SiteGPT and Chatbase both train an AI agent on your own content. They differ on two decisions: how usage is metered, and whether the agent answers or acts. SiteGPT counts plain messages and focuses on answering from a large content base. Chatbase counts model-weighted credits and adds actions, voice, and telephony.
iShort answer
Scored across 10 criteria, SiteGPT averages 4.2 out of 5 and Chatbase averages 3.8. The gap is narrow because each wins on different criteria. SiteGPT leads on content sources (12+ versus 6), metering predictability, and price at matched volume: $948 versus $1,440 per year for 4,000 answers a month, both billed yearly. Branding removal costs $468 a year on SiteGPT yearly billing versus $1,188 on Chatbase. Chatbase leads on actions, voice and telephony, and third-party review depth. Choose SiteGPT for content-heavy answering, Chatbase for an agent that books, charges, or calls.
For regulated buyers there is an eleventh criterion. Chatbase lists HIPAA eligibility on Enterprise. SiteGPT signs a BAA on Enterprise and publishes it, so counsel can read the retention and breach-notice terms up front. Neither offers HIPAA below its top tier.

of common customer service issues will be resolved autonomously by agentic AI by 2029, up from low double digits in 2024, according to a Gartner forecast. Both platforms want that workload, and they price it in different ways.
Source: Gartner forecast, cited in Lorikeet CX resolution-rate benchmarksBoth platforms train on your content. Chatbase adds actions and voice. SiteGPT adds more sources and flat message counts.
Chatbase: an agent that acts
- Meters requests to the AI model as credits, weighted by model
- 1 AI agent per plan, extra agents at $25/mo
- Actions: Cal.com, Calendly, Stripe, Salesforce, Shopify, web search
- Voice and telephony from the Standard plan up
- Training text capped at 10, 20, or 40 MB by plan
SiteGPT: an agent that answers
- Counts messages, so the plan limit maps to replies
- 1 to 3 chatbots included by plan, no per-agent add-on
- 12+ content sources including cloud drives, GitHub, YouTube
- Auto-refresh and auto-scan keep trained content current
- 1,000 to 50,000 pages by plan, at roughly 2,500 characters per page
How were SiteGPT and Chatbase scored?
Every figure below comes from each vendor's own pricing page and documentation, plus third-party review platforms for ratings. Both pricing pages were re-read on 27 September 2026, including the Chatbase pricing FAQ that defines how credits are consumed. Feature documentation was read on 25 July 2026.
Ten criteria were scored from 1 to 5 and weighted equally. The reason for each score sits next to it, so you can reweight the criteria and recompute the result.
The criteria are content sources, content freshness, metering predictability, price at matched volume, actions and automation, channel coverage, human escalation, branding and customization cost, seats included, and third-party validation.
Disclosure: SiteGPT publishes this comparison. Each score that favors SiteGPT is tied to a number you can check in the sources at the bottom of the page. Chatbase wins three criteria outright.
Which platform scores higher overall?
| Criterion | SiteGPT | Chatbase | Why |
|---|---|---|---|
| Content sources | 5 | 3 | SiteGPT ingests 12+ types including Google Drive, Notion, Dropbox, OneDrive, SharePoint, Box, GitHub, YouTube, and help centers. Chatbase documents files, text, links and sitemaps, Q&A, Notion, and tickets |
| Content freshness | 5 | 4 | SiteGPT auto-refreshes monthly on Growth, weekly plus daily scan on Scale. Chatbase offers auto retrain from the Standard plan |
| Metering predictability | 5 | 3 | A SiteGPT message is one reply. A Chatbase credit is one model request, weighted by model, doubled when an action runs |
| Price at matched volume | 5 | 3 | 4,000 answers a month costs $948/yr on SiteGPT Growth versus $1,440/yr on Chatbase Standard |
| Actions and automation | 2 | 5 | Chatbase documents booking, payment, CRM, e-commerce, and custom actions. SiteGPT answers and escalates |
| Channel coverage | 3 | 5 | Chatbase adds voice, telephony, WhatsApp, Instagram, and Messenger. SiteGPT covers web on every plan, WhatsApp as a paid add-on, Slack, Crisp, Messenger, Google Chat, Freshchat, and Zoho SalesIQ from Growth, and Zendesk from Scale |
| Human escalation | 4 | 4 | Both escalate reliably. Chatbase has its own Help Desk with takeover. SiteGPT escalates on every tier with email and dashboard notifications |
| Branding and customization cost | 5 | 3 | Branding removal is $39/mo billed yearly ($59 monthly) on SiteGPT and $99/mo on Chatbase, where full white-label is Enterprise-only |
| Seats included | 4 | 3 | SiteGPT includes 4 seats at $79/mo and 10 at $259/mo. Chatbase includes 3 at $120/mo and 5 at $400/mo |
| Third-party validation | 4 | 5 | Tied at 4.8/5 on G2, with Chatbase carrying 24 reviews to SiteGPT's 12, plus 73 Capterra reviews |
| Average | 4.2 | 3.8 | Narrow gap, opposite strengths |
Which platform trains on more content?
