Always free

Write & publish

Everything you need to produce the paper. Requires an account; costs nothing.

  • Unlimited projects in both editors
  • LaTeX compilation and PDF preview
  • All publisher templates
  • Co-authors, version history, project search
  • Spell-check as you type
  • Export to PDF, DOCX, Markdown, HTML, ZIP
Pay per use

AI assistance

Charged per action, from your wallet balance. Pick the engine that fits the job — Standard for routine passes, Premium or Pro when the section really counts.

Questions

Before you start.

Do I need to know LaTeX?

No. The Word-style editor produces the same typeset PDF from the same publisher templates, with no markup at all. If you do know LaTeX, the full project is there — your own class files, packages and bibliography included.

Is anything really free, or is it a trial?

Really free, with no time limit. Writing, compiling, previewing and exporting cost nothing and always will — they just need an account. Only the AI actions draw on a balance, because each one calls a language model that costs us money to run.

Can I bring a paper I've already started?

Yes. Import a LaTeX project as a ZIP and keep writing, or upload a finished PDF and get an editable project back. Exports go the other way just as easily, so you're never stuck here.

Who can see my work?

Only you and the collaborators you invite, each as an editor or a viewer. Your files are stored in your own project space, and AI actions run only on the text you explicitly send.

Which journals and conferences are supported?

Templates ship for IEEE (conference and journal), ACM, Elsevier, Springer, arXiv and MDPI, all using the publishers' own document classes. Any other class file works too — upload it with your project and it compiles.

Your next paper starts on a blank page. Make it a compiled one.
