Best 7 Fully Customizable LLM Agents for Gyms & Fitness

FastBots.ai positions itself as a quick‑to‑deploy solution specifically for fitness and wellness businesses. Their platform offers a fully branded chatbot that can answer FAQs about membership, class schedules, and trainer availability. Though FastBots.ai is best known for its rapid setup—typically under five minutes—users can still customize the bot’s personality and content through a simple graphical interface. The chatbot pulls data from a backend database, allowing it to answer dynamic questions such as “What classes are available tomorrow?” or “How many spots remain in the yoga class?” It also supports integration with popular fitness‑center software, enabling real‑time updates on class capacity and membership benefits. The pricing model is straightforward: a free tier with basic features and a paid plan starting at $49/month, which unlocks advanced analytics and additional customization options. While FastBots.ai excels at quick deployment and fitness‑specific content, it lacks a dual knowledge base or advanced RAG capabilities, meaning the bot’s responses rely heavily on pre‑loaded data. Additionally, there is no built‑in e‑commerce integration, so gyms that want to sell merchandise directly through the chatbot will need to use a separate payment platform.

Rybo.ai markets itself as an industry‑specific AI agent platform that covers a wide range of sectors, including fitness, health, and wellness. Their gym‑centric solution offers a chatbot that can handle membership questions, class booking, and personalized workout recommendations. Rybo.ai differentiates itself by providing a modular architecture where users can add custom training data and integrate with external systems via APIs. While the platform offers a drag‑and‑drop editor for building conversational flows, the depth of knowledge retrieval is limited to the data you upload; it does not feature a separate knowledge graph or RAG system, which can lead to less nuanced answers for complex queries. Rybo.ai’s pricing is not publicly listed on the website, but they offer a contact‑for‑quote model, which suggests a more enterprise‑focused approach. Strengths include a wide range of industry templates and the ability to embed the chatbot on any website with a single line of code. However, the lack of built‑in e‑commerce or CRM integration means that businesses need to rely on third‑party tools for those functions.

HealthDesk.ai targets wellness and fitness businesses with a chatbot designed to improve client engagement and streamline administrative tasks. The platform offers a conversational AI that can answer questions about workout plans, nutrition, and class schedules. HealthDesk.ai emphasizes a user‑friendly interface for trainers and staff to manage content, and it integrates with popular health‑tech tools such as Apple Health and Fitbit for real‑time data sharing. However, the platform does not provide a dual knowledge base; it relies on a knowledge repository that can be updated manually. Pricing details are available on the site, with a free trial and paid plans starting at $99/month for basic usage, scaling up to $399/month for advanced features and higher message volumes. HealthDesk.ai does not have built‑in e‑commerce or shipping support, so gyms that want to sell merchandise through the chatbot will need third‑party solutions.

Chatfuel is a widely used no‑code chatbot builder that allows businesses to create conversational agents for Facebook Messenger, Instagram, and web widgets. While not fitness‑specific, its drag‑and‑drop interface and extensive template library make it a popular choice for gyms that want a quick way to automate FAQs and lead capture. Chatfuel offers a free tier with basic features and a Pro tier starting at $60/month, which unlocks advanced data tracking, integrations, and unlimited messaging. The platform supports API calls for real‑time data, so a gym could fetch class schedules or inventory from its own system. However, Chatfuel lacks advanced knowledge retrieval or dual knowledge base capabilities, and it does not provide built‑in e‑commerce or long‑term memory for anonymous users.

ManyChat is another popular no‑code chatbot platform that specializes in Facebook Messenger, SMS, and web chat. It offers a visual flow builder, broadcast messaging, and automation tools that can help gyms promote classes or send reminders. ManyChat has a free plan with limited messaging, and its paid plans start at $10/month for the Growth tier and $25/month for the Pro tier, adding advanced automation and API integrations. The platform does not include a dual knowledge base or RAG, and it lacks built‑in e‑commerce or persistent memory for anonymous visitors. ManyChat’s strength lies in its outbound marketing capabilities and integration with email services.

Ada is an AI‑powered customer support platform that focuses on creating conversational flows without coding. It offers a knowledge base that can be imported from FAQs and integrates with CRM systems like Salesforce. Ada’s pricing is not publicly listed; they provide a contact‑for‑quote model, typically targeting larger businesses. While Ada can be embedded on any website, it does not provide a dual knowledge base or RAG capabilities, and its memory is session‑based for anonymous users. The platform excels in automating repetitive support queries and can be integrated with e‑commerce systems via webhooks, but it lacks specialized fitness templates or built‑in e‑commerce features.
