Perplexity Mobile 4

• 1. overview (466 chars)

  Perplexity’s mobile app is betting on voice search in 2026. The core of this round of updates, labeled "Mobile 4" by Product Express, is to upgrade the Voice Mode from "reading answers" to a natural conversation experience of "searching while asking, with source traceability", and is being rolled out on both iOS and Android. For ordinary users, the biggest somatosensory change is: holding down to speak is no longer like a walkie-talkie, the voice can be directly linked to real-time Internet search, and the answer still has the source of the reference.

• 2. Product background (857 chars)

  Perplexity AI was founded in 2022 by Aravind Srinivas and others. It is headquartered in San Francisco, USA, and the main company is Perplexity AI, Inc.. It first emerged as an "AI search engine with references". It released its first-generation search product on December 7, 2022, and subsequently launched iOS, Android Apps and Chrome extensions from 2023 to 2024. The mobile App (App Store application name "Perplexity - AI Search & Chat", iOS App ID 1668000334; Android package name ai.perplexity.app.android) currently covers 114 countries and regions around the world, and has been downloaded more than 80 million times on iOS. The App Store rating has remained at 4.8 for a long time (about 400,000 ratings). In September 2025, the company completed a US$200 million financing led by IVP and Wayra, with a valuation reaching US$20 billion; by 2026, its monthly active users across all products had exceeded 100 million, and its independent search products processed approximately 780 million queries per month.

• 3. Product functions and usage experience (1155 chars)

  The main line of this round of mobile updates is voice. The early voice function could only read the answers aloud, the interaction was similar to a "walkie-talkie", and the sound was mechanical. The new version adds six new voices to iOS and introduces a spherical dynamic dot matrix to replace the original microphone icon, making startup and interaction smoother. The voice mode is deeply connected with real-time search: when the user asks a question, the system performs automatic speech recognition (ASR) while calling the underlying large model (Claude 3.5 Sonnet, GPT-4o or Sonar Large, etc. depending on the subscription level), and then reads the generated results through neural text-to-speech (TTS), presenting real-time search results with links throughout the process. Both Android and iOS support hands-free continuous conversations, and the playback speed on the mobile terminal can be adjusted up to 2x speed. Compared with the web page, the app directly calls the system-level speech API (Android SpeechRecognizer, iOS SFSpeechRecognizer), with lower latency, and can be downgraded to a local lightweight model to complete the transcription if the network is weak. It can also be invoked through the lock screen and one-click activation of the control center to link with Siri. These are things that the web page cannot do due to browser permissions.

• 4. Pricing and business model (629 chars)

  Perplexity shut down its advertising business entirely in February 2026, with revenue coming entirely from subscriptions. The free file is not a decoration: unlimited basic searches, with web page visits and citation sources, plus 5 Pro search quotas per day, and no ads at all. The Pro file is priced at US$20 per month, unlocking in-depth research, multi-model comparison (Model Council), file analysis and priority search weighting; there is also a higher-level Enterprise Max file for enterprise users, including cutting-edge models, stronger generation and research capabilities. For most researchers, the free version is enough, and Pro's price/performance ratio is considered to be higher than competing products at the same price.

• 5. User reviews (698 chars)

  The mobile experience has a pretty good reputation among users. A large number of long reviews on the App Store mentioned that it "feels like having a conversation with someone" and "can remember the context of a few weeks ago." The naturalness of the voice and the speed of response are frequently praised. Third-party reviews (such as Robius News 2026 review) gave it a "recommendation" and believed that the mobile version is an AI interface "born for mobile phones", with one-handed operation, fast response, and smooth questioning. Some users also complained: the default male voice timbre is not as pleasant as Gemini, context is occasionally lost in long conversations, and some cross-platform customization options are inconsistent. Overall, the mobile version is one of Perplexity’s most satisfying portals right now.

• 6. Industry evaluation (665 chars)

  The media generally regards this voice upgrade as a key step for Perplexity to benchmark ChatGPT and Google Gemini voice capabilities. The comparison by The TechBriefs shows that ChatGPT’s advanced voice is most like a real person (with laughs and interruptions), Gemini comes second and is natural, and Perplexity’s tone is more neutral and more “tool-like”, but its integration of “answer + source” is the core of its differentiation. The industry consensus is that Perplexity is not trying to overwhelm its opponents in terms of "anthropomorphism", but rather to strengthen its strengths in "search and trusted sources." As the June 2026 update advances the mobile voice mode to both iOS and Android, it is evolving from a "question and answer engine" to a "portable research assistant."

