What does Trellis do?
Trellis is an AI-powered reading platform that transforms how people interact with documents. You can upload PDFs, ePUBs, and other text files from your computer, Google Drive, or Dropbox, and the platform creates a centralized library of your reading materials. The core feature is Celeste, an AI companion that can discuss your reading materials with you, answering questions and providing insights about whatever you're studying.
What makes Trellis stand out is its dual approach to digital reading. It offers state-of-the-art text-to-speech conversion that creates audio versions of your documents, with customizable options to remove footnotes and marginalia for a cleaner listening experience. The platform also enables collaborative learning by letting you share reading logs and notes with friends, making it easier to study together. The mobile app (currently in beta) provides voice-first interactions for hands-free learning.
Trellis is particularly valuable for students who need help understanding complex textbooks, teachers who want to create more engaging learning experiences, and anyone who prefers audio content over traditional reading. The testimonials from educators highlight how it supports student-led learning and provides individualized attention through its always-available AI tutor, making it useful for both classroom settings and self-directed study.
