SiteGPT and Chatbase both train an AI agent on your own content, and they diverge on two decisions that matter more than any feature list: how usage is metered, and whether the agent is expected to answer or to act. SiteGPT counts plain messages and optimizes for 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 out of 5, and the gap is narrow because the two win on different axes. SiteGPT leads on content sources (12+ versus 6), metering predictability, price at matched volume ($948 versus $1,440 per year for 4,000 answers a month), and branding cost ($468 versus $1,188 per year). 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.

80%
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 are competing for that workload, which is why metering models are diverging.

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 we scored both platforms
Every figure below comes from each vendor's own pricing page and documentation, read on 25 July 2026, plus third-party review platforms for ratings. Ten criteria were scored from 1 to 5, weighted equally, with the reasoning stated next to each score so a reader who weights the criteria differently can 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. Scores that favor SiteGPT are tied to a specific verifiable number, and the three criteria Chatbase wins are stated as clearly as the ones it loses.
The scorecard
| 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, Slack, Zendesk, Crisp, Messenger, Google Chat, Freshchat, Zoho SalesIQ |
| Human escalation | 4 | 4 | Both escalate reliably. Chatbase has its own Help Desk with takeover; SiteGPT escalates on demand with notifications on every tier |
| Branding and customization cost | 5 | 3 | Branding removal is $39/mo 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 |
Content sources and training limits
SiteGPT ingests more source types and more total content above the entry tier. SiteGPT documents 12 or more source types: 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, which makes the comparison easy to get wrong:
| 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.
Metering: credits versus messages
A SiteGPT message is a reply to a customer. A Chatbase credit is a request to an AI model. That single difference explains 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 depending on the model chosen, and that an agent running an action makes two requests, consuming twice the credits, for one customer answer. 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 practical effect:
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 $39 per month. The number on the plan is the number of replies.
Neither model is dishonest. Credit metering reflects real underlying cost differences between models, and a team that runs a light model on simple questions may pay less per answer on Chatbase. The tradeoff is forecastability against granularity.
Pricing at matched volume
All figures are annual rates, shown per month and billed yearly, verified 25 July 2026. 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), 500 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) 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 buys 500 credits, while $39 per month buys 4,000 messages. Teams whose volume is genuinely under a few hundred answers a month will pay less on Chatbase Hobby.
Actions, channels, and voice
Chatbase is the stronger platform for an agent expected to do things. Its documentation covers calendar booking through Cal.com and Calendly, Stripe payments, Salesforce and Shopify lookups, Slack and web search actions, lead collection, and custom actions, with per-plan action limits of 5 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 integrates with Slack, Zendesk, Crisp, Messenger, Google Chat, Freshchat, and Zoho SalesIQ, and lists Intercom, WhatsApp, and HubSpot as coming soon rather than live. SiteGPT has no voice or telephony product. A team automating phone support should choose Chatbase and stop reading here.
Human escalation
Both platforms escalate to a person, and the architectures differ.
Chatbase escalates through an Escalate to Human action into its own native Help Desk (Standard and above) or a connected desk such as Zendesk, Freshdesk, Intercom, Salesforce, HubSpot, Help Scout, or Zoho, and human agents can take over an AI conversation directly.
SiteGPT escalates on demand: when a customer asks to talk to a person, the chat is handed off and the team is notified by email, webhook, Zapier or Slack, or the dashboard, with the transcript and captured contact details. Escalation is available on all tiers, and seats scale by plan. The escalation trigger is the customer asking, not a sentiment model deciding.

Use-case verdicts
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 cheapest paid entry point of the two, and the Free plan supports a genuine 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. Two chatbots on the $79 plan and $39 per month branding removal beat one agent plus $25 per extra agent plus $99 per month branding removal.
For predictable finance planning, choose SiteGPT. Messages are countable in advance; model-weighted credits with action multipliers are not.

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 plans.
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 500 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 on demand when a customer asks for a person and notifies the team by email, webhook, Zapier or Slack, and the dashboard, on all tiers.
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.
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 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.
