Workstations are grouped into functional suites: AI Writing & Neural Analysis (powered by M33 latent vaults), Math & Academic Calculators (deterministic solvers), Document & Data Workstations (in-memory file converters), and Career & Recruiting Workstations. ### Which ZeeML tools run 100% offline inside the browser after page load? Our academic calculators, lexical analyzers, PDF document processors, and JSON/CSV data flatteners execute entirely inside your browser using client-side JavaScript and WebAssembly. ### How do I switch modes inside a ZeeML workstation? Use the segmented mode pills at the top of any workstation toolbar to switch registers (Fluency, Academic, Executive), grading scales (CBSE 9.5x, VTU, Mumbai University, US 4.0 GPA), or export formats in real time. ### Can I cite or link directly to a specific ZeeML calculator or AI studio? Yes. Every workstation has a permanent, self-referencing canonical URL and an accompanying .md Markdown twin with explicit mathematical formulas and step-by-step benchmark traces. --- - Canonical Web App: https://zeeml.com/tools - LLM Context Manifest: https://zeeml.com/llms.txt - Full Platform Knowledge Base: https://zeeml.com/llms-full.txt
