LEANSPEC
🤖Built with AI
From Idea to Action Instantly
Structure your AI chats into actionable project plans
— so you can stop organising and start building.
Why I Built This?
As an indie dev, I was tired of jumping between Notion, Jira, and a dozen other tools just to keep my product ideas organised. They were either too rigid, too bloated, or just not built for people like me who think in conversations, not tickets.
I built LeanSpec to solve a problem I face every day:
How do I turn fast, messy brainstorming into clean, structured plans without breaking my flow?
This is the tool I wanted for myself. If you think in ideas, not checklists, you might want it too.
