AI Voice Agents & No-Code Builder

Build voice agents like you build slides—fast, visual, and no code

Design human-sounding AI agents that can handle real phone conversations, collect information, take actions, and route calls—without needing engineers or complex voice infrastructure.

Key capabilities:

  • Simple, intuitive UI: Business users can build and update agents without developer help.
  • Human-sounding conversations: Choose from premium voices and tune tone, style, and behavior.
  • Prompt + LLM controls: Configure model behavior, temperature, and response style to match your brand.
  • Dynamic variables: Use system variables (caller info, time, call metadata) and custom variables captured during the call to personalize responses
  • Tool calling + business logic: Let agents trigger actions and fetch data using API tools and custom functions.

Conversation Quality & Real-Time Call Experience

Conversations that feel natural—low latency, interruptible, and resilient

Sayin.ai is built for real-time phone conversations, not “wait-and-respond” bots. Calls feel smoother, faster, and more human.

Key capabilities:

  • Voice Activity Detection (VAD): Detect when callers speak and respond naturally.
  • Interruption handling: If the caller speaks mid-response, the agent stops and adapts immediately.
  • Resume from false interruption: If background noise triggers a false interrupt, the agent can continue seamlessly.
  • Preemptive response generation: Reduce perceived latency by preparing responses while the caller is still speaking.
  • Intelligent silence handling: Detect silence and prompt the caller (“Are you there?”), then gracefully end if needed.

Native Dialer & Outbound Campaign Automation

The first voice agent platform with a full dialer built in

Sayin.ai doesn’t just “talk.” It executes outbound calling at scale—directly from the platform UI. Launch automated outreach without buying a separate dialer or stitching tools together.

Key capabilities:

  • Outbound calling at scale: Run follow-ups, reminders, surveys, and collections without agents
  • Calling cadence control: Define retries, churns, schedules, and campaign behavior your way.
  • Pass context into calls: Inject dynamic variables (name, appointment time, ticket ID, balance due) to personalize outreach instantly.
  • Campaign monitoring: Track activity, outcomes, and performance from the dashboard.
  • Max call duration controls: Automatically end calls safely to prevent runaway conversations.

Telephony & Call Handling

Real phone operations—PSTN/VoIP, numbers, routing, and transfers

Deploy agents over real phone numbers and connect to your telephony provider without managing SIP complexity.

Key capabilities:

  • PSTN/VoIP support: Run inbound and outbound calls through real numbers.
  • Elastic SIP connectivity: Connect to any telephony provider for global reach and cost control.
  • Buy and manage numbers: Purchase numbers and attach agents (Twilio/Vonage support).
  • Inbound routing webhook: Route calls to the right agent and inject session context before the call begins.
  • Call transfer (cold & warm): Seamlessly hand off to human teams when needed—sales closers, support agents, escalation desks.

Observability, QA & Analytics

Know what happened on every call—with transcripts, recordings, and outcomes

Sayin.ai includes built-in visibility and QA tooling so teams can monitor performance, troubleshoot faster, and improve continuously.

Key capabilities:

  • Call logs UI: Filter calls by agent, outcome, time, status, and metadata.
  • Transcripts + playback: Review conversations with searchable transcripts and recordings.
  • Call recording controls: Configure recording at account or agent level.
  • Post-call structured analysis: Automatically generate summaries and structured JSON outcomes (intent, category, sentiment, success state).
  • Async export (CSV/XLSX): Export filtered call data for BI, QA audits, or reporting.

Integrations, Webhooks & Extensibility

Connect Sayin.ai to anything—without custom engineering

Whether you’re syncing with a CRM, triggering scheduling, or calling internal APIs, Sayin.ai makes voice agents action-capable.

Key capabilities:

  • Open integration model: Define HTTP tools with parameters, headers, and response mapping.
  • Tool invocation via LLM: The agent can call tools dynamically with structured arguments.
  • Inbound + post-call webhooks: Push call events, variables, recordings, and outcomes into your stack.
  • Webhook reliability: Retries and delivery status logs reduce failures and silent data loss.
  • Triggers (SMS/WhatsApp/Email): Automate confirmations, reminders, and alerts across channels.

Cost Control & Guardrails

Built to prevent bill surprises—control spend with confidence

Voice automation can scale quickly. Sayin.ai includes observability and guardrails so teams can forecast, monitor, and optimize usage.

Key capabilities:

  • Usage monitoring: Track minutes, outcomes, and trends.
  • Forecast and optimize: Spot cost drivers and refine workflows.
  • Max duration + silence control: Reduce wasted time and runaway calls.
  • BYOK model: Use preferred AI vendors and optimize cost per interaction.
