Every good idea starts as a spark — and most of them vanish before you do anything with them. Thought Spark catches them the instant they strike. Capture in seconds. Tap once and talk, or type. Thought Spark transcribes and titles your idea automatically. Sharpen it. A short, AI-guided interview asks the right questions to turn a vague notion into something clear — tuned to how you think (founder, writer, researcher, designer, PM). Research it. Send your idea to the web: Thought Spark scans for prior art, key context, risks, and directions worth exploring, with sources. Act on it. Turn an idea into reminders, a calendar work-block, and concrete next steps — so it actually moves. Your ideas stay on your device. Capture and basic features are free; Pro unlocks unlimited refining and deep web research. Start with a 7-day free trial of Pro — unlimited refining and deep web research.
