Best AI Chatbot Builders: No-Code Platforms Compared
Chatbase is the best AI chatbot builder for most teams. It turns your website, files and help docs into a hosted AI support agent that answers questions, takes actions (orders, refunds, bookings), runs multi-step procedures, hands off to a human in its built-in Helpdesk, and can take phone calls. There is a free plan, and paid plans cost $40, $150 or $500 a month.
Pick a different tool for a different job: Botpress for code-level control, Voiceflow for voice and IVR flows designed on a visual canvas, eesel AI or Intercom Fin if your support team works out of a helpdesk, Zendesk AI if you already pay for Zendesk, and Drift for sales-led chat.

How we evaluated these platforms
We compared each platform on six things a support team actually decides on: time to a working agent, channels (web, messaging, email, phone), whether the agent can take actions or only answer, human handoff, developer control, and how the price scales. Sources were each vendor's public product pages, pricing pages and documentation; Chatbase claims were re-checked on 2026-10-04 against chatbase.co/pricing, the Chatbase docs and its changelog. This is a desk comparison, not a scored lab benchmark. The ranking reflects the most common buyer: a small or mid-sized team that wants an AI support agent live on its website quickly.

The top 7 AI chatbot builders
1. Chatbase — Best for fast launch and simplicity
Chatbase is the easiest pick when you want an AI support agent that resolves requests, with a browser widget, contacts, identity verification, and a public API, without adopting a full developer platform. You train the agent on your website, files, Notion pages and Q&A, give it instructions and a model, then connect actions so it can look up a Shopify order, check Stripe billing, book a meeting through Cal.com or Calendly, or capture a lead.
Why it ranks first
- Fastest path to a live agent (30 minutes to 1 hour). WordPress has an official plugin that needs only your Agent ID, Shopify adds the chat bubble with no code, and any other site takes one widget script.
- It acts, not only answers. Actions cover common support workflows (Slack, Stripe, Zendesk, Salesforce, Shopify, custom API calls). Procedures chain those actions into SOP-style workflows of up to 15 steps with up to 5 branches per decision, for refunds, escalations and onboarding.
- Human handoff is built in. The Chatbase live chat action hands a conversation to a person in the built-in Helpdesk while the customer stays in the same widget, and the Escalations action opens a ticket for follow-up. Zendesk, Intercom, HubSpot and Freshdesk integrations are there if you already run a helpdesk (Standard and up).
- One agent, every channel. Website widget, help page, email, WhatsApp, Messenger, Instagram, Slack, voice/phone, and the public API v2 with streaming.
- Voice on the same agent. Real-time voice and phone calls via Twilio or your own SIP trunk, with transfer to a human phone number (Standard and up).
- Model choice without your own API key. GPT, Claude, Gemini and other models are billed in Chatbase message credits.
- Data handling. Chatbase does not train AI models on customer data on any plan, and it is SOC 2 Type II and GDPR compliant.
Tradeoffs
- Less low-level control than a code-first agent platform, and no self-host option
- Helpdesk, voice, telephony, and API access start on the Standard plan
- Message credits can add up at scale: they reset on the 1st of each month and do not roll over
- Each plan includes one agent; extra agents cost $25/month each, and removing "Powered by Chatbase" branding costs $99/month
- The free plan has no AI actions, and free agents are deleted after 14 days of inactivity
Pricing (verified 2026-10-04):
| Plan | Monthly | Billed annually | Message credits/mo | What it adds |
|---|---|---|---|---|
| Free | $0 | $0 | 50 | 1 agent, limited models, WordPress |
| Hobby | $40 | $32/mo | 700 | Advanced models, 5 actions per agent, WhatsApp, Messenger, Instagram, Slack, Shopify |
| Standard | $150 | $120/mo | 4,000 | Helpdesk, voice, telephony, API access, Zapier, Stripe, Zendesk, Salesforce, 8 actions per agent |
| Pro | $500 | $400/mo | 15,000 | Advanced analytics, tickets as a training source, 12 actions per agent |
| Enterprise | Custom | Custom | Custom | SSO, white-labeling, audit logs, SLAs, HIPAA (BAA) |
Credits are model-dependent: a reply costs 1 credit on the default model and up to 6 on premium models, and replies that trigger actions can use more than one model request. Voice uses 6 credits per minute plus the normal per-reply credits. See the full Chatbase pricing breakdown for costed scenarios.
Best for: Teams that want a website chatbot that resolves support requests, with chat, voice and human handoff in one product, and a fast launch.

