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.

- 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.
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 is useful when you find that the standard mode provides an incomplete result. This is because streaming mode will wait a bit longer until the page is fully rendered. Use the accept-header to toggle the streaming mode:
curl -H "Accept: text/event-stream" https://r.jina.ai/https://en.m.wikipedia.org/wiki/Main_Page
The data comes in a stream; each subsequent chunk contains more complete information. The last chunk should provide the most complete and final result.
For example, compare these two curl commands below. You can see streaming one gives you complete information at last, whereas standard mode does not. This is because the content loading on this particular site is triggered by some js after the page is fully loaded, and standard mode returns the page "too soon".
curl -H 'x-no-cache: true' https://access.redhat.com/security/cve/CVE-2023-45853
curl -H "Accept: text/event-stream" -H 'x-no-cache: true' https://r.jina.ai/https://access.redhat.com/security/cve/CVE-2023-45853
Note:
-H 'x-no-cache: true'
is used only for demonstration purposes to bypass the cache.
Streaming mode is also useful if your downstream LLM/agent system requires immediate content delivery or needs to process data in chunks to interleave I/O and LLM processing times. This allows for quicker access and more efficient data handling:
Reader API: streamContent1 ----> streamContent2 ----> streamContent3 ---> ...
| | |
v | |
Your LLM: LLM(streamContent1) | |
v |
LLM(streamContent2) |
v
LLM(streamContent3)
Note that in terms of completeness: ... > streamContent3 > streamContent2 > streamContent1
, each subsequent chunk contains more complete information.
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:
curl -H "Accept: application/json" https://r.jina.ai/https://en.m.wikipedia.org/wiki/Main_Page
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.
git clone git@github.com:jina-ai/reader.git
cd backend/functions
npm install
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
.
Please raise an issue with the URL you are having trouble with. We will look into it and try to fix it.
