Ask once
Type your question in the Qorpus compare dock on qorpus.ai or in the desktop browser extension. No copying prompts between tabs.
Compare AI answers side by side
One prompt goes to ChatGPT, Gemini, Claude, Perplexity, and Grok at once. Qorpus shows what each AI catches, where they disagree, and which details are worth keeping before you decide.

Why compare AI responses?
Not because one AI is useless. Because each AI is different. ChatGPT may structure the answer best. Claude may give the cleaner wording or code shape. Gemini may emphasize a different constraint. Perplexity may provide useful source trails. Grok may add a timely angle.
Side-by-side comparison breaks anchoring: you see consensus quickly, spot outliers that need a second look, and collect the strongest pieces from multiple answers instead of settling for the first polished draft.
How Qorpus compares AI answers
Compare every AI
Qorpus sends your prompt to major AI services using your existing desktop browser sessions — not a proxy API.

Compare results
Read answers together. Note shared facts, conflicting claims, and details only one AI mentioned.
Follow up smarter
Ask targeted follow-ups on the gaps you found. Comparison turns one vague answer into a verified decision.
Keep the best parts, verify the risky ones
Comparison is not only a hallucination check. It is a better decision workflow:
- Shared claims across ChatGPT, Gemini, Claude, Perplexity, and Grok are more likely to be reliable.
- Outlier claims from a single AI deserve extra scrutiny or a source check.
- Missing details — when only one AI mentions a risk, caveat, phrase, code pattern, or recommendation, that is often the most useful line.
Qorpus is built for this workflow: compare-first, desktop browser-local, and designed around judgment — not just sending prompts to many tabs.
Qorpus vs. a single chatbot
A chatbot gives you one perspective. Qorpus is a comparison layer for AI answers: you ask once, every major AI responds, and you compare for stronger judgment. Your data stays in your desktop browser. You use your existing AI accounts. No API keys required.

Frequently asked questions
Why compare AI answers instead of trusting one chatbot?
Each model has different strengths and failure modes. Side-by-side comparison reveals agreement, contradictions, and unique details you would miss with a single answer.
Which AIs does Qorpus compare?
Qorpus sends one prompt to ChatGPT, Gemini, Claude, Perplexity, and Grok using your existing desktop browser sessions.
Do I need API keys?
No. Qorpus uses your logged-in desktop browser sessions rather than a proxy API.

Complex prompts worth comparing
Qorpus is most useful when the ask has judgment, constraints, and room for disagreement: research, writing, coding, planning, and recommendations.
- I have $100,000 to invest over the next 10 years. Compare a global index fund, a dividend portfolio, and AI-related companies with expected returns, downside risks, taxes, and failure scenarios.
- Draft a patent-style invention disclosure for a wearable sensor system that monitors hydration and electrolyte balance during endurance exercise. Include novelty, claims-like groupings, prior-art risks, implementation details, and places where a patent lawyer should tighten the language.
- Debug a production memory leak in a Python FastAPI service using SQLAlchemy, async workers, and Redis queues. Give likely causes, instrumentation, fixes, and regression tests.
- Plan a 12-day multi-stop Japan trip for two adults and one parent with limited mobility, balancing transit, rest days, hotel locations, weather risks, and a $7,000 budget.
- Recommend a laptop under $1,400 for local AI experiments, software development, light video editing, and travel with MacBook, Windows, and used workstation trade-offs.
