Ask every AI at once. Get one answer.
One question goes to up to 6 AIs at once: ChatGPT, Claude, Gemini, DeepSeek, Grok and a Wildcard seat from OpenRouter. They answer side by side, then challenge each other’s reasoning, and a synthesis builds one answer from the strongest points, showing where they disagreed. Bring your own API keys and pay each provider directly, no markup. Try the free preview first: 3 questions a day, no account.

WildcardCold plunges and ice baths: real recovery benefit or placebo?
ChatGPTGPT-6 LunaShort answer: not just placebo—but the benefit is mostly “I feel less sore,” not “my muscles have healed faster.” Soreness and perceived recovery: Cold-water immersion can reduce post-workout soreness and make people feel more recovered for a day or two.
GeminiGemini 3.8 FlashThe short answer is it is a mix of both real physiological mechanisms and a substantial placebo effect—and whether that physiological effect is actually a benefit depends entirely on what you are training for. Cold water immersion (CWI) is not a magic cure-all, nor is it purely snake oil.
GrokGrok 4.3Cold plunges and ice baths (cold-water immersion or CWI) provide some real recovery benefits beyond pure placebo, particularly for reducing perceived muscle soreness (DOMS) and certain biochemical markers of muscle damage, but effects on performance recovery are modest, context-specific, time-dependent, and partly…
ChatGPTPeer review I’d keep my original bottom line, but make one distinction sharper: cold-water immersion can help on average versus passive rest, especially with soreness, but it’s less clear how much of…
GeminiCritique of Peer Responses ChatGPT (gpt-6-luna): Strengths: Excellent conciseness. Importantly, it introduced a critical safety disclaimer (cardiovascular stress and cold-shock response) that my…
GrokI am maintaining my original position with no revisions. My initial answer already provides a more comprehensive, evidence-based synthesis grounded in multiple systematic reviews and meta-analyses (e.
Issues Found The "wait 4–6 hours after lifting" figure was presented as an established threshold. It's a reasonable practical heuristic, but no cited review quantifies it; treat it as a rule of thumb, not a data-derived cutoff. Lower creatine kinase (CK) after cold immersion was treated by one response as evidence of less muscle damage.
Questions people ask
Is PolyCog free?
The preview is free with no account: 3 questions a day on 3 of the seats (Claude Haiku 5.5, Gemini 2.5 Flash-Lite, DeepSeek V4.1 Flash), 1 debate round and one synthesis. A free account runs on your own API keys with no daily cap, 4 seats at once and 20 saved chats. Pro is $10 a month or $250 once: 500 saved chats, all 6 seats at once, unlimited rounds. See pricing.
What does "bring your own key" mean?
You get an API key from each provider (there are step-by-step guides), paste it in once, and pay that provider directly at its list price. PolyCog adds no markup; a typical debate costs a few cents. Keys are encrypted (AES-256) when saved and used only for your own requests.
Which AIs are in it?
ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), DeepSeek, Grok (xAI), and a Wildcard seat that opens Qwen, Kimi, GLM, Mistral, Meta's Llama and Muse, MiniMax, Venice and Nous through one OpenRouter key. Which model is best for what profiles each one.
What does a debate do?
After the first answers, each model reads the others' and writes a rebuttal: what is wrong, what is missing, what it would change. Rounds continue until you ask for the synthesis, which combines the strongest points into one answer and shows where the panel disagreed.
