# Reader



Your LLMs deserve better input.



Reader converts any URL to an **LLM-friendly** input with a simple prefix `https://r.jina.ai/`. Get improved output for your agent and RAG systems at no cost.



- Live demo: https://jina.ai/reader

- Or just visit these URLs https://r.jina.ai/https://github.com/jina-ai/reader, https://r.jina.ai/https://x.com/elonmusk and see yourself.



> Feel free to use https://r.jina.ai/* in production. It is free, stable and scalable. We are maintaining it actively as one of the core products of Jina AI.

## Updates



- **2024-04-15**: Reader now supports image reading! It captions all images at the specified URL and adds `Image [idx]: [caption]` as an alt tag (if they initially lack one). This enables downstream LLMs to interact with the images in reasoning, summarizing etc. [See example here](https://x.com/JinaAI_/status/1780094402071023926).



## Usage



### Standard mode



Simply prepend `https://r.jina.ai/` to any URL. For example, to convert the URL `https://en.wikipedia.org/wiki/Artificial_intelligence` to an LLM-friendly input, use the following URL:



https://r.jina.ai/https://en.wikipedia.org/wiki/Artificial_intelligence



### Streaming mode



Use accept-header to control the streaming behavior:



> Note, if you run this example below and not see streaming output but a single response, it means someone else has just run this within 5 min you and the result is cached already. Hence, the server simply returns the result instantly. Try with a different URL and you will see the streaming output.

```bash

curl -H "Accept: text/event-stream" https://r.jina.ai/https://en.m.wikipedia.org/wiki/Main_Page

```



If your downstream LLM/agent system requires immediate content delivery or needs to process data in chunks to interleave the IO and LLM time, use Streaming Mode. This allows for quicker access and efficient handling of data:



```text



Reader API:  streamContent1 ----> streamContent2 ----> streamContent3 ---> ... 

                          |                    |                     |

                          v                    |                     |

Your LLM:                 LLM(streamContent1)  |                     |

                                               v                     |

                                               LLM(streamContent2)   |

                                                                     v

                                                                     LLM(streamContent3)

```



Stream mode is also useful when the target page is large to render. If you find standard mode gives you incomplete content, try streaming mode. 



### JSON mode



This is still very early and the result is not really a "useful" JSON. It contains three fields `url`, `title` and `content` only. Nonetheless, you can use accept-header to control the output format:

```bash

curl -H "Accept: application/json" https://r.jina.ai/https://en.m.wikipedia.org/wiki/Main_Page

```



## Install



You will need the following tools to run the project:

- Node v18 (The build fails for Node version >18)

- Firebase CLI (`npm install -g firebase-tools`)



For backend, go to the `backend/functions` directory and install the npm dependencies.



```bash

git clone [email protected]:jina-ai/reader.git

cd backend/functions

npm install

```



## What is `thinapps-shared` submodule?



You might notice a reference to `thinapps-shared` submodule, an internal package we use to share code across our products. While it’s not open-sourced and isn't integral to the Reader's functions, it mainly helps with decorators, logging, secrets management, etc. Feel free to ignore it for now.



That said, this is *the single codebase* behind `https://r.jina.ai`, so everytime we commit here, we will deploy the new version to the `https://r.jina.ai`.



## Having trouble on some websites?

Please raise an issue with the URL you are having trouble with. We will look into it and try to fix it.
