IdeaStew

Most brainstorming tools ask you to explain what you want. That's the part you can't do yet — if you could describe the idea clearly, you wouldn't need help finishing it. IdeaStew works the other way round. You type the half-formed version, and it deals single words, one at a time, from deliberately not-obvious directions. You react on instinct: keep what fits, spark what pulls at you without you knowing why, drop the rest. It takes about a second per word. Sparks are the important verb — the next round of words chases them, and every round says which spark it's following. Reacting turns out to be far easier than articulating, and the idea assembles itself out of what you reacted to. When a session lands somewhere, IdeaStew writes it up. You get a sharpened, self-contained prompt to take into any AI — or, for a finished document, an emailed PDF: the developed concept, a pressure test that argues with your idea, a 30-day plan, one analogy that reframes it, a to-do list whose first step takes under an hour, and the trail of words that got you there. If what you're stuck on is a name, it switches into a name hunt: candidate names one at a time, "warmer" instead of spark, a steering line you can edit mid-hunt ("shorter", "darker", "no portmanteaus"), and a live check against the .com registry on every card, so you never fall for a name that was gone before you started. Free, no signup, works in your language.