SiteGPT ingests more source types and more total content above the entry tier. It documents 12 or more source types. They are websites, sitemaps, YouTube videos and channels, GitHub, raw text, file uploads (CSV, TXT, PDF, DOCX, PPTX, MD), Google Drive, Notion, Dropbox, OneDrive, SharePoint, Box, and help centers including Zendesk, Freshdesk, Intercom, Confluence, and Gitbook.
Chatbase documents files (PDF, DOC, DOCX, TXT), plain text, links and sitemaps, Q&A pairs, Notion, and support tickets. That set covers the common cases and omits cloud drives, repositories, and video.
The volume limits use different units, so compare them carefully.
| Tier | Chatbase training limit | SiteGPT training limit |
|---|---|---|
| Entry paid | 10 MB of extracted text (Hobby, $32/mo) | 1,000 pages (Starter, $39/mo), roughly 2.5 million characters |
| Mid | 20 MB (Standard, $120/mo) | 10,000 pages (Growth, $79/mo), roughly 25 million characters |
| High | 40 MB (Pro, $400/mo) | 50,000 pages (Scale, $259/mo), roughly 125 million characters |
Chatbase's own FAQ specifies that its limit measures "the total size of extracted text content, not file sizes." SiteGPT counts roughly 2,500 cleaned characters as one page. On that basis Chatbase Hobby is the more generous entry tier, and SiteGPT is more generous at every tier above it.
How do Chatbase credits compare with SiteGPT messages?
A SiteGPT message is one reply to a customer. A Chatbase credit is one request to an AI model, and one reply can use several. That gap causes most of the forecasting complaints about credit-based platforms.
Chatbase's pricing FAQ states that each request to the AI model costs a number of credits that depends on the model chosen. An agent running an action makes two requests for one customer answer, so it consumes twice the credits. Auto-recharge then adds credits at $40 per 1,000 when the balance drops below a threshold you set.
A verified G2 reviewer described the effect in practice:
The credit system can be a bit tricky to wrap your head around at first. Since different AI models burn through credits at varying speeds, it's tough to nail down exactly how many you'll need each month.
SiteGPT's allowances are 4,000 messages on Starter, 10,000 on Growth, and 40,000 on Scale, with an extra 5,000 messages available at $59 per month billed monthly, or $39 billed yearly. The number on the plan is the number of replies.
Credit metering reflects real cost differences between models. A team that runs a light model on simple questions may pay less per answer on Chatbase. What it gives up is a bill it can forecast. CustomGPT meters the same way, and the SiteGPT vs CustomGPT comparison works through what an unpublished credits-per-message rate does to a budget.
Is SiteGPT or Chatbase cheaper?
SiteGPT is cheaper at matched volume, and Chatbase is cheaper at the entry point. All figures are annual rates, shown per month and billed yearly, verified on both pricing pages on 27 September 2026. SiteGPT's monthly rates are $59, $129, and $429. Chatbase advertises 20% off yearly plans and SiteGPT advertises up to 40% off, so annual-to-annual is the fair comparison.
