LLM (Large Language Model)
A machine learning model trained on large amounts of text that can understand and generate human language. LLMs are the underlying technology in AI assistants like ChatGPT and Claude, and are used to power AI tools in home care software.

A Large Language Model (LLM) is a deep learning model trained on vast amounts of text that develops the ability to understand language, follow instructions, reason through problems, and generate coherent text. LLMs serve as the reasoning engine inside AI assistants and AI agents.
In home care applications, LLMs can power documentation assistance (turning voice notes into care summaries), scheduling reasoning (understanding natural language requests), training content generation, and client communication drafting.
LLMs have limitations: they can hallucinate (generate plausible but incorrect information), their knowledge has a training cutoff date, and they may not reflect the most current state regulations or payer policies.
In home care, this means…
The core reasoning component of most AI tools. Home care operators evaluating AI vendors should ask which LLM powers a product and what guardrails are in place for accuracy and HIPAA compliance.

AI Agent →
An autonomous software system that can perceive context, reason, make decisions, and take multi-step actions to complete goals — going beyond a single chatbot response to execute workflows, call tools, and coordinate with other systems.
Shadow AI →
The unsanctioned use of consumer AI tools (such as ChatGPT or Claude) for work purposes by employees, without agency approval or HIPAA safeguards. Shadow AI is a significant and growing compliance risk in home care.
HIPAA →
The Health Insurance Portability and Accountability Act — federal law establishing privacy and security standards for protected health information (PHI). Home care agencies that handle client health data must comply with HIPAA's Privacy and Security Rules.
Neuro-Symbolic AI →
A hybrid AI approach combining neural network pattern recognition (like LLMs) with symbolic reasoning (rules, logic, and constraints). This combination is well-suited to home care applications that require both language understanding and strict regulatory compliance.
Workflow Automation →
The use of software to execute multi-step business processes automatically, reducing manual work and human error. In home care, workflow automation applies to scheduling, billing, compliance tracking, and caregiver onboarding.
