AI sidebar for reading papers, articles & PDFs. Clip highlights, chat with your research, and recall saved notes, all in one place. Chat with any PDF or research paper, get a summary in seconds, and save what matters into notes an AI actually remembers. If you're looking for an AI research assistant Chrome extension for reading papers, running literature reviews, and keeping your notes together, Constella puts summarizing, chat with PDF, clipping, and recall in one sidebar on every page.
✦ WHAT IS CONSTELLA? Constella is an AI sidebar for reading. Open a paper, article, or PDF and it's already there: ask questions, get a summary, explain a hard paragraph, clip the parts you want to keep. Everything you save becomes a personal research library you can chat with later — so the tenth paper you read connects to the first nine.
Ask questions about the paper you have open and get answers grounded in its text.
Decide in seconds whether a paper is worth your hour.
Most AI tools start from zero every conversation. Constella remembers every clip and note, so it answers from your research, not just the open web. Find the finding from last month. Explain the concept from the paper you saved. Build on what you've already read.
Open a paper on a journal site, a preprint in your browser, a PDF, or an article you're reading, and Constella is already in the sidebar. One click, no switching apps, nothing to upload.
Your clips and notes are yours to export or delete at any time. Constella does not train AI models on your data.
Install Constella and read papers faster without losing what you learned.
