The review
What it does
Ask Citelight a question and it searches, reads and answers with a citation on every claim. The distinctive part: any sentence it can't tie to a specific passage is shown faded, so you can see at a glance which parts of the answer are supported and which are the model filling gaps. Click a citation and it opens the source at the quoted passage.
Why we like it
This is the most honest research interface we've tested. It doesn't pretend to be more certain than it is, and the faded sentences become a to-do list for your own checking. Students, journalists and analysts in our community have adopted it quickly. Uploading your own PDFs to search alongside the web works smoothly.
Watch out for
- A citation proves a source says something, not that the source is right. Judge the source too.
- Paywalled material is invisible to it unless you upload it.
- The free tier caps deep searches at a handful per day.
