Hey Product Hunt! Solo dev here, and I'm a little nervous sharing this. A year ago I caught myself doing something absurd: ChatGPT in one tab, Claude in another, Gemini in a third, pasting the same question into all three and trying to figure out which answer was actually right. So I built an app that does it for me. OneAnswerAI sends your question to GPT-4o, Gemini and Claude at the same time and fuses the three replies into one answer — either picking the best or synthesizing them. But the thing I'm most proud of, and the reason I rebuilt half the app this year, is this: it now does a live web search BEFORE answering. Most AI apps (including my first version) just guess from old training data and hand you last year's facts with total confidence — wrong "latest iPhone", outdated prices, last season's news. OneAnswerAI now searches the web in real time, grounds the fused answer in what it actually finds, and shows you the sources. That alone killed most of the hallucinations. Three things I learned the hard way: - Fusion can't be summarization. A summary of three answers is worse than any single one — it had to identify what each model got right and resolve the contradictions. - Knowing when NOT to merge. For a factual/web question, one good grounded answer beats three averaged ones. - Every query costs me 3-4 API calls, which shaped the entire freemium model. It's free to try on iOS, no signup. I'd genuinely love your honest feedback — what works, what feels off, what's missing. Solo projects get better because of communities like this one.
