Hey Product Hunt! I’ve always loved exploring software. Some of my favorite products include Heptabase, Dia Browser, Hermes Agent, and Cursor. Whenever I discover a feature that feels truly thoughtful, I still get excited and think: it’s amazing that we get to live in a time like this. When the Agentic AI wave started taking off, I wanted to join in and learn by building. I also remembered the “submersion learning” approach I experienced at school: jump in, get overwhelmed, and learn while doing 😌 That’s how Cometline came to life. Cometline started as a toy project — a BYOK AI chat app inspired by the parts I love from different tools, with a few personal ideas added on top. It supports: 1. Workspace-based context isolation 2. Discord integration 3. Spawning sub-agents through ACP 4. Coding delegation with claude code, opencode and codex 5. Long-term memory and reusable skills 6. A carefully crafted desktop UI/UX The frontend is built with Svelte and Electron, while the agent core and database layer are written in Go with SQLite. There’s still a lot to improve, but I recently realized that Cometline can now help me improve Cometline itself. That felt like a small but meaningful milestone. So today is the day I’m finally sharing it with everyone. 🎉 Thanks for checking it out!
