GradeLab vs TangoEye

GradeLab is an assessment platform built for schools, universities, coaching centers, and government exam bodies that need to grade handwritten and digital exams faster without giving up teacher control. Upload scanned answer sheets or run online tests, and the system applies your rubrics to score essays, math, diagrams, and mixed-format papers while flagging anything that needs a human review.

What sets it apart is the focus on real exam workflows: OCR trained on student handwriting across 30+ languages, on-screen marking for distributed examiners, question generation from PDFs, LaTeX exam paper formatting, and REST APIs for LMS and EdTech integrations. Institutions can deploy on-premise so exam data stays inside their network.

GradeLab targets K-12 schools, higher-ed departments, test-prep centers, corporate training teams, and public-sector assessment programs that process large paper volumes and want consistent grading with analytics parents and administrators can actually read.

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.
