AI agent that handles repeated tasks through reusable skills
Agent-Sin is a personal AI agent that handles the small daily chores quietly stealing your time — email, news, todos, "where did I put that?" searches across Slack and notes. Just ask in plain language. Agent-Sin turns your request into a reusable program (a "skill"), so the same task runs reliably, fast, and cheaply — every time. No prompt drift, no surprise bills.
Hey Product Hunt 👋
Maker here. I built Agent-Sin because I kept hearing about AI agents but couldn't find one that actually fit into my daily life.
The problem with prompt-based agents: same request, different result. Slow. And the bill keeps climbing.
So I took the opposite approach — let the agent write a small program for each task, and just run that program from then on. Stable, fast, cheap.
A few things you can ask it to do: • "Check Gmail every hour, surface only what needs a reply, archive the rest." • "Every morning at 9, send me today's todos and a news digest from my RSS feeds + NYT." • "Notify me when a Stripe sale comes in." • "Find that thing I mentioned last week — check Slack, Notion, and my notes."
It runs on Mac and Windows, supports local LLMs (free to run on a Mac mini or PC), and you can chat with it from Terminal, Discord, or Telegram.
Memory is stored as plain Markdown — you can open it, read it, edit it. No black box.
Would love to hear what you'd want your own agent to handle. Happy to answer anything 🙏
