7 SiteGPT Alternatives for Website AI Chatbots (2026)

The best SiteGPT alternatives in 2026 are Elk, Chatbase, DocsBot, Chatling, CustomGPT, Tidio and Intercom Fin. If you want a free plan and messaging channels included, start with Elk or Chatling. If you need native helpdesk and e-commerce integrations, look at Chatbase. If your docs run to tens of thousands of pages, DocsBot or CustomGPT will hold more content.

SiteGPT does one thing well: it turns a website, even a very large one, into a chatbot that answers from that content and keeps itself up to date. People look for SiteGPT alternatives for a few common reasons. There's no free plan. WhatsApp and branding removal are paid add-ons. And the Starter plan has no integrations at all.

This guide covers what SiteGPT does well, where it falls short, and seven alternatives with honest notes on who each one fits. All pricing comes from each vendor's public pricing page, checked on October 4, 2026.

What SiteGPT does well (and where it falls short)

Strengths, based on SiteGPT's site:

• Large-site capacity. Up to 1,000 pages on Starter, 10,000 on Growth, 50,000 on Scale and 500,000 on Enterprise. SiteGPT counts 2,500 cleaned characters as one page.
• Automatic refresh. Monthly on Growth, weekly on Scale, daily on Enterprise, plus daily scans for new pages on Scale.
• Broad sources. Websites, sitemaps, YouTube, files, and connectors for Notion, Google Drive, Dropbox, OneDrive, Box and GitHub.
• Live-agent escalation and integrations with Crisp, Slack, Zendesk, Freshdesk and Zoho SalesIQ on higher plans.
• Compliance. SiteGPT says it is SOC 2 Type II examined, GDPR certified and HIPAA assessed.

Limitations:

• No free plan. There's a 7-day trial, and it requires a credit card.
• Starter has no integrations, one chatbot and one seat.
• Add-ons add up. Removing branding, WhatsApp, and each extra 5,000 messages are each +$39/month.
• Few chatbots per plan. Growth includes 2 chatbots and Scale includes 3.

SiteGPT alternatives compared

1. Elk

Elk trains an AI agent on your website, files and connected tools, then deploys it to a chat widget, WhatsApp, Instagram, Messenger and Slack. You connect each channel from the agent's Integrate tab.

Why it's a good SiteGPT alternative:

• Free plan with 50 chat credits/month. Paid plans start at $16/month billed annually.
• Website training three ways: crawl a domain, paste individual links, or import a sitemap, up to 500 pages per scrape. You can also upload files and connect Notion, Google Drive and Dropbox.
• Messaging channels are included on all plans, not sold as add-ons.
• Plugins for real work: Custom Actions that call your own API, Cal.com booking, Zendesk and Intercom ticket creation for human handoff, Slack alerts, forms and lead capture.
• Knowledge gap reports and automatic retraining on Growth ($80/month annual) and above.
• Model choice: GPT, Claude, Gemini, Grok, Llama, DeepSeek and Kimi models on paid plans.

Where SiteGPT is better: page capacity on very large sites and published compliance certifications. Elk limits knowledge base size by plan (2M to 50M) rather than by pages, and doesn't publish SOC 2 or HIPAA certification.

Best for: founders and small support teams who want one agent answering on their site and in WhatsApp or Instagram, without add-on fees. See Elk pricing.

2. Chatbase

Chatbase is one of the best-known tools in this category. It has a free plan with 50 message credits. Paid plans are $40 (Hobby), $150 (Standard) and $500 (Pro) per month, with 20% off yearly.

Strengths: a long native integration list (Stripe, Shopify, Zendesk, Salesforce, HubSpot, Intercom, Freshdesk, Gorgias and more), AI Actions, a built-in helpdesk, voice and telephony on Standard and up, and SOC 2 Type II, GDPR and HIPAA claims.

Weaknesses: one agent per plan, with each extra agent costing $25/month. Branding removal is a $99/month add-on. Free-plan agents are deleted after 14 days of inactivity.

Best for: teams that need the bot to talk to Shopify, Stripe or a CRM natively. We compare it with Elk in detail in Elk vs Chatbase.

3. DocsBot

DocsBot focuses on documentation and support content.

Pricing: Free (1 bot, 50 source pages, 100 AI credits/month), Personal $49/month (5,000 pages, 5,000 credits), Standard $149/month (3 bots, 15,000 pages, 5 seats), Business $499/month (10 bots, 100,000 pages, unbranded widgets). Annual plans get two months free.

Strengths: high page limits for the price, Slack, Messenger, WhatsApp and Telegram from the Personal plan, Cal.com and Calendly scheduling, MCP support, and SOC 2 and GDPR on Business.

Weaknesses: the free plan doesn't include integrations, actions, analytics or chat history. Unbranded widgets only come on the $499 Business plan.

Best for: SaaS products with large help centers and API docs.

4. Chatling

Chatling is a low-cost builder with a visual workflow editor.

