Free Chatbot for Website: 8 Best Tools to Try in 2026

A free chatbot for website pages can help you answer questions, guide visitors, and reduce repetitive tasks before you commit to a paid platform.

The problem is that "free" can mean very different things.

Some tools are free forever, some offer a generous free plan, and some give you a free version that loses the AI features you actually want after the first test.

We reviewed eight tools worth trying in 2026 for teams that want a free website chatbot that can support real customer interactions.

We'll look at what each tool offers for free, how it learns from your website content, how easy it is to launch, and where the first limitations usually appear.

2. Tidio
3. Chatling
4. HubSpot

What to Look for in a Free Chatbot for a Website#

A free website chatbot should cover a few things before you add it to your site.

Start with the pricing model, because some tools are completely free, some are free forever, and some only give you a free version with limited AI features.

The chatbot should also learn from website URLs, uploaded documents, or a knowledge base, so it can answer questions from your own content.

Setup should stay simple, with a short embed path and a free widget that does not force a full rebuild. It also helps to check whether the tool supports lead capture, live agent handoff, or routing to the right team member when the bot cannot handle the request on its own.

Finally, look at the limits early, including branding, message caps, missing advanced features, and other key features that affect how well the chatbot handles customer questions and guides users through the next step.

8 Best Free Chatbots for Websites#

This list looks at tools that give you a real free option, not just a short demo.

The comparison also weighs how each chatbot builder learns from website content, how quickly you can add the chat widget, whether it supports lead capture or live chat, and how clearly the paid tiers are explained.

We've also looked at whether the tool can handle only simple user queries or grow into customer support, customer engagement, and higher-volume tasks later on.

Let's get deeper into each one.

1. Denser#

Denser is built for teams that want a free chatbot for website pages to answer real questions from real content, not generic AI guesses.

It combines no-code deployment with conversational AI trained on website URLs, PDFs, DOCX, PPTX, Google Drive files, and curated FAQs, so website visitors can get cited answers instead of waiting for someone on your team to write emails back manually.

Denser can crawl up to 100K+ pages, support 80+ languages, and go live with a single embed snippet. You can test replies in the dashboard, click citations to verify answers, fine-tune the AI prompt, adjust branding, capture leads with custom forms, review chat logs, and improve weak answers by saving revisions back into FAQs.

On higher plans, Denser also adds REST API access and database chat, giving teams more ways to automate tasks, build custom knowledge bases, and manage workflows from one place.

Denser is best for teams that want an effective chatbot for support, lead capture, product education, or access to technical knowledge from the same system.

It suits SaaS companies, ecommerce brands, service businesses, and lean support teams that need website visitors to get fast, verifiable answers while the team focuses on higher-value work rather than repeating FAQs, digging through docs, or writing emails one by one.

Standout Features & Unique Capabilities of Denser#

• Crawl and index up to 100K+ pages, so the chatbot can answer from a full website instead of a thin FAQ set.
• Show source citations in every reply, so users can verify exactly where the answer came from.
• Capture leads with customizable forms and sync submitted data into connected workflows such as Google Sheets.
• Review chat logs, revise weak replies, and save improved answers back into FAQs to keep the bot getting better over time.
• Customize the chatbot's look, prompt behavior, and deployment path across website embed, WordPress, Shopify, Slack, Zapier, API, and database-connected use cases.

Pros#

• Cited answers make it easier to trust what the bot returns on live website questions.
• Website deployment and chatbot training feel easy to handle without a complicated rollout.
• Lead generation and document-based support both work from the same product, which gives teams more range from one chatbot.

Pricing#

• Free: $0/month
• Starter: $29/month
• Standard: $119/month
• Business: $399/month
• Enterprise: Contact sales

All plans have a 20% discount when paid yearly.

2. Tidio#

Tidio combines a live chat widget, a help desk, and a Lyro AI agent into one product. You can train the bot on verified data sources, route customer interactions to a shared inbox, and use automation flows to handle repetitive tasks before they become support tickets.

