Most research writing still happens across too many tabs: a Word or LaTeX file in one window, a notebook in another, a reference manager in a third, and a general chatbot that has never seen the project. Papers AI, at papers.ai, is built as a response to that split. The official site describes it as an all-in-one research workspace that brings writing, data, references and code into the same flow, and says it is built by Overleaf, “the scientific writing platform trusted by over 25 million people worldwide.”
This guide is based on the Papers AI homepage, pricing page, terms and documentation, checked on 10 November 2026. It is a product explainer, not a review of every paper you might write in it, and it is not a shortcut for submitting work you have not read.
What the workspace is for
The homepage says Papers AI “brings your writing, data, references and code into the same flow, so you can follow the thought without rebuilding the context.” It lists the tab-switching it aims to replace: Word, Markdown, Jupyter, Zotero, Claude, ChatGPT and Python.
Three jobs sit at the centre of that claim. First, writing with a partner that can see the project, so you are not re-uploading files each time you ask a question. Second, running analysis and code next to the draft, so notebook outputs can become figures and tables without another export round. Third, keeping citations close: the site says you can cite from your library or pull from a reference manager.
The documentation describes a browser-based workspace that opens in any modern browser. You can keep work on your device or save it to the cloud to move between devices and share it. That local-or-cloud choice is repeated on the homepage under “Your work belongs to you.”
Local-first details that change how you should use it
Papers AI calls itself an offline-first workspace. Files live on your device and compilers run in your browser, unless you choose to save to the cloud for multi-device work or collaboration. The homepage says projects stay in local storage until you decide otherwise, and that LaTeX, Typst, MyST and Jupyter all run on your machine and work offline.
That is different from a chatbot you paste text into. It is closer to an editor that happens to include AI. The terms of use, published by Digital Science UK Limited (with a US affiliate, Digital Science & Research Solutions Inc., for some billing addresses), describe a web-based scientific editor for authoring, editing and collaborating on scientific documents. European users are given a London contact address; users outside Europe are given a Cambridge, Massachusetts address.
AI changes are described as something you control: you accept, reject or edit them. You can also bring your own model with an OpenRouter key, or point the app at a local model running on Ollama, LM Studio, vLLM or any OpenAI-compatible endpoint. If you connect your own key or model, the pricing page says that provider’s terms apply instead.
The same pricing page states that “Papers AI and its AI providers never use your papers or data to train AI models.” That is the company’s stated policy as of 10 November 2026; read the current terms and privacy notice if data handling is a deciding factor for your lab or publisher.
Free and Plus, side by side
The official pricing page listed two plans on 10 November 2026: Free at £0 and Plus at £10 per month, billed monthly and cancellable at any time. Taxes may be added depending on billing address, and the page notes that usage limits apply and that prices can change.
| Feature listed on the pricing page | Free | Plus |
|---|---|---|
| Monthly price (as of 10 November 2026) | £0 | £10, billed monthly |
| AI reads the whole project context | Included | Included |
| Daily AI usage allowance | Described as “generous” | 5× more, with longer conversations and in-depth analysis |
| Add your own local AI models | Included | Included |
| Bring your own AI with OpenRouter | Included | Included |
| Write in Word, Markdown, Typst and LaTeX | Included | Included |
| Run analysis in Jupyter notebooks | Included | Included |
| Reference management with auto-updating citations | Included | Included |
| Connect to Zotero, Mendeley and ReadCube | Included | Included |
| Export to PDF, DOCX and Markdown | Included | Included |
| Projects, real-time collaboration, offline work | Unlimited projects; collaboration and offline work included | The same |
Both plans include the core workspace. Plus is the plan to consider if you are hitting the free daily AI allowance or you want longer, more analytical conversations. It is not described as unlocking Word or LaTeX; those formats are listed as included on Free.
Collaboration without treating AI as a co-author
The homepage describes multi-user editing with “sub-50ms presence” in .tex, .docx and .ipynb files, threaded review with resolve, reopen and @mention, and a reviewable history in which every edit is attributed and reversible. That is ordinary scientific collaboration language, and it is the part of the product that most clearly comes from Overleaf’s background.
Use those tools the way you would use comments in a shared document. The AI can draft or point out a missing reference; you still decide what goes into the manuscript. The homepage example of the assistant noticing a TODO and a citation that is missing from refs.bib is the right kind of help: it checks the project you already have, rather than inventing a new paper around it.
A practical way to try it
Create one real project rather than a blank demo. Put the draft, the bibliography and one notebook or data file in the same workspace. Ask the AI a question that requires reading more than a single paragraph, such as an inconsistency between the methods section and a table. Accept only the suggestions you have checked against the source. If you are writing under journal or university rules about AI assistance, follow those rules; Papers AI does not replace them.
Papers AI is worth opening if your problem is context lost between tools, not if you are looking for a button that writes a paper from a title. The official site is clearest on that point: write, run and reason in one place, with the files remaining yours unless you choose to sync them.
