10 Best AI Chatbot Builders of 2026

Botpress covers the whole build cycle in one account. Viber turns a written description into an agent, Studio gives builders a visual canvas with real-time collaboration, and Desk adds a help desk so people can pick up conversations the bot cannot finish. The free plan is generous for testing, with 100 conversations, 3 seats and 3 AI agents. Plus costs $150 per month billed annually and adds unlimited agents, WhatsApp, white-label web chat and a $25 AI usage allowance; Botpress also covers $0.10 of model usage inside every conversation. Pricing is per conversation, not per resolution, which Botpress argues keeps bills predictable. Two caveats stand out. The jump from free to $150 is steep for a hobby project, and once you cross 95 percent of your quota a pack of 100 conversations is added automatically, with no option to pause. Voice is listed only on the Enterprise tier.

Chatbase is built around one idea: point it at your content and get a working agent you can publish anywhere. Even the $32 Hobby plan, billed yearly, connects to WhatsApp, Messenger, Instagram, Slack, Shopify and WordPress, and lets you pick advanced models from OpenAI, Anthropic, Gemini, Mistral and DeepSeek. Each agent can run AI Actions and Procedures, so it can do more than answer from documents. The Basic plan at $120 per month billed yearly is where it becomes a support platform, adding voice, telephony, a helpdesk inbox, API access and connectors for Zendesk, Salesforce, Intercom, HubSpot, Freshdesk and Zapier. Chatbase lists SOC 2 Type II, GDPR and HIPAA coverage. The trade-offs are cost and limits: there is no free plan, every tier includes a single agent, extra agents cost $25 per month, and white-labeling is a $99 monthly add-on.

Dante AI is aimed at owners who want one assistant that handles the website, the phone and incoming leads without stitching tools together. The free plan is permanent and includes 1 agent, 100 messages a month and 10 minutes of voice. Starter at $40 per month, or $33.33 billed yearly, raises that to 2,000 messages and 25 million characters of knowledge, opens every AI model and connects to 9,000+ apps through Zapier. Dante re-syncs website, Google Drive and Notion content on a schedule, weekly on Starter and daily on Pro, so answers stay current. Credits vary by model, so heavier models give fewer answers per plan. The main limitation is where features sit: leads, the human takeover inbox, branding removal and a phone number all start on the $120 Advanced plan, and the API requires the $400 Pro plan. For a single site that mostly needs answers, Starter is fair value.

ManyChat solves a narrower problem than the general builders here, and solves it well: turning social engagement into automated conversations. It connects to Instagram, Messenger, TikTok, WhatsApp, Telegram, SMS and email, and its builder handles comment replies, follow-to-DM flows and lead capture. Pricing counts active contacts, meaning each person you interact with in a month, regardless of message volume. The free plan covers 25 contacts and 2 channels; Essential costs $14 per month billed annually for 250 contacts with unlimited automations and no ManyChat branding. AI-powered conversations arrive with Manychat AI on the $29 Pro plan, which also raises the limit to 2,500 contacts and 3 channels. Overages are charged per extra contact rather than shutting automations off. Keep in mind that prices shown exclude tax and depend on billing country, and that ManyChat is not designed for help desk or website support bots.

Landbot has been a visual chatbot builder for more than ten years and now adds AI agents on top of its flow builder. The focus is conversion: lead capture, qualification and routing on websites and WhatsApp. The free plan includes 100 chats a month and the full builder but no AI chats. Starter adds 500 chats, 100 AI chats and 2 seats, and Professional raises that to 2,500 chats and 300 AI chats, removes Landbot branding and unlocks HubSpot, Salesforce, Pipedrive, webhooks and the API. WhatsApp with your own number is an add-on on Professional. Overage prices for extra chats and AI chats are published, and Landbot alerts you at 80 and 90 percent of quota. Newer additions include an MCP server and a way to build Landbot agents from inside Claude. Landbot's pricing page served euro prices to us, so we have left the USD price pending.