The platform also includes visitor tracking, product recommendations, and multilingual support, which makes it useful for small businesses that want one place for chat, tickets, and light automation.

The free plan gets you started, while paid tiers expand usage and AI access. Tidio offers a short, full-featured trial first, then reverts the account to the free version. That structure helps teams test more features before deciding whether the paid plan matches their support volume.

Standout Features & Unique Capabilities of Tidio#

• Train Lyro on verified sources so the AI handles simple user queries with fewer off-topic replies.
• Use one workspace for AI, live chat, ticketing, and a shared inbox.
• Add product suggestions and active flows for sales or support journeys.

Pros#

• Live chat and AI automation sit in one interface, which helps teams manage support and chat flows from the same place.
• Real-time engagement tools help teams answer routine questions faster while keeping conversations active.
• Customer support gets high marks, especially during onboarding and early integration work.

Cons#

• Pricing becomes a problem for smaller teams once they need more customization or higher AI usage.
• Some useful AI and chatbot options are locked behind more expensive plans.
• Customization is not as flexible as some teams want, especially for more tailored workflows.

Pricing#

• Free: $0/month
• Starter: $29/month
• Growth: $59/month
• Plus: $749/month
• Premium: Custom pricing

3. Chatling#

Chatling centers its product around AI chatbots trained on website URLs, FAQs, files, and help content. You can build a bot without coding, connect it to your site, and use it for lead capture, support, and knowledge base search.

Image Source: chatling.ai

The platform also supports multiple AI models, live chat, analytics, multilingual support, and a visual editor, which gives non-technical teams a faster path from setup to launch.

One detail that separates Chatling from many free-to-start tools is unlimited chats on its published plans. The free plan is usage-bound through AI credits, but the overall structure gives teams a generous free plan to test intelligent conversations before moving to paid tiers or adding extra capacity.

Standout Features & Unique Capabilities of Chatling#

• Auto-sync supported sources to keep the chatbot aligned with updated content.
• Use multiple AI models within a single chatbot builder.
• Extend the setup with add-on options for branding, credits, seats, and custom domains.

Pros#

• The builder is easy to learn, even for teams without technical experience.
• Website and WhatsApp deployment work from the same product, which helps teams cover more than one channel early.
• Multilingual support and a clean interface make day-to-day management easier for mixed-language teams.

Cons#

• Imported content can be inconsistent, especially for structured knowledge.
• Answer coverage can miss details even after the content is uploaded.
• Some upgrades, such as branding removal, sit outside the base plan.

Pricing#

• Free: $0/month
• Standard: $40/month
• Plus: $140/month

4. HubSpot#

HubSpot ties its free chatbot builder to its free CRM, which changes how the bot works in practice. Instead of acting like a separate chatbot app, it can qualify leads, send chats into the CRM, create support tickets, surface knowledge base content, and book appointments from the same system.

Image Source: hubspot.com

If your team already uses HubSpot for forms, pipeline tracking, or customer data, that connection is the main reason to try it.

The tradeoff is that the chatbot lives inside a broader platform. The free plan is real, and HubSpot positions many of its core free CRM tools as free forever, but deeper AI features and more advanced automation are bundled into broader paid hubs rather than a simple chatbot-only product.

Standout Features & Unique Capabilities of HubSpot#

• Use CRM-connected chatflows to qualify leads and route customer interactions.
• Book appointments and create support tickets from the chatbot flow.
• Embed the bot on site pages or external pages with the HubSpot tracking code installed.

Pros#

• Ticketing, knowledge base content, and CRM records work together in a single system, helping teams keep support context in one place.
• The help desk is flexible enough for growing teams that want chat connected to broader service workflows.
• Chatbot actions are more useful when lead data, support history, and contact records already live inside HubSpot.

Cons#

• The free version omits features that many teams will want as usage grows.
• Some users find the product cluttered or overwhelming while they learn the system.
• Smaller businesses can find the paid plans expensive.

