TangoEye vs HARPA AI

TangoEye is in-store retail analytics and automation software that turns existing CCTV cameras into footfall, zone, and conversion data. Instead of manual clickers or new sensor hardware, it plugs into the camera network retailers already run. The platform splits into four modules: Tango Traffic for walk-in counts, Tango Zone for shelf and area heatmaps, Tango RevOp for missed-sale tracking, and Tango StoreOps for camera and network uptime.

Most retail analytics vendors sell dedicated counting sensors or gate hardware. TangoEye's pitch is pure software on top of cameras that are already mounted, which keeps rollout cost lower and avoids ripping out existing infra. That trade-off means you need working CCTV coverage and bandwidth at each store, but you skip the cap-ex cycle of installing parallel sensor networks.

Retail operations teams use it to see bounced visitors, engaged shoppers versus casual walk-ins, and zone-level dwell time without standing at the door with a tally counter. Brand leaders at multi-store chains like Lenskart and Nykaa, listed on TangoEye's site, get a shared view of conversion leaks and infrastructure blind spots across locations. Store managers get hourly alerts when cameras or networks drop so footfall data does not silently go missing.

HARPA AI is a browser extension that puts GPT-5.4, Claude 4.6, Gemini 3.1, DeepSeek, and Perplexity on any web page you visit. Press Alt+A to summarize YouTube videos, draft Gmail replies, rewrite selected text, monitor pages for price drops, and run 100+ page-aware automations without copying content into a separate chat window.

Unlike standalone ChatGPT tabs, HARPA reads the page you are on, so summaries, email drafts, and data extraction stay grounded in the actual source. It also bundles web monitoring, SEO keyword research, Midjourney prompt builders, and Zapier or Make.com triggers in one sidebar, which general chatbots do not ship out of the box.

Marketers, researchers, recruiters, and developers use HARPA to speed up search, inbox triage, copywriting, and lightweight browser automation. The extension runs locally, does not log conversations by default, and supports local Llama models plus your own API keys if you want full control over data routing.
