Notes Are Captured but Never Processed

Every team captures notes. Almost no team processes them systematically.

Notes That Sit Unprocessed

You capture notes from meetings and calls, but rarely go back to extract what matters. Action items get buried.

Voice Recordings Untranscribed

You record important conversations, then never listen again. The insights stay locked in audio files.

Context Lost Between Tools

Decisions are scattered across docs, Slack, and email. No single source of truth for what was said and agreed.

AI Agents Can't Ask Humans

When an AI agent needs human judgment, there's no seamless bridge. Automation stops and waits for manual intervention.

Capture. Process. Act.

Simyl Listen processes every note through an AI pipeline — transcribing audio, extracting action items, generating summaries, and connecting AI agents with human judgment via SMS.

AI Processing Pipeline

Every note — voice or text — flows through an AI pipeline. Automatic transcription, summarization, action item extraction, and smart categorization. No manual processing needed.

Capture Anything

Type a note or upload audio up to 100MB. Direct-to-S3 upload from your browser means no server bottleneck and no file size headaches. Async processing with real-time status tracking.

Human-in-the-Loop Bridge

AI agents request human input via SMS and poll for answers. Designed for Simyl Code integration — the AI asks a question, a human responds by text, and automation continues.

Everything Your Notes Need

From voice capture to AI insights to human-in-the-loop integration — built for how teams actually work.

AI Summarization

Amazon Bedrock generates concise summaries from any note content. See the key points without reading the full text.

Audio Transcription

AWS Transcribe converts voice recordings to text automatically. Upload, wait, and get a full transcript.

Action Item Extraction

AI identifies decisions, follow-ups, and action items from your notes. Never lose track of what was agreed.

Smart Tagging

Notes are auto-categorized based on content analysis. Search and filter by tags to find what you need instantly.

Human-in-the-Loop API

REST API for AI agents to request human input. Simyl Code's Claude agent sends a question, a human replies via SMS, the answer is polled and returned.

SMS Integration

Outbound notifications and inbound responses via AWS SNS. Phone verification with OTP and configurable spend controls.

Passwordless Auth

Email OTP login via AWS Cognito and SES. No passwords created, stored, or managed. Entire attack categories eliminated.

Async Processing Pipeline

Notes move through pending, processing, and processed states. Track AI progress in real-time without blocking your workflow.

Why Simyl Listen?

vs. Note-Taking Apps

Note apps store your notes. Simyl Listen processes them — transcribing, summarizing, and extracting action items automatically.

vs. Meeting Transcription Tools

Transcription tools give you a wall of text. Listen gives you summaries, action items, and smart tags from any audio or text input.

vs. No Human-in-the-Loop

When AI agents hit a wall, they stop. Listen bridges that gap — AI asks a human via SMS, gets an answer, and keeps going.
