Sinth is an Android app that sends your prompt to five AI models simultaneously — Claude, ChatGPT, Gemini, DeepSeek, and Grok — and uses an AI fusion layer to produce a single consolidated answer. You also see each model's raw response side by side, which is useful for spotting disagreements, comparing reasoning styles, or just picking the answer you trust most. There's no subscription and no proprietary backend: you connect your own API keys, so you pay provider rates directly with no markup. Available as an APK for Android. Free to try.
