11 Best SiteGPT Alternatives in 2026

SiteGPT is a no-code website chatbot builder. You enter a URL, it crawls your website content, you pick the pages to train on, and you embed the widget. It pulls training sources from websites, sitemaps, files, YouTube, GitHub, Notion, Google Drive, and Dropbox, which is a wider range than most AI chatbot platforms. Lead capture is built into the chat flow.

SiteGPT runs on the model you choose, which decides how far your plan goes. The Starter plan advertises up to 4,000 messages a month. That figure is the all-mini ceiling.

Two other details matter. The price shown first is the annual rate: Starter is $39 a month with a yearly commitment and $59 billed monthly. And the Starter plan has no integrations and no API, so it is a website chatbot and nothing else.

If you are looking for an alternative to SiteGPT, this page compares seven of them on pricing, AI model limits, live chat, and free plans.

Quick picks

• Lowest cost per message: Nivon, at about $0.004 on the $12 Starter plan, with no model split.
• Best free plan: Nivon. 150 messages a month, no credit card required, and it does not expire.
• Best built-in live chat: SiteSpeakAI, with a chat inbox included from the free tier.
• Widest integrations: Chatbase, including Zendesk, voice, and telephony.
• Best for documentation: DocsBot, with source citations on every answer.
• Best for helpdesk ticket automation: My AskAI, working inside Zendesk, Intercom, and Freshdesk.

Why teams look for alternatives to SiteGPT

SiteGPT does several things well. Twelve training source types, including GitHub and YouTube, are more than most competitors offer. One message covers a question and its reply, counted together, which is a fairer unit than platforms that count them separately. Annual billing saves up to 40%, the largest discount in this category. Lead capture is prominent rather than buried, which suits marketing sites.

Here is what drives teams to look for a SiteGPT alternative.

The AI model you pick moves your allowance tenfold

SiteGPT's published message limits assume you run GPT-4.1-mini. Switch to GPT-4.1 and the ceiling drops by a factor of ten.

On the Starter plan at $59 a month, billed monthly, 400 messages works out to about $0.15 per AI conversation. The same plan on mini works out to about $0.015. Your bill does not change. Your capacity changes by 10x.

Annual pricing plan gap

SiteGPT shows $39, $79, and $259 first. Those are annual rates. Billed monthly, the same plans cost $59, $129, and $429. The gap is the largest in this category, because the annual discount runs from 34% to 40%.

The starter plan has no integrations

Starter is a chatbot on your website and nothing more. No Slack, no Zendesk, no API access, no webhooks. Integrations begin with Growth at $129/month, billed monthly, and Zendesk AI Agent requires Scale at $429.

No free plan

SiteGPT offers a 7-day free trial and no permanent free tier. Nivon, Chatbase, Chatling, SiteSpeakAI, and DocsBot all offer free plans that never expire.

Auto-refresh is gated by tier

Starter refreshes your knowledge base manually only. Growth adds monthly auto-refresh, Scale adds weekly refresh plus daily sitemap scanning. If your docs change often and you are on Starter, keeping the bot up to date is a manual job.

One chatbot on Starter, three on Scale

Starter allows 1 chatbot, Growth 2, and Scale 3. Running separate bots for support, sales, and internal help means moving up tiers rather than paying a small per-bot add-on.

How to compare these tools

Ask every AI chatbot platform the same questions.

• Does the AI model you choose change how many messages your plan allows?
• Is the advertised price the monthly rate or the annual rate?
• Does the entry plan include integrations and API access, or is it widget-only?
• Is there a free plan, or only a free trial?
• Is live chat with human handoff included, or gated to a higher tier?
• How often does the knowledge base refresh on the plan you are buying?
• How many chatbots does the plan include?

The 7 best SiteGPT alternatives

Nivon AI

Nivon AI is a no-code AI support agent you train on your website content, documents, FAQs, and past support tickets. The agent answers from that knowledge base and, when it cannot, hands the conversation to your team with the full thread attached. Unlike SiteGPT, one credit equals one message on any AI model, so picking a stronger model does not shrink your allowance. Nivon is built by Pimjo, which ran it on its own products for 45 days before release.

