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.

  • 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.

TemplateDescription
Chief of StaffProactive business ops — triages, anticipates needs, proposes actions
ResearcherDeep research with strong opinions — synthesis over summarization
Code ReviewerCatches what linters miss — leads with blockers, no bikeshedding
WriterSharp writing — cuts fluff, clarity over everything
Email Assistant3-tier triage, drafts replies, never sends
Tech Trend AnalystTech-only trends + tweet drafts with real takes
Competitor TrackerReports signal, not noise — silence is a valid report
DevOpsReliability over novelty — boring infrastructure that works
Data AnalystAnalysis that drives decisions, not dashboards

Create workers in the Daymon UI or via Claude: "Create a worker called 'My Analyst' with this system prompt..."
