SchemaKyma Guide
Learn how to structure clinical algorithms effectively.
Last updated: 2026-03-15Quick Start
Build your first schema in 3 steps.
1. Add a Chief Complaint (CC) Node
Press the + button in the editor to add your first node. Set the category to 'CC' and enter the symptom.
2. Add Category Nodes
Use System, Diagnosis, Workup, Treatment, and other categories to build your diagnostic pathway.
3. Connect with Edges
Drag from the bottom handle of a node to connect it to another. Add condition labels to make pathways clear.
Using the Editor
Master nodes, edges, shortcuts, and export features.
Node Categories (6 types)
CC (Chief Complaint) — Starting point of the algorithm
System — Organ system classification
Diagnosis — Differential diagnoses
Workup — Required investigations
Treatment — Treatment options
Emergency — Red flag findings requiring immediate attention
Working with Edges
Drag from a node's bottom handle → connect to target node
Click an edge → add a condition label (e.g., 'positive', 'negative')
Select an edge → press Delete/Backspace
Keyboard Shortcuts
Ctrl/Cmd + Z — Undo
Ctrl/Cmd + Shift + Z — Redo
Delete/Backspace — Delete selected node/edge
Auto-save — Saves 0.8s after each change
Export
PDF — High-resolution print output (Pro: no watermark)
Try 'Hide edges' and 'Hide background colors' options before exporting.
AI Features Guide
Understand the 5 AI functions and use them effectively.
AI Function Selection Guide
Create a new schema from scratch → Generate
Add diagnoses to existing schema → Chat
Modify around a specific node → Incremental Chat
Check schema completeness → Analyze
Improve AI-generated results → Refine
Generation Presets
Light — 3-5 key differentials, quick overview
Standard — 7-12 differentials by system, includes workup/treatment
Detailed — 15+ differentials, comprehensive workup included
Tips for Better AI Results
Be specific with the chief complaint (e.g., 'chest pain' → 'exertional chest pain')
Select an existing node before chatting to focus modifications around it
Click 'Apply' on analysis results to auto-implement suggestions
Virtual Patient (CPX/OSCE) Practice
Learn effective history-taking strategies and scoring tips.
High-Score History-Taking Strategy
Follow the LOST CoEx CF Asso sequence for systematic history-taking.
L: Location, O: Onset, S: Severity, T: Timing (duration/intermittent)
CoEx: Concurrent & Exacerbating factors
CF: Constitutional & Family history
Asso: Associated symptoms
Scoring Structure (100 points)
History Taking (40 pts) — Systematic questioning, key items covered
Physical Examination (15 pts) — Relevant examination mentioned
Patient Education (15 pts) — Disease explanation, test guidance, lifestyle advice
Differential Diagnosis (15 pts) — Appropriate diagnostic list
Communication (15 pts) — Empathy, listening, professionalism
Common Mistakes
Suggesting a diagnosis too early with leading questions
Using only closed-ended questions without open-ended ones
Ignoring patient emotions and asking mechanically
Community & Sharing
Share your schemas and learn from others.
Sharing
Public — Visible in community, searchable and clonable
Unlisted — Accessible only via direct link
Cloning
Clone schemas you like to your dashboard and modify them freely.
Reactions
Leave likes or dislikes to provide feedback and help maintain community quality.
For Educators
Learn how to use SchemaKyma in your classroom.
Classroom Usage
Assign students to build differential diagnosis algorithms for specific chief complaints.
Example 1: 'Create a DDx algorithm for chest pain and share it on the community.'
Example 2: 'Compare your schema with the official template and explain the differences.'
Monitoring Student Progress
Check student-shared schemas in the community tab and provide feedback.
Recommended Workflow
1. Instructor provides official templates (unlisted links)
2. Students build their own schemas
3. Use AI analysis for self-assessment
4. Share on community for peer comparison and feedback
FAQ
Where is my data stored?
Schema data is stored in your browser's local storage. When signed in, it automatically syncs to the cloud (Firebase) so you can access it from any device.
What's the difference between Free and Pro?
Free: 20 schemas, 35 AI calls/day. Pro: unlimited schemas, 350 AI calls, watermark-free PDF, CPX virtual patient. See /pricing for details.
Can I use it offline?
Yes, schemas stored locally can be edited offline. They'll sync automatically when your connection is restored.
Which browsers are supported?
Chrome, Safari, Firefox, and Edge (latest versions). iPad touch interactions are also optimized.
How do I delete my account?
Currently, please email schemachema.help@gmail.com. Self-service account deletion is planned for a future update.
Where can I send feedback?
Email schemachema.help@gmail.com or leave feedback directly in the community.
