SchemaKyma Guide

Learn how to structure clinical algorithms effectively.

Last updated: 2026-03-15

Quick 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.

Start Building

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.
