Put it to work around the clock in 40+ languages, and grow from a single call to thousands without adding staff.

- Step 5

Core Concepts
A few simple ideas make the rest of these docs easy to follow:
| Concept | What it means | Guide |
|---|---|---|
| Agent | The "brain" of your phone conversation — the instructions, voice, and knowledge that shape how it talks. | Agent Configuration |
| Template | A ready-made agent built for a specific industry or use case. | Templates |
| Knowledge Base | Your business information (files or website pages) the agent uses to answer accurately. | Knowledge Base & Guardrails |
| Tools | Extra actions your agent can take mid-call, like transferring to a person or ending the call. | Tools Configuration |
| Voice | The personality and accent your agent speaks with. | Audio & Voice |
| Phone Number | The number your agent uses to make and receive real calls. | Phone Numbers |
| Provider | Outside services (AI models, speech, voices, phone carriers) connected to your account. | Integrations |
| Batch Call | Scheduled, spreadsheet-driven calling campaigns at scale. | Batch Call |
| Call Log & Transcript | A complete record of every call: audio, transcripts, and details. | Call Logs |
| Eval | Automated safety checks that catch harmful or off-script responses before they reach customers. | Evals |
For Developers
The same platform that powers the dashboard is fully available to your engineering team. ScaleAI works with the AI and phone services you already use, and every feature is also available through a well-documented API.
Bring Your Own Providers
ScaleAI doesn't lock you into one vendor. Connect the speech, AI, and phone services your team prefers — or the best fit for the job — through one Integrations dashboard, with 25+ integrations across 6 categories:
| Category | Examples |
|---|---|
| AI models | OpenAI, Anthropic, Google Gemini, Azure, Cerebras |
| Speech-to-text | Deepgram, AssemblyAI, Sarvam, Cartesia, SmallestAI |
| Text-to-speech | ElevenLabs, Cartesia, Sarvam, FishAudio, Rumik, Vakyam |
| Phone carriers | Twilio, Exotel |
| Scheduling | Cal.com, Calendly |
Connect a provider once and it's available across every agent — swap models or voices without rewriting your agent's setup.
API-First by Design
Everything in the dashboard runs on the same API. Your team can build, provision, call, and monitor directly through the interactive API reference — without ever opening the dashboard.
The full API is documented with runnable examples — your engineers can test every request before writing a line of code.