| Scenario | Chatbase | SiteGPT | Annual difference |
|---|---|---|---|
| Cheapest paid entry | Hobby, $32/mo ($384/yr), 700 credits, 2 seats | Starter, $39/mo ($468/yr), 4,000 messages, 1 seat | Chatbase costs $84/yr less |
| 4,000 answers per month | Standard, $120/mo ($1,440/yr), 3 seats | Growth, $79/mo ($948/yr), 10,000 messages, 4 seats | SiteGPT costs $492/yr less |
| Two bots | Standard + extra agent, $145/mo ($1,740/yr) | Growth, $79/mo ($948/yr), 2 chatbots included | SiteGPT costs $792/yr less |
| Unbranded widget at mid tier | Standard + branding removal, $219/mo ($2,628/yr) | Growth + branding removal, $118/mo ($1,416/yr) | SiteGPT costs $1,212/yr less |
| High volume | Pro, $400/mo ($4,800/yr), 15,000 credits, 5 seats | Scale, $259/mo ($3,108/yr), 40,000 messages, 10 seats | SiteGPT costs $1,692/yr less |
46% less per year on an unbranded mid-tier setup
Chatbase Standard ($1,440/yr) plus branding removal ($1,188/yr) is $2,628/yr. SiteGPT Growth ($948/yr) plus branding removal ($468/yr, the yearly add-on rate) is $1,416/yr, a saving of $1,212 per year with 2.5x the message allowance and one more seat.
Chatbase wins the entry-price comparison on headline number and loses it on allowance: $32 per month billed yearly buys 700 credits, while $39 per month billed yearly buys 4,000 messages. Teams under a few hundred answers a month will pay less on Chatbase Hobby.
Can Chatbase take actions and answer phone calls?
Yes. Chatbase is the stronger platform for an agent that has to do things. Its documentation covers these actions: calendar booking through Cal.com and Calendly, Stripe payments, Salesforce and Shopify lookups, Slack and web search, lead collection, and custom actions. Plans allow 5 actions on Hobby, 8 on Standard, and 12 on Pro.
Chatbase also covers more customer-facing channels. Voice and telephony are included from Standard, with 10 concurrent calls on Standard and 20 on Pro, and its integration list includes WhatsApp, Instagram, and Messenger alongside helpdesks and e-commerce platforms.
SiteGPT's chat integrations start on Growth: Slack, Crisp, Messenger, Google Chat, Freshchat, and Zoho SalesIQ. Zendesk needs Scale and Zendesk Suite Professional or above. Starter has no chat integrations.
SiteGPT sells WhatsApp as a paid add-on on any plan, at $59 a month billed monthly or $39 a month billed yearly. The chatbot reads text only on that channel, and the details are on the WhatsApp AI chatbot page. Intercom and HubSpot are not live. SiteGPT has no voice or telephony product, so a team automating phone support should choose Chatbase.
Can Chatbase hand off to a human?
Yes, and so can SiteGPT. The two route the conversation differently.
Chatbase uses an Escalate to Human action. It sends the chat into its own native Help Desk (Standard and above) or into a connected desk such as Zendesk, Freshdesk, Intercom, Salesforce, HubSpot, Help Scout, or Zoho. Human agents can also take over an AI conversation directly.
SiteGPT escalates when the visitor asks for a person. The team gets the transcript and any captured contact details. Email and dashboard notifications work on every tier. Slack needs Growth, and webhooks and Zendesk need Scale.
If handoff quality is your deciding criterion, the roundup of AI chatbots with human handoff scores a wider field on it.

Should you choose SiteGPT or Chatbase?
Choose SiteGPT to answer from a large, changing content base. Choose Chatbase for an agent that books, charges, or calls.
For content-heavy sites, choose SiteGPT. A documentation set, help center, or knowledge base spread across Google Drive, Notion, GitHub, and a help center is ingested natively and re-crawled on a schedule.
For quick single-source bots on a tight budget, choose Chatbase. Hobby at $32 per month billed annually is the cheaper paid entry point. The Free plan is enough for a proof of concept.
For agents that book, charge, or look up orders, choose Chatbase. Documented actions for Cal.com, Calendly, Stripe, Salesforce, and Shopify have no SiteGPT equivalent.
For phone and voice automation, choose Chatbase. SiteGPT does not offer voice.
For agencies and multi-brand teams, choose SiteGPT. Growth includes two chatbots at $79/mo, and branding removal is $39/mo, both billed yearly. Chatbase charges $25 per extra agent and $99/mo for branding removal.
For predictable finance planning, choose SiteGPT. You can count messages in advance. Credits vary by model and double when an action runs.

Frequently asked questions
Basics
What is the main difference between SiteGPT and Chatbase? SiteGPT is built around answering from a large body of content, and Chatbase is built around an agent that also takes actions. SiteGPT ingests 12 or more source types and counts plain messages. Chatbase ingests files, links, text, Q&A pairs, Notion, and tickets, meters model requests as credits, and adds documented actions such as calendar booking, Stripe payments, and CRM writes, plus voice and telephony on Standard and above.