Chatfuel is built for businesses whose customers write on WhatsApp, Instagram, Facebook and TikTok. Its AI agent replies to comments and DMs, answers questions about hours, prices and delivery, qualifies leads from click-to-chat ads and books meetings in WhatsApp. Business S costs $18 per month billed yearly and includes $20 of AI credits each month. The pricing page includes a calculator that estimates usage from the kind of bot, the channels and the answer quality you choose, and it shows unit costs such as about $0.0093 per AI reply and $0.020 per Meta Conversions API event. That level of cost detail is rare in this category. The limits are worth noting: there is no free plan, AI replies pause if credits run out, and messages you start on WhatsApp are template messages billed at Meta's rate plus 10 percent. Agencies can manage 3 companies on Agency S at $90 per month billed yearly.

SiteGPT does one job: answer visitors from your own website content. You point it at your pages and files, and each plan sets clear limits, from 1,000 pages and 4,000 GPT-4.1-mini messages on Starter to 50,000 pages and 40,000 messages on Scale. Starter costs $39 per month billed yearly or $59 monthly. The Growth plan at $79 per month billed yearly is where it gains reach: 2 chatbots, 4 members, API access, monthly auto refresh and connectors for Slack, Messenger, Google Chat, Crisp, Freshdesk Messaging and Zoho SalesIQ. Growth also adds an iOS app so a person can take over from the AI on a phone, plus a weekly digest of questions the bot could not answer. SiteGPT supports 95+ languages and states SOC 2 Type II compliance. Starter is thin for teams, with 1 member and manual refresh only, and every trial needs a card.

Typebot is the open-source option in this list. It is a visual builder for chat forms and conversational flows, with 20+ blocks such as text fields, buttons, date pickers and payment inputs, and integrations with OpenAI, Google Sheets, Zapier, Make and plain HTTP requests. You can embed a bot as a container, popup or bubble on WordPress, Shopify, Webflow, Framer or a React app. The hosted free plan gives unlimited bots and 200 chats a month, and a chat counts once per user session however many messages are sent. Starter costs $39 per month for 2 seats and 2,000 chats, and removes branding; Pro at $89 adds WhatsApp, custom domains and deeper analytics. Typebot only bills monthly because pricing follows usage. It fits lead capture and guided flows better than document-trained support agents, which you would have to assemble yourself with the OpenAI block.

CustomGPT.ai targets organizations that care most about answering correctly from a lot of material. Even the $99 Standard plan includes 10 agents, 5,000 documents per agent, 60 million words of storage and access to its RAG API, which is more capacity than any other entry plan here. CustomGPT.ai says it has 100+ integrations for ingesting content from websites and sources such as Shopify, Wix and Notion, and it supports 92 languages. Premium at $499 per month adds 25 agents, 5,000 queries, website auto-sync and removal of CustomGPT.ai branding. Enterprise adds forward-deployed engineers, SSO and custom limits. The weak spot is query volume relative to price: 1,000 queries a month on Standard is modest for a public website bot, and there is no free plan, only a 7-day trial. Yearly billing saves 10 percent.

Voiceflow is the most configurable builder in this list and the least transparent on price. It lets teams combine agentic playbooks, where the model works out how to resolve a task, with deterministic workflows for steps that must happen in a fixed order, all under global instructions and guardrails. Agents can run on web, in apps, on WhatsApp and SMS, and by voice, and you can choose among major LLM providers or bring your own model. A test suite simulates conversations, LLM-powered evaluations score agent performance, and environments separate development, staging and production. Voiceflow lists SOC 2, ISO 27001, GDPR and HIPAA, and says it has 3,000+ customers. The pricing page shows two paths: an agency plan with a free trial and usage-based billing, and a business plan that requires a demo or a pricing request. No dollar figures are published, so we scored value conservatively and left pricing pending.
