AI chatbots have gone from gimmick to game-changer in 2025. Instead of clunky scripts and generic responses, today’s top tools deliver human-like support, convert more visitors, and provide real-time answers — all without the wait or overhead of live agents.

Whether you're running an e-commerce store, SaaS platform, or content site, modern AI chatbots can make your website feel like a personalized, always-on assistant.

In this guide, we compare the 6 best AI chatbots for websites in 2025 — covering features, pricing, pros, and best use cases — so you can choose the right solution for your goals.

Why You Need an AI Chatbot on Your Website in 2025

Website visitors today don’t want to dig through menus or wait for a live chat agent. They’ve gotten used to something faster, more direct — and more helpful.

, users are becoming conditioned to getting 

 to complex questions. They expect websites to work the same way: no searching, no forms, no hold music. Just clear, useful information delivered on demand.

That shift in user behavior has created a huge opportunity for brands. The right AI chatbot can:

 by helping visitors find the right product or service faster

 in real time, using your own content and data

 and guide users through your funnel 24/7

And unlike traditional live chat or scripted bots, 

modern AI chatbots are powered by large language models

 that can understand nuance, follow context, and deliver natural, helpful replies — even when the question is messy or unstructured.

If you want your website to meet modern expectations and compete with brands already using AI to boost engagement, it’s time to get serious about your chatbot strategy.

Before AI chatbots, you had two choices for helping users get the right information on your website:

You’ve definitely seen these pop up when you visit a website. They ask you to click through pre-made questions and answers that are often incorrect, lack context, and are just trying to collect information from you, not solve your problem. Most sites try to disguise these chatbot pop-ups as human-written messages or AI, but they’re neither.

Visitor satisfaction rates are low with pre-made chatbot interactions, and conversions to revenue-driving actions are also low.

The second option, which you get to eventually through pre-made questions, is to get connected with a human support or sales agent.

Delays are too long for visitors, who want to ask questions right away but have to wait for a human to connect, which most often takes some time.

It’s too expensive for corporations to have enough human agents to be available to answer visitors’ questions in real-time.

Because of ChatGPT and its competitors (Claude, Grok, Gemini, etc.), there will be a new option in 2025: AI-native chatbots.

And thanks to modern software, your website can also offer a ChatGPT-like experience by integrating with one of the vendors below.

These aren’t just upgraded live chats — they’re intelligent agents built from the ground up to understand your content, personalize responses, and guide visitors toward action in real time. No scripts, no delays, no handoffs — just instant, high-quality help that feels natural, not robotic.

Here are the six best AI chatbots for websites in 2025 (more details below) ⤵️

 Best for high-quality AI agents across any industry, plus the only option to offer AI content marketing tools

Best for AI agents with lots of integrations

Best for off-the-shelf AI customer support

Best for combining AI with automation for customer support

Best for customer support for large-scale organizations

 Best for advanced users wanting a visual workflow builder

They all have different approaches and styles. For example, Big Sur AI is built to work out-of-the-box on your site, Intercom has a more traditional chatbot approach, and Botpress is a “build it yourself” option.

Below, we compare them in detail (capabilities, strengths, weaknesses, price, best use cases) so that you can pick the best one for your website.

Octane’s pricing is pretty straightforward but can sneak up on you as you scale your e-commerce business.

This guide aims to clarify what’s included with each of Octane AI’s plans, how the cost will scale over time, potential surprises in the future, and more.

If you find Octane’s pricing too limiting, especially at high volumes, or need more than quizzes to help your brand grow, we’ll suggest modern 

Octane AI pricing increases with quiz engagement volume — not completions. You pay whether users finish the quiz or not.

Octane’s pricing strategy is based on two factors:

. For example, with the business plan, you can remove Octane’s logo from your quizzes or send Klaviyo emails to your responders.

 It starts at $500/month for 4,500 engagements, including all Plus features, a dedicated account manager, managed services, and custom enterprise solutions.

: Octane counts engagements, not completions. This means that each time someone interacts with a quiz, it counts as an engagement, whether they convert or not. Therefore, you can max out your engagements by having 200 people answer one question and leave your site, without buying anything.

Starting price → $50 USD per month for 200 monthly engagements.

Given that you do not need or use premium features (removing watermarks, email automation, etc.), Octane will cost more as you get more quix engagements. Example: $200 per month for 1,500 engagements. ⤵️

The plan is built for smaller businesses or early-stage stores that want to begin collecting zero-party data and personalizing customer experiences.

✖️ Limited to number of engagements per pricing tier (e.g., 1,500/month for $200) 

✖️ AI tools like Smart Copy cost extra 

Starting at $500 USD per month for 4,500 monthly engagements.

Pricing scales significantly based on engagement volume and any added custom solutions.

Octane’s public pricing only details costs up to 200,000 monthly engagements. Companies exceeding this limit will have to discuss their projected engagement volumes with their Octane AI account manager to get a custom price.

The Enterprise plan is designed for high-growth brands and larger teams that need premium support, customization, and the flexibility to run large-scale zero-party data strategies. It includes:

 Including advanced logic branching, custom CSS, pop-up targeting, A/B testing, and Klaviyo dynamic blocks.

 Get hands-on guidance, onboarding support, and strategy recommendations from a named Octane AI expert.

 Tailored quiz experiences, advanced integrations, and unique workflows developed for your store’s specific needs.

