Sofos

Sofos is a desktop workspace for business teams that combines a Notion-style document editor with a built-in Claude AI agent. It runs entirely on your Mac, reading and editing your local markdown files directly. The interface is split into two panels: a familiar editor on the left and a real-time Claude chat on the right. You can ask the agent to draft content, update existing documents, pull data from connected apps, or summarize information — all without leaving your workspace. The tool is local-first, meaning your files stay on your machine as plain markdown, so there's no proprietary format or vendor lock-in.

The editor supports WYSIWYG markdown, callout cards, highlights, and even CSV editing with spreadsheet-like range selection. Sofos connects to over 17 integrations including Notion, Linear, Slack, Jira, GitHub, and Figma through the Model Context Protocol (MCP). Unique features include a Plan mode that shows every change the agent wants to make before applying it, and a skills library (Sofos Academy) where you can download pre-built instructions for tasks like turning PRDs into Jira epics or building launch kits. The agent can also handle file-by-file review and approval through GitHub, so non-technical team members can collaborate without needing to understand pull requests.

Sofos is ideal for product managers, founders, marketing teams, and anyone who lives in documents. It's designed for drafting PRDs, strategy memos, content calendars, investor updates, and playbooks. The combination of a familiar editor with an AI agent that works on your actual files makes it a practical tool for teams that want the power of AI without the complexity of a new workflow or the risk of data leaving their machine.
