Why settle for one AI's answer when you can have five? OmniThink sends your question to ChatGPT, Gemini, Claude, DeepSeek and Grok at the same time and streams every answer side by side. No tab-switching, no copy-pasting, no wondering whether a different model would have said something better. Then it goes further than any single chatbot can: COMPARE — an instant analysis of where the models agree, where they contradict each other, and what each one missed. META-ANSWER — every distinct point from all five answers merged into one complete answer, with a coverage check proving nothing was dropped. VERDICT — an impartial judge picks the best answer, scores each model, and lists the factual disagreements you should know about before you rely on anything. DEBATE — the models argue it out over multiple rounds (standard, Oxford, courtroom, red-team and more), a blinded jury scores the rounds, and you get a 360° conclusion. You can even vote before the reveal. BUILT FOR REAL WORK • 46 answer modes and personas • Live web search with inline citations • Attach documents and images, or ask by voice • Long-form input • Follow up with one model or all • Copy anything with formatting intact • Save, share, revisit HONEST AND PRIVATE • Transparent metering: one answer = one model's reply — a usage meter shows where you stand all month. • Private mode: conversations are never stored and never linked to you. Start free — no credit card. One question deserves every frontier answer.
