They respond to attention. They fade without it. They connect to each other in ways you don't expect. They transform under sustained heat.
We built an AI-native idea catcher that knows this.
The reduction
You've been here before.
An idea arrives — mid-conversation, mid-walk, mid-sentence. It's alive. Connected to three other things you've been thinking about. You can feel it clicking into place.
So you capture it. You open the app. You write it down. You pick a folder, choose a tag, maybe link it to a project. And somewhere between the moment it arrived and the moment you pressed save — it stopped being an idea and became an entry. A bullet point. A card in a column.
The thing you captured isn't the thing you felt. It's a receipt for it.
And the worst part? You did everything right. You captured it, tagged it, filed it. And it will sit there — perfectly organized, perfectly still, perfectly silent — until you forget it exists.
Which you will, because nothing in that system knows the difference between an idea on fire and one that went cold six months ago.
You don't need a better filing system.
You need to stop filing.
The lifecycle
No categories. No folders. No tags you'll maintain for a week and abandon. Just the natural lifecycle of your ideas — visible, honest, alive.
Your attention is the fuel. Everything else is entropy. And for the first time, you can see it — not in timestamps and folders, but in the living shape of where your mind actually went.
No guilt. No streaks. Just an honest map of your active thinking.
How it works
Ideas arrive in the moments you can't engineer — mid-conversation with Claude, in the flash between one thought and the next.
You say “spark this.” That's it.
Claude captures the insight, names it, finds the connections to your other sparks, and places it in your graph. No context switch. No app. No friction between the thinking and the keeping.
Your ideas form a network — not a list, not a hierarchy, but a graph of connections that reveals clusters you didn't plan and patterns you didn't see coming.
And it breathes. Ideas you're working on glow. Ideas you've neglected fade. Ideas you've finished crystallize. Ideas that went out rest quietly at the edges, never deleted, always recoverable.
At a glance, you know where your thinking is. Not where you filed it. Where it lives.
Idea Lifecycle Management — Positioning Pivot
A real conversation. The moment Spark's positioning was born — captured without leaving the thought.
Integration
Spark uses MCP — Model Context Protocol — the open standard that lets tools plug directly into Claude. Think of it like an extension for your AI conversation.
Setup takes about five minutes. Works on Claude Desktop and Claude.ai, including mobile. Once connected, Claude can capture sparks, find connections, and manage your graph — all inside your conversation.
Your ideas are stored securely and never used for training. Export everything anytime. No lock-in.
Free during beta.
Pro at $8/month when we launch — unlimited sparks, custom timers, semantic search, analytics, and export. The free tier stays generous forever.
Join the beta
Spark is built for people who think inside AI.
Not people who use AI for quick answers. People who reason with it. Who arrive at ideas mid-conversation they didn't expect to have. Who've felt the particular frustration of losing something valuable to a closed chat window.
We're opening Spark to a small group. Free. No credit card. Just your Claude conversation and five minutes.
If this is how your mind works — you'll feel it on the first spark.
