Spark: Type what you're thinking
Type a thought, even a half-baked one. You get a burst of ideas around it: some close to what you meant, some from way out of left field. Click any of them to keep digging.
Costs 1 credit.
Ideaful: an intuitive AI ideation and brainstorming tool
Ideaful is an interactive ideation tool that helps you form new ideas and stress-test them, intuitively. Type a thought and watch it branch into a map of ideas: close ones that build on it, far ones from other fields. Merge ideas, hear the critics, research what already exists, and turn the best one into a one-page brief.
Try it free. Your first spark needs no account and no card.
How it works
From a single thought to your next project.
Merge: Bring ideas together
Got two ideas that don't obviously go together? Press Merge, pick the second one, and they turn into one new idea you probably wouldn't have landed on yourself.
Costs 1 credit.
Review: Tackle criticism early
Before you fall for an idea, let a few tough critics at it: an investor, a first customer, someone who knows the field. Each says what bugs them, and you see which problem could actually sink it.
Costs 2 credits.
Brief: Turn an idea into a full brief instantly
When an idea feels right, get it on one page: the problem it solves, who it's for, how it works, and a cheap first test you can run this week.
Costs 3 credits.
Deep Spark: Think it through first
Slower. It thinks first, then reaches further out.
Costs 4 credits.
Research: See who's already doing it
Checks the web for who's already doing it, and how that went.
Costs 6 credits.
It can learn how you think
Point Ideaful at your Obsidian vault. It picks up the themes you keep returning to, the notes your thinking hangs on, and what you've already written about the thought in front of you. Then it builds on your ideas instead of generic ones. Your vault is read in your browser and never uploaded, never written to, and only a short summary and a few matching excerpts travel with a spark.
