Before buying

PolyAI vs SiteGPT: buying questions

How should I compare PolyAI and SiteGPT pricing?

PolyAI: Per-minute voice usage at a negotiated rate, including ongoing maintenance, improvements and 24/7 support. Confirm call volumes, telephony and contract commitments in the proposal. SiteGPT: Subscription by chatbot, source-page, team-member and message allowances. Starter includes 1 bot and 1,000 pages; Growth 2 bots and 10,000 pages; Scale 3 bots and 50,000 pages. Extra 5,000-message packs cost $59/month. Refresh schedules and integrations vary by tier. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.

Can PolyAI and SiteGPT use my existing knowledge?

The recorded sources for PolyAI include call-center knowledge; policies; CRM/business systems; procedures. For SiteGPT, they include website pages; sitemaps; PDFs/files; Q&A. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.

What should I test in a PolyAI vs SiteGPT pilot?

Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Can it cite or restrict answers to approved knowledge? What happens when the agent is uncertain? Which actions can it complete beyond answering? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: PolyAI: Quote-only and implementation-led; not a self-serve chatbot builder. SiteGPT: Message and page caps apply; annual toggle can make headline prices differ from monthly billing.

Language and multilingual support checks

A multilingual claim alone does not establish quality for your language. Test real questions, source material, channels, handoff, and the management interface.

DocsBot documents multilingual answers, including Japanese. Verify quality with your own content and workflow before buying.

For other providers, the precise Japanese and multilingual coverage shown here is not independently verified. Confirm the plan, model, channel, and handoff with each vendor.
