Thought Spark
Voice-capture ideas, then AI turns them into action
Most good ideas die in a notes app. Thought Spark treats capture as step 1 of 4: capture by voice in seconds (hands-free via Siri), let AI title and file it, sharpen it with a short AI interview tuned to how you think, research it on the web with real sources, and turn it into Apple Reminders and Calendar blocks. Ideas stay on your device. Free to capture forever; Pro unlocks unlimited refining and deep research.
Hi Product Hunt! I built Thought Spark because I kept losing my best ideas between the shower and the towel. Every capture app I tried was a graveyard: great at collecting, terrible at making anything happen. So the loop is the product: Capture, Clarify, Research, Act. You talk for ten seconds; it transcribes, cleans up the rambling, and titles it. When you have five minutes, an AI interview tuned to how you think sharpens it. When you are serious, it researches prior art on the web with real sources. And Act writes straight into Apple Reminders and Calendar, so the output lives where your day already happens. Honest notes: iOS only for now; ideas stay on device; capture is free forever, and Pro covers the AI costs for unlimited refine and web research. I would love brutal feedback, especially on where the loop breaks for you.