Pricing: Free (200 AI credits, 1 agent, 500,000 characters), Starter $25/month or $21/month annual (1,750 credits, 2 agents), Growth $75/month or $63/month annual (6,000 credits, 5 agents), Scale $295/month or $246/month annual (35,000 credits).

Strengths: WhatsApp, Instagram, Messenger, Telegram and Slack from Starter, a choice of many models, workflows, and cheap add-ons.

Weaknesses: branding removal is +$35/month below Scale. Zendesk and HubSpot integrations start at Growth. Premium models use far more credits per message, up to 25.

Best for: small businesses that want scripted workflows alongside AI answers.

5. CustomGPT.ai

CustomGPT.ai is built for large, document-heavy knowledge bases and puts citations first.

Pricing: Standard $99/month or $89/month annual (1,000 queries, 10 agents, 5,000 documents per agent). Premium $499/month or $449/month annual (5,000 queries, 25 agents). Enterprise is custom. There's a 7-day trial with a card required.

Strengths: source citations on every answer, support for many file formats and languages, many connectors (Shopify, Zendesk, Confluence, Notion, SharePoint on Premium), and SOC 2 Type 2 and GDPR claims.

Weaknesses: expensive per query, no free plan, and branding removal only on Premium.

Best for: knowledge-heavy teams such as legal, research and internal docs, where citations matter more than cost. See our full list of CustomGPT alternatives.

6. Tidio (with Lyro)

Tidio is a live chat and helpdesk tool with an AI agent called Lyro.

Pricing: Free plan, Starter $24.17/month and Growth from $49.17/month (both billed annually), Plus from $300/month. Lyro is a separate add-on starting at $32.50/month for 50 AI conversations.

Strengths: strong live chat, up to 10 seats on self-serve plans, WhatsApp, Instagram, Messenger and email on every plan, and Shopify-friendly flows.

Weaknesses: the AI is priced per conversation on top of the base plan, so costs grow fast with volume.

Best for: stores where human live chat is the main channel and AI handles overflow. We cover this tradeoff in our Tidio alternatives post.

7. Intercom Fin

Intercom sells seats from $29 to $132 per seat per month. Its Fin AI agent is billed at $0.99 per outcome. Fin can also run standalone on top of other helpdesks such as Salesforce, with a minimum monthly commitment.

Strengths: a mature helpdesk, workflows, reporting, and you only pay for outcomes.

Weaknesses: costs are hard to predict at scale, and it's too much for a small team that only needs a website bot.

Best for: support teams with real ticket volume who already use Intercom or want a full helpdesk.

How to choose

Ask these four questions in order:

1. Do you need a free plan to start? If yes, cross off SiteGPT, CustomGPT and Intercom.
2. Which channels matter? If WhatsApp or Instagram is a priority, check that it's included in the plan you can afford: Elk, Chatling, DocsBot, Tidio.
3. What should the bot do besides answer? Booking, ticket creation and order lookups need actions or plugins. Check exactly which ones ship natively.
4. How big is your content? Under a few thousand pages, any tool here works. Above 10,000 pages, compare page and storage limits carefully.

Then run the same 20 real customer questions through your top two or three choices. Our guide on training an AI chatbot on your website has a simple testing checklist.

Frequently asked questions

Does SiteGPT have a free plan?

No. SiteGPT offers a 7-day free trial on its self-serve plans, and a credit card is required. Alternatives with a permanent free tier include Elk, Chatbase, DocsBot, Chatling and Tidio.

What is the cheapest SiteGPT alternative?

Among paid plans, Elk Starter at $16/month billed annually and Chatling Starter at $21/month billed annually are the lowest entry prices in this list. Compare credits per message for the model you plan to use, because premium models consume more credits on every platform.

Which SiteGPT alternative supports WhatsApp without an add-on?

Elk includes WhatsApp, Instagram, Messenger and Slack in its plans. Chatling includes WhatsApp from its Starter plan, and DocsBot from its Personal plan. Tidio includes WhatsApp on every plan. SiteGPT sells WhatsApp as a $39/month add-on.

Is SiteGPT good for large websites?

Yes, this is one of its strengths. SiteGPT's Scale plan covers up to 50,000 pages and Enterprise up to 500,000, with automatic daily, weekly or monthly refresh. If you have a very large documentation site, it is worth testing.

Can I switch from SiteGPT without retraining?

Not directly. Every tool on this list builds its own index, so you re-add your website URL or sitemap and files. Crawling usually takes minutes. Plan time to re-test answers and recreate any custom prompts or escalation rules.

Conclusion

SiteGPT is a solid choice for large websites that need automatic refresh and compliance paperwork. For most small teams, though, the lack of a free plan and the add-on pricing for WhatsApp and branding are reasons to look elsewhere. Elk and Chatling cost the least and include messaging channels. Chatbase has the most native integrations. DocsBot and CustomGPT handle very large knowledge bases.
