The best SiteGPT alternative is PepoChat

Short answer

People usually look for a SiteGPT alternative for one of three reasons. The first is the trial: no free plan, a card-only 7-day trial, and a $59-a-month floor. The second is the model meter: new chatbots default to GPT-4.1, which uses ten times the allowance of GPT-4.1 mini, so Starter's 4,000 messages are 400 replies until you move a slider. The third is the plan ladder: integrations and the API start on Growth, the Zendesk AI agent and lead webhooks on Scale, and the badge costs $39 a month to remove.

This page compares the two products feature by feature, works the cost at two traffic levels, explains how a migration goes, and says plainly where SiteGPT is still the better choice. If you are weighing other chatbots trained on a website, the Chatbase alternative and CustomGPT.ai alternative pages cover the two closest products, and our guide to training a chatbot on your website and PDFs explains what any of these tools does with your content.

Who should switch from SiteGPT to PepoChat

The clearest signal is that you are managing a model slider instead of a support queue. SiteGPT shares one monthly allowance between GPT-4.1 and GPT-4.1 mini, and its plans-and-limits reference says one GPT-4.1 message uses as much of the allowance as ten GPT-4.1 mini messages. New chatbots default to GPT-4.1, so the 4,000 messages on the $59 Starter plan are 400 replies until you move the slider on the Usage page, and Growth's 10,000 are 1,000. If you have been trading answer quality against running out mid-month, PepoChat removes the lever: one model, OpenAI's gpt-4o-mini, and one reply counted as one reply.

The second signal is a team that wants to start without a card and a $59 commitment. SiteGPT has no free plan and its 7-day trial requires a card. PepoChat's free plan is a plan, not a trial: every feature is switched on, 200 replies renew each month, and when they run out new chats go to the team inbox instead of failing. The third signal is a chatbot that should do things. SiteGPT's documentation covers answers, leads and human support, but no order lookups or booking from the chat, and leads reach a CRM only through a webhook on the $429 Scale plan.

When SiteGPT is still the better choice

Start with channels, because they decide most comparisons. On Growth and above the same SiteGPT chatbot answers inside Slack, Facebook Messenger, Google Chat, Crisp, Freshdesk Messaging and Zoho SalesIQ; on Scale it installs as the AI agent inside Zendesk Messaging; and a $39-a-month add-on puts it on WhatsApp. PepoChat is a website widget and a hosted chat page with no WhatsApp, Messenger, Slack or Zendesk Messaging channels, so if customers write to you there, SiteGPT wins outright. It also wins on content scale: 1,000 pages on Starter, 10,000 on Growth and 50,000 on Scale, where a page is 2,500 cleaned characters, against PepoChat's 200-page crawl per source.

SiteGPT is also the stronger pick for developers and for procurement. Its API v2 ships with TypeScript, Python and Go SDKs, a CLI, a remote MCP server and, on Scale, webhooks, for managing chatbots and conversations from code; PepoChat has custom actions and a widget script, not a management API. On compliance, SiteGPT's security page reports a completed SOC 2 Type II examination, GDPR certification by DPLMC International, a HIPAA assessment with a Business Associate Agreement on Enterprise, and a signed DPA on request. PepoChat has published none of those documents. Add a choice of two models and custom responses, and SiteGPT is the right tool for a regulated or developer-led team.

SiteGPT vs PepoChat: a support week, side by side

Monday morning, forty conversations waiting. In SiteGPT they sit in Chat History, with an Attention view for the escalated, unread and thumbs-down ones, and your team replies as an agent or takes the chat over, on Growth also from the iPhone app. In PepoChat they sit in the team inbox with statuses unresolved, escalated and resolved, each with the transcript and visitor details; operators reply as themselves and leave internal notes the visitor never sees. On Tuesday a customer asks where order 1042 is. SiteGPT answers from whatever shipping page you indexed, because it has no order lookup; PepoChat's Shopify or WooCommerce action fetches the order's payment and fulfilment status, as the order status guide shows.

Wednesday brings a frustrated customer who wants a person. Both tools escalate: SiteGPT when the visitor asks for a person, the situation is urgent or the visitor is frustrated; PepoChat when retrieval finds nothing relevant or the visitor asks for a person, as the human handoff guide describes. On Thursday a prospect asks for a demo. SiteGPT collects their email through its lead form; the booking happens later, by hand. PepoChat checks real availability on your PepoSmart calendar, shows slots in the visitor's local time and books the one they pick. On Friday, SiteGPT's analytics run from basic on Starter to conversation insights on Scale; PepoChat shows satisfaction votes and auto-labelled topics on every plan, with no volume charts.

What it actually costs

Take a store with about 700 replies a month, as of October 2026. On SiteGPT that is Starter at $59 a month, or $468 a year, which works out at $39 a month. The 4,000-message allowance covers 700 replies comfortably on GPT-4.1 mini but only 400 on GPT-4.1, so the default model pushes you to Growth at $129 a month for 1,000 GPT-4.1 replies. Starter also means one member and manual refresh only. On PepoChat, 700 replies is Starter at $49 a month, or $490 a year, with 2,000 replies, unlimited sources, three members, weekly re-fetching of web sources, the team inbox and every integration. The monthly stickers are close; what the money buys is not.

