* open user register to any one who have access to your overleaf

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-21eb9305aad39ee5ca78fbf0db17aba5b9026342%2Fimage.png?alt=media" alt="" width="563"><figcaption><p>Register page</p></figcaption></figure>

#### Features 11: Learn Wiki

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro). You can see latest learn wiki from overleaf, but we don't own any copyright of those documents! We just download it from overleaf server the first time you enable this feature, and update periodically.

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-d7f199e42a011c88bf66ec9a52b8fbad1abfd7e9%2Fimage.png?alt=media" alt=""><figcaption><p>Wiki page</p></figcaption></figure>

#### Features 12: GitHub Sync

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro), also modified and fixed by [yu-i-i/overleaf-cep](https://github.com/yu-i-i/overleaf-cep).

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-1dea79a853c8a0eff3d01c5a37510ef670722181%2Fimage.png?alt=media" alt=""><figcaption></figcaption></figure>

#### Features 13: Python Runner

This feature is developed by overleaf official. You can run Python scripts in your browser.

It is built in and needs no configuration: open a `.py` file in a project and click **Run**. The script runs with Pyodide in the user's browser, so only Pyodide's built-in packages are available.

* The output pane below the editor shows what the script prints (the last 100 lines). Click **Stop** to interrupt a run. Each run starts a fresh Python, so nothing carries over from the previous run.
* Before each run, the project's text files are copied into the script's working folder, so the script can open them by their project path, e.g. `open('data/results.csv')`. Binary files such as images and PDFs are not copied.
* Files the script writes into that folder are saved to the project at the same path when the run succeeds, replacing a file with the same name. A failed run saves nothing. A run may save up to 50 files, 50 MB per file and 100 MB in total.
* Matplotlib has no display: save plots with `plt.savefig('figure.png')`, then include the image in your LaTeX document.
* Pyodide and its packages (such as NumPy, pandas, SciPy and Matplotlib) are served by your instance, so the browser does not need internet access. Packages installed with pip cannot be used.

#### Features 17: Reference Manager Integration

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro). Zotero integration was initially developed by [davrot](https://github.com/davrot) and [yu-i-i/overleaf-cep](https://github.com/yu-i-i/overleaf-cep); we reworked it with OAuth and added Mendeley integration (OAuth 2.0) in v6.3.0. You can:

* Link your Zotero and Mendeley accounts in Account settings.
* Import your personal library or a group library as a `.bib` file into your project.
* Refresh the imported `.bib` file at any time to keep it up to date.

See [Zotero Integration](/on-premises/configuration/overleaf-toolkit/integrations/zotero-integration.md) and [Mendeley Integration](/on-premises/configuration/overleaf-toolkit/integrations/mendeley-integration.md) for setup.

#### Features 18: Open in Overleaf API

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro), compatible with the "Open in Overleaf" API of overleaf.com. You can add an "Open in Ayakaleaf" link or button to your website, blog or template library, so visitors can open a LaTeX snippet, a remote file or a ZIP project as a new project in your instance with one click. Visit `/devs` on your instance for details, and see [Overleaf Import API](/on-premises/configuration/overleaf-toolkit/integrations/overleaf-import-api.md).

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-8447c9f1401acd56638047f84537688f45a14a04%2Fopen-in-overleaf-api-page.png?alt=media" alt="Open in Overleaf API page"><figcaption></figcaption></figure>

#### Features 19: GitLab Sync

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro) in v6.3.1 as an early preview (official release in v6.4.0). Like GitHub Sync, you can link a project to a repository on GitLab.com or your self-hosted GitLab, push commits from Overleaf and merge commits from GitLab. See [GitLab Synchronisation](/on-premises/configuration/overleaf-toolkit/integrations/gitlab-synchronisation.md) for setup.

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-b847afba2e782841fead949a1e1c49d771dceea5%2Fproject-synchronisation-settings.png?alt=media" alt="GitHub, GitLab and Dropbox in the account settings"><figcaption><p>Project synchronisation in the account settings</p></figcaption></figure>

#### Features 20: Dropbox Sync

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro) in v6.3.1 as an early preview (official release in v6.4.0), like Dropbox Sync on overleaf.com. Once a user links their Dropbox account, each of their projects appears as a folder in their Dropbox: changes in Overleaf are sent to Dropbox, and changes made in Dropbox come back to Overleaf. See [Dropbox Synchronisation](/on-premises/configuration/overleaf-toolkit/integrations/dropbox-synchronisation.md) for setup.

<figure><img src="https://2052729351-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FyLFrF2L1FakWXkhqpOnS%2Fuploads%2Fgit-blob-6c4244b0ede5f64a120cfd6181c3e2481e4d7c8f%2Fdropbox-sync-modal.png?alt=media" alt="Sync with Dropbox dialog in the editor" width="563"><figcaption><p>Dropbox sync status in the editor</p></figcaption></figure>

#### Features 21: MCP Server

This feature is developed by [ayaka-notes/ayakaleaf-pro](https://github.com/ayaka-notes/ayakaleaf-pro) in v6.3.1. Each project has an MCP server, so AI clients such as Claude Code, Codex, Cursor, VS Code or Gemini CLI can read and edit its files live, compile it, read the LaTeX log, download the PDF and answer comments. See [MCP Server](/on-premises/configuration/overleaf-toolkit/integrations/mcp-server.md) for setup.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://ayakaleaf-pro.ayaka.space/on-premises/readme/features-and-copyright.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
