HarkenAI

Harken listens all day so you never have to take notes again.

Start a session in the morning and let it run. Harken records hour after hour — back-to-back meetings, a full day of classes, a three-day conference — and turns it all into clean transcripts, summaries, and action items.

Long recordings are the whole point. An ultra-efficient audio engine streams your session in small pieces as you go, sipping battery instead of gambling everything on one giant file at the end. And when a day covers six different conversations, Harken finds the seams and splits them into separate sessions, each summarized on its own.

RECORD FROM YOUR WRIST

Your Apple Watch isn't a remote control. It's a second recorder.

• One press from the watch face. Add the Harken complication to your favorite face: raise your wrist, press once, you're recording. • It records on its own microphone, so your phone can stay in your bag or locked on a desk. Audio relays over automatically while you keep talking. • Start, pause, and stop from either device — whichever you reach for, both stay in sync. • Perfect for moments you'd never pull out a phone: hallway conversations, walk-and-talks, site visits, a question after class.

CONNECT THE AI YOU ALREADY USE

Your conversations belong to you, and Harken hands them straight to your own assistant.

• Hosted MCP server. Add Harken to Claude, ChatGPT, Cursor, or any MCP-aware app by signing in — nothing to install, no config file to edit. • Then just ask. "What did I commit to in yesterday's calls?" Your assistant searches your sessions, reads the transcripts, and answers from the real thing instead of guessing. • Six read-only tools: search sessions, open one, read a transcript, list recent days, search contacts, and get a link to the audio. • A public REST API and personal API keys for your own scripts and agents. • Build a second brain you own. Have your agent file every conversation into Obsidian, Notion, or markdown on your disk. Your context compounds with every meeting.
