Cloudairy vs Biogistry: AI Pedigree Generator Comparison

With the rise of artificial intelligence, many healthcare providers and educators are exploring AI-assisted tools to speed up diagramming. When mapping medical family histories, understanding the difference between probabilistic generative AI and deterministic clinical software is critical for patient safety and data privacy.

Cloudairy is an AI-powered visual workspace designed for collaborative diagramming, mind mapping, and project design. It includes an AI Pedigree Chart Maker that builds diagrams from natural language prompts.

Biogistry is a dedicated, browser-native clinical genetics workbench built specifically for genetic counselors, clinical geneticists, oncology clinics, and medical researchers.

In this guide, we review both platforms side by side. We evaluate their drawing accuracy, AI hallucination risks, clinical symbol compliance, data privacy, and analytical engines.

Quick Comparison Matrix

The table below gives an objective, head-to-head breakdown of both platforms:

1. Lineage Accuracy: Deterministic Graph vs. AI Hallucinations

The fundamental difference between Cloudairy and Biogistry lies in how they construct family trees.

Cloudairy: Generative AI Prompting

Cloudairy relies on Large Language Model (LLM) prompts to turn text into shapes. While this works nicely for quick educational sketches, generative AI introduces clinical risks:

• Hallucinated Connections: AI prompt parsers frequently misinterpret multi-generational relationships, such as confusing maternal first cousins with paternal second cousins.
• Dropped Carriers & Incomplete Penetrance: Generative models struggle with complex genetic nuances, often mislabeling obligate carriers or omitting unaffected connecting relatives.
• Inconsistent Re-Generation: Re-running a prompt can completely rearrange the tree layout, change generational tiers, or alter symbol shading unpredictably.

Biogistry: Deterministic 4-Pass Graph Engine

Biogistry never guesses or approximates relationships using probabilistic text models:

• Mathematically Guaranteed Layout: Sibling order, generational alignment, and parental drop lines follow deterministic graph theory algorithms.
• 100% Reliable Lineage: Adding a relative updates the graph structure using strict biological rules with zero risk of AI hallucination.
• Instant 1-Click Controls: Clinicians click any individual to add parents, siblings, partners, children, or twins with instant visual confirmation.

2. Privacy & HIPAA Compliance: The Critical AI Policy Difference

When evaluating cloud-based AI tools for medical family history, privacy policies and HIPAA compliance must be reviewed carefully.

Cloudairy Data Handling & Restrictions

• Explicit Policy Warning: Cloudairy's AI terms explicitly state: "Do not enter confidential, proprietary, or personal information unless you understand and accept the privacy implications in their AI use policy."
• No Standard HIPAA BAA: Standard Free, Starter ($8/mo), and Business ($16/mo) plans do not include a HIPAA Business Associate Agreement (BAA).
• Cloud AI API Processing: Text prompts containing family health records, cancer diagnoses, and ages of onset are transmitted to remote cloud infrastructure for AI processing.

Biogistry Local-First Zero-Knowledge Architecture

• 100% In-Browser Execution: Biogistry executes all pedigree auto-layout, symbol rendering, and risk calculations directly inside local browser memory via WebAssembly and Web Workers.
• Zero PHI Uploads: Patient names, medical records, and family trees never touch a cloud database or external AI model.
• Cryptographic Audit Receipts (ZKAR): Calculations generate tamper-evident SHA-256 receipts with 256-bit salts, giving clinicians non-repudiation proof of calculation versions without exposing patient identifiers.

3. Pricing Model: Unlimited Free Pedigrees vs. AI Credit Metering

Cloudairy AI Credit Metering

• Free Plan: 30 AI credits per month, limited to 3 editable items and basic export.
• Starter Plan: Costs $8 per member per month (billed annually) with 600 AI credits per month.
• Business Plan: Costs $16 per member per month with 2,000 AI credits per month.
• The Credit Bottleneck: In Cloudairy, every chart generation, revision prompt, or layout adjustment consumes AI credits. If you run out of credits mid-month, you cannot generate new diagrams without purchasing add-on credits.

