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.
The claim in §3 is stated twice — merge the two sentences.
“three regimes” asserts prior work without a reference.
Move the estimator definition before its first use.
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.
A real project — main.tex, refs.bib, figures, class and style files — compiled with a full TeX Live installation.
.bibA rich text editor for when the deadline matters more than the markup. What you see is what gets typeset.
Not a demo of one clever feature — the whole path, from template to the file you upload to the conference site.
Start on IEEE conference or journal, ACM, Elsevier, Springer, arXiv or MDPI — the real document classes, already installed, already compiling.
Full LaTeX builds with bibliography passes, rendered in seconds. The PDF sits next to your text, not behind a download button.
Invite collaborators as editors or viewers. If two people save the same file, PaperX tells you instead of quietly discarding a version.
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.
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.
PDF, DOCX, Markdown, HTML, or the complete project as a ZIP you can compile anywhere. Your work leaves as easily as it arrived.
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.
Structured critique on clarity, rigour, structure and evidence — for a passage or the full paper.
Tighten an argument or rewrite an awkward paragraph, with the academic register kept intact.
AI-detection and plagiarism screening, plus a reference check that verifies your citations.
Upload a finished PDF and get an editable, reviewable project back — no retyping.
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.
Type, cite, add figures, and watch the PDF update beside you. Invite your co-authors whenever you're ready for them.
Run AI review over the sections you're unsure about, apply what's useful, and export the submission-ready file.
No seats, no monthly fee, no trial that expires. Add balance when you want AI, and spend it a few cents at a time.
Everything you need to produce the paper. Requires an account; costs nothing.
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.
| Action | Standard | Premium | Pro |
|---|---|---|---|
| Review a selection or section | $0.125 | $0.30 | $0.50 |
| Enhance or rephrase | $0.125 | $0.30 | $0.50 |
| Full paper review | $0.30 | $0.60 | $0.75 |
| Import a PDF as a project | $0.50 | — | — |
Also priced per use: reference check $0.05 per reference; AI detection $0.10 and plagiarism screening $0.20 per 1,000 words. All amounts in USD. Your balance never expires, and every action shows its cost before it runs.

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.
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.
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.
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.
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.
Create an account and open a project in under a minute. No card, no subscription, nothing to install.
