Agent-Sin - Build your own AI agent, one conversation at a time

Agent-Sin is a customizable personal AI agent that combines memory, daily logs, tasks, schedules, and programmable skills. Instead of starting from a blank chat every time, it learns your context over time and helps you move from conversation to action. Use it for daily briefings, task management, personal knowledge, product planning, content ideas, and custom automations. Developers can create custom skills to connect Agent-Sin with their tools and workflows.

Hey Product Hunt! I’m Shingo, an indie developer from Japan. I built Agent-Sin because I wanted an AI assistant that felt less like a disposable chat window and more like a long-term teammate. Most AI tools are great at answering one-off questions, but they forget your context, your projects, your preferences, and the workflows you repeat every day. Agent-Sin is my attempt to fix that. It combines conversation, memory, tasks, schedules, daily logs, and programmable skills. You can start with simple chat, then gradually teach it your own workflows by adding skills. I’ve been using it myself to manage product ideas, plan development tasks, review progress, prepare content, and connect with my AI coding workflow. Would love to hear what kind of personal AI workflows you’d want to automate with it.