Key features:

• Trains on website crawls, sitemaps, uploaded docs, Google Drive, OneDrive, FAQs, pasted text, and past support tickets
• 20+ AI models across OpenAI, Anthropic, Google, and xAI, switchable per agent
• Guardrails defining what the agent handles, refuses, never shares, and escalates
• Human handoff carries the full conversation, so customers never repeat themselves
• Separate workspaces with admin and member roles
• Replies in 95+ languages, with analytics on volume, resolution rate, and response time

Pros:

• About $0.004 per message, against $0.015 on SiteGPT Starter with mini and $0.15 with GPT-4.1
• No model split, so the allowance means the same thing whichever model you run
• Free plan gives 150 messages with no credit card required and no expiry
• Anthropic, Google, and xAI models are available, where SiteGPT runs OpenAI only
• Seats included up to each plan's limit, with no per-seat pricing

Cons:

• Fewer training sources than SiteGPT's twelve. No GitHub, YouTube, or Dropbox
• No lead capture forms are built into the chat flow
• No Zendesk integration. Slack and Telegram are in progress
• SOC 2 Type II is in progress, not complete

Pricing: Free at $0 with 150 credits a month and 1 team member. Starter is $12 a month, or $9 on annual billing, with 3,000 credits and 3 members. Growth is $39 a month, or $29 annually, with 12,000 credits and 5 members. Business is $79 a month, or $59 annually, with 30,000 credits and 15 members.

Best for: Teams that want a predictable allowance and a choice of AI models. If your use case depends on lead-generation forms or training from GitHub, SiteGPT covers both, whereas Nivon does not.

Chatling

Chatling is a no-code AI chatbot builder with a visual workflow builder. You design conversation branches by dragging blocks, or let the AI answer from your knowledge base. It supports 29 AI models across six providers and publishes the exact cost of each model, which is the clearest pricing disclosure here.

Key features:

• Visual drag-and-drop workflow builder for scripted conversation paths
• 29 AI models across OpenAI, Anthropic, Google, Mistral, xAI, and DeepSeek
• Live chat with human handoff and an AI-generated summary for the agent picking up
• AI actions that let the bot complete tasks mid-conversation
• WhatsApp, Instagram, Messenger, and Telegram on paid plans
• Round robin routing on higher tiers

Pros:

• Publishes the credit cost of all 29 AI models, so you can calculate capacity before buying
• Free plan gives 200 AI credits plus unlimited non-AI chats, and does not expire
• Models from Anthropic, Google, Mistral, and xAI, where SiteGPT runs OpenAI only
• Live chat and human handoff are included on paid plans

Cons:

• Credits scale by model, from 0.5 per reply up to 25 on Claude Opus 5
• The $25 Starter plan buys 1,750 credits, which is 70 AI conversations on the most expensive model
• Branding removal costs $35 a month unless you reach the Scale plan
• Fewer training source types than SiteGPT

Pricing: Free at $0 with 200 AI credits. Starter is $25 a month, or $21 annually at $250 a year, with 1,750 credits. Growth is $75 a month, or $63 annually at $750, with 6,000 credits. Scale is $295 per month, or $ 2,950 annually, with 35,000 credits and branding removal included.

Best for: Teams that want scripted conversation flows alongside AI answers, and a vendor that publishes its credit maths.

SiteSpeakAI

SiteSpeakAI is a website chatbot builder with an attached chat inbox. It trains an AI agent on your website content, then pairs it with conversation history, an AI search bar, and page context awareness. It is the closest match to SiteGPT on this page, with live chat as the main difference.

