Full Vapi profile and vendor sources · Checked 2026-09-02
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
Forethought: Platform access fee plus outcome-based usage. Optional add-ons and possible overages affect the total; request the included outcome volume and excess-usage rates in the proposal. 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 Forethought include past tickets; help center; web content; internal knowledge. 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. 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: Forethought: Pricing is quote-only; product availability and ownership/branding should be checked during procurement. Vapi: Total per-minute cost includes selected STT, LLM, TTS and telephony providers; more engineering is required than turnkey tools.
