Perplexity
AI SearchAI search engine with cited sources and synthesis
Overview
Perplexity represents the new generation of AI-powered search engines that synthesize information from across the web into comprehensive, cited responses. Founded in 2022 by former OpenAI and Meta researchers, it's gained significant traction as users increasingly prefer AI-generated summaries over traditional search result lists. For SEO practitioners, Perplexity matters because it's changing how people discover and consume content online.
Unlike ChatGPT or Claude, which rely on training data with knowledge cutoffs, Perplexity searches the live web and provides citations to source material. This makes it particularly valuable for current events, trending topics, and situations where you need to verify information. The platform has grown rapidly, reportedly handling over 500 million queries monthly as of late 2024.
What sets Perplexity apart from Google AI Overviews is its conversational interface and ability to maintain context across follow-up questions. While Google still shows traditional search results alongside AI summaries, Perplexity positions itself as a complete replacement for traditional search in many scenarios.

Common complaints
- –Billing and cancellation nightmares -- multiple users report charges continuing after cancellation, double billing on Max plans, and near-zero customer support response
- –Silently routed Pro subscriber queries to cheaper, less powerful models while displaying the user-selected model name; CEO acknowledged this as an 'engineering bug' in November 2025
- –Long conversation threads break down -- system asks Pro users to 'upgrade' or 'start a new thread' mid-conversation, and has no cross-session memory
- –Hallucination on niche topics remains a problem: only 26.5% of AI-generated bibliographic references were fully correct in systematic review, and citations sometimes link to homepages rather than exact source pages
- –Major copyright lawsuits from NYT, News Corp, Reddit, and Encyclopedia Britannica (40+ cases in US courts) raise questions about long-term content sourcing sustainability

“For strict research or fact-checking, Perplexity is the clear winner. But the moment I need creative writing or context-rich dialogue, I switch back to ChatGPT without hesitation.”

“Found out Perplexity was silently routing my Pro queries to cheaper models while showing Claude 3.5 in the UI. Paid $17/mo for months thinking I was getting premium inference. CEO called it an 'engineering bug' but the trust damage is done.”

“The NYT lawsuit against Perplexity is the canary in the coal mine. If answer engines can't figure out fair compensation for publishers, this whole model collapses. Great product, unsustainable business.”