• 7. Controversies and Risks (691 chars)

  Risks mainly focus on two aspects. One is the shortcomings of the voice mode: the context of long conversations is maintained, the recognition accuracy of professional terms and niche queries is still unstable, and the cross-platform customization capabilities are inconsistent. The second is privacy. Along with the voice and AI browser Comet (available on iPhone on March 18, 2026, with built-in voice mode, in-depth research and cross-device synchronization), Perplexity will collect browsing history for ad targeting, and there is no opt-out option in the app, which is a warning line for privacy-sensitive users. In addition, Perplexity has been subject to copyright and data grabbing lawsuits from the Yomiuri Shimbun, Reddit and other organizations since 2025, and the legal risks have not yet been cleared.

• 8. Applicable groups and usage suggestions (756 chars)

  This mobile app is most suitable for information consumers who use their mobile phones as their main source: those who use voice to quickly check, do light research, and organize information while commuting will obviously benefit; those who are used to "asking questions while reading web pages" can use the free Comet browser. It is not suitable for users who require strict privacy isolation or have high requirements for anthropomorphic speech - the former is recommended to be cautious in authorization, and the latter is currently superior to ChatGPT and Gemini in terms of naturalness of speech. As an alternative, if you are purely researching, you can choose the Perplexity web client, if you are pursuing anthropomorphic speech, you can choose ChatGPT Advanced Voice, and if you want system-level built-in, look at Browsing Assist, which is a collaboration between Samsung and Perplexity.

• 9. Summarize (307 chars)

  The essence of Perplexity Mobile 4 is to twist "voice + real-time search + trusted sources" into a convenient portable link. It does not win over the opponent in "human-likeness", but it has moved its strongest search strength into its pocket. For most people looking for answers on their mobile phones, it is one of the most worth-installing AI search portals in 2026.

  Searching for things is ten times easier than Baidu.

  I like the daily information flow of Discover. You can find out what’s new today by scrolling through it on your commute, which is easier than searching by yourself. However, the content is biased toward the English community, and there are not many Chinese topics.

  The little dot animation in the middle on the iOS side is quite cool. It will spread out and come together when you speak. It is much more energetic than the original microphone icon.

  Compared with ChatGPT, I use it as a search engine more often. The answer comes directly from the source without having to click ten blue links myself. "Pursuing questions" also goes smoothly. After asking one question, I ask another question, and the understanding keeps increasing. This is especially obvious when writing or doing homework. It can bring scattered ideas into a line, and I basically don’t have to open a bunch of tabs to put them together myself. The disadvantage is that ChatGPT is more stable for complex reasoning.

  It's so convenient to ask directly when cooking, without having to type with one hand and the other.

  Students think Pro’s $20 per month is a bit expensive. Isn’t there an “education discount”?

  The voices in the new version all sound like robots, not as good as the previous "Alex".

  The voice mode on Android is finally available, and it’s more comfortable to ask directly than to poke the screen while walking. It’s just that the bookmark history on the phone and computer haven’t been completely synchronized yet, so wait for this.

  Voice input sometimes stops suddenly and the screen goes black, which interrupts my train of thought.

  Let’s talk about a real-life scenario: Last week I helped a friend look at second-hand cars, and I took a few photos and threw them in. It helped me compare the listing prices and common problems on the three platforms, and it took me ten minutes to do what used to take an afternoon. The combination of photo search and voice questioning is particularly smooth on mobile phones, and it is much faster than reviewing reviews on Dianping. Especially for tasks where information is scattered and requires repeated comparison, it spreads out all the sources at once, saving me a lot of time switching apps back and forth.

  The free version is really useful. Five Pro searches per day are enough for daily verification, and the remaining basic searches are unlimited and come with cited sources. I basically cannot do without it when searching for information and doing homework. The only awkward thing is that the coverage of Chinese sources is still a bit lower than that of English. I occasionally overturn when searching for domestic information. You have to admit this. For things like checking abstracts of papers and comparing product parameters, it takes much less effort than traditional search engines. Even when you encounter particularly local information, you still have to verify it yourself.

  I tested about 80 voice questions on the iPhone 16 Pro. The recognition rate is indeed high in a quiet environment, and the source card is returned within two seconds. However, it drops to 70 to 80% when there is a noise around. During long conversations, I occasionally forget what I said earlier. While Siri's replacement is more than adequate, searching for information is still no match for Google.
