Vapi

What Vapi helps you do

Vapi provides a developer platform for voice agents with model, speech and telephony connections. It suits teams who need to configure a call workflow and measure the whole stack’s cost.

Best for: Developer voice agents and call workflows.

A small task to try

1. Create a test assistant for a fictional shop FAQ
2. Use a web session without dialling real customers
3. Speak one clear question and one ambiguous question
4. Inspect transcript, tool actions and the total cost breakdown

Illustrative input: What time does the demo shop close? Only the supplied policy says 18:00 weekdays.

Illustrative expected result: A spoken policy answer; an ambiguous date should trigger clarification rather than a guess. This is an editorial example, not a recorded vendor test. Check it against your original material before using it.

Access and buying guidance

Vapi offers USD 5 starter credits followed by paid usage. Model, speech, telephony and optional packages can add charges; starter credits are not an ongoing free plan.

Platform fees do not represent the full speech, model and phone cost. Start with the smallest useful task; keep the original input and compare the result before committing to a larger workflow.

Alternatives for a different workflow

ElevenLabs: compare speech creation and voice-agent options. Tidio: choose text customer chat instead of telephony.
