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.
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.

Who hunted Lumi?
Lumi was hunted by Zac Zuo. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
