Platform features

Every primitive Indian SaaS & D2C teams need to message customers — and bill for it.

Six categories, dozens of features, one workspace. Below is what ships in the box today. Everything is API-first and documented in OpenAPI.

Channels

One API. Every channel your customer is on.

  • WhatsApp Business via Gupshup — templates, sessions and media
  • SMS via MSG91 with full DLT (entity ID + template ID) handling
  • Voice IVR & click-to-call powered by Exotel
  • Transactional & marketing email via AWS SES with bounce / complaint tracking
  • RCS messaging and mobile push (FCM / APNS)
  • OTP API across SMS, WhatsApp and Email with retry routing

AI

LLM-powered replies, summaries and intent routing — built in.

  • AI Agents inside flows — drop-in node for LLM-generated replies
  • Intent detection that routes incoming messages to the right team
  • Auto-summarisation of long threads in the unified inbox
  • Bring your own model — OpenAI, Anthropic, or self-hosted endpoints

Automation

ManyChat-grade visual builder for India-priced volumes.

  • Drag-and-drop visual flow builder with triggers, branches and delays
  • Campaign scheduler with audience segments and throttled sends
  • CRM-native triggers — new contact, tag added, deal stage change
  • Dead-letter queue with replay UI for failed jobs

Billing

Charge in INR, raise GST invoices, meter every message.

  • Razorpay subscription plans and one-time top-ups
  • Auto-generated GST-ready PDF invoices with HSN codes
  • Per-message metering across all channels in one dashboard
  • Prepaid wallet mode with low-balance alerts

Security

Enterprise controls without enterprise contracts.

  • Connector credentials encrypted at rest with AES-256-GCM
  • Webhook payloads HMAC-SHA256 signed and verifiable
  • Workspace-level RBAC with admin, agent and viewer roles
  • Immutable audit log of every config and message-send action
  • Multi-tenant isolation — every query is workspace-scoped at the DB layer

Developer Experience

Built by devs, for devs. No SDK lock-in.

  • OpenAPI 3 spec + interactive Swagger docs at /docs
  • API keys with granular scopes and per-key rate limits
  • Outbound webhooks for delivery, reply, bounce and flow events
  • TypeScript-first monorepo and openly typed contracts
  • Sandbox workspace mode for safe integration testing
