How did we compare website AI chatbots?
We looked at each tool from the point of view of a small or mid-size business owner adding a chatbot to an existing website, often without a developer. Every price was checked on the vendor's own pricing page in October 2026. Where a vendor does not publish a number, we describe the pricing model.
- Setup effort. Can you paste a snippet or install a plugin, point the bot at your site and go live without writing code?
- Answer quality. Does it answer from your own content, and can you control what it says?
- Lead capture. Can it collect contact details, qualify a visitor or book a meeting?
- Support depth. Can it hand off to a person with context, and can it take actions such as looking up an order?
- Pricing model. Per resolution, per message credit, per conversation or per seat, and what happens when traffic spikes.
- Room to grow. Does it add email, WhatsApp and a shared inbox later, or will you outgrow it?
This list is about chatbots on your own website. If you are choosing AI for a whole support operation across channels, read our customer service chatbot comparison instead.
We are Aftersales, so we put our product first. Each card says where another tool is the better choice, including against us.
What are the 9 best AI chatbots for websites?
Each card lists the pricing unit, because that decides your monthly bill more than the headline price.
1. Aftersales: best for websites where the chatbot needs to resolve support requests
Aftersales puts an AI Agent behind your website chat that resolves conversations end to end. It reads intent, sentiment and language from the first message in 31 languages, answers from one knowledge source shared with your help center, and follows procedures you write in plain language. Where a visitor needs something done, it can verify and act on Shopify orders, issue Stripe refunds or update Salesforce, within spend limits you set.
When Agent can't finish, it hands off to a person in the shared Inbox with the conversation, the data it looked up and what it already tried. The Free plan covers one seat, live chat, an email inbox, a public help center and your first 50 Agent resolutions, so a small business can test it without paying. Customers see a median 71% of conversations resolved by Agent after 90 days.
- Best for
- Small and mid-size businesses whose website chat is mostly support: orders, bookings, accounts, refunds
- Pricing
- Free $0 (1 seat). Starter $24, Growth $69, Scale $109 per seat/month billed annually (20% more monthly). Agent $0.99 per resolution, counted once per conversation; conversations Agent can't help with are free
- Strengths
- Resolves and takes actions instead of only answering; one inbox later covers email, WhatsApp, SMS, social and phone; escalation rules on sentiment, keywords and legal language; GDPR DPA and US-hosted data
- Watch out for
- Built for support, not marketing. It has no lead-scoring or meeting-booking bot, so pure lead-generation sites are better served by HubSpot or Landbot. A younger company (founded in London in 2024); confirm niche integrations on a call
Try it on your own website traffic.Start free, and pay $0.99 only when Agent resolves a conversation.
2. Chatbase: best for a quick FAQ bot trained on your site
Chatbase lets you build an AI agent from your website, documents and other sources and embed it on your site without code. Paid plans add actions, integrations such as Stripe, Zendesk, Shopify, HubSpot and Calendly, and, from Standard up, a helpdesk, voice and API access.
It is one of the fastest ways to get a knowledgeable bot live. Billing is by message credits, so a long conversation costs more than a short one.
- Best for
- Owners who want an AI answer bot on the site this week, with minimal setup
- Pricing
- Free $0 (50 message credits/month; agents deleted after 14 days of inactivity). Hobby $40, Standard $150, Pro $500 per month (20% off yearly). Extra credits $40 per 1,000; removing Chatbase branding is a $99/month add-on
- Strengths
- Very quick setup; choice of AI models; wide integration list; GDPR DPA and US-hosted data
- Watch out for
- Credits scale with messages, not outcomes; human handoff and a full inbox need higher plans or another tool
3. Tidio: best for small online stores that want chat, AI and Flows together
Tidio combines live chat, ticketing, its Lyro AI Agent and Flows, which are no-code automations for lead capture and sales prompts. It is popular with small ecommerce stores and is easy to install on common site builders.
Lyro is priced separately from the helpdesk, so check both numbers.
- Best for
- Small stores that want one widget for chat, AI answers and pop-up Flows
- Pricing
- Free plan. Starter $24.17/month billed annually (100 billable conversations, 50 one-off Lyro conversations). Growth from $49.17/month. Plus from $300/month plus usage. Lyro on its own from $32.50/month for 50 AI conversations
- Strengths
- Simple setup, Flows for lead capture, Lyro can also run inside other helpdesks
- Watch out for
- Separate meters for human conversations, Lyro conversations and Flows visitors make costs harder to predict as you grow

4. Crisp: best for a flat workspace price with a shared inbox
Crisp offers a website chat widget, shared inbox, CRM, knowledge base and its Hugo AI agent. Plans are priced per workspace with a set number of seats included, which suits small teams that do not want per-seat billing.
- Best for
- Small teams that want predictable monthly pricing with several seats
- Pricing
- Free (2 seats, website chat, no AI credits). Mini $45, Essentials $95, Plus $295 per workspace/month. AI credits included: $5 on Mini (around 90 automated conversations), $25 on Essentials, $75 on Plus
- Strengths
- Seats bundled into the plan; WhatsApp, Instagram and SMS from Essentials; ecommerce plugins for Shopify and WooCommerce
- Watch out for
- AI volume on lower plans is small; heavy AI use means moving up a tier
See Crisp alternatives.
