Constella: AI Paper & Research Assistant

AI sidebar for reading papers, articles & PDFs. Clip highlights, chat with your research, and recall saved notes, all in one place.

The AI sidebar that lives inside your browser, right next to any paper, article, or PDF you open. It helps you save what matters, ask questions about what you've read, and actually remember your research over time. 🟢 Quickly explain articles as you open them Stop wasting time reading long texts that don't have anything relevant to you. Instantly get summaries about the whole passage. 🟢 Save anything as you read If you find something important that you don't want to lose, clip a highlight, a paragraph, or an entire article with one click. Everything you clip is stored and ready to come back to later. With AI memory, Constella auto organizes it so that nothing will be lost. 🟢 An AI that knows what you've saved Most AI tools start from scratch every time you open them. Constella remembers everything you've clipped and saved. Ask it a question and it pulls from your own research to answer, not just the open internet. Ask it to find a specific finding from something you read last month. Ask it to explain a concept from a paper you saved. Ask it to connect ideas across different articles you've collected. It works like a research assistant that has actually read everything you have. 🟢 Works on any page Open a journal article, a news story, a blog post, or a PDF and Constella is right there in the sidebar. No copying and pasting into another tab. No switching between apps. Your AI assistant is always one click away, on any page you visit. For curious people who read every day. You don't have to be an academic to get value from Constella. If you read the news every morning, Constella helps you save and make sense of what you read. If you follow newsletters, blogs, or long-form writing, Constella turns your reading into something you can actually build on. If you're someone who loves learning and wants to remember more of what you read, Constella is built for you. Researchers use it to connect findings across sources and ask questions across their whole library. Students use it to stay on top of papers and readings without losing their notes. Lifelong learners use it to build a personal knowledge base out of everything they find interesting. If you find yourself with dozens of open tabs, losing track of articles you meant to read, or forgetting what you learned last week, Constella is built for you.
