From a rough idea
to a rigorous paper.
MathPaperAI helps mathematicians and scientists structure, draft and refine their work — with explanations, fact-checking and rewriting grounded in real ArXiv sources. Calm, precise, and entirely in your hands.
Free & open-source — AI access is configured by the deployment.
On the Convergence of Adaptive Spectral Methods
A. Author — Draft v7 — compiled just now
Theorem 2.1.
∫X |fₙ − f|² dμ → 0 as n → ∞.
Check: Logic holds — dominated convergence applies since |fₙ|² ≤ g² is integrable.
The toolkit
Everything a manuscript needs, nothing it doesn't
Each tool lives exactly where you write — one selection away, never in the way.
AI section scaffolding
Turn a title and a one-paragraph idea into the structure a reviewer expects — introduction, results, proofs — ready to fill in.
Explain, check & improve
Select any sentence for a rigorous explanation, a logical and factual check, or a cleaner, more precise rewrite.
ArXiv-grounded sources
Search ArXiv without leaving the editor and add papers straight to your references and reading list.
Formula workbench
Extend, simplify, solve or sketch a proof for any formula in place — the algebra stays under your control.
Version history
Every meaningful change is snapshotted locally. Compare versions and roll back without ceremony.
Local-first by design
Your working copy lives in your browser. Cloud backup happens only when you explicitly request it, and export always stays available.
The workflow
Three steps from blank page to draft
A calm, focused workflow — no busywork between you and the writing.
Describe your paper
Give it a working title, a type and the core idea. That seed is enough to get started.
Draft with assistance
Write section by section. Ask for explanations, checks and rewrites exactly where you need them.
Ground and refine
Pull in ArXiv sources, tighten your prose, and shape a manuscript you can submit.
Privacy, seriously
Your unpublished work is nobody's business
Research in progress is sensitive by nature. MathPaperAI remains local-first: your working copy lives in this browser, and a cloud copy is created only when you explicitly back it up. Private-beta accounts protect access; we do not run advertising or analytics tracking.
The details, in plain language: privacy policy.
Invite-only account, no tracking
Private-beta access uses essential sign-in cookies. We run no advertising or analytics tracking.
Local first, cloud by choice
Your working copy stays in the browser. Only the paper backups you explicitly start are stored in the cloud.
AI only when you ask
Text is sent to OpenAI only for the action you trigger. Use the beta allowance or keep your own API key in an encrypted browser-session cookie.
Leave anytime
Export anytime. Browser data and cloud copies can be deleted independently.
Questions
Asked before you had to ask
Do I need an account?
Yes during the private beta. Access is invitation-only, and the account protects your cloud copies. Your active working copy still stays in this browser until you explicitly back it up.
Where does my writing go when I use an AI action?
Only when you explicitly trigger an action (explain, check, improve, search…), the relevant text is sent to the OpenAI API to generate the response. Nothing is sent in the background, and we never store your text on our servers.
How is OpenAI access configured?
Choose the MathPaperAI beta allowance or bring your own OpenAI API key. A personal key is encrypted in an HTTP-only cookie for this browser session, never added to cloud backups, and used only for the AI actions you start.
Is it only for mathematics?
Mathematics is the home turf — theorem environments, formula tools, ArXiv search. But the workflow (structure, draft, check, refine) works just as well for physics, computer science and other quantitative fields.
Can I trust the AI's checks?
Treat them as a sharp second reader, not a referee. The checks catch logical gaps, unclear claims and sloppy phrasing remarkably well — but the mathematics remains yours to verify.
