Anthropic's AI assistant for real work, from chat to agents
Access to a range of Claude models tuned for different tradeoffs between speed, cost, and reasoning depth, including vision and long-context work.
Claude can produce working code, documents, slides, and spreadsheets in an editable side panel or output file rather than only plain chat replies.
Hand off multi-step tasks; Claude can search the web, read files, run code, and work across schedules or connectors depending on your plan.
Dedicated coding surfaces plus a developer platform and console for building applications on Claude models with API access.

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.
