Sunday

Sunday is a personal agent and second brain that lives on your Mac and gets real work done instead of only talking about it. Core capabilities: • Remembers everything you tell it in plain markdown files you own • Reads your documents and email and drafts replies • Drives a browser using your saved logins • Fills out job applications and forms • Hands builds to Claude Code and Codex • Generates real PDFs and slide decks. Sunday acts on your browser, files, terminal and email, but it asks before anything goes out, so you stay in control of what gets sent. Its memory lives in plain markdown, which means your notes, plans and history remain portable and readable without locking you into a proprietary database. It also ships with six built-in apps and is free and open source under the MIT license. Designed for professionals, founders, job seekers and developers who want a private assistant that remembers context across weeks and projects. Use it for drafting correspondence, managing applications, researching decisions, building deliverables and coordinating work across your everyday tools.
