Same docs-grounded answers from $29/mo — plus the assistant can act on the signed-in user's account.
SiteGPT trains a chatbot on your website content, priced at $59, $129 or $429 a month. Command+K starts at $29/mo, answers from the same kind of content with citations, and can additionally take actions inside your product as the signed-in user through your own hosted MCP server.

SiteGPT and Command+K both put an AI assistant trained on your content onto your site. SiteGPT is a question-answering chatbot: upload your pages, embed the widget, and visitors get answers, on plans from $59 to $429 a month. Command+K starts at $29/mo, answers from the same content with citations, and goes one step further — through your own hosted MCP server the assistant acts as the signed-in user, so requests like resending an invoice or rotating an API key are completed in the chat instead of being handed to support. Teams that only need a marketing-site FAQ bot will be fine with either; teams whose users are logged in and want work done pick Command+K.
SiteGPT trains a chatbot on your website and documentation content and embeds it on your site to answer visitor questions.
Pricing: Published plans at $59, $129 and $429 per month. Reviewers note that real monthly cost depends on model usage and message volume on top of the plan fee.
Recurring themes from published reviews on G2, Capterra, Trustpilot and TrustRadius — with the source for each, and what we do differently.
Reviews note that real monthly cost depends on model usage and message volume on top of the plan fee, so the advertised tier understates what a busy site pays.
Credits are prepaid and capped. Your monthly ceiling does not move because traffic moved.
SiteGPT is a question-answering chatbot. There is no model for acting as a specific signed-in user, so account-specific work stays with your support team.
Requests like resending an invoice or rotating an API key are completed in the chat, as the signed-in user, with an approval step on anything that writes.
These are recurring themes in publicly published reviews and comparisons of SiteGPT, not our own testing. Every claim links to where we read it. If something here is out of date, tell us and we will correct it.
Unpredictable bills are the single most common complaint across this whole category, not just SiteGPT. Here is why AI support bills multiply — and how prepaid credits with a hard cap remove the problem.
| Capability | SiteGPT | Command+K |
|---|---|---|
| Docs-grounded answers with citations | Yes | Yes |
| Takes actions in your product (tool calling) | No | via your hosted MCP server |
| Acts as the signed-in user | No | JWT or end-user OAuth |
| Entry price | $59/mo | $29/mo |
| Cost predictability | Plan fee plus model usage and message volume | Prepaid credits, no metered overage |
| Your API published as an MCP server | No | OpenAPI in, hosted MCP out |
| Meter & bill AI usage to your customers | No | Yes |

Yes. Both embed an AI assistant trained on your content. Command+K starts lower at $29/mo, uses prepaid credits with no metered overage instead of usage that varies with traffic, and adds tool calling so the assistant can act as the signed-in user through your own hosted MCP server.
Command+K's entry plan is $29/mo against SiteGPT's $59/mo, and Command+K's credits are prepaid with a ceiling you set, so the monthly maximum is fixed in advance rather than moving with model usage and message volume.
If all you need is a chatbot on a public marketing site, SiteGPT is a simpler product with fewer concepts to learn. Command+K's extra capability — identity, tools, approvals, MCP hosting — is only worth it if your users are signed in.
