The app listens to how you say something—not just what you say—and uses that emotional context to make conversations richer and smarter.

Resonate applies speech emotion recognition (SER) models to incoming voice messages in real time, extracting paralinguistic features such as tone, pitch, cadence, and energy to classify emotional states (e.g., excitement, frustration, calm, urgency). These emotion labels are surfaced inline alongside transcriptions, enabling recipients to understand the sender's emotional intent before or instead of listening to the full audio. The system also feeds emotion signals into downstream features like adaptive UI theming, smart reply suggestions calibrated to emotional tone, and live communication coaching that nudges users toward more empathetic or effective responses. By embedding emotion as a first-class data type in the messaging layer, Resonate creates a feedback loop where users become more intentional communicators and the platform continuously improves its emotion models through implicit user corrections and engagement signals.

It's like having a best friend who whispers "heads up, they sound upset" before you read a text—except the best friend is an AI that never misses a cue.

Instead of building every AI feature from scratch, Resonate built a system where AI agents can be assembled like LEGO blocks—each one handling a piece of a complex task and handing off to the next.

Resonate has built a durable execution framework with Python and TypeScript SDKs that abstracts the complexity of orchestrating multiple LLM-powered agents across distributed systems. Each agent is defined as a composable function with registered dependencies, persistent state, and built-in retry/recovery logic, enabling recursive tool-augmented workflows where agents can call other agents, invoke external APIs, or pause for human-in-the-loop intervention. This infrastructure powers features across the product—from AI-generated video in Resonate Create (where one agent scripts, another generates visuals, and a third composes the final output) to smart reply generation in chat (where an agent reads conversation context, infers intent, and drafts contextually appropriate responses). The framework is LLM-agnostic, supporting prompt-based agent templates that can be swapped between model providers (OpenAI, Anthropic, open-source) without rewriting application logic. Centralized orchestration APIs manage lock states, execution queues, and observability, giving engineers full visibility into agent behavior and enabling rapid iteration on new agentic features.

It's like a relay race where each AI runner knows exactly when to grab the baton, what leg to run, and when to call a human coach onto the track if things get tricky.

You can dump all your voice messages from every chat app into Resonate and instantly search, read, or get a summary of anything anyone ever said to you—across all platforms.

Resonate's interoperability layer ingests voice messages exported from WhatsApp, Signal, Telegram, and other platforms, running them through an automatic speech recognition (ASR) pipeline that supports multiple languages (with Hindi confirmed as an early priority). Each voice message is transcribed, timestamped, and speaker-diarized where possible, then passed through an NLP summarization model that generates concise, searchable abstracts. The resulting text is embedded into a vector store using sentence-level embeddings, enabling semantic search—users can query by meaning rather than exact keywords (e.g., "that time Maria talked about the restaurant in Brooklyn" retrieves the relevant voice clip and transcript). Smart formatting post-processing structures transcriptions with paragraph breaks, punctuation restoration, and named entity recognition to make raw voice content as scannable as written text. This transforms historically ephemeral, unsearchable voice messages into a structured, queryable knowledge base, dramatically improving information retrieval and reducing the friction of voice-first communication.

It's like having a personal secretary who listens to every voice note you've ever received across every app, takes perfect notes, and can instantly find the one where your mom told you her secret recipe.
