Free Chatbot: 8 Best Tools for Businesses in 2026

Are There Quality Free Chatbots?

Yes, they exist. But you must understand the model before diving in: the vast majority of free chatbot platforms work under a freemium scheme. They offer you a plan at no cost so you can try the tool, validate if it fits your use case, and when you grow, upgrade to a paid plan. It's an honest model as long as you know where the limits are.

Free options are perfect for three specific scenarios: prototyping a conversational flow before investing, validating if a chatbot actually reduces load on your support team, or covering the needs of a small business with low query volume. For a complete view of how chatbots fit into business strategy, check our guide on business chatbots.

Common limits of free plans affect three areas: number of conversations or messages per month, number of stored contacts, and access to advanced artificial intelligence functionalities. A free online chatbot will serve you to start, but don't expect it to support 5,000 monthly conversations with advanced NLP without paying.

Comparison Table: 8 Free Chatbots in 2026

Before diving into each tool, this table summarizes the essentials. Each column answers a question every company asks when looking for a free chatbot for website or messaging channels.

All listed tools support free Spanish chatbot, though NLP quality in Spanish varies significantly between them. Tidio and Botpress offer the best language understanding thanks to their integrations with advanced language models. Tawk.to stands out as the only completely free option without volume restrictions, though it lacks conversational AI: it's a pure live chat system with human operators.

If your main channel is WhatsApp, also check specific options in our free WhatsApp chatbot guide. For those looking to build from scratch with more control, we have a complete guide to create a chatbot.

Top 3: Detailed Analysis

Tidio: Best All-in-One

Tidio combines live chat, flow-based chatbot, and its own AI engine, Lyro AI, in a single platform. The free plan includes 100 Lyro conversations per month, enough for an SMB receiving 3-5 queries daily. The visual flow editor is intuitive and requires no code. It natively integrates with Shopify, WordPress, and WooCommerce.

• Pros: clean interface, decent Spanish AI, ecommerce integration.
• Cons: 100 AI conversations fall short if you have medium-high traffic.
• Ideal for: small online stores and service companies with low volume.

Botpress: Best for Developers

Botpress is the most powerful option for technical teams that want to create free chatbot with advanced capabilities. Its engine natively integrates GPT, offers a visual flow editor with complex conditional logic, and allows omnichannel deployment. The free plan includes 2,000 messages per month and full access to the editor.

• Pros: powerful native AI, omnichannel deployment, active community.
• Cons: steeper learning curve than Tidio or ManyChat.
• Ideal for: development teams that need a chatbot with real conversational AI and control over logic.

HubSpot Chatbot: Best for Integrated CRM

HubSpot offers a chatbot builder within its free CRM. The competitive advantage isn't in AI (it uses rule-based flows, not advanced NLP) but in native CRM integration: each conversation creates or updates a contact, records the interaction, and can trigger marketing or sales workflows automatically. No conversation limit on the basic plan.

• Pros: integrated CRM, no volume limit, automation workflows.
• Cons: no conversational AI in free plan, only rule flows.
• Ideal for: companies already using HubSpot or needing the chatbot to directly feed their commercial pipeline.

When to Upgrade from Free to Paid

The free plan is a starting point, not a destination. These are the signals that you've exceeded free tier limits:

• Volume: you consistently exceed the monthly conversation or contact limit.
• Integrations: you need to connect the chatbot with your CRM, ERP, or ticketing platform.
• Advanced AI: rule flows no longer resolve your customers' queries and you need real NLP.
• Multiple agents: more than one human operator needs to manage conversations simultaneously.
• Analytics: you need performance metrics, resolution rates, and average response time to report results.
• SLA: your business requires availability guarantees and priority technical support.

The next natural leap isn't simply a paid chatbot, but evolving towards an AI agent capable of resolving complex queries, executing actions in your systems, and learning from each interaction. The difference between an advanced chatbot and an AI agent is that the second doesn't just respond: it acts. For companies managing customer support at scale, that difference is critical.

Frequently Asked Questions

What is the best free chatbot in Spanish?

For companies looking for a free Spanish chatbot with AI, Tidio offers the best balance between ease of use and Spanish comprehension quality. If you need more message volume without code, Botpress with its 2,000 monthly messages is the most solid alternative.

Is Tawk.to really free?

Yes. Tawk.to is 100% free without limits on agents, conversations, or contacts. Its business model is based on optional additional services like hired agents and premium support. It doesn't include conversational AI: it's live chat with human operators.

Can I use ChatGPT as a chatbot for my website?

Not directly. ChatGPT doesn't offer an embeddable chat widget for web. You need to use the OpenAI API and integrate it with a platform like Botpress or custom development. That implies token costs for each processed message. For a functional chatbot on web and WhatsApp without custom development, production-ready solutions exist.

GuruSup allows you to deploy AI agents on WhatsApp and web that resolve real customer queries, not just canned responses. Without custom development, with direct CRM integration and native Spanish support. Try GuruSup for free and move from basic chatbot to the agent your support team needs.
