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.

Share and access study materials worldwide — with AI study tools built in
Search a vast, student-contributed library of lecture notes, summaries, study guides and past exams organised by course and institution.
Generate notes, summaries and revision material from documents so you can study the essentials instead of re-reading everything.
Turn study material into interactive quizzes and flashcards so you can test yourself and target weak spots.
Use built-in text-to-speech to listen to study documents on the go, useful for revision during commutes or downtime.
