Do SiteGPT and AskVault use the same underlying LLM?

Neither vendor publishes a fixed model mix and both route to multiple providers depending on plan tier. Answer quality differs more from RAG architecture choices (crawler, chunker, retrieval) than from which LLM generates the final answer.

Which has better accuracy on technical content — SiteGPT or AskVault?

Roughly equivalent for short queries. AskVault's hybrid retrieval (vector + keyword) handles exact-match needs like error codes, SKUs, and API names better than SiteGPT's pure-vector search. Validate accuracy on your own content with a free trial of both before deciding.

Is AskVault more secure than SiteGPT?

Both meet baseline SaaS security expectations. AskVault has a HIPAA-eligible BAA path on Enterprise (via SOC 2/HIPAA-eligible infrastructure). AskVault also provides a signed Data Processing Agreement on Growth+ plans for GDPR compliance.

Where SiteGPT is solid

We'll start with the honest credit. SiteGPT does a few things well:

Polished onboarding UX. The setup flow is genuinely simple. Paste a URL, wait for indexing, embed the snippet. The product feels designed.
Solid widget customization. Out of the box theming options are richer than most competitors at the entry tier.
Active product cadence. SiteGPT ships features and the changelog moves regularly.
Established brand. Trusted by enough teams that you won't get heat for picking it.

If your single requirement is a website widget for a marketing site and you're spending in USD, SiteGPT is a reasonable choice.

Where AskVault wins

The clear-win categories.

1. Multi-channel, native

SiteGPT supports the widget natively, plus Slack, Messenger, Google Chat, and helpdesk hand-offs (Freshdesk, Zendesk, Crisp, Zoho SalesIQ). WhatsApp and Intercom are both listed as "coming soon" on SiteGPT's own integrations page — not shipped yet. Telegram, Discord, SMS, voice, and email are not in their stack.

AskVault has 13 channels native. Same agent, same knowledge base, same dashboard inbox. WhatsApp via Meta Cloud or Twilio with full media support. Telegram with a 30-second BotFather setup. Discord, SMS, voice (Twilio), email assistant (IMAP + SMTP), Intercom messenger pass-through, hosted page at your custom domain, REST API, and live-chat inbox.

For B2B SaaS that needs more than a marketing widget, this is the dimension that closes the deal.

2. Action skills, not just answers

SiteGPT's "actions" are webhook calls you wire up yourself. They work, but they're not policy-bounded. The agent can call out to your custom URL with the conversation context, and you do whatever you do with that.

AskVault ships 14 first-party action skills with policy guardrails the LLM can't override:

knowledge_search, escalate_to_human, collect_lead, collect_info
ticketing_router (Zendesk), sentiment_router
sdr_lead_qualifier (HubSpot), demo_scheduler (Calendly)
wismo_order_status (Shopify), wc_order_status (WooCommerce), cart_recovery
discount_negotiator (Stripe), subscription_manager (Stripe), custom_webhook

Each one has a per-chunk policy ceiling (your business rules) plus a global hard cap. The model proposes the action, the policy layer enforces the bounds.

3. Crawler quality

SiteGPT crawls with a headless browser. That works on every site but it's slow, because every page pays the full browser-render tax. A 1,000-page docs site takes about 50 minutes.

AskVault's crawler is HTTP-first: it uses a fast HTTP fetch where it can and escalates to a headless browser only when a site needs it. Same coverage, roughly 10x faster end-to-end, and it remembers which sites need a browser so repeat crawls stay fast.

For a 1,000-page Shopify catalog, the difference is real. SiteGPT takes about 50 minutes; AskVault finishes in about 5.

4. Transparent pricing

SiteGPT prices in USD with message-based caps, and the pay-monthly rate (no annual commitment) is $59/mo Starter, $129/mo Growth — the $39/$79 figures on their pricing toggle only apply if you prepay a year up front. The same add-on dynamics show up as you scale: white-label removal is a $39/mo add-on on any plan, and extra message blocks cost more on top of your plan cap.

