Overview

Perplexity combines large language models with realtime web search to deliver fact based, up to date responses. With Bolna's Perplexity integration, you can build voice agents that access current information, verify facts, and provide answers grounded in recent web sources.

Perplexity is ideal for scenarios where voice agents need to provide current information about products, services, news, policies, or any domain where information changes frequently and accuracy is critical.

Features & Use Cases

Real Time Web Search
Perplexity searches the web in real-time to provide current, fact-based answers - crucial for information that changes frequently.

Source Attribution
Responses include source citations, allowing verification of information and building caller trust.

Reduced Hallucination
By grounding responses in actual web sources, Perplexity reduces AI hallucination compared to pure language models.

Current Information
Access upto date information about products, policies, news, and events without manually updating knowledge bases.

Factual Accuracy
Optimised for factual queries where accuracy is more important than creative or conversational responses.

Use Case: Product Information Hotline
Build agents that provide current product specifications, availability, and pricing by searching your website and catalog in real-time.

Use Case: Policy & Compliance Queries
Handle questions about policies, regulations, or procedures by searching current documentation and official sources.

Use Case: News & Events Information

Large Language Models

The LLM is the brain of your voice agent. It understands what callers say and decides how to respond. Bolna lets you swap between models like GPT-4o, Claude, and DeepSeek without changing your agent configuration, so you can optimize for speed, cost, or reasoning depth.

Browse

Telephony

Telephony providers connect your voice agents to the phone network so they can make and receive real calls. Bolna supports managed integrations with major carriers as well as bring-your-own-carrier via SIP trunking, giving you full control over call routing, number provisioning, and cost.

Speech-to-Text

Speech-to-text converts what callers say into text that your LLM can process. Transcription accuracy and latency directly affect how natural a conversation feels. Bolna supports streaming STT providers optimized for telephony audio, including specialized models for Indian languages.

Text-to-Speech

Text-to-speech turns your agent responses into spoken audio. Voice quality shapes how callers perceive your brand. Flat, robotic speech kills trust while natural, expressive voices build it. Bolna integrates with the fastest TTS providers so responses sound human and arrive without awkward pauses.

Browse

Tools & Workflows

Tools let your voice agents take action during a call, not just talk. Book a calendar slot, look up an order in Shopify, push a lead into your CRM, or trigger a multi-step automation in Zapier. These integrations turn voice agents from answering machines into workflow engines.
