MySiteGPT vs Knibble
Updated
The short version
An AI knowledge base and ChatGPT-powered chatbot that answers from your PDFs, docs, and URLs, with an embeddable widget.
Knibble positions itself as an AI-powered knowledge base, powered by ChatGPT: you feed it PDFs, documents, and web pages, ask questions across them, and optionally embed a chatbot widget on your site. It leans toward the internal knowledge-base and document-Q&A use case as much as the public website assistant one, with a Notion integration (as of June 2026 — check knibble.ai).
If you're evaluating a Knibble alternative specifically to put a trustworthy assistant on a SaaS site, MySiteGPT narrows the focus to one job and does it loudly: it answers strictly from your content with citations a visitor can open and verify, and when retrieval confidence is low it returns your honest fallback instead of guessing. For a technical audience reading your docs and pricing, "I don't know, here's how to reach us" beats a confident wrong answer about your API.
| Feature | MySiteGPT | Knibble |
|---|---|---|
| Cited answers | Every factual claim carries a [n] marker tied to the exact source page or document; visitors open a source card to verify. | Answers draw from your uploaded sources, but visitor-facing inline citations aren't presented as the central promise — confirm current behavior on knibble.ai. |
| When it doesn't know | Answers only from your content, never the open web; low-confidence queries return your configured fallback message and can capture an email, logged as an unanswered question to fix in one click. | ChatGPT-grounded over your data; exact fallback and gap-logging behavior isn't something we'll assert — verify on their site. |
| Content sources | Crawl a site URL, paste text, add Q&A pairs, or upload PDF/DOCX/PPTX/XLSX/CSV/HTML/TXT/MD; heading-aware ~500-token chunking. | Strong document and PDF focus plus web pages and a Notion integration — a genuinely good fit for doc-heavy or Notion-based knowledge. |
| Pricing | Flat $9.99/mo Pro with OpenAI included and managed, and a 14-day no-card trial. | Tiered plans reportedly starting around $15/mo as of June 2026, with BYOK unlocking more on higher tiers — confirm on knibble.ai. |
| Content sync | Auto re-crawl daily at a time you choose, so the bot tracks site changes. | Re-indexing and scheduled-sync specifics aren't something we'll assert — check their docs. |
| Lead capture | Collects an email in chat after a helpful reply, emails you the transcript, and fires a per-bot lead.created webhook to Slack/Zapier/Make/n8n. | Built around knowledge retrieval; structured lead capture with webhooks isn't a headline feature — verify on knibble.ai. |
| Trial & data | 14-day trial, no card. After trial the widget silently goes offline; bots, training, conversations and leads are kept 30 days to reactivate in one click. | Free tier and paid trials have existed historically; post-trial data handling isn't something we'll claim — check their terms. |
Pricing and features here were compared in good faith from public materials as of June 2026 and may have changed — confirm current Knibble plans and capabilities on knibble.ai before deciding.
Why SaaS builders choose MySiteGPT over Knibble
- Point it at your docs, changelog, and pricing pages; the daily re-crawl at a time you choose keeps answers current as you ship, so the widget doesn't quietly drift out of date.
- Cited answers plus the honest fallback are built for technical buyers: the assistant never invents an API limit or endpoint, and a low-confidence question returns your fallback and captures the email instead of bluffing.
- Flat $9.99/mo with a no-card trial suits a bootstrapped SaaS budget, versus tier-gated knowledge-base plans where the features you want sit a step up.
- Lead capture pipes straight into your dev workflow: an email alert with the transcript plus a per-bot lead.created webhook to Slack, Zapier, Make, or n8n, with a REST API for the rest.
When Knibble is the better pick
If your real need is an internal or research-style knowledge base — chatting across a pile of PDFs and documents, or working alongside Notion — Knibble is built closer to that shape and is worth a look, especially if document Q&A matters more to you than a citation-first public website widget with lead capture.

MySiteGPT vs Knibble: frequently asked questions
Is MySiteGPT a good Knibble alternative for SaaS?
Yes, if your goal is a public website assistant rather than an internal document workspace. MySiteGPT trains on your site, docs, and uploads, answers only from that content with openable [n] citations, returns an honest fallback when it's unsure, and captures leads via email and webhooks — all on a flat $9.99/mo plan.
How does MySiteGPT pricing compare to Knibble?
MySiteGPT is a flat $9.99/mo Pro plan with OpenAI included and managed (3,000 messages, 3 bots, 1,000 trained pages, branding removed) and a 14-day no-card trial. Knibble's tiers reportedly start around $15/mo as of June 2026 — check knibble.ai for current numbers, since both can change.
Does MySiteGPT show sources like Knibble?
MySiteGPT makes visitor-facing citations the core of the product: every factual claim carries a [n] marker tied to the exact source page or document, and visitors can open a source card to verify. Knibble draws from your uploaded sources too, but how prominently it surfaces inline citations to visitors is worth confirming on their site.
Do I need an OpenAI API key?
No — OpenAI is included and managed on the flat $9.99/mo Pro plan; there's nothing to configure, and MySiteGPT provides the retrieval embeddings too. Knibble has historically offered bring-your-own-OpenAI on higher tiers; verify current support on knibble.ai.
Is MySiteGPT a knowledge base tool like Knibble?
Not exactly. Knibble leans toward an AI knowledge base you chat with over PDFs and Notion. MySiteGPT is deliberately a website assistant: it embeds as a cited, streaming chat widget via one script tag in an isolated Shadow DOM, and pairs answers with lead capture. If you want an internal knowledge workspace, Knibble may fit better; for a public site widget, MySiteGPT is the tighter fit.