✖️ AI tools like Smart Copy and Insights Analyst are not included by default

✖️ Custom solutions may come with added setup costs

✖️ High-volume pricing is opaque (unknown above 200,000 engagements)

Reaching Octane’s plan limits automatically upgrades your plan and unlocks new capabilities.

For example, as you reach past 1,500 engagements per month, you’ll unlock the ability to set conditional branching quiz logic, sync quiz engagement data to Google Analytics, and all other features under the “Plus” plan.

Not forcing double price bumps for other plans’ features is a plus, but it comes at a downside for brands with smaller volumes 👇

If you reverse this, you’ll notice that 

brands with fewer than 1,500 quiz engagements must upgrade to Octane Plus if they want premium features

Octane AI Pricing: Is It Worth It? [2025 Review]

Instead of typing short keywords into Google, customers now ask long, nuanced questions in tools like ChatGPT. Unlike traditional search engines, AI search engines don’t just list links — they summarize and recommend.

That means your product page, blog post, or landing page isn’t just competing for a blue link. It’s competing to be 

The long-tail, precise answer to complex and contextual queries like:

“What would you recommend as the best road bike for me? I live in Boston, am 6 feet tall, and weigh 205 pounds. I don’t like flashy bikes and need one strong enough to handle gravel roads occasionally. My budget is $5,000, and I prefer all-black bikes.”

“I’m looking for a skin care product for my girlfriend and don’t know what to buy. She likes products from X and has been complaining about itchiness. Recommend what would be best for her”.

So, how do e-commerce brands show up in these new results?

By scaling content around long-tail queries — the kind AI search engines are designed to answer — and doing it faster than the competition.

. In this guide, we cover why AI searches require new types of content for e-commerce brands and how our AI Content Marketer helps bridge the gap for brands.

In traditional SEO, ranking meant picking a high-volume keyword like "best skincare products" and writing an optimized blog post or product page.

"What are the best skincare products for sensitive skin and high humidity?"

"Which running shoes are best for people with flat feet and knee pain?"

"I need a cold brew maker that fits in a mini fridge — any recommendations?"

 — specific, intent-rich questions that usually mean a user is close to making a decision.

The problem? You can’t manually write a landing page for every variation of every product use case.

Especially when long-tail queries are transitioning from

“How to make dog food for a 10-year-old 35-pound labradoodle that likes chicken”

The Problem With Traditional Content at Scale

Long-tail content works. But scaling it the old way? Painful.

Here’s why most e-commerce teams struggle:

: Most brands have hundreds (or thousands) of products. You can’t write a blog post for each one manually.

: What customers search for today isn’t always what they search for next month.

: Between product launches, email flows, and ads, long-form SEO content often falls to the bottom of the priority list.

 Until now, mass-producing quality content required large teams or a lot of agency or contractors, which aren’t cheap.

Until now, most e-commerce brand managers were reluctant to leverage AI workflows across all operations (as seen in the table below).

But things are changing fast. This leaves a gap — one that your competitors might already be filling.

Introducing the AI Content Marketer: Your 24/7 Landing Page Generator

It helps e-commerce brands generate long-tail landing pages at scale using their existing product data, with content optimized for both human readers and AI search engines.

It pulls in data like product names, images, descriptions, specs, customer reviews, and FAQs from platforms like Shopify, WooCommerce, or BigCommerce.

No need to manually copy and paste product info.

The system looks at real customer questions and searches, then auto-generates page content to answer those queries.

"Best gift ideas for new dads who love coffee"

"Sustainable activewear for plus-size runners"

Each landing page is built to match the tone and structure that AI search engines tend to use when surfacing results.

Headings and structure optimized for Google indexing

Natural language copy designed to feed LLMs (Large Language Models)

Semantic variations to capture multiple query intents

Want to tweak a headline? Reword a paragraph? Add a seasonal message?

The AI Content Marketer lets your team edit pages conversationally — just chat with the tool and ask it to revise the content.

💡 This is a massive improvement from traditional landing page builders like Unbounce, PageFly, and Shogun, who all require manual drag-and-drop edits (which take much longer).

5. Can create landing pages from custom prompts

If you need a specific page or a cluster of pages around a topic created, you simply have to type in your request, and Big Sur AI will generate the right landing pages.

This is a feature that none of the other competing AI landing page builders have, especially considering that Big Sur AI has direct access to your store’s data, and won’t make false claims or make up information.

How It Works (From a technical standpoint)

 (via Shopify, BigCommerce, WooCommerce, or API)

 — e.g., "Generate a page for every product with 3+ reviews," or "Create landing pages based on top customer questions."

 — It pulls content, understands themes, and builds structured, optimized landing pages.

 — Your team can review and revise using the chat-based editor.

 — Pages go live and begin ranking for long-tail queries across both AI and traditional searches.

Big Sur AI offers two flexible pricing models (

Pay only when the AI Sales Agent drives a sale.

This performance-based model charges a commission for conversions directly attributed to Big Sur AI. The attribution window is typically 30 days, but can be customized based on your needs.

Pay a flat monthly rate based on your site’s average monthly unique visitors.

This model is best for brands with steady traffic who prefer predictable costs.

You can pay a commission on closed deals or a fixed salary based on store traffic—whichever best suits your business.

In the past, SEO was about competing for 10 keywords.

With AI search engines pulling answers from a mix of structured data, semantic content, and context, your brand needs pages built to feed that ecosystem.

Big Sur AI gives you the engine to do just that, and other AI-powered features to drive more conversions on your store.
