Welcome to QiMen AI β€” The pioneering platform where ancient Eastern Philosophy meets advanced Data Science and Artificial Intelligence. Designed for cultural researchers, environmental analysts, and students of traditional QiMen Dun Jia, QiMen AI proudly ushers in a new era: Applying Data Science to analyze, evaluate, and visualize QiMen matrices. By digitizing complex spatial data points, we transform the historical theories of QiMen Dun Jia into coherent, scientific, and highly accessible knowledge. CORE FEATURES: Real-Time QiMen Astrolabe Automatically establish and analyze traditional QiMen Dun Jia charts based on precise Astronomical Ephemeris and satellite positioning (GPS). The system calculates celestial mechanics and solar trajectories with absolute millisecond precision, ensuring all QiMen variables and historical algorithms are accurately reflected at your exact location and time. Data Science & QiMen Visualization Experience the world’s first platform to apply Data Science to dissect historical QiMen matrices. Traditional QiMen arrays are transformed into intuitive metrics, charts, and graphs. With our Professional PDF Reporting engine, you can effortlessly export your deep structural analyses into beautifully formatted, multi-page academic documents to save, print, and share. Exclusive AI QiMen Assistant Explore an in-depth library of over 300 curated lessons covering traditional QiMen philosophy, spatial geometry, and historical texts. Interact directly with our intelligent AI Tutorβ€”your personal advisor ready to accompany you, reason with you, and provide instant academic interpretations throughout your learning journey. Complete Astronomical Ephemeris A high-precision perpetual calendar tool for tracing traditional dates, Heavenly Stems, Earthly Branches, and real-time QiMen variables with absolute mathematical accuracy for historical and academic cross-referencing. AI Spatial Analysis & 3D Diagnostics β€’ 2D Blueprint Diagnostics: Upload existing floor plans for an automated AI audit. Evaluate architectural layouts against traditional structural guidelines to identify optimal spatial zones. β€’ Generative AI & Redesign: Automatically generate functional floor plans or restyle your interior using powerful Gen-AI to optimize visual layouts and spatial balance. β€’ 3D LiDAR Scanner: Transform your physical environment into an accurate digital twin and instantly capture room dimensions using your device’s LiDAR sensor.

About

Solvr

Features
Read full description

Solvr is your verified academic reasoning workspace for technical subjects. Built for students who want to understand exactly where they stand, not just get an answer. WHY SOLVR IS DIFFERENT Most AI tools will hand you an answer. Solvr shows its work and checks it. Every numerical solution is independently verified using a real symbolic computation engine (SymPy), running in a sandboxed environment, so you get correct, trustworthy answers instead of confident-sounding guesses. If an answer doesn't check out, Solvr automatically tries again with deeper reasoning before showing it to you. MISTAKE DETECTIVE β€” SEE EXACTLY WHERE YOU WENT WRONG Snap a photo of your own work next to the problem, and Solvr solves it independently, then compares your steps against the correct solution step by step. If you made an error, Solvr pinpoints the exact line where your reasoning diverged and explains the underlying misconception, so you actually learn from it. And if your work is correct? Solvr tells you that too. No invented errors, no false alarms. HOW IT WORKS β€’ Snap a photo of any problem (handwritten, printed, or a full worksheet) or upload a PDF directly β€’ Get a clean, step-by-step solution with properly typeset math; every problem on a worksheet is solved in one pass, not one at a time β€’ Ask Solvr follow-up questions about any step, right in the chat β€’ Use Mistake Detective to check your own attempt against the correct solution β€’ Track your Weakness Graph (the concepts that trip you up most) and get targeted practice problems to fix them β€’ Export any solution as a clean PDF or Markdown study sheet BUILT FOR STEM Solvr handles everything from basic algebra to multi-step calculus, physics mechanics, and chemistry stoichiometry with full LaTeX-rendered equations. PLANS β€’ Free: 3 verified solves a day, math only, perfect for trying it out β€’ Solvr Pro: unlimited solves across all STEM subjects, Mistake Detective, Weakness Graph, follow-up chat, and clean exports Solvr is a study tool designed to build understanding, not shortcut it. Every feature is built around one question: does this help you actually get better? Terms of Service: https://getsolvr.app/terms Privacy Policy: https://getsolvr.app/privacy
