Every creator knows the feeling: a promising idea clouded by doubt, assumptions, and endless “what ifs.” Spark is your AI thought partner, guiding you from concept to clarity. It's not another prompt-writing tool; it's a dedicated collaborator designed to give you clarity and conviction, with two powerful modes. Brainstorm Mode: helps you explore ideas from multiple angles, acting as a creative visionary or practical builder to uncover features and business models you might miss. Debate Mode: invites AI personas like a Devil’s Advocate or Skeptical Customer to challenge your assumptions and expose risks. The result? Clarity and conviction. Spot fatal flaws early, build confidence, and know you're on the right path. Spark also generates business plans, names, personas, and risk analysis instantly so you can go from spark to startup faster.
