AI receptionist for Indian businesses.
CALLSATHI is the AI receptionist for small and growing businesses. Take inbound calls 24×7, answer customer WhatsApp instantly, book appointments, and never miss a lead.
Fewer Missed Calls
AI receptionist catches every inbound call 24x7 — no more lost leads or unanswered customer queries.
Languages Supported
English, Hindi, Tamil, Telugu, Marathi and 99+ more — powered by Sarvam AI and GPT-4o.
Response Latency
Near-instant responses that feel natural and human — no awkward pauses or robotic delays.
Your business never sleeps. Neither should your phone lines.
Small and growing businesses in India lose customers every day to missed calls, slow WhatsApp replies, and overwhelmed front-desk staff. Hiring more receptionists is expensive. Training them takes time. And they still cannot work 24 hours a day in every language your customers speak. Callsathi AI changes this equation entirely. Powered by GPT-4o, ElevenLabs premium voices, and Sarvam AI for Indian languages, it delivers an AI receptionist that answers every call, responds on WhatsApp instantly, speaks your customers' language, remembers their preferences, and books appointments without ever taking a break. With 99.9% uptime SLA, approximately 600ms latency, and 98% response confidence, Callsathi AI is not a chatbot experiment — it is production-grade infrastructure for businesses that cannot afford to miss a single lead.

Setup takes 20 minutes, not weeks. Upload your business documents, configure your AI agent's voice and personality through the no-code Agent Builder, and launch. From that moment, every inbound call is answered, every WhatsApp message gets an instant reply, and every lead is captured — in your customer's language, with your brand's tone. The Smart Insights dashboard gives you real-time visibility into call volumes, sentiment scores, and conversion metrics. Emotion-aware handling ensures frustrated callers are treated with extra care and escalated to humans when needed. Whether you are a single-location clinic or a multi-city restaurant chain, Callsathi AI scales with your business without adding headcount.
Proven efficiency in numbers.
Visualizing the operational gap between traditional receptionist setups and Callsathi AI.
Response Latency (Lower is Better)
Callsathi's ultra-low latency response is powered by custom Groq inference models combined with ElevenLabs' Turbo speech generation, ensuring conversation flows naturally without awkward pauses.
Concurrent Call Capacity (Scalability)
While human receptionists face hard limits on physical capacity and legacy IVR queues place callers on hold, Callsathi AI provisions elastic virtual lines to handle unlimited calls simultaneously.
Engineered for Indian Multilingual Realities
Callsathi AI handles natural conversation including regional accents, dialect variations, and "Hinglish/Hitelugu" code-switching mid-conversation.
AI that calls, listens, remembers, and cares.
Callsathi AI is not a basic IVR or a scripted chatbot. It is a full-stack AI voice and WhatsApp agent that handles real conversations with human-like quality, emotional intelligence, and perfect memory — so your business never misses a call, loses a lead, or frustrates a customer again.
Intelligent Calling
Callsathi AI makes and receives calls autonomously with human-like conversation. The AI agent handles inbound queries, qualifies leads, books appointments, and follows up — all without human intervention. With approximately 600ms response latency and 99.9% uptime SLA, every call is handled with speed and reliability that no human team can match around the clock.
Client Memory & Personalisation
Every interaction is remembered. Callsathi AI retains customer preferences, past conversations, purchase history, and communication patterns to personalise every future interaction. When a returning customer calls, the AI already knows their name, their preferences, and their history — creating the kind of continuity that builds loyalty and trust without requiring the customer to repeat themselves.
Emotion-Aware Call Handling
Callsathi AI detects frustration, urgency, profanity, and emotional cues in real time. When a caller is upset or a situation escalates beyond the AI's scope, the system auto-adjusts its tone — becoming more empathetic and measured — and can seamlessly escalate to a human agent with full conversation context. The caller never feels abandoned, and the human agent never arrives cold.
Natural Conversations
Forget robotic, scripted responses. Callsathi AI speaks with human-like speech patterns including natural filler words, appropriate pauses, emotional tone awareness, and conversational cadence. Whether the caller speaks in Hindi, English, Tamil, Telugu, Marathi, or any of 99+ supported languages, the AI adapts its speech style and language fluidly — even handling code-switching within a single conversation.
From zero to live AI agent in four simple steps.
Upload Knowledge
Feed Callsathi AI your company documents, FAQs, product catalogs, pricing sheets, and call scripts. The RAG pipeline ingests and indexes everything with retrieval verification to ensure zero hallucination. Your AI agent learns your business inside out — every product detail, every policy, every common question — so it can respond with 98% confidence from day one.
Outcome: A fully indexed knowledge base powering accurate, hallucination-free AI responses about your business.
Configure Your Agent
Use the no-code Agent Builder to customise your AI agent visually. Choose the voice, language, tone, and personality that matches your brand. Set call handling rules — when to escalate, how to greet, what to prioritise. Configure multilingual support across English, Hindi, Tamil, Telugu, Marathi, and 99+ other languages. The entire setup takes as little as 20 minutes.
Outcome: A branded, multilingual AI agent configured to your exact business rules and customer experience standards.
Launch Campaigns
Go beyond inbound. Upload your client lists, set call descriptions and objectives, and launch outbound AI calling campaigns. Whether it is lead qualification, appointment reminders, payment follow-ups, or customer feedback collection, Callsathi AI executes campaigns autonomously with human-like conversation quality — reaching hundreds of contacts simultaneously while maintaining personalised interactions.
Outcome: Automated outbound campaigns running at scale with personalised, human-like AI conversations.
Monitor & Improve
Track real-time analytics including call volumes, sentiment scores, resolution rates, and conversion metrics through the Smart Insights dashboard. Auto-generated reports surface root cause patterns, customer sentiment trends, and performance bottlenecks. Use these insights to continuously refine your agent's responses, expand its knowledge base, and improve customer satisfaction over time.
Outcome: Continuous performance visibility with actionable insights driving ongoing improvement.

MedCare Hospitals
MedCare Hospitals was losing patient inquiries and appointment bookings outside of business hours and struggling with multilingual support across their locations.
