Perplexity vs Google AI Mode
Perplexity is a dedicated research product. Google AI Mode is AI search bolted onto the most complete web index in the world, free with a Google account. The trade-off is real — Perplexity has the better workflow and citation UX, but Google has the index, the integrations, and the price.
Perplexity wins for focused research and citation transparency. Google AI Mode wins for breadth, free access, and Workspace integration.

Key differences
Citation transparency
Perplexity puts numbered citations inline in every paragraph by default. Google AI Mode shows source links but the visual hierarchy buries them under the AI summary. For research where you need to verify every claim, Perplexity is significantly easier to audit.
Research workflow
Perplexity has Spaces (saved-source research), Pages (publishable write-ups), and Comet (a browser that knows what you are researching). Google AI Mode is a single-shot answer in a search results page. For accumulating research, Perplexity is in a different category.
Index depth
Google has the deepest, freshest web index that exists. Perplexity uses its own crawl plus partner data and is good but not Google-good on long-tail queries. For obscure or hyper-local searches, Google still wins.
Free tier
Google AI Mode is free with a Google account, no daily caps. Perplexity free caps Pro Search at 5/day. If price is the deciding factor, Google is hard to beat.
Multimodal results
Google natively blends images, video, Maps, shopping, and the knowledge graph into AI answers. Perplexity has images and limited video but the experience is text-first. For "show me photos of X" or "directions to Y," Google.
Workspace integration
Gemini (which powers AI Mode) integrates with Gmail, Docs, Drive, and Calendar. Perplexity lives outside that ecosystem. For knowledge work inside Google Workspace, Gemini is closer to your data.

Pick by use case
Academic research with citations
Academic focus mode and inline citations make verification easy. Google AI Mode answers are harder to audit.
Quick-answer factual lookup
Free, fast, and the index is unmatched. For "when did X happen" or "what is Y," Google is still the right reflex.
Multi-step research project
Spaces and Pages exist for exactly this. Google AI Mode has no equivalent of a persistent research workspace.
Research over a saved set of sources/PDFs
Spaces let you upload PDFs and add URLs as a research corpus. Google AI Mode does not have this.
Real-time news synthesis
Better at synthesizing across multiple recent sources with clear citations. Google AI Mode tends to summarize one or two articles.
Local search (restaurants, directions, hours)
Maps integration and local data are unique to Google. Not what Perplexity is for.
Privacy-conscious search
Less ad-driven data collection than Google. Not as private as You.com but cleaner than Google.
