Free AI flashcard and study tools for students
Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.
Local-first desktop workspace where a doc editor and your AI coding agent share the same files
A familiar document editor sits alongside an AI agent that reads and writes the same files, so drafts, edits and research stay in a single place.
Sofos does not sell AI. It runs Claude Code or Codex against your local folder using your own subscription, and you can switch between them from the chat footer.
Documents are ordinary Markdown files in a folder on your Mac, compatible with Git, Obsidian and VS Code, with no proprietary format or lock-in.
Downloadable skill files teach the agent repeatable, role-specific jobs such as PRD-to-Jira epics, launch announcement kits and QBR deck builders.