Key features:

• Live chat widget, chat inbox, and conversation history from the free plan
• AI models from OpenAI, Anthropic, Google, and xAI, with Bring Your Own Keys on Pro
• API and MCP Server access on Pro
• WhatsApp, Google Chat, and HubSpot integrations on Pro
• Prompt Guard on every tier, PII redaction on Business
• Agency program with white-label dashboards and client sub-teams

Pros:

• A free plan rather than only a trial, and the inbox is included in it
• Models from four providers, where SiteGPT runs OpenAI only
• Branding removal is included in the Starter plan, where SiteGPT charges $39 a month
• Agency and reseller plans, which SiteGPT does not offer

Cons:

• Escalating to Human Support requires the Pro plan. Free and Starter have the widget without the handoff
• Advanced AI models, API access, and Zapier all begin at Pro
• The free tier includes 30 message credits, enough for a short test only
• Extra message credits cost $25 per 1,000, one of the highest top-up rates here

Pricing: Free at $0 with 30 message credits, 1 AI agent, and 10 training sources. Paid plans start at about $29 a month with 1,000 credits, 1 agent, and 200 training sources. Pro adds 3,000 credits, 5 agents, all models with BYOK, and API access. Growth and Business add 10,000 and 20,000 credits. Annual billing saves up to 17%.

Best for: Teams that want a website chatbot plus a proper inbox for agents to work in. Check which tier unlocks escalation before you buy.

Chatbase

Chatbase is an AI chatbot platform trained on your documents, links, and text. Its integration list is the widest in this category, covering Zendesk, Intercom, Freshdesk, Salesforce, HubSpot, Shopify, Slack, WhatsApp, and Instagram.

Best for: Teams that need Zendesk, voice, telephony, or a specific CRM integration without waiting for the top tier.

Botsonic

Botsonic is Writesonic's AI chatbot platform. You train a bot on your website and docs, then deploy it to your site plus WhatsApp, Facebook Messenger, Telegram, Slack, and WordPress. Its Agentic Actions and workflows let the bot complete tasks rather than only answer.

Best for: Teams that want messaging channels at the lowest entry price and do not need live chat handoff.

DocsBot

DocsBot is an AI chatbot builder trained on documentation, with source citations attached to answers. It focuses on retrieval accuracy for technical content rather than general website chat, and supports remote MCP connections.

Key features:

• Source citations are attached to every answer
• Remote MCP connections

• Knowledge base refresh on a monthly or weekly schedule by plan
• Slack, Messenger, WhatsApp, Telegram, and Zapier integrations

Cons:

Best for: Teams whose chatbot answers from technical docs and who need every answer to cite its source.

My AskAI

My AskAI is an AI support agent that runs inside the helpdesk you already use. It connects to Intercom, Zendesk, Freshdesk, Gorgias, and HubSpot, and answers from your help content. It is a different shape from SiteGPT, working inside the ticket inbox rather than as a widget on your website.

Key features:

• Runs inside your existing helpdesk with no migration
• Trains on help center articles, websites, Google Drive, and Notion
• Replies in 95+ languages
• Advanced actions, including refunds and cancellations
• AI CSAT scoring and auto-tagging
• Historic ticket training on the Scale plan

Pros:

• Human handoff is native, because the agent already works in your inbox
• 30-day free trial with no credit card required, the longest here
• Unlimited seats from the Scale plan
• The agent-assist copilot carries no seat charge

Cons:

• $199 a month entry price, more than three times SiteGPT's monthly Starter rate
• The advertised $ 0.10-per-ticket rate is the overage rate. Included tickets cost about $0.199 on Pro
• Branding removal and API, Slack, and Teams access each cost $49 a month extra on Pro
• Requires an existing helpdesk, so it is not a standalone website chatbot

Pricing: Pro is $199 a month with 1,000 tickets, 5 seats, and $0.12 per extra ticket. Scale is $499 a month with 2,000 tickets, unlimited seats, and $0.10 overage. Enterprise starts at $999 a month. Annual billing takes 33% off.

Best for: Support teams already running Zendesk, Intercom, or Freshdesk who want fewer tickets reaching a human agent.

How to choose

If the model split is the problem, choose Nivon. One credit equals one message on any of its AI models, so switching from a cheap model to a strong one does not cut your allowance by 90%.

If you want a free plan rather than a 7-day trial, choose Nivon, Chatling, Chatbase, SiteSpeakAI, or DocsBot. All five have free tiers that do not expire. SiteGPT and Botsonic offer trials only.

