Use Perplexity Sonar Pro inside MultipleChat to search the live web, get cited answers, and compare the result with the latest ChatGPT, Claude, Gemini, and Grok.
Search is powerful. But a source-backed answer still deserves a second opinion.
One question. Live sources. Multiple AI perspectives.
What changed in AI regulation this week?
Sonar Pro searches current sources before answering
New guidance, court decisions, and agency updates are summarized from current primary sources before the answer is written.
Each factual claim can be checked against citations, so your team can verify the source instead of trusting model memory.
MultipleChat can compare the same question across models and show where answers diverge.
Example sources
Most AI tools either guess from memory or give you a pile of links. Sonar Pro closes the freshness gap. MultipleChat adds the second layer: compare, challenge, and verify before you rely on the answer.
Fast-moving topics change faster than static training data can keep up.
If you cannot trace the answer, you still have to research everything manually.
Even sourced summaries can miss context, misread a page, or overstate a conclusion.
Sonar Pro finds the sources. MultipleChat helps verify the answer.
Live research plus model comparison is safer than trusting a single response.
Click the web search icon in the input area, ask once, and Sonar Pro retrieves current sources. Other models can reason over the same question. MultipleChat shows the answer, the sources, and the disagreements.
Click the web search icon
Use the web search icon in the input area to request fresh information for market, legal, technical, academic, and news questions.
Attach the citations
Trace important facts back to source links instead of relying on memory.
Compare the reasoning
Use the latest ChatGPT, Claude, Gemini, and Grok to challenge the conclusion.
Freshness is not the same thing as certainty.
The strongest workflow is current sources plus independent model perspectives.
Live search is only the first step. MultipleChat turns it into a repeatable research workflow.
Send a question once. Sonar Pro brings current sources. The latest ChatGPT, Claude, Gemini, and Grok add reasoning, comparison, and disagreement detection. You get a stronger answer than search or a single AI model can provide alone.
Sources show where facts came from. Disagreements show what to inspect.
Learn about AI collaboration →Ask about recent policy changes, product launches, funding rounds, docs, security updates, or market events without relying on outdated model memory.
Source-backed answers make review faster. You can inspect the underlying page when a claim matters.
Use a second model to challenge the response. Weak claims, contradictions, and missing context become easier to catch. Learn more →
Turn sourced research into reports, briefings, proposals, and summaries with MultipleChat document workflows.
Find current library versions, API docs, release notes, changelogs, and security advisories from live sources.
Keep sources, files, and follow-up questions organized by project so research does not vanish between chats. Learn more →
Find current pricing, launches, funding, hiring signals, and strategy changes with citations.
Track new rules, agency updates, and court decisions from live sources.
Find recent papers, methods, claims, and related publications without hallucinated references.
Summarize what changed today, then compare how other models interpret the impact.
If the answer can change, you need live sources. If the decision matters, you need verification. Sonar Pro and MultipleChat give you both in one workflow.
Model names change constantly. MultipleChat keeps the page stable by describing the model families and providers.
