Daymon

Daymon is a free, open source desktop app that adds scheduling, persistent memory and background automation to Claude. It sits in the menu bar, connects to Claude Desktop or Claude Code, and runs tasks on a schedule even when the app is closed, so a user's existing Claude subscription keeps working overnight without API keys, cloud servers or an account. It is built for individual Claude users who want recurring work done while they are away, such as summarising an inbox every morning or checking news sources each weekday. Tasks are set up by talking to Claude in plain language rather than writing cron syntax. Persistent memory stores facts in a knowledge graph with semantic search so they carry across sessions. Workers are named agent personalities with their own system prompts that can be assigned to different tasks, with templates included. Auto nudge shows background results in the active Claude Code chat, configurable per task to always, failures only or never. Session continuity lets each run build on the previous one, and file watchers trigger tasks when files appear in a folder. Daymon configures Claude Desktop and Claude Code automatically on first launch. Daymon costs nothing. It uses the Claude subscription a user already pays for, and the source is on GitHub. Everything runs locally, with data kept in a SQLite file on the user's machine. The macOS build is available now, including through Homebrew, while Windows and Linux builds are marked as coming soon.
