Trellis

Trellis is an AI-powered reading and learning companion that helps users understand code, formulae, and complicated prose. It offers features like plain English explanations, language translation, and diagram generation. Trellis also provides AI-narrated audio versions of files and allows users to have conversations with an AI tutor named Celeste about their reading material.

Users can upload documents from their computer, Google Drive, or Dropbox. They can then read PDFs, ePUBs, and other text files on web, mobile, and tablet. Users can interact with the text by highlighting, annotating, and asking questions. They can also listen to audio versions of the files and share their reading logs and notes with friends.