5. tawk.to: best for free live chat on a tight budget
tawk.to is free live chat software for websites, with a ticketing inbox, CRM and knowledge base. Its AI Assist add-on answers chats from your knowledge base and FAQs around the clock.
- Best for
- Very small businesses that want live chat at no cost and can add AI later
- Pricing
- Live chat free. AI Assist from $29/month. Removing tawk.to branding costs $29/month

See tawk.to alternatives.
6. HubSpot: best for capturing leads into a CRM
HubSpot's free chatbot builder creates rule-based bots that qualify leads, book meetings, answer common questions and hand off to a live agent, with replies personalized from HubSpot CRM data. Its AI customer agent, which answers from your knowledge base and website, is a separate product for Professional and Enterprise customers.
- Best for
- Businesses already on HubSpot that want website chat to feed the sales pipeline
- Pricing
- Chatbot builder free. AI customer agent requires a Professional or Enterprise edition and runs on HubSpot Credits: $0.50 per resolution for messaging
- Strengths
- Leads land in the CRM with full context; meeting booking; email campaigns triggered after a chat
- Watch out for
- The free bot is rule-based, not AI; the AI agent needs a paid Professional or Enterprise subscription first
See HubSpot Service Hub alternatives.
7. Landbot: best for guided lead-generation flows and WhatsApp
Landbot is a no-code builder for website and WhatsApp chatbots, with AI agents and a visual flow builder. It leans toward marketing and sales: qualifying visitors, collecting details and pushing them into tools such as HubSpot and Airtable.
- Best for
- Marketing teams that want structured, conversational lead forms
- Pricing
- Free €0 (100 chats/month, no AI chats). Starter €32/month billed annually (€40 monthly) with 500 chats and 100 AI chats. Professional €80/month billed annually with 2,500 chats and 300 AI chats. Extra AI chats €0.10. Business from €400/month
- Strengths
- Visual builder with templates and A/B tests; WhatsApp add-on; published overage prices
- Watch out for
- Priced in euros; not a support helpdesk, so complex service conversations need another tool
8. Botpress: best for custom bots built by a technical team
Botpress is a platform for building AI agents, with a visual studio, knowledge bases, tables and integrations across channels. It gives the most control on this list, and it rewards teams that can spend time designing the bot.
- Best for
- Teams with a developer or agency that want a tailored bot
- Pricing
- Free $0 (100 conversations/month, 3 seats). Plus $150/month billed annually (250 conversations, packs of 100 for $65). Team $750/month billed annually (1,500 conversations)
- Strengths
- Deep customization; AI usage included in plans; works across many channels
- Watch out for
- More setup than plug-and-play tools; overkill if you only need FAQs answered
9. SiteGPT: best for a single knowledge bot on a content-heavy site
SiteGPT trains a chatbot on your website content and files, answers visitors around the clock, collects leads and lets visitors escalate to a live agent. Each plan caps the number of chatbots and pages it can learn from.
- Best for
- Sites with large documentation or content libraries
- Pricing
- Starter $39/month billed yearly ($59 monthly): 1 chatbot, up to 4,000 messages, 1,000 pages. Growth $79/month yearly ($129 monthly). Scale $259/month yearly ($429 monthly). 7-day trial, card required
- Strengths
- Learns from up to 500,000 pages on Scale; weekly email digest of unanswered questions; lead collection
- Watch out for
- No free plan; branding removal and extra messages are paid add-ons; handoff relies on a separate live-chat tool
Which website chatbot should you choose?
Choose by what most of your website conversations are about.
- Support requests that need an action (order status, refunds, bookings, account changes): Aftersales.
- An AI FAQ bot live today with almost no setup: Chatbase or SiteGPT.
- Lead capture into a CRM and meeting booking: HubSpot. Aftersales is not built for this.
- Conversational lead forms and WhatsApp campaigns: Landbot.
- Free live chat first, AI later: tawk.to, or the Aftersales Free plan if you want AI resolutions included.
- Small online store wanting chat, AI and pop-ups in one widget: Tidio.
- Flat pricing with several seats included: Crisp.
- A custom bot built by a developer: Botpress.
How much does an AI chatbot for a website cost?
Per-resolution pricing tracks results; credit and conversation pricing tracks traffic. Here is one example using list prices.
Example assumptions: a services business gets 600 website chats a month, has 2 people answering, and Agent resolves 50% of chats (below the 71% median, to be cautious).
- Aftersales Starter: 2 seats × $24 = $48 per month, billed annually.
- Agent: 300 resolutions × $0.99 = $297 per month. The other 300 chats go to your team and cost nothing extra.
- Total: about $345 per month, or roughly $0.58 per website chat.
If your volume is low, start on the Free plan: the first 50 resolutions are free. See pricing and our guide to measuring resolution rate.