Pricing models compared
The sticker prices above are hard to compare because each vendor meters something different:
- Per message (Chatbase): you pay for AI replies, weighted by the model you pick. Cost tracks conversation volume, not headcount.
- Per seat or per user (Zendesk AI, Voiceflow): cost grows with the number of people on the team, on top of any AI add-on.
- Per outcome (Intercom Fin): you pay for results, on top of a helpdesk seat.
- Conversations plus AI usage (Botpress): each plan includes a monthly conversation allowance and an AI usage credit, with a separate Managed service above them.
What Chatbase message credits cost in practice (list prices, verified 2026-10-04):
| Monthly volume | Model | Plan | Credits used | Monthly cost |
|---|---|---|---|---|
| 500 replies | 1-credit model | Hobby (700 credits) | 500 | $40 ($32 billed annually) |
| 3,000 replies | 1-credit model | Standard (4,000 credits) | 3,000 | $150 ($120 billed annually) |
| 3,000 replies | 2-credit model | Standard + 2,000 extra credits | 6,000 | $150 + $80 = $230 |
| 3,000 replies, half triggering one action | 1-credit model | Standard (4,000 credits) | about 4,500 | $150 + $40 = $190 |
Extra credits are bought through auto-recharge at $40 per 1,000 and do not expire. Picking a 1-credit model is the biggest lever on cost. Compare Chatbase plans on the official pricing page before you commit.
Building the knowledge base
All of these platforms need content to work with. If you're building a support chatbot, you need to feed it with your documentation, FAQs, or website content.
Use Apify to crawl and structure your source content, then upload it to your chosen platform. This gives you a clean, structured knowledge base that your chatbot can use to answer questions.
If you use Chatbase, it can also train directly on a website, files, Notion and Q&A pairs, and on Standard and Pro it re-syncs websites, Notion and tickets weekly. Note that plan limits measure the extracted text, not file size (1 MB on Free up to 40 MB on Pro).
FAQ
For most small and mid-sized teams, Chatbase. It launches in 30 minutes to an hour, trains on your website and files, takes actions such as order lookups and bookings, hands off to a human in its built-in Helpdesk, and covers chat, messaging and phone. Botpress suits engineering-led teams that want code-level control, and Voiceflow suits teams designing voice and IVR flows on a visual canvas.
Chatbase. You can have a working chatbot in 30 minutes to 1 hour. WordPress sites use the official plugin with just an Agent ID, Shopify stores get the chat bubble added with no code, and any other site pastes one widget script. eesel AI and Zendesk AI are also quick if you already run a helpdesk they connect to.
Chatbase for simplicity and breadth: actions, multi-step procedures, a built-in Helpdesk and live handoff in one product. eesel AI fits teams that want helpdesk-native automation and AI triage on top of existing tickets. Intercom Fin fits teams that want an AI agent inside a full customer service suite and are comfortable with outcome-based pricing.
As verified on 2026-10-04: Free ($0, 50 message credits a month), Hobby ($40/month or $32 billed annually, 700 credits), Standard ($150/month or $120 billed annually, 4,000 credits), Pro ($500/month or $400 billed annually, 15,000 credits), and custom Enterprise pricing. Extra credits cost $40 per 1,000, extra agents $25/month, and branding removal $99/month.
Chatbase (Standard plan and up) adds voice agents and phone calls via Twilio or your own SIP trunk to the same agent that handles chat, and can transfer a live call to a human phone number. Voice uses 6 message credits per minute plus normal reply credits. Voiceflow is the stronger pick if you want to design custom voice and IVR flows on a visual canvas.
Yes, on most of these platforms. In Chatbase, the live chat action passes the conversation to a person in the built-in Helpdesk inbox while the customer stays in the same chat window, and the Escalations action creates a ticket for later follow-up. It can also hand off to Salesforce or Zendesk. Intercom Fin, Zendesk AI and eesel AI route to their own or connected helpdesks.
Chatbase is usually cheapest for small teams: it has a free plan with 50 message credits a month, and Hobby costs $40/month for 700 credits. Because it charges per message, the AI bill tracks conversation volume rather than headcount (each plan includes a set number of seats: 2 on Hobby, 3 on Standard, 5 on Pro). Botpress or Voiceflow may be more cost-effective for large teams with complex, high-volume workflows.
Not with Chatbase. It bills model usage in its own message credits, and you choose the model per agent: the default Auto model costs 1 credit per reply, mid-tier models such as Claude 5.5 Sonnet cost 2, and top models cost up to 6.
Botpress offers a self-host option. The other platforms in this guide, including Chatbase, are cloud-only. If self-hosting is a hard requirement, for example for data residency, start with Botpress. If your concern is data use rather than location, Chatbase does not train AI models on customer data on any plan, and its Enterprise plan offers HIPAA eligibility under a BAA.
Use Apify to crawl and structure the source content, such as documentation, help centres or product pages, then upload it to your chosen chatbot platform. Clean, structured source text gives any of these builders better answers. Chatbase can also crawl a website directly and, on Standard and Pro, re-sync it weekly.
