Convert your notes, PDFs, and lectures into accurate practice exams. Get graded instantly with zero mistakes, and pass your certifications with confidence.
Multiple-choice guesses hide real knowledge gaps. Meanwhile, generic AI study tools grade responses using flaky LLM prompts, leading to false negatives on equivalent equations and code configurations.
Generic AI tools grade equations using token probabilities. They mark equivalent expressions wrong—penalizing correct math because it differs from the exact text-match pattern.
Multiple-choice options permit guesswork and test memorization, not application. They cannot simulate the active problem-solving demanded by official Cisco CLI router consoles.
Educators lose formatting, equations, and interactive elements when migrating exams between different LMS platforms. There is no simple way to preserve technical question metadata.
Refraxi extracts concepts from your materials, structures them into modular topics, and grades practice outputs inside sandboxed terminal consoles and computer algebra engines.
Drag-and-drop course PDFs, syllabus files, or paste public documentation and YouTube links.
The parser processes content and isolates key curriculum nodes to prevent exam hallucinations.
Practice command inputs using mock CLI terminals and verify equations with symbolic math engines.
Mistakes feed directly into a customized deck designed to reinforce facts using active recall.
Practice router configuration syntax in a mock command-line interface. Refraxi validates command inputs via pattern matching to prepare you for console exams.
Test the SandboxOur engine uses SymPy to evaluate algebraic answers symbolically. Whether you enter 1/2 or 0.5, the computer algebra system checks for true mathematical equivalence without LLM guesswork.
Enter Equation EditorEmbed exams directly inside Canvas or Moodle. Synchronize student rosters and export grades automatically with zero API configuration.
Sync Your LMSConvert exam mistakes into active-recall flashcards. Review intervals adapt automatically based on your individual retention speed.

Honest explanations of how we grade responses, integrate with institutional platforms, and secure student telemetry.
We do not use LLMs to grade mathematics. Refraxi parses formulas into the SymPy symbolic mathematics library. SymPy determines whether your expression is algebraically equivalent to the answer key, meaning variations like 1/2 and 0.5 are both scored correctly.
No. We do not use webcam proctoring, microphone recordings, or screen monitoring. Refraxi tracks focus telemetry only (whether the exam tab goes out of focus) if enabled by the instructor. We prioritize user privacy.
The Sandbox plan is free forever. It includes manual quiz building up to 50 questions per exam, 3 AI-powered exam builds per month, and full access to spaced repetition study decks. Premium features like ConceptMaps, terminal labs, and LMS syncing are available on paid tiers.
Instructors can link Refraxi assessments directly into Canvas, Moodle, or Blackboard. Roster mapping is handled dynamically when students access the assignments, and exam grades are passed back directly to the LMS gradebook.
Convert your notes, manuals, or slides into realistic, deterministic practice tests in under 60 seconds.