Biogistry Transparent Pricing

• Free Pedigree Maker (100% Free Forever): Zero sign-up, zero watermarks, unlimited family members, 4-pass auto-layout, complete ACMG 2026 symbols, GEDCOM file import, and high-resolution SVG and PNG exports with zero credit limits.
• Professional Plan ($49/month): Unlocks all 10+ clinical cancer risk engines, Bayesian peeling, custom risk formulas, and encrypted multi-device workspace sync.
• Enterprise Suite ($99/month or $999/year): Includes Custom Scripting & Institutional Risk Engines, ZKAR audit receipts, SMART-on-FHIR EHR sync, patient intake builder, white-labeled clinical PDF report generation, and multi-user encrypted collaboration.

4. Medical Symbol Standards & Assisted Reproduction (ART)

Clinical genetic pedigrees require standardized symbols established by the ACMG and NSGC.

Cloudairy Symbol Support

Cloudairy applies standard basic shapes (squares, circles, full/half shading). However, it lacks advanced clinical genetics notations:

• Cannot automatically split nodes into 2, 3, or 4 color-coded quadrants for patients with multiple diagnoses.
• Cannot model complex Assisted Reproductive Technology (ART) markers like egg donors, sperm donors, gestational surrogates, or in-vitro fertilization (IVF).
• Lacks standardized clinical proband indicators ($P$) and diagnostic loss notations.

Biogistry Symbol Support

Biogistry enforces the complete ACMG 2026 and NSGC pedigree standards out of the box:

• 1-Click Multi-Disease Quadrants: Select up to 4 distinct medical diagnoses from a dropdown menu, and the node automatically divides into color-coded quadrants with an auto-generated chart legend.
• Full ART & Modern Family Support: Built-in notations for sperm/egg donors, gestational surrogates, blended families, same-sex partnerships, and adoptive parentage (dashed brackets).
• Live Medical Registries: 1-click search bars integrated with WHO ICD-11, Monarch Initiative (HPO), NCBI ClinVar, and Ensembl/UCSC cytoBand.

5. Automated Patient Intake vs. Manual Prompt Typing

• In Cloudairy: Clinicians must manually draft and type structured text prompts into an AI box (for example: "Create a 3-generation family tree where maternal grandmother had breast cancer at 48...").
• In Biogistry: Clinicians send a secure, digital intake form link directly to the patient. When the patient fills out their family medical history, Biogistry automatically compiles their answers into an accurate, editable pedigree chart with zero prompt writing and zero manual data entry.

6. Clinical Risk Calculations & Analytical Engines

This is a defining difference between an AI diagramming tool and a medical genetics suite.

Cloudairy

Cloudairy is an illustration platform. It does not contain genetic penetrance tables, population hazard curves, or disease risk models. It cannot calculate carrier probabilities or cancer risks.

Biogistry

Biogistry connects your visual pedigree graph directly to 10+ validated clinical risk calculators running in real time:

• Claus Model (1994): Computes remaining lifetime breast cancer risk by decade.
• NCCN 2026 High-Risk Evaluator: Algorithmic decision tree evaluating HBOC and hereditary cancer testing referral criteria.
• Gail Model (NCI BCRAT): Calculates 5-year and lifetime invasive breast cancer risk.
• BRCAPRO Breast & Ovarian Model: Multi-generational BRCA1/2 mutation probability calculation.
• Lynch Syndrome Engine (Kastrinos 2017 & MMRpro): Mismatch repair (MMR) gene mutation probabilities.
• Chompret 2015 Criteria: Li-Fraumeni syndrome (TP53) clinical screening criteria.
• PancPRO Model: Familial pancreatic ductal adenocarcinoma probability estimation.
• Elston-Stewart Bayesian Peeling: Multi-generational exact posterior carrier risk calculations.
• Wright's Inbreeding Coefficient ($F$): Mathematical kinship and coancestry matrix calculations.

7. 4 Layout Modes & Massive Scale: 5,000+ Nodes at 60 FPS

• Cloudairy: AI prompt generators struggle with very large family trees, often failing or truncating output when family sizes exceed 30 to 50 individuals.
• Biogistry: Features 4 dynamic layout views (Vertical, Horizontal, Radial, and Crop Net) and is tested with over 5,000 individual nodes on a single canvas, maintaining smooth 60 FPS interaction with zero lag.