Pricing#

• Free: $0/month
• Starter: $10/month
• Professional: $890/month
• Enterprise: $3,600/month

5. Zoho SalesIQ#

Zoho SalesIQ combines live chat, visitor tracking, lead scoring, and chatbot automation in one tool. The product includes a chatbot builder, proactive chat, routing rules, canned replies, business hours, translation, and mobile support.

Image Source: zoho.com

It's broader than a basic chat widget because it also tracks how visitors interact with pages, which pages they view, and when the support team should step in.

For companies already using Zoho, that broader view is the main draw. For everyone else, the product still offers a free plan, plus paid tiers that unlock more features, reports, and control over how chat and bot conversations flow between sales and support.

Standout Features & Unique Capabilities of Zoho SalesIQ#

• Track visitor behavior and score leads before a rep joins the conversation.
• Build bots with pre-built templates and multilingual support.
• Combine chat, routing, and proactive outreach in one dashboard.

Pros#

• Real-time visitor tracking helps teams see who is on the site and when to start a conversation.
• Integration with the wider Zoho stack makes lead and support workflows easier to manage.
• Reporting, queue visibility, and chatbot traffic handling make it useful for active support teams.

Cons#

• Customization can feel limited once teams want a more tailored setup.
• The interface can feel clunky when several chats are open at once.
• Duplicate or excessive notifications can interrupt daily work.

Pricing#

• Free: $0/month per user
• Basic: $10/month per user
• Professional: $17/month per user
• Enterprise: $25/month per user

6. Botpress#

Botpress is built more like an AI agent platform than a plug-and-play chatbot for small businesses. It provides a visual editor, website-embed tools, API access, integrations, and support for multiple AI models from different LLM providers.

Image Source: botpress.com

That mix gives technical teams more control over how AI agents behave, which tools they call, and how they work across multiple channels.

The free entry point offers 1 seat and 100 conversations, which may be enough for individuals or smaller teams.

Standout Features & Unique Capabilities of Botpress#

• Build flows in a visual editor instead of coding everything from scratch.
• Publish bots across web chat and messaging channels like Slack, Telegram, WhatsApp, Teams, and more.
• Botpress supports custom code, APIs, and integrations with external tools and data sources.

Pros#

• The visual editor makes it easier to map flows before adding deeper logic.
• Its newer platform is built around LLM-powered, stateful conversations with knowledge bases and multi-step logic.
• The platform gives teams room to build more tailored AI agents instead of sticking to a narrow website widget.

Cons#

• Some users report bugs or rough edges, especially in more custom builds.
• The product asks for more technical confidence than a simpler no-code chatbot.

Pricing#

• Free: $0/month
• Plus: $150/month
• Team: $750/month
• Enterprise: Custom pricing

7. Tawk.to#

Tawk.to starts from a different place than most AI chatbot tools in this list. Its core offer is a completely free live chat widget with ticketing, a knowledge base, chat pages, and a free CRM.

Image Source: tawk.to

For teams that mainly want a free widget and a way to provide customer support without paying upfront, it's one of the easiest tools to try.

AI is available, but it sits in add-on products rather than the core product. That makes Tawk.to useful for small businesses that want free forever live chat first and can decide later whether to pay for branding removal, AI Assist, or hired agents.

Standout Features & Unique Capabilities of Tawk.to#

• The core platform is free forever for live chat, tickets, CRM, and a knowledge base.
• The widget is customizable with changes to color, position, language, and messages.
• Expand later with add-on options such as branding removal, AI Assist, or hired agents.

Pros#

• The free live chat offer is a major draw for teams that want broad core functionality without monthly spend.
• Chat history, visitor monitoring, and basic reporting help teams stay on top of live conversations.
• Handling several conversations at once feels organized for day-to-day support use.

Cons#

• The dashboard can feel cluttered when chat volume picks up.
• Customization is not deep enough for every brand or workflow.
• Some users report slow loading, cache issues, or inconsistent notifications.