If you need live chat with human handoff, choose SiteSpeakAI for the inbox or Chatling for handoff with an AI summary. Check the tier first, because SiteSpeakAI gates escalation to the Pro tier.

If you need Zendesk, choose Chatbase or My AskAI. SiteGPT includes the Zendesk AI Agent only on Scale, at $429 per month.

If you train from GitHub, YouTube, and Dropbox, stay on SiteGPT. Its twelve training source types are the widest here, and Nivon covers none of those three. That is a real reason to keep it.

If lead generation is the main use case, stay on SiteGPT. Lead capture is built into the chat flow rather than added on, and it is the feature its marketing pages lead with.

If your questions arrive as support tickets, choose My AskAI, which automates customer support inside your existing helpdesk.

Frequently asked questions

What is the best SiteGPT alternative?

It depends on what is not working. For a predictable allowance regardless of the AI model, Nivon charges 1 credit per message, starting at $12 a month. For built-in live chat and an agent inbox, SiteSpeakAI starts at about $29. For Zendesk and voice, Chatbase offers both from its Standard plan.

What is the cheapest SiteGPT alternative?

Nivon has the lowest entry price at $12 a month and the lowest cost per message at about $0.004. Botsonic and Chatwith both start at $19, and Chatling at $25. Nivon, Chatling, Chatbase, SiteSpeakAI, and DocsBot all offer free plans, which SiteGPT does not.

How much does SiteGPT cost?

SiteGPT Starter costs $59/month, billed monthly, or $39/year, with up to 4,000 messages, 1 chatbot, 1,000 pages, and 1 team member. Growth costs $129 per month or $79 per year, with 10,000 messages, 2 chatbots, and 4 team members. Scale costs $429 per month or $259 per year, with 40,000 messages, 3 chatbots, and 10 team members. Enterprise pricing is custom.

Does SiteGPT have a free plan?

No. SiteGPT offers a 7-day free trial with onboarding and no permanent free tier. Nivon's free plan gives 150 messages a month with no credit card required; Chatling gives 200 AI credits; DocsBot gives 100; Chatbase gives 50; and SiteSpeakAI gives 30.

Is there a free alternative to SiteGPT?

Yes. Nivon's free plan includes 150 messages per month, one AI agent, and one team member, with no card required and no expiry. Chatling's free plan adds unlimited non-AI chats. DocsBot and Chatbase both have free tiers, though Chatbase deletes agents after 14 days of inactivity and DocsBot after 30.

How many messages does SiteGPT actually give you?

It depends on the AI model. The Starter plan allows up to 4,000 messages on GPT-4.1-mini or 400 on GPT-4.1. Growth allows 10,000 or 1,000, and Scale 40,000 or 4,000. SiteGPT publishes this split, and you can adjust the mix from your billing settings.

Is SiteGPT $39 or $59 a month?

Both figures are correct for different billing terms. Starter is $39 a month on annual billing, charged as $468 a year, and $59 billed monthly. The annual discount runs from 34% on Starter to 40% on Scale, which is why the two numbers differ so much.

Does the SiteGPT Starter plan include integrations?

No. Starter has no integrations, no API access, and no webhooks. It is a chatbot on your website and nothing else. Integrations begin on the Growth plan, and the Zendesk AI Agent requires the Scale plan.

Which SiteGPT alternatives include live chat and human handoff?

SiteSpeakAI includes a chat inbox and conversation history, with escalation from the Pro plan. Chatling includes live chat with an AI-generated summary for the agent to pick up. Nivon hands off with the full conversation thread attached. My AskAI handles it natively inside your helpdesk. Botsonic charges $199 a month for handoff.

Which one to pick

SiteGPT's twelve training source types and its built-in lead capture are genuine strengths. If you train a chatbot on content across GitHub, Notion, and Drive, and want the widget to capture leads, it is well-suited for that.

The catch is the model split. The 4,000-message figure on Starter assumes you answer everything with the mini model. Run GPT-4.1, and you get 400 for the same $59.

If you want the allowance to apply to one thing regardless of model, Nivon charges one credit per message across 20+ AI models, starting at $12 a month, with a free plan that does not expire.
