Perplexity evolved from search-with-citations into a full research platform. Deep Research runs multi-step investigations that take 2–5 minutes and produce comprehensive reports with sources — replacing hours of manual research. Perplexity Pages creates shareable, structured research documents anyone can read. Pro Search includes access to Claude, GPT-4o, and Sonar models for different task types. Shopping mode surfaces product comparisons with price tracking. The answer engine that replaced Google Search for research-heavy workflows.

RuView is a WiFi DensePose system that converts commodity WiFi signals into real-time human pose estimation (17 COCO keypoints), vital sign monitoring (breathing and heart rate), and presence detection — all without cameras, wearables, or any line-of-sight requirement. It runs on $9 ESP32-S3 edge hardware, making privacy-preserving human sensing accessible at near-zero hardware cost. The system uses spiking neural networks (SNNs) that adapt to new rooms in under 30 seconds via online STDP learning — no new training data required when you change environments. It achieves 92.9% PCK@20 accuracy with just 5 minutes of synchronized training data and exploits neighbors' WiFi routers as free radar illuminators via multipath modeling. The full stack runs on a $9 microcontroller with a companion Python processing server for the heavier inference. Applications span eldercare monitoring without privacy-invasive cameras, smart home occupancy detection, clinical vital sign monitoring, and security systems that work through walls. The privacy angle is genuinely compelling — you get full presence and activity awareness without any video data being captured or stored. Released April 22, 2026.
Reviewer scorecard
“Deep Research is legitimately impressive for technical evaluation — comparing libraries, auditing security postures, understanding architecture decisions. What used to take 2 hours of reading docs and Stack Overflow now takes 5 minutes and comes with citations I can verify.”
“The $9 hardware cost is the headline — prior WiFi sensing research required expensive SDR hardware or proprietary routers. ESP32-S3 + online STDP learning that adapts to new rooms in 30 seconds is a practically deployable combination. For smart home, eldercare, or building automation use cases this opens a category that was previously research-only.”
“Citations remain the core differentiator vs ChatGPT. Every claim is sourced and you can click through. Hallucination risk drops dramatically when the model knows it has to cite. Deep Research is good but sometimes slow — it works best when you have a few minutes, not seconds.”
“WiFi sensing accuracy degrades significantly in multi-person environments and with thick concrete walls — the 92.9% PCK@20 figure is likely single-occupant in a controlled lab setting. Interference from neighboring WiFi networks, Bluetooth, and microwave ovens creates real-world noise floors not represented in benchmarks. Treat this as a research demo until independent real-world replication confirms the accuracy claims.”
“Perplexity Pages is the underrated bet — turning AI research into shareable documents is how knowledge workers will collaborate in the future. The roadmap (Deep Research, Pages, shopping, Pro with multiple models) is building the AI-native knowledge platform, not just a better search engine.”
“Camera-free sensing resolves the fundamental tension between ambient intelligence and privacy. If WiFi-based pose and vital signs reach camera-comparable accuracy, the entire smart building and healthcare monitoring market re-orients around passive RF sensing rather than video. At $9 per node, this could be the hardware substrate for genuinely ubiquitous ambient AI.”
“The privacy-by-design framing is what makes this compelling beyond the technical novelty. Interactive installations, immersive environments, and wellness spaces that respond to occupant presence and movement without surveillance cameras are suddenly buildable by small teams. The creative applications for responsive environments are wide open.”
