Your conversations,
automatically captured
and organized.
HarkenAI listens quietly in the background and turns your conversations into searchable insights — complete with summaries, action items, and contact intelligence.
No bots. No manual recording. No lost conversations.
Plus a public API and MCP server your agents can talk to.
The Problem
Conversations are where work
actually happens.
Important decisions happen in meetings, hallway conversations, phone calls, quick huddles, investor discussions, and customer calls. But most of those conversations disappear the moment they end.
Work gets repeated. Follow-ups fall through.
Important insights get lost.
The Solution
HarkenAI remembers your conversations.
Runs quietly in the background and automatically turns conversations into structured records.
A transcript
Word-for-word record
A clear summary
AI-generated overview
Action items
Next steps extracted
Key topics
Themes identified
People involved
Speaker detection
Contact intelligence
Emails & LinkedIn
Everything becomes organized and searchable.
How It Works
Four steps to total recall
Listen
HarkenAI runs quietly in the background on your device. It captures meetings, calls, discussions, and quick conversations.
No meeting bots. No setup.
Separate
Using dynamic conversation separation, HarkenAI automatically detects when conversations start and end.
No manual start or stop.
Understand
AI analyzes every conversation and extracts summaries, action items, decisions, key topics, and the people involved.
Remember
Every conversation becomes searchable across your entire history.
