“I’m posting this one more time because I’m still happy (and confirmed by many) that most humans can read it and understand it and all AI completely misunderstands. Perplexity AI, I am told, got it right but the rest think it’s sci-fi. It’s not. psychopete1.substack.com/p/krasnov-...”
“I was wondering how Perplexity is doing since I don't think I've heard of anyone using them for while, but it seems like this market is dragging even them along. I had a free year of Perplexity Pro but I used it maybe 5 times. adds nothing www.ft.com/content/e9c2...”
“NEW: A court ruled that Big Tech companies like Amazon can't use an anti-hacking law to go after users and developers of digital tools, like Perplexity AI, that people use to improve their online experience. This is the right call.”

Discussion around Perplexity over this four-week window was genuinely mixed, with the conversation pulled in competing directions by enthusiastic feature praise on one side and persistent quality and trust concerns on the other. Feature-related praise dominated the positive side of the conversation, with commenters frequently highlighting specific capabilities and reacting to new releases. AI quality also drew notable praise counts, suggesting a segment of users remained impressed by the product's core search and answer generation. That said, the same theme of AI quality ranked as the top complaint as well, pointing to a divided and vocal user base with sharply inconsistent experiences.
Sentiment drifted slightly downward through the middle weeks of the window, with scores declining from an already moderate starting point before a more notable lift arrived in the final stretch. The spike in both mentions and score in the last week of August stood out as the clearest directional shift in the period, suggesting a wave of more positive reaction, possibly tied to a release or announcement, though discussion did not clearly resolve around a single catalyst.
Privacy concerns and allegations around content sourcing generated a distinct thread of skepticism. Several mentions referenced ongoing legal disputes with media organizations, and commentary around potential AI influence operations added a sharper critical edge to discussion. These threads carried a tone of broader distrust rather than product-specific frustration, often folding Perplexity into wider skepticism about the AI industry.
Competitor comparisons appeared on both the praise and complaint sides roughly evenly, suggesting opinion was genuinely divided on where Perplexity stands relative to peers like ChatGPT and Claude. Some commenters positioned it favorably while others used competitor examples to highlight shortcomings. Hallucination complaints and bug reports, while lower in volume, added a layer of reliability concern that tempered some of the feature enthusiasm expressed elsewhere.
