The table below preserves each vendor’s scope and qualifiers. An unlisted feature is unverified here; it is not a claim that the feature is unavailable.
Before you decide
Help Scout AI: Helpdesk subscription per user plus monthly AI resolution charges. AI Answers is an additional usage cost, so the per-user rate alone does not represent the total AI support bill. Vapi: Usage-based hosting plus provider costs for transcription, language models, speech and telephony. Bring-your-own keys move provider billing to your own account. Includes 10 concurrent calls; extra lines cost $10/month each. Scale uses a quoted platform fee and committed volume under an annual contract. 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.
The recorded sources for Help Scout AI include Help Scout Docs; knowledge base; approved articles. For Vapi, they include prompts; custom functions; documents; external APIs. 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.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Which source types and sync schedules are supported? Can users inspect citations? How are unanswered questions reviewed? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Help Scout AI: AI Answers relies on Docs quality and is a separate metered cost on top of helpdesk plans. Vapi: Total per-minute cost includes selected STT, LLM, TTS and telephony providers; more engineering is required than turnkey tools.
