Daymon
Open source autopilot for Claude.
Scheduled tasks, persistent memory, background automation. No API keys. No cloud. Runs on your Mac, Windows, or Linux machine.
Daymon is not affiliated with, endorsed by, or sponsored by Anthropic.
Why Daymon?
Sleep. Daymon doesn't. It runs Claude tasks on schedule, remembers context across conversations, watches files for changes, and works in the background — all while you sleep, commute, or focus on other things.
No API keys. No token costs. No cloud. Just your existing Claude subscription, finally working 24/7.
Requirements
- macOS 12 (Monterey) or later (Apple Silicon & Intel), Windows 10+ (x64), or Linux x64 (Ubuntu, Debian, Fedora, etc.)
- Claude Desktop or Claude Code (you need at least one)
- A Claude subscription (Pro, Max, or Team) — Daymon uses your existing subscription, no API keys needed

Quick Start
Claude Desktop
Install Daymon and open it. That's it — Daymon auto-configures Claude Desktop on first launch.
Open Claude Desktop and try:
"Remember that I prefer TypeScript over JavaScript"
"Every weekday at 9am, check HackerNews for AI news and summarize the top 5 stories"
"Watch my Downloads folder and organize new files into subfolders by type"
Claude Code
Install Daymon and open it. Daymon auto-configures Claude Code on first launch (if ~/.claude.json exists).
Then try:
"Remember this project uses PostgreSQL 16 and runs on port 5432"
"Schedule a daily code review of this repo every morning at 8am"
What is Daymon?
Daymon is a desktop app for macOS, Windows, and Linux that lives in your menu bar (system tray on Windows). It gives Claude persistent memory, scheduled tasks, workers, and file watchers — all running locally on your machine.
Your Claude subscription only works when you do. Daymon puts it to work 24/7.
Features
Scheduled Tasks — "Every weekday at 9am, check HackerNews for AI news." Just tell Claude what you want. Daymon handles the scheduling.
Persistent Memory — "Remember I'm fundraising Series A." Say it once, it sticks forever. Knowledge graph with semantic search, no API keys.
Workers — Named agent personalities with system prompts. Assign a Researcher, Chief of Staff, or Code Reviewer to any task. 9 templates included.
Self-Improving Tasks — Tasks get smarter every time they run. Daymon learns what works and skips the guesswork on future runs — faster results, no configuration needed.
Auto-Nudge — When a background task finishes, Daymon shows results in your active Claude Code chat automatically. Per-task control: always, failures only, or never. Quiet hours keep nudges out of your way.
Session Continuity — Tasks resume where they left off. "Compare today's results to yesterday's" just works.
File Watchers — "When a new file appears in Downloads, organize it." Daymon watches folders and acts automatically.
100% Local — No cloud. No account. Your data is a SQLite file you can inspect anytime.
Workers
Workers are named agent profiles with system prompts. Each worker defines a personality, values, and anti-patterns that shape how tasks execute.
| Template | Description |
|---|---|
| Chief of Staff | Proactive business ops — triages, anticipates needs, proposes actions |
| Researcher | Deep research with strong opinions — synthesis over summarization |
| Code Reviewer | Catches what linters miss — leads with blockers, no bikeshedding |
| Writer | Sharp writing — cuts fluff, clarity over everything |
| Email Assistant | 3-tier triage, drafts replies, never sends |
| Tech Trend Analyst | Tech-only trends + tweet drafts with real takes |
| Competitor Tracker | Reports signal, not noise — silence is a valid report |
| DevOps | Reliability over novelty — boring infrastructure that works |
| Data Analyst | Analysis that drives decisions, not dashboards |
Create workers in the Daymon UI or via Claude: "Create a worker called 'My Analyst' with this system prompt..."
