Lumi - Read smarter, not harder

Lumi is an AI reading experiment from Google's PAIR. Instead of summarizing, it adds a lightweight AI layer directly on top of arXiv papers. It highlights main points in the source text, makes references clickable, and lets you ask contextual questions about any selected text or image.

Hi everyone!

Lumi is a new experiment from Google's PAIR team that integrates AI directly into the paper-reading process.

The core idea is that it doesn't read the paper for you, it reads with you. It highlights key points on the original text, not in a separate summary. You can also select any text or image to ask questions right in context.

This approach turns reading an paper from a static task into a fluent, interactive exploration. The interaction logic here is something many productivity tool teams should really study.

Currently, it's focused on arXiv papers. But the project is fully open-source under Apache 2.0, so developers can get in there and adapt it for their own needs.

@zaczuo This is such a thoughtful approach to augmented reading and open source makes it exciting.

can i use this to read some novel ?haha

It seems to extend beyond academic papers.

@onlyyoulove3 Same, as a novelist, I really wish there was an app that could help me break down the content of other novels as inspiration or a resource library.

too bad I kept getting Error: Paper has a non-exclusive license and cannot be processed.

FYI I tried to read the Cat paper, and the Attention paper

Congrats on your launch 🤝this is such a refreshing approach to AI-assisted reading 👏. I love that Lumi focuses on reading with you instead of replacing the process entirely. Since it’s open-source, are there any plans to make Lumi compatible with other research databases beyond arXiv?

can I read a novel?

can my son use it to prepare for school lessons?

Lumi from Google's PAIR team looks incredibly useful for researchers! The ability to ask contextual questions about arXiv papers is brilliant. How does Lumi handle complex mathematical notations and formulas? Can it explain proofs step-by-step?

wow nice, excited to try it out

This will be hugely useful for my personal research goals.