Does either platform offer a free plan? Chatbase has a permanent Free plan with 50 message credits per month, and its pricing page notes that agents on that plan are deleted after 14 days of inactivity. SiteGPT does not offer a free plan and instead provides a 7-day free trial on all self-serve plans, with a credit card required.
Which platform supports voice and phone calls? Chatbase supports voice and telephony on the Standard plan and above, with 10 concurrent calls on Standard and 20 on Pro. SiteGPT does not offer a voice or telephony agent, so a team that needs phone automation should choose Chatbase.
Pricing and limits
Which is cheaper, SiteGPT or Chatbase? SiteGPT is cheaper at matched message volume, and Chatbase is cheaper at the entry point. Chatbase Hobby is $32 per month billed annually for 700 credits, undercutting SiteGPT Starter at $39 per month for 4,000 messages. At 4,000 answers a month, Chatbase Standard costs $120 per month ($1,440 per year) while SiteGPT Growth costs $79 per month ($948 per year) and includes 10,000 messages, 2 chatbots, and 4 seats.
How do Chatbase message credits work? A Chatbase message credit is consumed per request to the AI model, and the number consumed depends on the model chosen. Chatbase documents that an agent running an action makes two model requests for a single answer, consuming twice the credits. Credits do not map one to one onto customer conversations.
How many AI agents and seats does each plan include? Chatbase includes 1 AI agent on every plan from Free through Pro, with extra agents at $25 per month each, and 1, 2, 3, and 5 workspace seats on Free, Hobby, Standard, and Pro. SiteGPT includes 1 chatbot and 1 seat on Starter, 2 chatbots and 4 seats on Growth, and 3 chatbots and 10 seats on Scale.
Which platform can train on more content? SiteGPT trains on more content above the entry tier. Chatbase caps extracted training text at 10 MB on Hobby, 20 MB on Standard, and 40 MB on Pro. SiteGPT allows 1,000 pages on Starter, 10,000 on Growth, and 50,000 on Scale, where a page is roughly 2,500 cleaned characters.
Capabilities
Does Chatbase or SiteGPT have better human handoff? Both escalate to a person, with different architectures. Chatbase uses an Escalate to Human action into its own Help Desk or a connected desk such as Zendesk, Freshdesk, or Intercom, and supports agent takeover of an AI conversation. SiteGPT escalates when the visitor asks for a person and notifies the team by email and the dashboard on every plan. Slack notifications need Growth, and webhooks and the Zendesk integration need Scale.
Which platform is better for regulated industries? Both gate compliance features to their top tier. Chatbase lists SSO, audit logs, and HIPAA eligibility on its custom-priced Enterprise plan. SiteGPT makes a signed HIPAA BAA and a signed DPA available on Enterprise, with HIPAA not included on Starter, Growth, or Scale.
The practical difference is how much you can check before you talk to sales. SiteGPT publishes its standard BAA with the retention window, five-business-day breach reporting, subcontractor flow-down, and the commitment that PHI never trains AI models, plus docs describing what a covered workspace changes. Budget for those changes: connected apps (Notion, Google Drive, GitHub, and the rest) and chat integrations are unavailable on a HIPAA workspace, and PHI has to stay out of training content entirely.
Fit
Which is better for a documentation-heavy SaaS company? SiteGPT is the better fit for documentation-heavy SaaS. Its Growth plan covers 10,000 pages and connects directly to Google Drive, Notion, GitHub, and help centers including Zendesk, Freshdesk, Intercom, Confluence, and Gitbook, and auto-refresh keeps those sources current as docs change.
Which is better for an agency running chatbots for clients? SiteGPT is usually the better fit for agencies on cost grounds. Removing branding costs $39 per month billed yearly ($59 billed monthly) on SiteGPT versus $99 per month on Chatbase, and SiteGPT includes 2 chatbots on Growth and 3 on Scale, while every Chatbase plan includes 1 agent with extras at $25 per month. Full white-labeling with SSO is Enterprise-only on Chatbase.
Which platform has better third-party ratings? The two are tied on G2 score and Chatbase has the larger review base. Chatbase holds 4.8 out of 5 from 24 reviews on G2 and 4.3 out of 5 from 73 reviews on Capterra. SiteGPT holds 4.8 out of 5 from 12 reviews on G2. Figures verified July 2026.