Now take a SaaS company at 2,000 replies a month. On GPT-4.1 mini, SiteGPT's Starter covers it at $59. On GPT-4.1 it needs 20,000 mini-equivalent messages: Scale at $429, or Growth at $129 plus two $39 Extra Messages add-ons, $207 in all, each add-on being 5,000 mini messages or 500 GPT-4.1 replies. PepoChat's Starter covers 2,000 replies at $49, and Growth at $149 gives 10,000. Removing the SiteGPT badge is a $39-a-month add-on on every plan; PepoChat removes its badge on Growth at no extra charge. Seats run 1, 4 and 10 by plan on SiteGPT and 1, 3 and 10 on PepoChat, with extra seats at $15 a month. Check the SiteGPT pricing page and the PepoChat pricing page before deciding.

How to move from SiteGPT to PepoChat

A migration rebuilds inputs, not conversations. List what SiteGPT was trained on: pages, files, text snippets, custom responses and connected apps. In PepoChat, add the website as a crawl of up to 200 pages and three levels with include and exclude filters, or import the sitemap; the add your website guide covers both, and a site over 200 pages is covered with two crawl sources, for example /docs and the rest. Upload the same PDF, DOCX, Markdown, HTML, TXT and CSV files, and turn custom responses into Q&A pairs or text snippets, which count as no sources at all. PepoChat's crawler respects robots.txt, which SiteGPT's crawler does not read, so check that nothing you need is disallowed.

Next, connect the tools and shape the agent. Each integration has a card with numbered steps; Zoho Desk, Salesforce, Slack and HubSpot connect with one-click OAuth, the others with a pasted key, and every action can be tested with real inputs before it goes live. Set the greeting, suggested questions and brand colour, write the agent instructions, and decide when lead capture asks for an email. Try it in the Test the agent drawer. Then swap the snippet: PepoChat is one script tag, described in the install guide, or the WordPress plugin. Keep SiteGPT until the inbox looks right, and export its leads to CSV first, because conversations do not transfer.

Where PepoChat's inbox, booking and actions change the outcome

For an online store, the difference is live data. SiteGPT answers from the pages you indexed: a shipping policy, yes, but not the status of order 1042. PepoChat's Shopify action returns payment and fulfilment status, the WooCommerce action finds orders by number or email, and when something needs a person the Zendesk, Freshdesk or Zoho Desk action files the ticket from the chat. For a SaaS team the win is Stripe plus Jira: the agent finds a customer's plan and renewal date, cancels at period end when asked, and turns a bug report into a Jira issue with the customer's email attached. All of this is on the free plan; the integrations page lists every action.

For a clinic, agency or consultancy, booking is the differentiator. SiteGPT collects a lead and emails your team; someone then opens the calendar. PepoChat connects to a PepoSmart calendar, lets you choose which meeting types the agent may offer and when, shows slots in the visitor's local time, re-validates the slot at booking so nothing is double-booked, assigns a host round-robin, creates the Google Meet, Zoom or Teams link and sends reminders, as the appointment booking guide explains. When that prospect returns weeks later and verifies their email, meeting memory lets the agent recall what they discussed. SiteGPT has no equivalent for either. Booking requires PepoSmart; Calendly and Cal.com are not supported directly.

Do SiteGPT and PepoChat work together?

Not on the same page, since a site runs one chat widget, but a split by channel is realistic. Put PepoChat on the website, where the inbox, booking and order actions matter, and keep SiteGPT for Slack, Messenger, Google Chat or the Zendesk Messaging widget, where PepoChat has nothing to offer. The cost is two knowledge bases to keep current and two sets of escalation rules, so the split only makes sense when the messaging volume is real. SiteGPT's docs note that dashboard replies do not reach Slack, Messenger, Crisp or Zendesk; your team answers inside those tools anyway.

The connective tissue is the helpdesk. If PepoChat files tickets in Zendesk, Freshdesk, Zoho Desk, HubSpot or Salesforce, and SiteGPT hands its Zendesk Messaging conversations to the same agents, your team works one queue regardless of where the customer started. PepoChat's Slack and Discord actions post an alert from a conversation, and the first time a contact is captured it can post a card to Slack and call a signed webhook that Zapier, Make or n8n receive, all on the free plan, where SiteGPT's leads webhook needs Scale. Against a single suite, the Zendesk alternative and Crisp alternative pages show what an all-in-one tool costs.

The bottom line for founders, support leads and agencies

For a founder, the arithmetic is short: PepoChat's free plan covers the website use case for as long as 200 replies a month covers you, and Starter at $49 is the next step; SiteGPT starts at $59 with a card and 400 default-model replies. For a support lead whose customers arrive through Slack, Messenger or a Zendesk Messaging widget, SiteGPT is the right tool and Growth at $129 is the fair comparison point. For an agency, PepoChat gives each client an isolated workspace with its own knowledge base, greeting and calendar on the free plan until volume justifies paying; SiteGPT sells 1, 2 or 3 chatbots per plan, so a fourth client means another plan.

Whichever way you lean, test with real traffic. Put PepoChat on the site for a month, watch the team inbox and the topics report, and compare the result with what SiteGPT would cost at the same volume on the model you would actually run.
