What SiteGPT is (and what “alternative” means)

SiteGPT is an AI customer-support chatbot platform that trains on your website (and files / YouTube / cloud drives), embeds on your sites, escalates to a human on visitor request, and surfaces unanswered questions / knowledge gaps in analytics and digests — priced on chatbot / message / page / seat tiers with a GPT-4.1 vs GPT-4.1-mini quota split (primary: sitegpt.ai / sitegpt.ai/pricing).

An “alternative” might replace SiteGPT’s website-chatbot job, or solve a different emphasis (cite+refuse + miss pile + unresolved-free + Shopify at /shop) while sharing the “train on my site” starting point. SiteGPT remains valid when you want that platform surface and will size the message meter (Q+A = 2 messages; GPT-4.1 ~10× mini).

Rinhelp is a site-grounded cite+refuse widget + shared inbox (miss pile) + one script tag + unresolved-free $29/300. Shopify via custom OAuth at /shop: WISMO returns order name, closed-set fulfillment status, tracking company/number/url (miss → refuse + handoff); refunds run refundCreate after human approval. Keep the desk; add the widget beside your stack when that is the gap.

1. Rinhelp — best when the job is cite+refuse + miss pile

Rinhelp indexes your site; answers with citations; refuses when it can’t; every chat lands in a shared inbox (miss pile); installs with one script tag.

• How it bills: $29 / 300 / $0.10; unresolved free; no seats (pricing).
• Best for: small team / founder; public site or docs; Shopify at /shop; wants SiteGPT-alternative category browse but actually needs grounded refuse + content-gap inbox.
• Shopify (custom OAuth at /shop): WISMO: order number + email → order name, closed-set fulfillment status, tracking company/number/url; miss → refuse + handoff. Refunds: request lands in the shared inbox → human approve → then refundCreate.
• Miss-loop contrast (short): SiteGPT surfaces unanswered questions via weekly digest / knowledge-gap tooling (Growth+). Rinhelp flags unanswered threads in the shared inbox as a content backlog.
• The catch: Rinhelp is a cite+refuse widget + shared inbox (unresolved-free billing). Message/page/chatbot platform meters live on SiteGPT / Chatbase / CustomGPT / DocsBot.
• Our pick framing: Our pick for the cite+refuse / miss-pile job among people shopping SiteGPT alternatives. Deep 1:1 → /compare/sitegpt. Optional free poke: /tools hub.

2. Chatbase — closest credit-meter peer

Train on content, deploy widget/agent; message-credit pots; free tier; actions / helpdesk / voice on Standard+.

• Bill: Free 50 → Hobby $40/700 → Standard $150/4,000 → Pro $500/15,000; yearly ~20% off; add-ons $40/1k, $25/agent, $99 branding.
• Best for: teams that want free poke + multi-model credit forecasting + broader agent surface.
• The catch: model-weighted credit burn; branding removal expensive. Rinhelp’s unresolved-free resolution bill lives on the Rinhelp card. Deeper Chatbase 1:1 → /compare/chatbase. Phrase-split: /alternatives/chatbase owns the Chatbase shopping list.

3. CustomGPT.ai — docs / PDF / large-KB RAG

Agents over large document sets; query meters; storage/word caps; citations / anti-hallucination marketing (vendor claims — attribute, don’t invent scores).

• Bill: Standard $99 / Premium $499 monthly ($89 / $449 yearly-eff); 7-day trial card-required.
• Best for: heavy PDF / multi-source knowledge bases beyond a simple site crawl.
• The catch: query ceiling stops responses; heavier entry than SiteGPT Starter / Rinhelp $29. Rinhelp’s miss-pile shared inbox lives on the Rinhelp card.

4. DocsBot — free poke + AI credits / actions

Turn docs/site into a chatbot; AI credits; actions/skills on paid plans; free tier.

• Bill: Free → $49 / $149 / $499; credits model-weighted; DocsBot page ≈ 5k cleaned chars (different from SiteGPT’s 2,500).
• Best for: teams wanting free start + credit ladder with actions.
• The catch: credit multipliers vary by model; do not reprint DocsBot deflection % calculators as proof.

5. Wonderchat — AI + live chat hybrid

Support/conversion agent with native human handover / live chat hybrid positioning.

• Bill: Free → Basic ~$124/mo yearly framing → Scale ~$417/mo yearly; Enterprise custom; re-check monthly stickers at publish.
• Best for: teams that want AI answers and live chat in one product more than a pure SiteGPT-like message/page platform.
• The catch: pricing page yearly-default; credit/resolution framing differs from SiteGPT messages — don’t force 1:1 unit math.

How to choose

Choose Chatbase if you want a free tier + credit-meter FAQ/agent platform (and will model model-weighted burn + add-ons). Choose CustomGPT if your knowledge base is document-heavy and query/storage meters fit better than SiteGPT’s message/page caps. Choose DocsBot if you want a free poke and an AI-credit / actions ladder on docs/site content. Choose Wonderchat if AI + native live chat in one product matters more than a pure website-chatbot twin. Choose Rinhelp if you need cite+refuse answers from your site, a miss pile, one script-tag widget, unresolved-free billing, and Shopify at /shop (WISMO fields + human-approved refundCreate). Stay on SiteGPT if message/page/chatbot tiers, digests/knowledge-gap tooling, Growth+/Scale integrations (or Zendesk AI Agent on Scale) fit your traffic and you will size Q+A + model split honestly. Skip Rinhelp if your only need is multi-bot page quotas, agency white-label, or SiteGPT’s exact message-meter platform surface — that is SiteGPT / Chatbase / CustomGPT territory.
