Crewbly AI
Agents

Build an agent in five minutes.

Intelligent virtual assistants that communicate with your customers through voice, SMS, or chat — handling complete conversations automatically, just like a trained team member.

Pick your agent type

Four prebuilt configurations.

Or build your own. The platform ships with templates for Inbound, Outbound, Support, and Sales — pick the closest fit and customize.

01

Inbound

Answer every call, route to the right person, or handle the whole conversation end-to-end.

02

Outbound

Run automated outreach campaigns with answer / no-answer / voicemail branches.

03

Support

Triage, qualify, and resolve customer issues across SMS, email, and voice.

04

Sales

Qualify leads, book demos, and update your pipeline without a human picking up.

Anatomy of an agent

Six components. Endless combinations.

Every agent is the sum of these parts. Swap any of them without touching the rest.

System prompt

Identity, Style, Response Guidelines, FAQs, Task — the four-section structure that keeps your agent consistent.

AI model

25+ models from OpenAI, Google Gemini, and Anthropic Claude. Start with GPT-4.1 Mini for the best speed-cost-intelligence balance.

Voice

Cartesia, OpenAI, or ElevenLabs. Filter by accent, age, and gender. Tune speed, stability, clarity, and style exaggeration.

Channels

Phone, SMS, Email — multi-channel per agent. Plus website widgets in three styles: Chat + Voice, Button Only, or Orb.

Knowledge base

Drop in PDF, DOC, or TXT files — or hand the agent a URL to crawl. Multiple knowledge bases per business if you need them.

Live testing

Voice Test + Chat Test built in. Function-call logs, conversation rewind, error detection, and an insights panel.

AI providers

25+ models. Three families.

  • OpenAI
  • Google Gemini
  • Anthropic Claude

GPT-4.1 Mini is the recommended default. Upgrade for complex reasoning (GPT-5, Gemini 3.1 Pro, Claude Opus 4.6) or emotional nuance (GPT-4o, Claude Sonnet 4.6).

Voice providers

Three top TTS engines.

  • Cartesia
  • OpenAI
  • ElevenLabs

Filter by accent, age, gender. Tune speed, stability, clarity + similarity, and style exaggeration. Preview before you ship.

Where your agent shows up.

Phone (voice)

Assign one or more numbers. Inbound and outbound. Live voice conversations.

Same numbers as voice. Two-way text, drip campaigns, instant follow-ups.

Email

Branded sender identities. Outreach, support, automated sequences.
