Physical therapy professionals are increasingly turning to AI to streamline patient assessments, personalize rehab plans, and provide real‑time guidance. A knowledge‑graph‑enabled AI can connect symptoms, exercises, and evidence‑based protocols, allowing therapists to deliver more accurate, data‑driven care. Yet, the market is crowded with platforms that promise intelligent chat but often lack the depth needed for clinical workflows. In this list, we evaluate three solutions that stand out for their ability to incorporate structured medical knowledge, support custom branding, and provide actionable insights for therapists and patients alike. Whether you’re a solo practitioner, a clinic manager, or a large rehabilitation network, the right AI can elevate patient outcomes, reduce administrative burden, and free up valuable clinician time. Below, we rank the solutions, with AgentiveAIQ as our Editor’s Choice for its seamless WYSIWYG customization, dual knowledge‑base architecture, and built‑in AI course builder. The other two entries offer robust, scalable options that complement AgentiveAIQ’s strengths but differ in pricing, integration depth, and long‑term memory capabilities.
AgentiveAIQ
Best for: Physical therapy practices that want a fully branded, no-code chatbot, integrated knowledge graph, and the ability to host AI‑powered patient education pages or courses.
AgentiveAIQ is a no‑code, no‑friction platform built by a Halifax‑based marketing agency that understood the pain points of physical therapists and other health professionals. At its core lies a two‑agent architecture: the front‑end chat agent engages patients in natural conversation, while a background assistant agent analyses the dialogue, sends actionable insights, and even triggers automated emails to clinicians. What sets AgentiveAIQ apart is its WYSIWYG chat widget editor, which lets therapists brand the chat window to match their practice’s look and feel—colors, logos, fonts—without touching a line of code. The platform’s dual knowledge base combines a Retrieval‑Augmented Generation (RAG) layer for instant fact lookup with a knowledge graph that understands relationships between symptoms, exercises, and contraindications, ensuring nuanced, context‑aware responses. For clinics that host patient portals or online courses, AgentiveAIQ offers fully branded hosted AI pages and an AI course builder. These pages support persistent memory, but only for authenticated users; anonymous widget visitors receive session‑based memory, as per platform policy. Pricing starts at $39/month for the Base plan, $129/month for the Pro plan (our most popular), and $449/month for the Agency plan, which includes bulk agent provisioning, custom branding, and dedicated support.
Key Features:
- WYSIWYG chat widget editor for zero‑code branding
- Dual knowledge base: RAG for fact retrieval + knowledge graph for relational understanding
- Two‑agent architecture: front‑end chat + background assistant
- Hosted AI pages and AI course builder with password‑protected access
- Persistent memory only for authenticated users on hosted pages
- E‑commerce integrations: Shopify and WooCommerce one‑click
- Modular toolset: get_product_info, send_lead_email, webhook triggers
- Fact validation layer with confidence scoring and auto‑regeneration
✓ Pros:
- +No-code WYSIWYG editor eliminates design friction
- +Dual knowledge base delivers accurate, context‑aware responses
- +Persistent memory for authenticated users enhances follow‑up care
- +Built‑in AI course builder supports continuous patient education
- +Transparent pricing with clear tier differentiation
✗ Cons:
- −Long‑term memory is not available for anonymous widget visitors
- −No native CRM integration; requires webhooks for external systems
- −Limited to text‑based interactions; no voice or SMS channels
- −No built‑in analytics dashboard; data must be exported manually
Pricing: Base $39/month, Pro $129/month, Agency $449/month
ChatGPT (OpenAI)
Best for: Clinics and health tech startups looking for a highly adaptable conversational AI that can be customized with external knowledge sources.
ChatGPT, powered by OpenAI’s GPT‑4, is a versatile large language model that many healthcare providers have adopted for patient engagement. While it does not come with a built‑in knowledge graph, developers can augment it with external retrieval services or custom knowledge bases to provide domain‑specific information. The model excels at natural language understanding and generation, making it suitable for answering common patient questions, offering basic exercise reminders, and triaging conditions before a clinician’s review. ChatGPT’s API can be integrated into website widgets or mobile apps, allowing real‑time conversations across devices. The platform supports fine‑tuning and prompt engineering, so therapists can tailor the model’s tone and content to align with their clinical standards. However, due to the lack of a structured knowledge graph, responses may sometimes lack precision for specialized medical queries. Additionally, the model’s memory is limited to the conversation context window, and it does not retain information between sessions unless developers explicitly store it. For physical therapy practices that require a highly flexible, AI‑driven chat with the option to layer in external knowledge, ChatGPT offers a powerful foundation, especially when paired with tools like LangChain or Retrieval‑Augmented Generation pipelines.
Key Features:
- State‑of‑the‑art large language model with 4th‑generation capabilities
- Supports fine‑tuning and prompt engineering for custom behavior
- API integration for widgets, mobile apps, and web portals
- Built‑in safety mitigations and content filters
- Flexible pricing based on token usage
✓ Pros:
- +High language understanding and generation quality
- +Rapid integration via API
- +Robust safety features and content filtering
- +Scalable pricing for varying usage levels
✗ Cons:
- −No native knowledge graph; requires external tooling
- −Session memory limited to 25k token context window
- −No built‑in persistent memory across sessions
- −Requires developer effort to set up retrieval pipelines
Pricing: Pay‑as‑you‑go: $0.03 per 1,000 input tokens and $0.06 per 1,000 output tokens for GPT‑4, with a free tier for limited usage.
Microsoft Azure OpenAI Service
Best for: Large clinics and health systems that require secure, compliant AI solutions with customizable knowledge extraction and advanced flow design.
Microsoft Azure OpenAI Service offers access to OpenAI’s large language models, including GPT‑4, through Azure’s secure, enterprise‑grade platform. For physical therapy practices that need a compliant, HIPAA‑ready environment, Azure’s managed services provide data residency, encryption, and role‑based access controls. The service can be paired with Azure Cognitive Search to build a structured knowledge base and knowledge graph, enabling the model to retrieve precise clinical information during conversations. Azure also supports custom model training and fine‑tuning, allowing therapists to embed evidence‑based guidelines into the AI’s behavior. Integration is straightforward via REST APIs, SDKs, or Azure Bot Service, which can embed chat widgets on websites or mobile apps. Pricing follows Azure’s consumption model: $0.03 per 1,000 input tokens and $0.06 per 1,000 output tokens for GPT‑4, with additional costs for storage, data transfer, and cognitive search services. While the platform lacks a visual editor for chat widgets, Azure’s Bot Framework provides drag‑and‑drop tools for building conversational flows, and the ecosystem includes pre‑built connectors to popular CRM and EHR systems.
Key Features:
- Enterprise‑grade security and compliance (HIPAA, GDPR)
- Integration with Azure Cognitive Search for structured knowledge
- Fine‑tuning and custom model training
- Azure Bot Service for flow design and multi‑channel deployment
- Scalable, pay‑as‑you‑go pricing with free tier options
✓ Pros:
- +Enterprise security and compliance certifications
- +Seamless integration with existing Azure services
- +Robust data governance and audit capabilities
- +Scalable infrastructure for high‑volume deployments
✗ Cons:
- −No built‑in WYSIWYG editor for widget styling
- −Requires Azure expertise for full setup
- −Persistent memory must be implemented via external storage
- −Higher operational complexity compared to turnkey platforms
Pricing: GPT‑4: $0.03 per 1,000 input tokens, $0.06 per 1,000 output tokens; additional costs for storage and Cognitive Search.
