# Welcome
This is where you'll find all the technical documentation for Ayakaleaf Pro, an on-premises and enhanced version of Overleaf based on Overleaf Community Edition.
### Overview of Overleaf
Overleaf is a collaborative LaTeX editor loved by researchers and tech teams. Their cloud version is available at [overleaf.com](https://www.overleaf.com/). It provides a full-featured online LaTeX editor. However, Overleaf Common (SaaS version) has numerous feature limitations, and you have to tolerate a ***10-second compilation time limit*** and expensive membership fees.
Although Overleaf offers an open-source community version (available on [GitHub: Overleaf](https://github.com/overleaf/overleaf)), it also has many limitations, for example:
{% hint style="warning" %}
Overleaf Community Edition is intended for use in environments where **all** users are trusted. Community Edition is **not** appropriate for scenarios where isolation of users is required because Sandbox Compiles are not available.
Without sandboxing, LaTeX compiles run with the same privileges as the container, allowing access to its filesystem, network, and environment variables. This creates a risk of data exposure or system compromise. Non-sandboxed compiles should only be used in fully trusted environments; for multi-user or production deployments, Sandbox Compiles are strongly recommended.
For more information on Sandbox Compiles see: [Sandboxed Compiles](/on-premises/configuration/overleaf-toolkit/sandboxed-compiles.md)

### Information and Price about Overleaf Server Pro
The Overleaf website only provides an entrance to contact support for Server Pro, so information about Server Pro is very limited. But based on the information we have collected in the community, the **quota for Server Pro is**:
* You need to purchase licenses for *at least* 10 people.
* A 10-person license costs about β¬3,477.61. (2024)
* For education, 20 users cost 2640 Euro per year, 50 users 6050 Euro, and 100 users 9963 Euro.
* Server Pro is only available in select regions (e.g., excluding mainland China).
Based on the information currently available, Overleaf Server Pro appears to cost around $300 per user per year, with a minimum purchase of 10 licenses, making it a very expensive option. Moreover, Server Pro offers significantly fewer features than Ayakaleaf Pro. We are deeply grateful to the community developers whose contributions over the years have made it possible for us to build Ayakaleaf Pro and ultimately surpass Overleaf Server Pro in both functionality and capabilities.
The following public records show documented Overleaf Server Pro purchases and pricing. Smaller U.S. contracts indicate annual costs of roughly $320β$370 per user. Large institutional agreements can receive lower per-user pricing. For example, the Max Planck Society's three-year agreement averages about β¬51 per user each year. Contract terms, support, and deployment scope may differ. These records are not an official Overleaf price list.

## 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.md?ask=&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.