Pricing#

• Free

8. Chatbase#

Chatbase focuses on quick training and fast deployment. You can create a bot from website content, sitemaps, text, Notion pages, support tickets, and file uploads, then deploy it to a site in minutes.

Image Source: chatbase.co

The widget can also render forms, buttons, cards, and tables, which makes it more flexible than a plain text chat box when you want to guide visitors through the next step.

The product is easy to test with a free plan, and it can auto-retrain every 24 hours. Higher plans add API access and more usage capacity.

That makes Chatbase useful for teams that want fast setup, simple training on their own content, and a route toward more features without moving into a developer-heavy stack right away.

Standout Features & Unique Capabilities of Chatbase#

• Train from website pages, support tickets, text, files, and connected sources.
• Refresh chatbot knowledge automatically every 24 hours.
• Use richer widget elements such as forms, buttons, cards, and tables.

Pros#

• Bot customization is easy to manage without a steep learning curve.
• Integrations help teams extend the chatbot beyond a basic website embed.
• Automation features help teams handle routine conversations with less manual work.

Cons#

• Customization still has limits once teams want deeper control.
• Pricing becomes harder to justify as usage grows.
• Some users mention dashboard issues and a product that still feels like it's evolving quickly.

Pricing#

• Free: $0/month
• Hobby: $40/month
• Standard: $150/month
• Pro: $500/month
• Enterprise: Custom pricing

How to Choose the Right AI Chatbot for Your Website#

The ideal chatbot should solve your current need without boxing you into a weak upgrade path later.

A free plan can look generous at first, but the real value comes from what the bot can do, how easy it is to launch, and which limits show up once traffic starts coming in.

Check these five things before you choose:

• Free plan structure: Some tools are completely free or free forever, while others only give you a free version with limited features and push the useful AI tools into a paid plan. If affordable pricing matters, check the upgrade path before customer interactions start piling up.
• Training quality: A useful chatbot should learn from website pages, FAQs, uploaded files, or a knowledge base built from your own content. Better training leads to more accurate replies, stronger natural language understanding, and fewer weak answers.
• Setup and deployment: A free website chatbot should be easy to add with a short code snippet and no heavy rebuild. It should also work across multiple platforms, including common CMS tools and e-commerce platforms.
• Handoff and workflow support: Some teams only need a live chat widget. Others need lead capture, live-agent routing, a shared inbox, or a chatbot app to guide visitors, book appointments, or automate follow-up tasks.
• Control and scale: If the bot handles customer data or support requests, check the admin controls, source grounding, and data security options. It's also worth checking what happens when you need more features, more volume, or broader support later.

Turn Your Website Into a 24/7 Support Channel for Free#

A free chatbot for website pages should do more than just greet users and point them to a single FAQ. It should answer questions from real content, support customer experience, capture intent, and give you a clean way to grow once the free plan is no longer enough.

That's the gap Denser is built to cover.

With Denser, you can start free, train the bot on website content or file uploads, preview cited answers, and launch a live chat experience without coding.

From there, you can add lead capture, connect workflows through API access or database tools, and support more user queries without losing control over what the bot is pulling from.

It gives you a practical path from quick setup to a more capable AI chatbot for lead generation, website support, and knowledge access.

FAQs About Free Chatbots for Websites#

Is there a truly free chatbot for websites?#

Yes, some tools offer a truly free chatbot for websites, but the free version often comes with clear limits. Denser offers a free plan that lets you train the chatbot on your own website content and test how it answers real visitor questions on a live site.

How do I add a chatbot to my website for free?#

With Denser, you can add a chatbot to your website for free by creating an account, training the bot on your site content or files, copying the embed code, and pasting it into your site.

What is the difference between free forever and free trial chatbot plans?#

A free forever plan gives ongoing access to a limited set of features at $0 per month. A free trial gives you temporary access to more features for a short period, then prompts you to move to a paid plan or revert to a smaller free version once the trial ends.
