GradeLab vs Conju

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.

Conju gives home service companies two SMS and voice assistants on one platform. The Receptionist texts back missed callers and answers calls 24/7, while Revenue Recovery follows up on unsigned estimates and dormant customer lists until a job is booked on your calendar.

Generic chatbots broadcast one script to everyone. Conju splits the workflow: one assistant catches new inquiries in real time, and the other mines quotes your office never had time to chase. Owners approve message templates first, messages send from their business number, and Recovery can charge per booked job instead of flat software fees alone.

The site targets roofing, tree care, and painting contractors who lose jobs to voicemail and quiet estimates. Receptionist plans start at $149 per month flat, with Recovery and Full Team tiers that add list-reactivation campaigns and automatic handoffs between the two assistants.