AskVault: one flat fee per tier, with a monthly message-credit allowance. Free (14-day trial) / $39 / $99 / $249 / Enterprise. MB content is the single billing axis. No per-seat charges, no per-message overage bills, no upgrade-only-for-branding lever.

Billed in USD through Dodo Payments, our merchant of record, which handles global tax and compliance. Checkout is a hosted redirect and works the same in every country.

5. Answer quality

SiteGPT runs pure-vector retrieval. That's fine for paraphrased questions but it misses on exact-match needs, error codes, SKUs, API names, where the wording matters.

AskVault uses hybrid retrieval (vector + keyword) with a reranking pass, so the chunks that reach the model are the ones that actually answer the question. On technical and catalog content this is the difference between a confident citation and a near-miss.

Where SiteGPT might still be the right pick

Some honest cases where we'd send you to SiteGPT instead.

You only need a website widget and you're spending in USD. SiteGPT's onboarding is more polished and the brand is more established. The price-per-message math is fine if you stay on the entry tier.
You're already on SiteGPT and the migration cost outweighs the savings. If you've invested in custom flows and your current workload fits SiteGPT's pricing, the switch isn't worth the engineering hours.
Your procurement has a specific vendor-domicile requirement. SiteGPT's terms of service designate Delaware law as governing, but the company is publicly described as founded and operated out of India, not US-incorporated. If your legal team mandates a specific contracting jurisdiction, confirm SiteGPT's actual entity directly with them, and check the same against AskVault's contracting entity up front.

Migration from SiteGPT to AskVault

If you want to move:

Export your knowledge from SiteGPT. Per-file exports. Website content has to be re-crawled.
Re-crawl in AskVault. Paste your URL into the onboarding wizard. 90 seconds for 50 pages.
Connect channels. Add WhatsApp, Telegram, Slack as needed. Each takes under 5 minutes.
Swap the widget snippet. Replace SiteGPT's script tag with AskVault's. The placement (</body>-relative) is the same.

Run both in parallel during the transition. Hide the SiteGPT widget on routes where AskVault is live, cut over when you're confident.

Decision matrix

If you want a quick decision:

Solo founder, US, marketing site only, USD billing. SiteGPT is fine.
B2B SaaS, global, needs WhatsApp + Slack + widget. AskVault.
E-commerce store with order-status questions. AskVault (the Shopify and WooCommerce integrations are first-class).
Internal helpdesk (employees, not customers). Either works; AskVault's identity verification is stronger for authenticated-only access.
Need action skills like lead qualification, demo booking, discount-code logic. AskVault.

FAQ

Do both products use the same underlying LLM?

Neither vendor publishes a fixed model mix and both route to multiple providers depending on plan tier and workload. Answer quality differs more from RAG architecture choices (crawler, chunker, retrieval) than from which LLM is doing the final generation.

Which has better accuracy on technical content?

Roughly equivalent for short queries. AskVault's hybrid retrieval (vector + keyword) handles exact-match needs (error codes, SKUs, API names) better than pure-vector search. SiteGPT runs vector-only. We recommend validating accuracy on your own content with a free trial of both products.

Can I run both products in parallel during a trial?

Yes. They render in separate fixed-position containers. Use the Origin or hostname check in each widget config to limit them to different routes during the bake-off.

Is one more secure than the other?

Both products meet baseline SaaS security expectations (TLS 1.3, encryption at rest, audit logs, GDPR data deletion). AskVault has a HIPAA-eligible BAA path on Enterprise (via SOC 2/HIPAA-eligible infrastructure). SiteGPT's security disclosures are less detailed publicly.

What currencies and billing options does AskVault support?

Billed in USD through Dodo Payments, our merchant of record, which handles global tax and compliance. Checkout is a hosted redirect and works the same in every country. AskVault is GDPR-compatible for EU customers, with a public DPA available on Growth+ plans.
